3 gallons x 4 qt/gallon = 12 quarts total.
He used 9, so he has 12 qt. - 9 qt. remaining.
3 Quarts remain.
Answer:
6 seconds
Step-by-step explanation:
We have to find the t-intercepts of the function. To do so, let's set h(t) = 0.
0 = 96t - 16t²
0 = 16t(6 - t) -- Factor 96t - 16t²
16t = 0 or 6 - t = 0 -- Use Zero Product Property
t = 0 or t = 6 -- Solve for t
We're not looking for the solution t = 0 because that represents when the debris was launched. Therefore, the answer is 6 seconds.
if the slope is going down then its negative but if the line is going up its positive
Answer:
x = 1/2 ± √2 / 2
Step-by-step explanation:
4x²-4x-1=0
Roots: x = (-b ± √b² - 4ac) / 2a a=4 b=-4 c=-1
x = (- -4 ± √(-4)² - 4*4*(-1)) / 2*4
x = (4 ± √32) / 8 = (4 ± 4√2) / 8 = 1/2 ± √2 / 2
