A cylindrical cookie jar has a volume of 904.23 cubic inches. It is 8 inches tall. What is the radius of the cookie jar? Round your answer to the nearest inch.​

Answers

Answer:

Answer:

r = 6 in

Step-by-step explanation:

The volume of a cylinder of radius r and height or length h is

V = πr²h.

Here, we need to solve for the radius; we get:

     V

------------- = r²

     πh

                                       904.23 in³

This works out to    r² = ----------------- = 35.97 in²

                                            π(8 in)

Finally, take the square root of this result to find the radius, r:

r = √35.97 in² = 6 inches

Therefore the third side is "too small" to be the hypotenuse, making the triangle acute. You agree or disagree with jimmy? Explain and justify your answer.

This is a 45-45 traingle which mean that the two sides that aren't the hyptonouse are equal (because their angles are equal)

We will let x equal the length of one of the sides

we have

x²+x²=(4√2)²

2x²=32

x²=16

x=4

this means that the length of the two missing sides are 4

Now using the area of a traingle formula we can solve for the area

Answers

Answer:

The equations for each function:

A(t) = 60 - 6tB(t) = 42 - 3t

The lines plotted, see attached

The point at which both the snowmen have same height:

Given the function y = -5x + 4, what is the range of the function if the domain is {-2, 0, 5}?

Answers

Answer:

90 hours

Step-by-step explanation:

{14, 4, -21}  is the range of the function if the domain is {-2, 0, 5}

What is the function?

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

To find the range of the function, we need to plug each value in the domain into the given function and see what output (y-value) we get.

When x = -2:

y = -5(-2) + 4 = 14

When x = 0:

y = -5(0) + 4 = 4

When x = 5:

y = -5(5) + 4 = -21

So the range of the function is {14, 4, -21}.

Given are the first three terms of a sequence that is either arithmetic or geometric. If the sequence is arithmetic, find a1 and d. If a sequence is geometric, find a1 and r. 1/6,1/12,1/24

Answers

Answer:

a1 = 1/6

r = 1/2

Step-by-step explanation:

Given the sequence

1/6,1/12,1/24

The sequence is a geometric sequence since they have a common ratio

r = 1/12÷1/6 = 1/24 ÷ 1/12

r = 1/12 * 6/1 = 1/24 * 12/1

r = 1/2

Since a1 is the first term, hence a1 is 1/6 and common ratio r is 1/2

Suppose c(x) = x3 - 24x2 + 30,000x is the cost of manufacturing x items. Find a production level that will minimize the average cost per item of making x items.

Answers

Answer:

hence the required minimum production level is 12units

Step-by-step explanation:

Given the cost function expressed as c(x) = x^3 - 24x^2 + 30,000x

The average cost function will be c(x)/x

Dividing the cost function through by x

Average cost function = c(x)/x = x³/x - 24x²/x + 30,000x/x

Average cost function = x²-24x + 30,000

A(x) = x²-24x + 30,000

If the average cost is minimized, hence dA/dx = 0

dA/dx = 2x - 24

0 = 2x - 24

-2x = -24

Divide both sides by -2

-2x/-2 = -24/-2

x = 12

For the second deriviative

d²A/dx² = 2 which is greater than zero

Hence a production level that will minimize the average cost per item of making x items is 12

The production level that will minimize the average cost per item of making x items is  x = 12

How to obtain the minimum value of a function?

To find the minimum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.

Putting those values of x in the second rate of function, if results in negative output, then at that point, there is maxima. If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.

For this case, the function in consideration is: [tex]c(x) = x^3 - 24x^2 + 30000x[/tex]

This is cost function for x items' manufacturing.

The average cost per item would be c(x) / x

This gives us a function a(x) as:

[tex]a(x) = c(x)/x = x^2 -24x + 30000[/tex]

For finding  the minimum of a(x), getting its first two derivatives as:

[tex]a'(x) = 2x - 24\\a''(x) = 2 > 0[/tex]

Equating first rate to 0,

[tex]a'(x) = 2x - 24 = 0[/tex] critical point.

Since second rate is positive, the point x = 12 is point of minima, and since only one critical point is there, it is the point on which a(x) is minimum.

Thus, the production level that will minimize the average cost per item of making x items is  x = 12
