Well C=Dπ so C=17 x 3.14 = 53.38 which is rounded to 53.4
Answer: B
Step-by-step explanation:
<u>Given:</u>
36=<1.02D-31.2<=41
<u>Solve the compound inequality for D:</u>
36+31.2<=1.02D<=41+31.2
67.2<=1.02D<=72.2
65.9<=D<=70.8
Therefore, option (b) is correct answer
Answer:
yeet
Step-by-step explanation:
Answer:
Explanation:
<u>1. Assume she runs up to a point that is x miles to the east of the coral reef:</u>
- distance running =
- distance swimming =
<u>2. Times:</u>
time= distance / speed
- time running =
- time swimming =
<u>3. Total time</u>
- time running + time swimming:
<u>4. Minimize time</u>
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:
<u>5. Distance the visitor should run to minimize the time</u>
Hence, the visitor should run miles.
