What is volume of a prism?

A prism is a solid shape that is bound on all its sides by plane faces.

The volume of a prism is expressed as;

volume = base × height

The volume of the tank = 5×7×9

= 315 in³

The volume of the sand is 375 .

Therefore the volume of the sand is greater than that of the tank, this means the sand will not fit into the tank.

B. The height of the second tank = 9+2 = 11

The volume of the second tank = 5×7 × 11 = 385

therefore the difference in the volume of the first and second tank = 385-315

= 70in³

C. If the tank has thesame base, then the height will be

375 = 5× 7 × h

375 = 35h

h = 375/35

h = 10.7 in

therefore the measurement of the tank that will hold exactly 375 is 5in × 7in × 10.7 in

Realiza las siguientes transformaciones de coordenadas polares a rectangulares o de coordenada rectangular a polar e identifica el cuadrante al que pertenecen

Answers

The polar coordinates corresponding to the rectangular coordinates (0, 5) are (5, π/2).

To find the distance from the origin to the point (r), we can use the Pythagorean theorem. The distance from the origin to a point (x, y) is given by the formula √(x² + y²).

In this case, since the x-coordinate is 0, we only need to find the distance from the origin to the y-coordinate. Therefore, r = √(0² + 5²) = 5.

To find the angle (θ) that the line from the origin to the point makes with the positive x-axis, we can use trigonometry.

However, this is undefined since we cannot divide by zero. Therefore, we need to use a special case. Since the x-coordinate is 0, the point lies on the y-axis.

Therefore, the angle θ is either π/2 or 3π/2. However, we are given the constraint 0 ≤ θ < 2π. Therefore, the angle θ = π/2 since it satisfies the constraint.

Find the measure of angle E.

Answers

Answer:

m∠E = 57º

Step-by-step explanation:

We can use the isosceles triangle theorem to determine that angle E is congruent to angle D, since side DF is congruent to side EF.

This means that:

m∠E = m∠D

m∠E = (4x + 1)º

Now, we can solve for x using the fact that the interior angles of a triangle sum to 180º.

m∠D + m∠E + m∠F = 180º

↓ substituting the given angles measures (in terms of x)

(4x + 1)º + (4x + 1)º + (5x - 4)º = 180º

↓ grouping like terms

(4x + 4x + 5x)º + (1 + 1 - 4)º = 180º

↓ combining like terms

13xº - 2º = 180º

↓ adding 2º to both sides

13xº = 182º

↓ dividing both sides by 13º

x = 14

With this x value, we can now solve for m∠E using its definition in terms of x.

m∠E = (4x + 1)º

↓ plugging in solved x value

m∠E = (4(14) + 1)º

m∠E = (56 + 1)º

m∠E = 57º

What is an exponents?

In mathematics, exponents are a way to indicate the repeated multiplication of a number or phrase.

Exponents are numbers that are superscripted above other numbers. In other words, it denotes that a certain level of power has been conferred upon the base. Index and power are other names for the exponent. If m is a positive number and n is its exponent, the expression Mn means that m has been multiplied by itself n times.

Exponents are required for a more comprehensible representation of numerical quantities. Repeated multiplication is simple to write down when using exponents. If both n and x are positive integers, the expression xn means that x has been multiplied by itself n times.

When multiplying two numbers with the same base, we can add their exponents. Therefore:

[tex]10^{32} \times 10^{36 }= 10^{(32+36) }= 10^{68}[/tex]

Hence, [tex]10^{32} \times 10^{36}[/tex]can be written as [tex]10^{68}[/tex] using a single exponent.

Find all zeros (real and complex ) of the polynomial x^(4)+2x^(3)+22x^(2)+50x-75=0

Answers

The zeros of the polynomial x4 + 2x3 + 22x2 + 50x - 75 = 0 are x = 3, x = -5, x = ±√(37).


To find all the zeros (real and complex) of the polynomial x^(4)+2x^(3)+22x^(2)+50x-75=0, we can use the Rational Root Theorem and synthetic division.

The Rational Root Theorem states that if p/q is a rational root of a polynomial equation, then p must be a factor of the constant term and q must be a factor of the leading coefficient.

The factors of the constant term -75 are: ±1, ±3, ±5, ±15, ±25, ±75
The factors of the leading coefficient 1 are: ±1

Therefore, the possible rational roots of the polynomial are: ±1, ±3, ±5, ±15, ±25, ±75

We can use synthetic division to test each of these possible roots until we find one that is a root. Once we find a root, we can use synthetic division again to divide the polynomial by the factor (x - root) to get a smaller polynomial, and then repeat the process until we have found all the roots.

