For this case we have the following equation:
h (t) = at ^ 2 + v * t + h0
Substituting values we have:
h (t) = - 16 * t ^ 2 + 60 * t + 3
We equate the equation to zero:
-16 * t ^ 2 + 60 * t + 3 = 0
We look for the roots of the polynomial:
t1 = -0.04935053979258153
t2 = 3.7993505397925817
We are left with the positive root and round:
t2 = 3.8 s
Answer:
t = 3.8 s
option 3
Answer:
5
Step-by-step explanation:
perpendicular slopes multiply to -1
lets say m is the missing slope
-1/5*m=-1 so m=5
B. is true. 15·(–5) > 23·(–12).
15·(-5)=-75.
23·(-12)=-276.
-75 > -276
Answer:
2.25
Step-by-step explanation:
The old width of 4 inches became a new width of 9 inches.
Old: 4 in.
New 9 in.
The old length of 6 inches became a new length of 13.5 inches.
Divide the new size by the corresponding old size.
9/4 = 2.25
13.5/6 = 2.25
You see in both cases, the scale factor is 2.25
The scale factor is 2.25
166
I guess you just subtract the numbers
297-131=
