A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t where t equals the
Vitek1552 [10]

Answer:

Last one

t = 1.5; it takes 1.5 seconds to reach the maximum height of 36 meters.

Step-by-step explanation:

h(t) = −16t² + 48t

h(t) = -16(t² - 3t)

h(t) = -16(t² - 2(t)(1.5) + 1.5² - 1.5²)

h(t) = -16(t - 1.5)² + 36

Axis of symmetry:

t = 1.5

Max height = 36

31/6 as a mixed number
liubo4ka [24]
Hello there awesome brainly user!

To convert \frac{31}{6} to a mixed number you have to divide 31/6 which equals 5 R 1 Remember that the remainder is the numerator and the whole number is 5. So, the mixed fraction is 5\frac{1}{6}

For further info, message me

Thanks and have a good day.
