Answer: 314

Step-by-step explanation: This is true because 2512 by 8 you get 314

The radius of a pool is 10 feet.

It is required to find the radius of a pool.

Cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. A cylinder has two bases and a curved surface. Total surface area = 2πr(r +h) square units. Curved surface area = 2πr h square units.

Given:

The given pool is in the shape of cylinder.

Volume of a pool = 2512 cubic feet

The height = 8 feet.

According to given question we have,

Volume of a pool=π[tex]r^{2} h[/tex]

2512 =π[tex]r^{2} *8[/tex]

Divide 8 on both sides we get,

[tex]r^{2}[/tex]=314/π

[tex]r=\sqrt{314/3.14} \\\\r=10 feet[/tex]

Therefore, the radius of a pool is 10 feet.

Answer:

I found thois from someone else asking this queetion so gope it helps.

Step-by-step explanation:

I'm sure you want your functions to appear as perfectly formed as possible so that others can help you.  f(x) = 4(2)x should be written with the " ^ " sign to denote exponentation:  f(x) = 4(2)^x

                                                                                     f(b) - f(a)

The formula for "average rate of change" is a.r.c. = --------------

                                                                                          b - a

                                   change in function value

This is equivalent to  ---------------------------------------

                                           change in x value

For Section A:  x changes from 1 to 2 and the function changes from 4(2)^1 to  4(2)^2:  8 to 16.  Thus, "change in function value" is 8 for a 1-unit change in x from 1 to 2.  Thus, in this Section, the a.r.c. is:

                8

              ------ = 8 units    (Section A)

                 1

Section B:  x changes from 3 to 4, a net change of 1 unit:  f(x) changes from

4(2)^3 to 4(2)^4, or 32 to 256, a net change of 224 units.  Thus, the a.r.c. is

       224 units

     ----------------- = 224 units (Section B)

           1 unit

The a.r.c for Section B is 28 times greater than the a.r.c. for Section A.

This change in outcome is so great because the function f(x) is an exponential function; as x increases in unit steps, the function increases much faster (we say "exponentially").

Step-by-step explanation:

Replace x with 1, because x = 1:

(1) [(1) - 3] + 2

[1 - 3] + 2

[-2] + 2

0

The description that matches the inequality x < 1 is:

All the points to the left of x = 1 are part of the solution, and there is an open interval at x = 1.

The values that are less than a number a in the number line are the values to the left of a.

Hence, for the inequality x < 1, we have that:

All the points to the left of x = 1 are part of the solution

Additionally, since the inequality signal is < and not ≤ 1, x = 1 is not part of the inequality, meaning that there is an open interval at x = 1.

Answer:

Area of whole circle, i.e. 360 degrees = π(8.91)(8.91) = 79.3881 sq. cm

Area of 1 degree = 0.2205225 sq.cm.

Area of 81 degrees = 17.8623225 sq.cm.

The area of the shaded sector is about 16.77 cm2.

We are given that;

The radius=8.91

Now,

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

To find the area of the shaded sector, we need to use the formula:

[tex]$A = \frac{\theta}{360} \times \pi r^2$[/tex]

where [tex]\theta[/tex] is the central angle in degrees, and r is the radius of the circle.

Plugging in the given values, we get:

[tex]$A = \frac{81}{360} \times \pi (8.91)^2A \approx 16.77 \text{ cm}^2$[/tex]

Therefore, by the area answer will be 16.77 cm2.

Answer: 5 2/5

Step-by-step explanation: Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Lastly, you should end up with an answer.

The answer is 5 11/12.

You have to add 3 1/4 AND 2 2/3.

3 1/4 + 2 2/3 =

add the whole numbers FIRST.

2 + 3 = 5

Now add the fractions

1/4 + 2/3 = 11/12.

Now add both of the numbers

Answer:

-2.797

Step-by-sep explanation:

The area in the left tail is the level of significance = [tex] \alpha = 0.005 [/tex]

n = 25

Since sample size, n, = 25,

Degree of freedom = n - 1 = 25 - 1 = 24

The value of t for the t distribution, that is the t critical value, would be:

[tex] -t\binom{n - 1}{\alpha} = -t\binom{9}{0.005} [/tex]

The t critical value can be gotten from the t-table at the intersection of the row representing 24 degrees of freedom and the [tex] t_{0.005} [/tex] column. This would give us -2.797

The t critical value of the left tail would be critical value is -2.797.
