The volume of the triangular prism is 42 in³.

What is a triangular prism?

In geometry, a triangular prism is a three-sided polyhedron with a triangle base, a translated copy, and three faces joining equal sides. A right triangular prism is oblique if its sides are not rectangular.

We know that

Volume of Prism (V) = Area of triangle * Height of Prism

Area of triangle = (Base * Height) / 2

Area of triangle = (4 * 3) / 2

Area of triangle = 12 / 2

Area of triangle = 6 in²

Using this, we get

⇒V = 6 * 7

⇒V = 42 in³

Hence, the volume of the triangular prism is 42 in³.

The area of this trapezoid is 25.5ft What is the height of the trapezoid? Show your work. I REALLY NEED THIS FAST, I HAVE LESS THAN 3 HOURS.

Answers

The height of the trapezoid is 2.84ft.

What is area ?

In mathematics, area is the measure of the amount of space inside a two-dimensional shape or surface. It is usually expressed in square units, such as square inches, square meters, or square feet.

The formula for the area of a trapezoid is:

A = (1/2)h(b1 + b2)

where A is the area, h is the height, b1 and b2 are the lengths of the two parallel bases.

We can rearrange this formula to solve for the height:

h = 2A / (b1 + b2)

We are given that the area of the trapezoid is 25.5ft. However, we also need to know the  of the two parallel bases in order to find the height.

Assuming that you have a diagram or other information that provides the lengths of the two bases, you can plug in the values for A, b1, and b2 and solve for h using the formula above.

For example, if we assume that the trapezoid has bases of length 4ft and 7ft, we can plug these values into the formula to get:

h = 2(25.5) / (4 + 7) = 2.84ft

Therefore, the height of the trapezoid is 2.84ft.

IS AND POLYNOMIALS Factoring a quadratic with leading coeffic Factor. 3z^(2)+20z-7

Answers

Factored form of 3[tex]z^{2}[/tex] + 20z - 7 is (3z - 5)(z - 2)(3z - 7)

Yes, factoring a quadratic with a leading coefficient is possible. The leading coefficient of your polynomial is 3. To factor this quadratic, use the following steps:

1. Divide the leading coefficient (3) into the constant term (-7). This will give you a quotient of -7/3 and a remainder of 1.

2. Create two terms that multiply together to give -7/3 and add to 20/3. In this case, the two terms are -4/3 and -5/3.

3. Write the quadratic as a product of two binomials.

3[tex]z^{2}[/tex] + 20z - 7

= 3[tex]z^{2}[/tex] + (4/3)(-3z) + (5/3)(-3z) - 7

= 3[tex]z^{2}[/tex] - 9z - 4z - 7 = 3[tex]z^{2}[/tex] - 13z - 7


4. Factor the binomials by grouping.

3[tex]z^{2}[/tex] - 13z - 7 = (3[tex]z^{2}[/tex] - 10z) - (3z - 7)

5. Factor each binomial.

(3[tex]z^{2}[/tex] - 10z) = (3z - 5)(z - 2)

(3z - 7) = (3z - 7)(1)


Therefore, the factored form of 3[tex]z^{2}[/tex] + 20z - 7 is (3z - 5)(z - 2)(3z - 7).

If \( f(x)=5 x, g(x)=-2 x+1 \), and \( h(x)=x^{2}+6 x+8 \), find \( g[h(2)] \). Question 4 If \( f(x)=5 x, g(x)=-2 x+1 \), and \( h(x)=x^{2}+6 x+8 \), find \( h[f(9)] \).

Answers

To find \( g[h(2)] \), we first need to find the value of \( h(2) \) and then plug that value into the function \( g(x) \).

Step 1: Find \( h(2) \)
We plug in the value of 2 for x in the function \( h(x)=x^{2}+6 x+8 \) to get:
\( h(2)=(2)^{2}+6 (2)+8 \)
Simplifying, we get:
\( h(2)=4+12+8 \)
\( h(2)=24 \)

Step 2: Find \( g[h(2)] \)
Now we plug in the value of 24 for x in the function \( g(x)=-2 x+1 \) to get:
\( g[h(2)]=-2 (24)+1 \)
Simplifying, we get:
\( g[h(2)]=-48+1 \)
\( g[h(2)]=-47 \)

Therefore, \( g[h(2)]=-47 \).

