To find the volume of water in the pool, we would find the area of the pool's surface and multiply it by the depth of the pool. The area of the pool's surface would be determined by the formula,

Area = pi x radius^2

From the information given,

diameter = 5

recall,

radius = diameter/2

Thus,

radius = 5/2 = 2.5

depth = 6 inches

We would convert from inches to feet

Recall,

12 inches = 1 foot

6 inches = 6/12 = 0.5 foot

Thus, depth = 0.5

pi = 3.14

Thus,

Area = 3.14 x 2.5^2 = 19.625

Volume = 19.625 x 0.5 = 9.8125

Volume of water in pool is 9.8 cubic feet to 1 decimal place

dimaraw [331]

Answer:

-22

Step-by-step explanation:

f(x) = 5x -7

substitute x = -3 into the equation as follows:

f(-3) = 5( -3) -7

= -15-7

= -22

Which recursive definition could be used to generate the sequence {3, 6, 3, 6, 3,...}?
PIT_PIT [208]

The recursive definition used to generate the sequence {3, 6, 3, 6, 3,...} is:

a_n = a_{n - 1} + 3(-1)^n where a_1 = 3 and n\geq 2

<em><u>Solution:</u></em>

Given sequence is 3, 6, 3, 6, 3,...

To find: recursive definition for the sequence

First term in the sequence is 3

Then you add on 3 to get to 6 as the second term

Then add -3 to get 3 as third term

This pattern goes on forever

3 + 3 = 6

6 - 3 = 3

3 + 3 = 6

6 - 3 = 3

and so on

<em><u>So we can generate a recursive definition as:</u></em>

Let a_n be the nth term and "n" denotes the term's location

a_1 is the first term of sequence

a_n = a_{n - 1} + 3(-1)^n , where a_1 = 3 and n\geq 2

Here, 3(-1)^n is used to denote , we add on either +3 or -3 to the previous term to get next term

the area of ava rectangular back yard is 325 square yards.if the length of the yards is 13 yards,what is the width of the yard
Viktor [21]

It is given in the question that, The area of ava rectangular back yard is 325 square yards and the length of the yards is 13 yards.

Let the width be w yard .

And area of rectangle is the product of length and width .

So we have

325 = 13 w

Dividing both sides by w

\frac{325}{13} = \frac{13w}{13} => w = 25 yards .

So the width is 25 yards .
