Answer:
1.
Step-by-step explanation:
First find the derivative of sin-1x.
This is a standard derivative and it is 1 /√(1 - x^2)
This is the slope of the graph at x.
Slope at x = 0 = 1 /√(1 - 0^2)
= 1/1 = 1,
X
X + 2
X + 4
3x + 6 = 258
3x + 6 - 6 = 258 - 6
3x = 252
X = 84
84 + 2 = 86
84 + 4 = 88
85 / 15 = 5 2/3
30 x 5 = 150
2/3 x 30 = 20
The answer is 170 seconds, or 2 minutes and 50 seconds