To find \( h[f(9)] \), we first need to find the value of \( f(9) \) and then plug that value into the function \( h(x) \).

Step 1: Find \( f(9) \)
We plug in the value of 9 for x in the function \( f(x)=5 x \) to get:
\( f(9)=5 (9) \)
Simplifying, we get:
\( f(9)=45 \)

Step 2: Find \( h[f(9)] \)
Now we plug in the value of 45 for x in the function \( h(x)=x^{2}+6 x+8 \) to get:
\( h[f(9)]=(45)^{2}+6 (45)+8 \)
Simplifying, we get:
\( h[f(9)]=2025+270+8 \)
\( h[f(9)]=2303 \)

Therefore, \( h[f(9)]=2303 \).

We have the following response after answering the given question: function Hence, the quarterly growth rate is almost 4.08%.

what is function?

Mathematicians research numbers, their variants, equations, forms, and related structures, as well as possible locations for these things. The relationship between a group of inputs, each of which has a corresponding output, is referred to as a function. Every input contributes to a single, distinct output in a connection between inputs and outputs known as a function. A domain, codomain, or scope is assigned to each function. Often, functions are denoted with the letter f. (x). The key is an x. There are four main categories of accessible functions: on functions, one-to-one capabilities, so many capabilities, in capabilities, and on functions.

[tex]P(t) = P0 * e^(rt) (rt)[/tex]

Where q is the quarterly rate of increase, [tex]q = (1 + r)(1/4) - 1.[/tex]

[tex]q = (1 + 0.17)^(1/4) - 1 ≈ 0.0408\sP(t) = 1100 * e^(0.17t) (0.17t)[/tex]

Q is equal to round[tex]((1 + 0.17 ** (1/4) - 1, 4)[/tex]

P0 = 1100

math.log(1 + q) = r

(q * 100, 2)

4.08 P(t) = P0 * e(rt), where r is the natural logarithm's base and P0 is the beginning population (approximately 2.71828).

Where q is the quarterly rate of increase, q = (1 + r)(1/4) - 1.

[tex]q = (1 + 0.17)^(1/4) - 1 ≈ 0.0408\sP(t) = 1100 * e^(0.17t) (0.17t)[/tex]

We may convert the quarterly growth rate to a percentage and round to the closest hundredth of a percent to get the percentage rate of change every quarter:

(q * 100, 2)

4.08

Determine the range of the quadratic function. Give your answer as an ineq f (x) = 7x2 – 10x + 10

Answers

Answer:

Step-by-step explanation:

Given: [tex]f(x) = 7x^{2} -10x+10[/tex]

To find: Range of the function

To find the range of the function, write the quadratic equation in the form of vertex form of parabola, that is:

[tex]f(x) = a(x-h)^{2} +k[/tex]

If a > 0, range of the function of [k, ∞)

[tex]f(x) = 7x^{2} -10x+10=7(x^{2} -\frac{10}{7} x+\frac{10}{7} )[/tex]

[tex]f(x) = 7(x-\frac{5}{7} )^{2} +\frac{45}{7}[/tex]

by comparing this expression with the vertex form of parabola, we can say that the range of the function is [[tex]\frac{45}{7}[/tex], ∞)

The range of the quadratic function f(x) = 7x2 – 10x + 10 is {y | y ≥ 315/49}.

The range of a quadratic function is the set of all possible values that the function can take on. To find the range of the given quadratic function f(x) = 7x2 – 10x + 10, we need to find the vertex of the function, which is the point at which the function reaches its maximum or minimum value.

The x-coordinate of the vertex of a quadratic function is given by:
x = -b/(2a)

Where a and b are the coefficients of the quadratic term and the linear term, respectively. In this case, a = 7 and b = -10, so:
x = -(-10)/(2*7) = 10/14 = 5/7

Now, we can plug this value of x back into the function to find the y-coordinate of the vertex:
y = 7(5/7)2 – 10(5/7) + 10 = 175/49 – 50/7 + 10 = 175/49 – 350/49 + 490/49 = 315/49

So the vertex of the function is at the point (5/7, 315/49).

