The path of a diver diving off a 10-foot platform can be represented by the
function h(x) = -0.5(x2 - 4x -
21), where h is the diver's height above
water and x is the horizontal distance
from the platform (in feet).

Find the zeros of the function.

uhhh idk u yolo?

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

the probability that a bird is green (.30) is true
