Answer:
The ranger should walk <u>0.577 miles per hour</u> in order to decrease the time required to reach the car.
Step-by-step explanation:
Suppose the ranger reaches x miles from the end of the road which becomes the horizontal distance and the vertical distance is 1 miles. A right angle triangle can be obtained that shows the ranger walks along the hypothesis.
The distance left to reach the car is = 5 - x
To calculate total time taken, then the function becomes
In order to find the minimized time, differentiate the function T as follows
Equate the derivative to zero and obtained
Squaring both sides
The ranger should walk 0.577 miles per hour in order to decrease the time required to reach the car.

Answer:-16.8 / 14 = - 1.2 per day
Step-by-step explanation:
Given function is:In order to find the value of a function on a particular input, the variable in the function is replaced with the value.We have to find f(8), so putting 8 in place of xSo the value of function at 8 is 6 .
The y intercept of the left graph is 2 and the y intercept for the right graph is -0.5. These are the points where the line cross the y-axis (the vertical axis)
