An airplane traveling at 400mph at a cruising altitude of 6.5mi begins its descent. If the angle of descent is 2° from the horizontal, determine the new altitude after 15min. Round to the nearest tenth of a mile.

divide by 5

step-by-step explanation:

60/5 = 12

i got 86 for this

hope this !

if you need an explanation just ask

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
