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:

r = \frac{f(b) - f(a)}{b - a}

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:

r = \frac{h(5) - h(2)}{5 - 2} = \frac{(2*5^2 - 7*5) - ( 2*2^2 - 7*2)}{3}  = \frac{15 - (-6)}{3}  = \frac{21}{3}  = 7

The average rate of change of h(x) in the given interval is 7.

max2010maxim [7]

Answer: Context

I get how Nikolai is working at home and will be getting paid $20 but despite the $25 being at a factory and is repetitive, here is a little word from experience. The $25 is a start-off which is pretty good and it won't always be at a factory. If Nikolai is working hard and repetitive, he will be promoted to the fact where he will be paid more and work at home time-to-time. The $20 one, however, is a work-at-home type and since there is children, the house will have to be quiet during calls and what-not.

We see this same problem pop up here on Brainly every
couple of months.  Nobody yet has ever given us enough
information to answer it. 

There's no information here that we can use to find out the
weight of any of the cattle placed on feed.  There must be
some more information BEFORE this. 

Maybe it's in the previous question in the book or on the
homework sheet, and nobody who posts this question ever
includes the information from the question before it.
