A ball is thrown across a playing field from a height of h=5ft above the ground at an angle of 45 degrees to the horizontal at the speed of 20ft/s. It ca be deduced from physical principles that the path of the ball is modeled by the function

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

its very big question plz make it small

the answer is a.

606.0 sq. in.

i got it down.

15 / 2 = 7.5

100 / 7.5 = 13.
