The volume of the cylinder in cubic centimeters is 251.2 cm^3.

The volume of a cylinder is expressed as:

V = πr²h

V = base area * height

Given the following

Base area =  16π centimeters

Height = 5cm

Substitute into the formula to have:

V = 16(3.14) * 5

V = 251.2 cm^3

Hence the volume of the cylinder in cubic centimeters is 251.2 cm^3.

Step 1: Define

m/2

m = -8

Step 2: Evaluate

Answer: -4

Step-by-step explanation: It's important to understand that m/2 means

the same thing as m ÷ 2.

In this case, we are given that m = -8.

So we have -8 ÷ 2 which is -4.

Remember that when you divide a negative number

The surface area of the spherical water tower is  2462 ft²

The surface area of the sphere is the portion he will paint.

Therefore,

surface area of a sphere = 4πr²

where

Therefore,

diameter = 2r

r = diameter / 2

surface area of a sphere = 4 × π × 14²

surface area of a sphere =  4 × π × 196

surface area of a sphere = 784π

surface area of a sphere = 784 × 3.14

surface area of a sphere = 2461.76

Answer:

I don't know the answer but try using 900gle lens and scanning it on homework setting

Answer:

Range is 0 ≤  h ≤ 32

Step-by-step explanation:

The height is a function of time and is described as h(t) = -8t² + 32t

h is the y-axis and t is the x axis, so we can write this as y = -8x² + 32 x.

This describes a parabola that opens downward, since the coefficient of the square term is negative. The maximum point for height will be at the vertex of the parabola.

y = ax² + bx + c

The x coordinate of the vertex is at -b/2a

a = -8, b = 32, c = 0

-b/2a = -32/-16 = 2

Maximum height is at x = 2 seconds (we can see this on the graph)

At 2 seconds, y = -8(2²) + 32(2) = -32 + 64 = 32

Again, we can see this on the graph.

The x intercepts are the points where y = 0

0 = -8x² + 32x = 8x(-x +4)

y will be 0 when x is 0 or 4 (confirmed by graph)

So, the height (y) = 0 at time (x) = 0 sec, 4 sec

0 ≤ y ≤ 32

y = h, so 0 ≤ h ≤ 32

I hope this helps.

Look at the line carefully. You can see that the line crosses the point (0,2). See it? The value of 2 in the point (0,2) is the y-intercept.

The given equations are all in the form

y = mx + b, where b is the y-intercept.

So, based on this data, we conclude that the line represents the equation y = (1/3)x + 2.

Answer:

(5a + 6b)(6[tex]a^{2}[/tex] + 5[tex]b^{2}[/tex])

Step-by-step explanation:

1. Factor out common terms in the first two terms, then in the last two terms

2.  Factor out the common term 5a + 6b

Answer:

20

Step-by-step explanation:

To evaluate, substitute x = 6 into f(x) , that is

f(6) = 2(6) + 8 = 12 + 8 = 20

[tex]f(x)=2x+8[/tex]

Substitute x = 6 in the equation.

[tex]f(6)=2(6)+8\\f(6)=12+8\\f(6)=20[/tex]

Therefore, the answer is f(6) = 20.

The last choice.

Answer:

-.82

Step-by-step explanation:

To find the average rate of change over an interval, you use rise over run with the first point and the last point (in this case, the first point is (50, 35.8) and the last point is (60, 27.6)). This will give you an average rate of change of -.82.

In the context of this problem, -.82 is how much your expected remaining life span decreases each year.

The number of dimes Joe has is 6.

Joe has dimes and nickels, the total amount is $1.45

We have to find the number of dimes Joe has.

Suppose the number of dimes is d, so we have the number of nickels is 2d + 5

Now from the question, we get an equation:

0.10d + 0.05( 2d+ 5) = $1.45

To know the value of d we need to solve the equation:

0.10d + 0.10d + 0.25 = 1.45

0.20d = 1.20

d = 120/20

   = 6

Hence we get the total number of dimes Joe has is 6.

Answer:

D: -75 the balloon is descending at a rate of 75ft per minute

Step-by-step explanation:

To find the slope of any graph, take two points on the graph and subtract them y/x so to get this answer is used the points (0,450) and (2,300) and subtracted the y-values over the x-values

450-300=150

0-2=-2

150/-2 = -75

that is the slope and since it is negative and the slope itself is a diagonal line going towards the x-axis you know it’s descending.

Answer:

The Equation we can use to solve for the cost of each box of candy =

4.95 + 3b = 18.45

The cost of each box of candy = $4.5

Step-by-step explanation:

Let the number of boxes of candy be represented by: b

Each box of candy cost the same amount

Hence from the question above, we have the Equation:

$4.95 + 3b = $18.45

4.95 + 3b = 18.45

3b = 18.45 - 4.95

3b = 13.5

b = 13.5/3

b = 4.5

The cost of each box of candy = $4.5

The equation of sets is given by n(A∪B) = n(A) + n(B) - n(A⋂B)

What is Set Theory Formula?

The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.

Given data ,

Let the equation be represented as A

The value of A is

n(A∪B) = n(A) + n(B) - n(A⋂B)

So , from the given Venn diagram , we get

The number of people who have been to the United States and Australia is given by A = 2

Step-by-step explanation:

Answer:

The pipe lengths are 50 inches and 100 inches.

Step-by-step explanation:

If we refer to the length of the shorter piece as x, then we can say the length of the larger piece is 2x.  We are also told that the pipe length is 150 inches, so we can say:

x + 2x = 150

3x = 150

x = 150/3

x = 50

So the pipe lengths are 50 and 100 inches respectively.
