<h3>
Answer: 15 kg</h3>
==============================================
Work Shown:
KE = 480
v = 8
KE = (1/2)*m*v^2
480 = 0.5*m*8^2
480 = 0.5*m*64
480 = 0.5*64m
480 = 32m
32m = 480
m = 480/32
m = 15
The SI unit for mass is in kilograms
Also a joule is defined with kilograms since 1 J = 1 kg*m/s^2
1 joule is the amount of energy needed to move an object of mass 1 kg with an acceleration of 1 m/s^2
So this is why the mass m is in kilograms.
Answer:
$1100. She would be paid $1100 monthly.
Step-by-step explanation:
Well first off. She gets paid WEEKLY at $275.
If she was paid MONTHLY we need to multiply $275 by the amount of weeks in a month.
Typically there are 4 weeks to a month so we would do 4 * $275.
4*$275=$1100

The average rate of change of the function over the given interval is 9
Here, we want to calculate the average rate of change of the function within the given interval
Mathematically, given a function f(x) , the average rate of change of the function within the interval a ≤ x ≤ b is given below;
![\frac{f(b)\text{ - f(a)}}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29%5Ctext%7B%20-%20f%28a%29%7D%7D%7Bb-a%7D)
withe respect to this question;
a = 1
b = 4
f(a) = f(1) = 12
f(b) = f(4) = 39
The average rate of change within the given interval is thus;
The answer will be a(8b + 7c)
