Eric leans a ladder against the roof of his house so that the ladder forms a 70 degree angle with the ground. the roof of the house is 13 feet above the ground. how far is the bottom of the ladder from the base of the house? round the answer to the nearest tenth.
a. 0.2 feet
b. 4.4 feet
c. 4.7 feet
d. 71.2 feet

your answer would be letter c.

B I personally think..

Step-by-step explanation:

Hi,

Use Differential Formula :

d(u(x) • v(x))/dx = u'(x) • v(x) + u(x) • v'(x)

at x = 1 :

d(u(1) • v(1))/dx = u'(1) • v(1) + u(1) • v'(1)

d(u(1) • v(1))/dx = -5 • 6 + 4  • -2

d(u(1) • v(1))/dx = -30 - 8

d(u(1) • v(1))/dx = -38

Hope this helped :)
