Answer:
<h3>AB ≈ 70m</h3>Step-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
Given , revenue function :
Cost function
Profit = Revenue - Cost
Hence, P = R(x) - C(x)
Total revenue for x = 12000 is
Total cost for x = 12000,
Profit = 60000-28500 = 31500
Answer = 31500
