Aball is kicked straight up into the air. the height of the ball in feet is given by the expression -16t2+ 12t+ 4, where t is time in seconds. factor the expression. then find the height of the ball after 1 second.

0 feet.

Step-by-step explanation:

h =  -16t^2 + 12t + 4

h = -4(4t^2 - 3t - 1)

= -4(4t + 1)(t - 1)

After 1 second height = -4 * 1 * 0 = 0 feet.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

step-by-step explanation:

25+6=31
