Answer:
The average rate of change of h(x) in the given interval is 7.
Step-by-step explanation:
When we want to find the average rate of change of a function f(x), in an interval a < x < b, we just need to calculate:
Here we have:
h(x) = 2*x^2 - 7*x
And we want to find the average rate of change between x = 2 and x = 5
This will be:
The average rate of change of h(x) in the given interval is 7.

Answer:
20 hits
Step-by-step explanation:
Multiply the batting average by the number of times at bat
.444*45 = 19.98
She will get about 20 hits
Let:
• y, be the cost of the plan
,
• x, be the minutes spend on call
This way, we'll have:
Plan A:
Plan B:
If the two plans cost the same, we'll have that:
Solving for x :
A) The two plans will cost the same for 140 minutes on call
The cost will be:
B) $36.80
B x b x b x b x b x b x b x b x b x b x b x b x b x b x b
