PLEASE HELP, SOLVE THIS PROBLEM AND GIVE ME THE ANSWER!!!

B. -5.

Step-by-step explanation:

fg(x) = (x - 1)(5x^2 + 19x - 3)

= 5x^3  + 14x^2  - 22x + 3

So fg(-4) = 5(-4)^3 + 14(-4)2 -22(-4) + 3

= -320 + 224 + 88 + 3

= -5.

551.82feet tall

Step-by-step explanation:

WE are given the following from the question;

Distance of me from the bottom of the building = 1300feet (adjacent)

Angle of elevation = 23 degrees

Required

Height (opposite)

Using the SOH CAH TOA identity

Tan theta = opp/adj

Tan 23 = H/1300

H = 1300tan23

H = 1300(0.4245)

H = 551.82feet

Hence the building is 551.82feet tall
