Answer:x=6,y=−1
Step-by-step explanation:
835/ 10 is 83.5
So his average rate of change is 83.5 miles per hour
If sinα=1/4 and it is in q2 it means that the x coordinate is negative.
The triangle has a height of one and a hypotenuse of 4 so:
x=-√(4^2-1)
x=-√15
so tanα=-1/√15
tanα=-√(1/15)
tanα≈ -0.258
If I did the math right, it should be D) 12 m
