Answer:
It is: (f(2) - f(0))/(2 - 0)
f(2) = 250(0.5)(2) = 250
f(0) = 250 (0.5)(0) = 0
So: (250 - 0)/(2 - 0) = 250/2 = 175
The average rate of change is 175.

Answer:
without numbers= 10x + 15y = 120
Step-by-step explanation:
grocery store= 10x (x=8 in this case)
music lessons= 15y
Answer:
33.5
Step-by-step explanation:
To solve, you will use the formula 4/3 of pi times radius cubed.
The formula that we want to use here is S = D/T.
S = Speed
D = Distance
T = Time
So, we know that S = 550 and T = 3.5, so we can plug them in.
We get 550 = D/3.5
Multiply by 3.5 on each side, and you figure out that the plane has traveled 1925 miles.
√19 = 4.36
√77 = 8.77
So integers between √19 and √77 are 5, 6, 7 and 8. And their sum is
5 + 6 + 7 +8 = <u>26</u>
