Find the domain and range of the function. (Enter your answers using interval notation.) f(x) = 9x² + 1

Answers

In interval notation, the domain and range of the function are:
Domain: (-∞, ∞)
Range: [1, ∞)

The domain of a function is the set of all possible values of x that can be plugged into the function. The range of a function is the set of all possible values of f(x) that can be obtained by plugging in values of x into the function.

For the given function f(x) = 9x² + 1, the domain is all real numbers, because any value of x can be plugged into the function. Therefore, the domain is (-∞, ∞).

The range of the function is the set of all possible values of f(x) that can be obtained by plugging in values of x into the function. Since the function is a quadratic with a positive leading coefficient (9), the graph of the function will be a parabola that opens upward. The minimum value of the function will occur at the vertex of the parabola, which is (0, 1). Therefore, the range of the function is [1, ∞).

Ms. Rekha spends 165.31 , inclusive of a sales tax of 15 percent ,on oranges . Calculate the original price of oranges

Answers

The original value of the oranges is 143.75.

What is Percentage?

A percentage is a number or a ratio that is expressed as a fraction of 100 i.e. out of 100.

In formula, x% of amount y = y*(x/100)

Given :

Tax paid by Rekha : 15%

Final Price paid by Rekha : 165.31

Let the original price of the oranges = x

The additional tax amount on oranges

           = 15% of original price of x

           = 15 * x / 100

           = 0.15 x

Total price paid by Rekha = Original price of orange + Tax amount

165.31 = x + 0.15x

165.31 = (1 + 0.15)x

165.31 = 1.15x

x = 165.31/1.15

x = 143.75

Thus, the original value of the oranges is 143.75.

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).

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.

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.

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).

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.

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.

Answers

The solution to the given system of equations, 3x+2y=4; 2x−3y=7 is (2, -1).

To solve the given system of equations graphically, we need to first graph each equation on the same coordinate plane and then find the point of intersection.

The first equation is 3x+2y=4. We can rearrange this equation to get y in terms of x:
2y = -3x + 4
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.

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

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.

Which n is equal to 427. I need the proof for the question

Answers

427.

The proof for the question is as follows:

A(n) is the arithmetic mean of the (positive) factors of n.

We want to find the n for which A(n) = 124.

Let F be the set of (positive) factors of n, and let f1, f2,..., fm be the elements of F.

The arithmetic mean of F is defined as A(n) = (f1 + f2 + ... + fm)/m.

Now, we have A(n) = 124. So, 124 = (f1 + f2 + ... + fm)/m.

Therefore, 124m = f1 + f2 + ... + fm.

This implies that f1 + f2 + ... + fm = 124m = 427.

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

Hence, the quarterly growth rate is almost 4.08%.

Tell whether (-1,9) is a solution to inequality. Hint: plug in the point. 2x+y<-3

Answers

No, (-1,9) is not a solution to the inequality 2x+y<-3.

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.

The value of a is 20, b is 40, c is 10 and d is 10√3

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

By using sine function we find the value of a

sin 45=a/20√2

1/√2 = a/20√2

20√2=a√2

a=20

Now let us find c

cos 45=c/(20√2)

1/√2×20/√2=c

10=c

sin30=a/b

1/2=20/b

b=40

Now we have to find d by cosine function

cos30=d/a

√3/2=d/20

d=10√3

Hence, the value of a is 20, b is 40, c is 10 and d is 10√3

The number representing the 6th grader participated in the field event is 120

What is a sample space?

A sample space is a collection or a set of possible outcomes of a random experiment.

The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events.

Given is a graph, showing the number of class students taking parts in different events,

We need to find the number of the 6th graders who participated in field event.

The sample size is 20 for who participated in field event, that means one unit is representing 20 participants

The sample number for 6th graders who participated in field event = 6

That means, the total number of the 6th graders who participated in field event = 20 x 6 = 120

Hence, the number representing the 6th grader participated in the field event is 120
