Answer:
22.5
Step-by-step explanation:
The average rate of change on the interval [a, b] is the ratio ...
(f(b) -f(x))/(b -a)
For your function and interval, it is ...
(f(0.5) -f(0))/(0.5 -0)
Since f(0) = 0, this reduces to ...
average rate of change = 2·f(0.5) = 2(5(0.5)² +20(0.5)) = 2(5/4 +10)
average rate of change = 22.5
Answer:
The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210
Step-by-step explanation:
Let
x ---> the number of gift wrap rolls for solid colors sold
y ---> the number of gift wrap rolls for sprint patterns sold
we know that
---->
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
<em>Find the value of x</em>
---->
therefore
The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210
