### A ball has a diameter of 14 inches. Which choice is closest to its surface area? Use 3.14 to approximate pi.

So we know the formula to find the surface area of a sphere (ball) is:
4 x pi x r^2

to find the radius, divide the diameter by 2 to get:
14 / 2 = 7

now we substitute in the values:
4 x pi x 7^2

simplify:
4 x pi x 49

simplify:
12.56 x 49

simplify:
615.44 inches

### A sequence is defined recursively using the formula f(n + 1) = f(n) – 5 . Which sequence could be generated using this formula? *1, –5, 25, –125, ... *2, 10, 50, 250, ... *3, –2, –7, –12, ... *4, 9, 14, 19, ...

Option C. 3, -2, -7, -12....

Step-by-step explanation:

The sequence is defined recursively using the formula f(n+1) = f(n) - 5

We have to identify the sequence generated by this formula.

B). 1, -5, 25, -125.....

f(n+1) = -5 and f(n) = 1

Therefore - 5 = 1 - 5

⇒ -5 ≠ -4

This sequence is not following the formula.

B). 2, 10, 50, 250.........

f(n+1) = 10 and f(n) = 2

Now we use the formula

10 = 2 - 5

10 ≠ -3

This sequence is not following the formula.

C). 3, -2, -7, -12

f(n+1) = -2 and f(n) = 3

We put this value in the formula

-2 = 3 - 5

-2 = -2

Therefore , the sequence is following the formula.

D). 4, 9, 14, 19........

f(n+1) = 9 and f(n) = 4

9 = 4 - 5

9 ≠ -1

Therefore the formula is not applicable to form this sequence.

The cost of painting the house will be the same for both companies if the number of hours required to paint Paul’s house is? The most cost effective company will be:$75.00
25 hours

Painting USA: Fixed Cost: $75; Variable Cost:$25x
Total Cost = 75 + 25(25) = 75 + 625 = 700

Upscale Home Painting: Fixed Cost: $0; Variable Cost:$40x
Total Cost = 40(25) = 1,000

The most cost effective company will be Painting USA whose charges will amount to $700 The cost of painting the house will be the same for both companies if the number of hours required to paint Paul's house is: Painting USA: Total Cost: 75 + 25(25) = 75 + 625 = 700 Upscale Home Painting Total Cost: 40(16.5) = 40 + 660 = 700 The cost of painting the house will be the same for both companies if the number of hours required to paint Paul's house is approximately between 16.5 and 25 hours. just look the question it's there ANSWERED AT 22/01/2020 - 01:54 AM QUESTION POSTED AT 22/01/2020 - 01:54 AM ### Claudias regular shift is from 3pm to 8 pm.

### What is the first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k? 16 must be factored from 18x + 14 x must be factored from 6x2 + 18x 6 must be factored from 6x2 + 14 6 must be factored from 6x2 + 18x

A quadratic equation has the general form of:

y=ax² + bx + c

It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:

y = a(x+h)² - k

where h and k represents the vertex, h represent the point in the x axis and k is the point in the y axis. From the choices given, the first step in rewriting the equation is that
6 must be factored from 6x2 + 18x. Which yields to:

y = 6(x^2 + 3x) + 14
