Answer:
h = 46
Step-by-step explanation:
-18 + h = 28
Add 18 to each side
-18+18 + h = 28+18
h =46
In this question , we have the formula of acceleration given, which is

And we have to solve for 
First we need to get rid of denominator t from right side and for that, we multiply both sides by t, that is

Now to solve for v1 , we need to get rid of v0, and for that , we add v0 to both sides, that is

And that's the required answer.
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(10,-8)...x1 = 10 and y1 = -8
(4,0)...x2 = 4 and y2 = 0
now sub and solve
d = sqrt (4 - 10)^2 + (0 -(-8)^2
d = sqrt (-6^2) + (8^2)
d = sqrt (36 + 64)
d = sqrt 100
d = 10 <==
A. 14 (7x2=14)
b. 8 (8x3=24)
c. 11 (no other numbers except 1 and 11 multiply to get 11)
