Answer:
The indifference point is 200 miles
Step-by-step explanation:
<u>First, we need to establish the total cost formula for each company:</u>
Pack and Go:
Total cost= 39.95 + 0.45x
x= miles driven
U-Drive:
Total cost= 59.95 + 0.35x
x= miles driven
<u>Now, we equal both formulas and isolate x:</u>
39.95 + 0.45x = 59.95 + 0.35x
0.1x = 20
x= 200 miles
The indifference point is 200 miles
A= 1.142 m/hr
Width of beach at 8 p.m. = 36 m
Width of beach at 3 a.m. = (36-8) m =28 m
Average change in width(A) = change in width (Width of beach at 8 p.m.-Width of beach at 3 a.m.0/ time in hours
A= ( 36-28)/ 7
A= 8/7 m/hr
A = 1.142 m /hr
The side length is the square root of 8. Because the square has 4 equal sides, the side lengths must be equal. So the answer is approximately 2.83.
Answer : square root of x - 5 ,
the answer the the last option choice.
