Answer:
The height the ball bounces when dropped from a zero height
Step-by-step explanation:
The "initial value" of a function is usually the value of the function when the independent variable is zero. Here, that variable is the height from which the ball is dropped.
When the independent variable is zero, the "initial value" of the function would be the height the ball bounces when it is dropped from that (zero) height.
slope is rise over run.

Answer:
x = 20°
y = 70°
Step-by-step explanation:
the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)
in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°
to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°
