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:
Step-by-step explanation:
Time taken by Kara:
Time taken by Anna:
Part A
Kimberly runs faster because she runs at a pace of 5 miles per hour rather than Becca running at 4.5 miles per hour
Part B
Kimberly runs 25 miles, Becca runs 22.5 miles

0.01
can I have brainliest please
Step-by-step explanation:
Please view my other solution I gave you.
:)
But I will still answer this if you see it.
Because 0.8^x is never 0, then the asymptote is 0-10 or -10.
