The slope of the line is m=1/2
Answer: 32.23°
Suppose the setpoint of a helicopter is A and that of a car is C and that of the road is B
The distance from the helicopter to the car and the road forms a right triangle
=> ΔABC is a right triangle at B
=> the angle of depression from the helicopter from the car is ∠ACB
we have: ΔABC is a right triangle => sin ∠ACB = 24/45
=> m∠ACB = 32.23°
Step-by-step explanation:
They read for 39 minutes as that is the difference in time from when they started to when they finished.

|4x - 9| = 19 ⇔ 4x - 9 = 19 or 4x - 9 = -19 |add 9 to both sides
4x = 28 or 4x = -10 |divide both sides by 4
x = 7 or x = -2.5
Answer: (C) 7.

m = (p/q)^4 = p^4/q^4; n = (q/p)^(-2) = q^(-2)/p^(-2)
m/n = (p^4/q^4)/[q^(-2)/p^(-2)] = (p^4/q^4) · [p^(-2)/q^(-2)]
= p^(4-2)/q^(4-2) = p^2/q^2 = (p/q)^2
Answer: (C) (p/q)^2.
