The equation for this problem would be,
s = seconds
f = feet
s * 20 = f
So the elevator travels,
s f
1 20
2 40
3 60
4 80
5 100
Because if the exponent is an even number, x can also be -x. For example, -4^2=4^2 but -4^3 isn't the same as 4^3
Sin∠R = ST/RS ⇒ ST = RS * sin40° = 9 * 0.6428 ≈ 5.8
The answer to your problem would be 2Y +3x=6
Answer:
-6/9 = -2/3 (C)
