(time limit!) what is the volume below? A) 112 B) 224 C) 784 D) 896

Radda [10]

To find a volume of a cylinder we use the following formula:
$v = \pi {r}^{2} h$
Plug in the values:

$v = \pi \times {8}^{2} \times 14$
Take the square:
$v = \pi \times 64 \times 14$
Multiply the numbers:
$v =896 \pi {m}^{2}$

Greetings!

We can factor this expression/ the GCF is:
$-10m^2n^7$

$(-10m^2n^7)(5m^2-4n^3)$

Hope this helps.

Marina earns $15 for 1 hour of babysitting $23 for 2 hours of babysitting and $31 for 3 hours of babysitting. Write a function t

DochEvi [55]

Answer:

Step-by-step explanation:

Let y represent the amount that Marina earns for babysitting.

Let x represent the number of hours of babysitting.

If we plot the graph of y on the vertical axis and x on the horizontal axis of a graph,

the slope which is expressed as

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

Slope = (23 - 15)/(2 - 1) = 8

We would model the function in the slope intercept form which is expressed as

y = mx + c

Where c represents the intercept.

To determine c, we would substitute y = 15, x = 1 and m = 8 into y =mx + c. It becomes

15 = 8 × 1 + c

15 = 8 + c

c = 15 - 8 = 7

The function that describes the sequence would be

y = 8x + 7
