Answer:
5.54 miles
Step-by-step explanation:
1. Assume she runs up to a point that is x miles to the east of the coral reef:
distance running =
distance swimming =
2. Times:
time= distance / speed
time running =
time swimming =
3. Total time
time running + time swimming:
4. Minimize time
The minimum time is when the derivative of the function of time is zero.
Find the derivative of T(x), using rule of the sum, the derivative of the sum is the sum of the derivatives, and the chain rule:
Solve for x:
5. Distance the visitor should run to minimize the time
Hence, the visitor should run 5.54 miles.

Answer:
2x+6≥6x−4-->-4x≥-10-->x≤2.5
4x>-1 --> x>1/4
Step-by-step explanation:
9% as a decimal would be 0.09 because a percent is a number out of one hundred which means 9% is equal to 0.09. When you compare 0.09 to 0.4, 0.4 would be greater.
