Find the absolute maximum and absolute minimum values of f on the given interval. (If an answer does not exist, enter DNE.)
vodka [1.7K]

Answer:

absolute max is 120 and absolute min is -8

Step-by-step explanation:

Find critical numbers

f'(x) = 3x^2 - 12x + 9 = 0

= 3(x^2 - 4x + 3) = 0

3(x-3)(x-1) = 0

(x-3) = 0 or (x-1)=0

x = 1,3

Test them!

x<1     Sign of f' on this interval is positive

1<x<3 Sign of f' on this interval is negative

x>3    Sign of f' on this interval is positive

f(x) changes from positive to negative at x = 1 which means there is a relative maximum here.

f(x) changes from negative to positive at x = 3 which means there is a relative minimum here.

Test the endpoints to find the absolute max and min.

f(-1) = -8

f(1) = 12

f(3) = 8

f(7) = 120

The absolute maximum value of f is 120 and the absolute minimum value of f is -8.

A radar beacon 40 feet above the ground picks up an airplane approaching at an angle of elevation
viktelen [127]

5,998.7714 ft

Step-by-step explanation:

Well find x in the illustration;

First To find the opposite side of the right-angled triangle we'll using tangent of the given angle

Tangent Ф = Length of the opposite side / Length of the adjacent side

Tan 43 = h / 6390

h = Tan (43) * 6390

h = 5,958.7714 ft

Then we'll add the height of the beacon which is 40 ft above ground;

x = 5,958.7714 ft + 40 ft

x = 5,998.7714 ft
