20 points-

a sine function has the following key features:

period = π

amplitude = 2

midline: y=−2

y-intercept: (0, -2)

the function is a reflection of its parent function over the x-axis.

use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.

Find two numbers if their sum is 91 and the ratio is 6: 7?

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