Using synthetic division, we find that 3 is a root of the polynomial. Dividing the polynomial by (x - 3) gives us a smaller polynomial: x^(3)+5x^(2)+37x+25=0

We can repeat the process with this smaller polynomial to find the remaining roots. Using synthetic division again, we find that -5 is a root of the smaller polynomial. Dividing the smaller polynomial by (x + 5) gives us an even smaller polynomial: x^(2)+37=0

This polynomial has no real roots, but it has two complex roots: x = ±√(-37) = ±√(37)i

So, the complete list of zeros (real and complex) of the original polynomial is: 3, -5, ±√(37).

4) ƒ(x) = −x³ + 4x² − 2

Answers

These are the x-coordinates of the points where the graph intersects the x-axis. We can use these points to sketch the curve of the function.

What is equation?

An equation is a mathematical statement that indicates the equality of two expressions. It consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is equivalent to the expression on the right side. Equations can have one or more variables, which are usually represented by letters such as x, y, or z. The goal in solving an equation is to determine the value(s) of the variable(s) that make the equation true. This involves manipulating the expressions on both sides of the equal sign using algebraic operations such as addition, subtraction, multiplication, and division, to isolate the variable on one side of the equation. Equations are used in many areas of mathematics and science to represent relationships between variables and to solve problems. They are also used in various fields such as engineering, physics, and economics to model real-world situations and make predictions based on mathematical analysis.

Here,

The function ƒ(x) = −x³ + 4x² − 2 is a cubic function, which means that it is a polynomial of degree 3. The general form of a cubic function is:

ƒ(x) = ax³ + bx² + cx + d

where a, b, c, and d are constants. In the given function, we have:

a = -1

b = 4

c = 0

d = -2

Therefore, we can rewrite the function as:

ƒ(x) = -x³ + 4x² - 2

This function can be graphed to show the shape of the curve it creates. The graph of a cubic function is a curve that can either be concave up or concave down, depending on the sign of the leading coefficient. In this case, the leading coefficient is negative, so the graph will be concave down. The function has a y-intercept of -2, which means that it intersects the y-axis at the point (0, -2). To find the x-intercepts, we can set ƒ(x) equal to zero and solve for x:

ƒ(x) = -x³ + 4x² - 2 = 0

We can use factoring or the quadratic formula to solve for x, but in this case, the equation can be simplified by factoring out a common factor of x²:

-x²(x - 4) + 2 = 0

Now we can solve for x:

x² = 2/(4 - x)

Answers

Answer: f(g(2)) = 1   and g(f(1)) = 2

Step-by-step explanation:

The equation of the parabola is f(x) = x² - 4x + 4

The equation of the line is g(x) = x + 1

To find f(g(2)), you must first find g(2)

g(2) = (2) + 1

g(2) = 3

Now find f(g(2)) by using 3 for g(2)

f(3) = (3)² - 4(3) + 4

f(3) = 9 - 12 + 4

f(3) = 1

f(g(2)) = 1

To find g(f(1)), you must first find f(1)

f(1) = (1)² - 4(1) + 4

f(1) = 1 - 4 + 4

f(1) = 1

Now find g(f(1)) by using 1 for f(1)

g(1) = (1) + 1

g(1) = 2

g(f(1)) = 2

Answers

Using the unit tile the area of the three diagrams is - square tile = 1 unit², rectangular tile = x unit², and square tile = x² unit².

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

For the square tile with length and breadth = 1 unit, the area is simply the product of the length and breadth, which is 1 unit × 1 unit = 1 unit².

This is the same as the area of the unit tile, so we don't really need to use it to find the area of this tile.

For the rectangular tile with length = x units and breadth = 1 unit, we can use x unit tiles to cover the length, and 1 unit tiles to cover the breadth.

Therefore, the area of the rectangular tile is x unit × 1 unit = x unit².

For the square tile with length and breadth = x units, we can use x unit tiles to cover the length, and x unit tiles to cover the breadth.

Therefore, the area of the square tile is x unit × x unit = x² unit².

In general, for any tile with length = a units and breadth = b units, the area is given by the product of the length and breadth, which is a unit × b unit = ab unit².

Therefore, we can use the unit tile to find the exact area of any tile, as long as we know its dimensions.

Graph the equation y=2/3x -1

Answer:

Step-by-step explanation:

sider the given function n(x)=x^(2)+10x+24 Write the function in vertex form. Identify the vertex. Determine the x-intercept (s). Determine the y-intercept (s).

