Answer:
B. y = 1/3x + 3
Step-by-step explanation:
(7, 1) and (1,8)
slope = (8 - 1)/(1-7) = -7/6
so
y - 1 = -7/6(x - 7)
y - 1 = -7/6 x + 49/6
y = -7/6 x + 55/6
answer
A. first one
y = -7/6 x + 55/6
Answer:
-8x^2 -4x
Step-by-step explanation:
f(x) = –4x – 2
g(x) = 2x
(f · g)(x) = (-4x-2) * (2x)
distribute
= -2x*4x -2x*2
= -8x^2 -4x
according to the graph at x= -2
y = 3
Ф is the angle of elevation to the topo of the building from G.
length of leg adyacent to angle Ф=40m
length of leg opposite to angle Ф=15 m
tan Ф=leg opposite / leg adyacent=15/40=0.375
Ф=arctan 0.375=20.56º
The angle of elevation to the top of the building from G is 20.56º.