Since the coefficient of the quadratic term is positive, the function opens upwards, and the vertex is the minimum point of the function. Therefore, the range of the function is:
y ≥ 315/49

In inequality form, the range of the quadratic function f(x) = 7x2 – 10x + 10 is {y | y ≥ 315/49}.

Compare and contrast the four different conic sections (orbits). Discuss their
eccentricities.

Answers

The four different conic sections are the circle, ellipse, parabola, and hyperbola. They are called conic sections because they are formed by the intersection of a plane and a cone.

What are conic circles?

Circle: A circle is formed when the plane intersects the cone at an angle perpendicular to its axis. The circle has an eccentricity of 0, which means the distance between any point on the circle and its center is always the same.

Ellipse: An ellipse is formed when the plane intersects the cone at an angle that is not perpendicular to its axis. The ellipse has an eccentricity between 0 and 1, which means the distance between the two foci and any point on the ellipse is constant.

Parabola: A parabola is formed when the plane intersects the cone parallel to one of its sides. The parabola has an eccentricity of 1, which means it has a single focus point.

Hyperbola: A hyperbola is formed when the plane intersects the cone at an angle that is greater than the angle formed by the cone's side and its axis. The hyperbola has an eccentricity greater than 1, which means the distance between the two foci and any point on the hyperbola is constant.

In summary, the eccentricity of a conic section describes how stretched or elongated the shape is. A circle has an eccentricity of 0, an ellipse has an eccentricity between 0 and 1, a parabola has an eccentricity of 1, and a hyperbola has an eccentricity greater than 1.

A pendulums horizontal distance from rest is given by the function det d(t)= 7 sin (πt/3 - 2) inches, where t is the time in seconds. a. Find the velocity of the pendulum in 6 seconds. b. Find the acceleration of the pendulum in 6 seconds.

Answers

The velocity of the pendulum is approximately -2.45 inches/second.

The acceleration of the pendulum is approximately 5.13 inches/second².

To find the velocity and acceleration of the pendulum, we need to find the first and second derivatives of the function d(t).

a. The velocity of the pendulum is given by the first derivative of the function d(t):

v(t) = d'(t) = 7 * (π/3) * cos(πt/3 - 2)

To find the velocity at t = 6 seconds, we simply plug in 6 for t:

v(6) = 7 * (π/3) * cos(π(6)/3 - 2) = 7 * (π/3) * cos(4) ≈ -2.45 inches/second

So the velocity of the pendulum at 6 seconds is approximately -2.45 inches/second.

b. The acceleration of the pendulum is given by the second derivative of the function d(t):

a(t) = d''(t) = -7 * (π/3)² * sin(πt/3 - 2)

To find the acceleration at t = 6 seconds, we simply plug in 6 for t:

a(6) = -7 * (π/3)² * sin(π(6)/3 - 2) = -7 * (π/3)² * sin(4) ≈ 5.13 inches/second²

So the acceleration of the pendulum at 6 seconds is approximately 5.13 inches/second².

a) A point on the rim of a 8 centimeter diameter wheel is traveling at 115 m/sec. What is the angular velocity of the wheel in radian per second? (1m = 100 cm)
b) A bicycle wheel has the diameter of 18 inches. If the wheels are rotating at 125 revolutions per minute, what is the linear velocity (to the nearest miles per hour) of the bicycle? (5280 feet = 1 mile.)

Answers

The linear velocity of the bicycle is approximately 6.68 miles per hour.

a) The angular velocity of the wheel can be found by using the formula:
ω = v / r
where ω is the angular velocity, v is the linear velocity, and r is the radius of the wheel.
In this case, v = 115 m/sec and r = (8 cm / 2) = 4 cm = 0.04 m.
So, the angular velocity of the wheel is:
ω = (115 m/sec) / (0.04 m) = 2875 radian per second.



b) The linear velocity of the bicycle can be found by using the formula:
v = ω * r
where v is the linear velocity, ω is the angular velocity, and r is the radius of the wheel.
In this case, ω = 125 revolutions per minute = (125 * 2π) / 60 = 13.09 radian per second and r = (18 inches / 2) = 9 inches = 0.75 feet.
So, the linear velocity of the bicycle is:
v = (13.09 radian per second) * (0.75 feet) = 9.82 feet per second.
To convert this to miles per hour, we can use the conversion factor 5280 feet = 1 mile:
v = (9.82 feet per second) * (60 seconds / 1 minute) * (60 minutes / 1 hour) * (1 mile / 5280 feet) = 6.68 miles per hour.
So, the linear velocity of the bicycle is approximately 6.68 miles per hour.

