H=-16t^2+46t+6 after how many seconds will the ball hit the ground?
ANEK [815]
Ball hit the ground is when the function equals zero
0=-16t^2+46t+6
we can't factor so use quadraticformula

for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-46+/- \sqrt{46^2-4(-16)(6)} }{2(-16)}
x=\frac{-46+/- \sqrt{2116+384} }{-32}
x=\frac{-46+/- \sqrt{2500} }{-32}
x=\frac{-46+/- 50 }{-32}
x=\frac{-46+ 50 }{-32} or \frac{-46- 50 }{-32}
x=\frac{4}{-32} or x=\frac{-96}{-32}
x=-1/6 or x=3

we cannot have negative time because time starts at 0
disregard -1/6 as a possible answer


answer is after 3 seconds

My problem is : P=2L+2W solve for L
natima [27]
Answer:
L = P/2 - W

Explanation:
Step 1 - Start by factoring out the two

P = 2L + 2W
P = 2(L + W)

Step 2 - Divide both sides of the equation by two

P = 2(L + W)
P/ 2 = 2(L + W)/ 2
P/ 2 = L + W

Step 3 - Subtract W from both sides of the equation

P/ 2 = L + W
P/ 2 - W = L + W - W
P/ 2 - W = L
