Initial: 200 feet = opp. side
Angle = 17.31, adj. Side = a
So tan (17.31) = opp. Side / adj. Side
tan (17.31) = 200 / a
--> a = 200/tan17.31 = 641.73
When stopped: adj. Still = a
Opp. Side still = 200, angle = 46.41
tan46.41 = 200 / a
--> a = 200/tan46.41 = 190.39
Now subtract those two distances to get the distance traveled from initial to when it stopped:
641.73 - 190.39 = 451.34 feet

The point ( - 14,12) is on the graph of y = f(x). Find the corresponding point on the graph of y= qe), where gex) = arcus.
liubo4ka [24]

Answer:

(-14,4)

Step-by-step explanation:

Given

(-14,12)   \to    y =f(x)

g(x) = \frac{1}{3}f(x)

Required

The corresponding point on y = g(x)

(-14,12)   \to    y =f(x) means:

12 = f(-14)

or

f(-14)=12

g(x) = \frac{1}{3}f(x) is calculated

g(-14) = \frac{1}{3} * f(-14)

g(-14) = \frac{1}{3} * 12

g(-14) = 4

So, the corresponding point on y = g(x) is: (-14,4)
