Answer:
Average rate of change =
Step-by-step explanation:
Average rate of change of a function 'f' in the interval a ≤ x ≤ b is given by,
Average rate of change =
We have to find the average rate of change in the interval 20 ≤ x ≤ 65
From the table attached,
f(65) = 32
f(20) = 14
Average rate of change =
=
=
Therefore, average rate of change in the given interval is .
Given:
Consider the below figure attached with this equation.
To find:
Length of side ZX.
Solution:
From the figure it is clear that, WXY is a right angled triangle.
According the 30°-60°-90° theorem, the longer leg (opposite to 60° angle) of the right-angled triangle is times of shorter leg (opposite to 30° angle).
In the below figure, WY is longer leg and XY is shorter leg.
So, the length of XY is 8 units.
VWYZ is a rectangle, so
Now,
So, the length of ZX is 18 units.
Therefore, the correct option is C.
