User: h = - 16t2 - 32t + 320 gives the height of a ball, thrown downward from the top of a 320 foot building with an initial velocity of 32 feet per second.
Find the time in seconds that it takes for the ball to reach a height of 48 feet.

Weegy: ((3)/(1)/(3))((6)/(1)/(2))
To divide by 3, [ multiply by the reciprocal.
((3)/(1)*(1)/(3))((6)/(1)/(2))
Cancel the common factor of 3 from the first term 3 and the denominator of the second term (1)/(3).
(1*1)((6)/(1)/(2))
Multiply 1 by 1 to get 1.
(1)((6)/(1)/(2))
To divide by 2, multiply by the reciprocal.
(1)((6)/(1)*(1)/(2))
Cancel the common factor of 2 from the first term 6 and the denominator of the second term (1)/(2).
(1)(3*1)
Multiply 3 by 1 to get 3.
(1)(3)
Multiply 1 by 3 to get 3.
(3)
Remove the parentheses around the expression 3....
3 is the answer. ] (More)