Answers

The given function, n(x)=x^(2)+10x+24, can be written in vertex form by completing the square. Vertex form is given by y=a(x-h)^2+k.

The vertex is at (h,k). To find h and k, first find the average of the x-values of the two roots:

h = ( -b +- sqrt(b^2 - 4ac) ) / 2a
 = ( -10 +- sqrt( 10^2 - 4(1)(24) ) ) / 2(1)
 = ( -10 +- sqrt(100 - 96) ) / 2
 = ( -10 +- sqrt(4) ) / 2
 = ( -10 +- 2 ) / 2
 = -6

Substituting h into the equation y=a(x-h)^2+k, we have:

k = y - a(x-h)^2
 = n(x) - a(x+6)^2
 = x^2 + 10x + 24 - a(x+6)^2
 = 24 - a(x+6)^2

We know that when x=-6, k=24, so

24 = a( -6+6 )^2
24 = 36a
a = 2/3

Therefore, the equation in vertex form is y = 2/3(x+6)^2 + 24.

The vertex is (h,k) = (-6, 24).

The x-intercepts (s) are the roots of the equation, so they can be found by setting the equation equal to 0 and solving for x.

0 = x^2 + 10x + 24
0 = (x+6)(x+4)

Therefore, the x-intercepts are x=-6 and x=-4.

The y-intercept is when x=0, so it is y = 24.

Answers

The number of adults is 120, and the total money made from ticket sales is £1120.

How is a ratio utilised in mathematics? What is it?

The mathematical connection between two or more numbers is called a ratio, and it is represented as the product of the division of two values. Several formats, such as fractions, decimals, or percentages, can be used to express ratios. Mathematicians employ ratios in many different areas, including geometry, probability, and finance. The connection between the lengths of two or more sides of a form is described in geometry using ratios. Ratios, sometimes in the form of odds, are used in probability to indicate the possibility of an event occurring.

Let x be the number of adults.

Given that, ratio of children to adults is 2 : 3.

Thus,

2/3 = 80/x

Cross-multiplying gives:

2x = 240

x = 120

The number of adults is 120.

Each child ticket costs a quarter of the adult ticket, so the cost of a child ticket is:

1/4 * £8 = £2

The total money made from child tickets is:

£2 * 80 = £160

The total money made from adult tickets is:

£8 * 120 = £960

Total money made from ticket sales is:

£160 + £960 = £1120

A 6-foot person standing 18 feet from a streetlight casts a 10-foot shadow. Two similar triangles are formed. One triangle is formed by the person and the shadow that the person casts. A second triangle is formed by the streetlight and the ground from the base of the streetlight to the end of the shadow.

Answers

The streetlight is approximately 16.41 feet tall, and the length of its shadow is approximately 27.35 feet.

What is the proportion?

A proportion is a statement that two ratios are equal. In other words, a proportion is an equation that shows that two fractions or two ratios are equivalent. A proportion can be written in the form of:

a/b = c/d

We can use the properties of similar triangles to solve this problem. Let's call the height of the streetlight h, and the length of the shadow cast by the streetlight x. We can set up the following proportion:

(height of person) / (length of person's shadow) = (height of streetlight) / (length of streetlight's shadow)

or

6 / 10 = h / x

Simplifying this proportion, we get:

x = (10h) / 6

We also know that the person is standing 18 feet from the streetlight, and that the length of the person's shadow is 10 feet. Using the Pythagorean theorem, we can set up the following equation:

6^2 + 10^2 = (18 + x)^2

Simplifying and substituting x, we get:

36 + 100 = (18 + (10h/6))^2

136 = (18 + (10h/6))^2

Taking the square root of both sides, we get:

√136 = 18 + (10h/6)

Simplifying, we get:

√136 - 18 = (10h/6)

Multiplying both sides by 6, we get:

6(√136 - 18) = 10h

Simplifying, we get:

h ≈ 16.41 feet

Now, we can substitute this value of h into the expression for x that we derived earlier:

x = (10h) / 6 ≈ 27.35 feet

Therefore, the streetlight is approximately 16.41 feet tall, and the length of its shadow is approximately 27.35 feet.

5. Three similar steel bars of lengths 210 cm, 300 cm, 360 cm are cut into equal parts. Find
the smallest possible area of a square which can be made from the three pieces

Answers

The smallest possible area of a square which can be made from the three pieces is 11833.203125 cm².

What is the smallest possible area?

