Equation
2/3 = 14/ x
Cross multiply
2xX = 14x3
2x = 42
Eliminate
2x/2 = 42/2
X = 21
Answer:
10
Step-by-step explanation:
radius is the middle point of a circle, therefore divide it in half.
-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1
Answer:
(h,k) shows the coordintes of the turning point.
