Answer:
The answer is
a) <u>2,128 miles per gallon at 40,36 miles per hour</u>
b) <u>1,388 miles per gallon at 60 miles per hour</u>
Step-by-step explanation:
Let's find the extreme points of M(x) for 30≤x≤60. M(x) simplified by dividing to 7.8.
To find extreme points we find tangent of M(x) and equal it to 0.
therefore x=
This divides our x to 2 different range 30≤x≤40,36 and 40,36≤x≤60
Now we pick a number and investigate from the ranges
30≤x≤40,36 → x = 35 → <u>M'(35) = 0,0206</u><u> which is </u><u>> 0</u><u> and that means M is increasing</u>
40,36≤x≤60 → x = 45 → <u>M'(45) = -0,0178</u><u> which is </u><u>< 0 </u><u>and that means M is decreasing</u>
Next let's look at critical points
x M(x) Before After Decision
30 1,922 - ↑ Local Minimum Point
40,36 2,128 ↑ ↓ Local Maximum Point
60 1,388 ↓ - Local Minimum Point
As we can see (30, 1,922) and (60, 1,388) are<u> local minimum points</u> and (40,36 , 2,128) is the <u>local maximum point</u>.
Since (60 , 1,388) is the <u>lowest local minimum point</u> it is the absolute minimum point and (40,36 , 2,128) is the absolute maximum point.