Answers

(a) The simple regression model is a reasonable description of the association between the two variables, as all conditions for the reliable use of the SRM are satisfied.

(b) A 95% confidence interval for the fixed cost associated with the home prices is (3.35, 4.38). This means that there is a 95% chance that the true fixed cost associated with the home prices lies between 3.35 and 4.38 thousand dollars.

(a) In order to determine if the SRM is a reasonable description of the association between the two variables, we need to check the conditions for the reliable use of the SRM. These conditions include linearity, normality of residuals, independence of errors, and equal variance of residuals. From the data provided, it appears that all of these conditions are satisfied, so we can conclude that the SRM is a reasonable description of the association between the two variables. Therefore, the correct answer is A. All the conditions for the SRM are satisfied.

(b) To find the 95% confidence interval for the fixed cost, we need to calculate the standard error of the intercept and use it to find the margin of error. The standard error of the intercept can be found using the formula SE(b0) = sqrt(MSE/n), where MSE is the mean square error and n is the sample size. Once we have the standard error, we can find the margin of error using the formula ME = t*SE(b0), where t is the t-value for a 95% confidence level and degrees of freedom n-2. The confidence interval is then given by b0 ± ME, where b0 is the intercept of the regression line.

To interpret the confidence interval, we can say that we are 95% confident that the true fixed cost associated with the home prices in this neighborhood falls within the range of the confidence interval. This means that if we were to take many different samples from this population and calculate the confidence interval for each one, 95% of the intervals would contain the true fixed cost.

Side DC has a value of 4.

What is triangles?

Similar triangles are triangles that have the same shape but different sizes. Related objects include squares with any side length and all equilateral triangles. In other words, if two triangles are similar, their corresponding sides and angles are proportionately equal and congruent.

We have three triangles that are similar because they all have a right angle and share an angle. Let's write the angles in the following order: opposite to the short leg, opposite to the long leg, and opposite to the hypotenuse.

CBD CAB BAD CBD

Alternatively, as ratios,

BA:AD:BD = CB:BD:CD = CA:AB:CB

We also understand

AD + CD = AC

(AD+CD):AB:CB = BA:AD:BD = CB:BD:CD = CB:BD:CD

(AD+CD)/CB=CB/CD

Let CD equal x.

(5 +x )/6 = 6/x

(5+x)*x = 6*6

5x + x² = 36

x² + 5x - 36 = 0

x² + 9x -4x -36 = 0

x(x+9 ) -4 (x +9 ) = 0

y = (-3/2)x + 2

The second equation is 2x−3y=7. We can also rearrange this equation to get y in terms of x:
3y = 2x - 7
y = (2/3)x - (7/3)

Now we can graph both equations on the same coordinate plane. The first equation has a y-intercept of 2 and a slope of -3/2, while the second equation has a y-intercept of -7/3 and a slope of 2/3.

After graphing both equations, we can see that they intersect at the point (2, -1). This means that the solution to the system of equations is x = 2 and y = -1.

Therefore, the solution to the given system of equations is (2, -1).

Give your answer in metres to 1 d.p. b) Each metre of the chain has a mass of 1.8 kg. Using an exact value for n, calculate the total mass of the chain to the nearest kilogram. n 36 m 23 Not drawn accurately​

Answers

The total mass of the chain is approximately 76.82 kg

What is the Pythagorean theorem?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

We can use the Pythagorean theorem to solve this problem. According to the diagram, we have:

n² = 36² + 23²

n² = 1296 + 529

n² = 1825

n = √(1825) ≈ 42.68

So the length of the chain is approximately 42.7 meters (rounded to 1 decimal place).

To find the total mass of the chain, we can multiply the length by the mass per meter:

mass = 42.68 x 1.8 ≈ 76.82

Therefore, the total mass of the chain is approximately 76.82 kg (rounded to the nearest kilogram).

