This is a sketch of y = sin x. The vertex A is at (90°, 1).
A (90°, 1)
- -17
Write down the coordinates of the vertex A of the curve with equation
a) y = sin x + 2
b) y=-sin x

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