To find the smallest possible area of a square, we need to make sure that we use the longest pieces to form the sides of the square. Therefore, we need to divide the 360 cm steel bar into equal parts first, then use the remaining parts to divide the other two steel bars.

Let's call the length of each part x.

The 360 cm steel bar can be divided into n parts of length x, where:

n = 360/x

Similarly, the 300 cm steel bar can be divided into m parts of length x, where:

m = 300/x

And the 210 cm steel bar can be divided into k parts of length x, where:

k = 210/x

To form a square, we need to use all the parts we cut from the steel bars. Therefore, the length of the sides of the square will be nx + mx + kx, which is equal to (n + m + k)x.

The area of the square will be (n + m + k)x²

To find the smallest possible area, we need to minimize (n + m + k)x². Since x can be any positive number, we can focus on minimizing n + m + k.

n + m + k = (360/x) + (300/x) + (210/x)

n + m + k = (870/x)

To minimize (n + m + k), we need to maximize x. However, x cannot be greater than the smallest steel bar, which is 210 cm long.

Therefore, x must be a factor of 210.

Let's try x = 1 cm. In this case, n + m + k = 870 cm, which means we can form a square with sides of length 870 cm/4 = 217.5 cm.

The area of this square is 217.5^2 = 47250.625 cm².

Let's try x = 2 cm. In this case, n + m + k = 435 cm, which means we can form a square with sides of length 435 cm/4 = 108.75 cm.

The area of this square is 108.75² = 11833.203125 cm².

Let's try x = 3 cm. In this case, n + m + k = 290 cm, which means we cannot form a square using all the parts we cut from the steel bars.

Therefore, the smallest possible area of a square which can be made from the three pieces is 11833.203125 cm², and this can be achieved by cutting the steel bars into parts of length 2 cm.

coefficients. asses through (-3,2) and is parallel to the line defined by 5x+2y=-10

Answers

To find the equation of the line that passes through (-3,2) and is parallel to the line defined by 5x+2y=-10, we need to follow these steps:

Step 1: Find the slope of the given line. Since the equation is in the form of Ax + By = C, we can rearrange it to the slope-intercept form, y = mx + b, where m is the slope.
5x + 2y = -10
2y = -5x - 10
y = (-5/2)x - 5
So, the slope of the given line is -5/2.

Step 2: Since the two lines are parallel, they have the same slope. So, the slope of the new line is also -5/2.

Step 3: Use the point-slope form of a line to find the equation of the new line. The point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point.
y - 2 = (-5/2)(x - (-3))
y - 2 = (-5/2)x - 15/2
y = (-5/2)x - 15/2 + 2
y = (-5/2)x - 11/2
So, the equation of the new line is y = (-5/2)x - 11/2.

Therefore, the equation of the line that passes through (-3,2) and is parallel to the line defined by 5x+2y=-10 is
y = (-5/2)x - 11/2.

what is the rule multiplying with same sign

Answers

Answer:

When you multiply two numbers with the same sign (either both positive or both negative), the rule is that the result is always positive.

For example, if you multiply +2 and +3, the result is +6 because both numbers have the same positive sign. Likewise, if you multiply -4 and -5, the result is +20 because both numbers have the same negative sign.

This rule applies to any two numbers with the same sign, regardless of their values or whether they are whole numbers, fractions, or decimals.

If a random variable X has exponential distribution with mean 1 then P[X > 2] is
a. 1- e^-2 b. e^2 c. e^-2
d. 1-e²

Answers

The correct answer is option a. 1 - e^-2.

To find the probability of a random variable X with exponential distribution, we use the following formula:P[X > x] = e^(-λx)Where λ is the rate parameter and x is the value we are trying to find the probability of.

In this case, we are given that the mean of the distribution is 1, so we can use this information to find the rate parameter:λ = 1/mean = 1/1 = 1Now, we can plug in the values for λ and x into the formula to find the probability:P[X > 2] = e^(-1*2) = e^-2 = 0.1353Therefore, the correct answer is option a. 1 - e^-2.

No matter what the value of s, √s^2 is equal to the value of s.

Answers

The statement that √s^2 is equals to the value of s is false, as s² is an even function, hence √s^2 can be equal either to the value of s or to -s.

What are even and odd functions?

In even functions, we have that the statement f(x) = f(-x) is true for all values of x.In odd functions, we have that the statement f(-x) = -f(x) is true for all values of x.If none of the above statements are true for all values of x, the function is neither even nor odd.

The s² function is even, hence, for example:

sqrt[(-3)²] = sqrt(9) = 3.
