Afootball is kicked vertically upward from a height of 3 feet with an initial speed of 70 feet per second. the formula h=3+70t-16t^2 describes the ball's height above the ground, h, in feet, t seconds after it was kicked. use this formula to find the ball's height 3 seconds after it was kicked.
q. the ball's height, 3 seconds after it was kicked, was
feet.

69 feet

Step-by-step explanation:

3 seconds is a unit of time, t.  So if we want the height of the ball, h, 3 seconds after it was kicked, we plug in 3 for t and solve for h:

which simplifies to

h = 3 + 210 - 144 so

h = 69 feet

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
