For this case we can make use of the following rule of three:
42 -----------------------> 21%
x -------------------------> 100%
In this case we have the following variable
x: unknown number whose 21% is equal to 42-
From the rule of three we clear x.
We have then:
Answer:
42 is 21% of 200
If x represents time, the average rate of change of the function f(x) in the first three seconds is ___.
Answer for Blank 1:
Answer:
-50
Step-by-step explanation:
The rate of change formula = f(b) - f(a) / b - a
f(b) = the end number (so basically 0 becuase the line ends on the point (3, 0))
f(a) = the start number (so basically 150 becuase the line starts on the point (0, 150)
b = the end time (so basically 3 becuase the line ends on the point (3, 0))
a = the start time (so basically 0 becuase the line starts on the point (0, 150)

sorry if that is confusing... moving on...

You would apply these numbers = 0 - 150 / 3 - 0 = -150 / 3 = -50
--
This is your rate of change

I hope this helped :)
