Let f(x)=x^2−3x−4 . What is the average rate of change from x = 7 to x = 10?

1 answer:

6 0

So, this is the answers you get from plugging in x = (7 through 10)
x = 7 ... 24
x = 8 ... 36
x = 9 ... 50
x = 10 ... 66

Then you get the rate of changes...

66 - 50 = 16
50 - 36 = 14
36 - 24 = 12

So the average of 16, 14 and 12 (those values added together and then that total divided by the number of values, which is 3) is 14

The average rate of change is 14

A machine can stamp 40 envelopes in 8 minutes. How many of these machines, working simultaneously, are required or needed to sta

ziro4ka [17]

Divide 40 by 8 minutes to find the quantity per minute for one machine:

40 / 8 = 5 per minute.

One machine does 5 envelopes per minute.

Now divide 120 by 5 to find the number of machines needed:

120 / 5 = 24

24 machines would be needed.