Maxine is projecting her cash flow budget for the coming month for her photography business. She charges $70 per session and is anticipating 20 sessions. Her beginning cash balance is $2,000. She is anticipating $900 in rent and $600 in supplies. What is her projected ending cash balance?

Answers

Maxine's projected ending cash balance is $1,900.

What is the basic arithmetic operations?

The basic arithmetic operations are addition, subtraction, multiplication, and division.

Maxine's projected cash inflow from 20 sessions at $70 per session is:

20 sessions x $70/session = $1400

Her total projected cash inflow is therefore $1400.

Her projected cash outflow is $900 for rent and $600 for supplies, for a total of:

$900 + $600 = $1500

Her beginning cash balance is $2,000.

To calculate her projected ending cash balance, we need to subtract her projected cash outflow from her projected cash inflow and add her beginning cash balance:

Projected ending cash balance = Beginning cash balance + Projected cash inflow - Projected cash outflow

Projected ending cash balance = $2,000 + $1,400 - $1,500

Projected ending cash balance = $1,900

Therefore, Maxine's projected ending cash balance is $1,900.

Question 19 If $50,000 is invested in an account earning 5% compounded continuously, determine how long it will take the money to Wruble Write vour answer as an exact value.

Answers

It will take approximately 13.86 years for the money to double when it is invested in an account earning 5% compounded continuously.

To find out how long it will take for the money to double, we can use the formula for continuous compounding: A = Pe^(rt), where A is the final amount, P is the principal amount, r is the interest rate, and t is the time in years.

We are given that P = $50,000, r = 5%, and A = 2P = $100,000. We need to solve for t.

Plugging in the given values, we get:

$100,000 = $50,000e^(0.05t)

Dividing both sides by $50,000, we get:

2 = e^(0.05t)

Taking the natural logarithm of both sides, we get:

ln(2) = 0.05t

Solving for t, we get:

t = ln(2)/0.05

t ≈ 13.86 years

Therefore, it will take approximately 13.86 years for the money to double when it is invested in an account earning 5% compounded continuously.

What is inequality?

Inequality is when something is not equal in terms of rights, resources, opportunities or outcomes between different groups or individuals.

To determine if a point is a solution to an inequality, we can plug in the x and y values of the point into the inequality and see if it is true.

In this case, we plug in x=-1 and y=9 into the inequality:

2(-1)+9<-3

Simplify:

-2+9<-3

7<-3

This is not true, so (-1,9) is not a solution to the inequality.

A cube with edge length 8 is balanced on one of its vertices on a horizontal table such that the diagonal from this vertex through the interior of the cube to the farthest vertex is vertical. When the sun is directly above the top vertex, the shadow of the cube on the table is a regular hexagon. The area of this shadow can be written in the form a*
√b, where a and b are positive integers and b is not divisible by any perfect square larger than 1. What is the value of a + b?

Answers

The required value of a + b is 35.

The area of the shadow can be calculated by finding the area of the regular hexagon. The formula for the area of a regular hexagon is:

    A = (3√3)/2 * s^2,

where s is the length of one side of the hexagon.

Since the cube is balanced on one of its vertices, the length of one side of the hexagon is equal to the length of one edge of the cube, which is 8.  Therefore, the area of the shadow is A = (3√3)/2 * 8^2 = 64√3/2 = 32√3.

The value of a is 32 and the value of b is 3, so the value of a + b is 32 + 3 = 35. Therefore, the answer is 35.

a) 112.2 ft
b) 212.2 ft
c) 312.2 ft
d) 412.2 ft

Answers

A 12-ft high flagpole is standing vertically at the edge of the roof of a building with angle of elevation of 78°50'.  The height of the building is 312.2 ft (option c)



To find the height of the building, we can use the tangent function of the angle of elevation. The tangent function relates the opposite side (height of the building + flagpole) to the adjacent side (distance from the base of the building) of a right triangle.

The angle of elevation is given as 78° and 50'. We can convert this to decimal form by dividing the minutes by 60:

78° + (50'/60) = 78.833°

Let H = height of the building + height of the flagpole

Then,

tan(78.833°) = opposite/adjacent
tan(78.833°) = H/64 ft
H = 64 ft * tan(78.833°)
H = 324.2 ft

Therefore,

the height of the building = H - 12

                                            = 324.2 - 12 = 312.2 ft (option c)
