Solve for R by simplifying both sides of the equation, the isolating the variable.
R^2h=-r^2+v
4x+5x = 90
9x = 90
x = 10
10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12

Answer:
The average rate of change between x = 2 and x = 4 is of 4.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function f(x) in an interval [a,b] is given by:

In this question:

Thus:


Average rate of change:




The average rate of change between x = 2 and x = 4 is of 4.
