Answer:
I think that the answer to this question is the third one . I mean 29 .
Assuming Earth's gravity, the formula for the flight of the particle is:
s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160.
This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2.
Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.
Answer:The x has to be alone meaning it has to be before or after the equation to solve, what you to do one side of the equation you will always do to the other side.
Step-by-step explanation:
Answer:
y = 25
Step-by-step explanation:
Given that the quantities are proportional then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 10 when x = 6
k = 
= 
= 
y = x ← equation of proportion
When x = 15, then
y = × 15 = 5 × 5 = 25
Answer:
4xy
Step-by-step explanation:
We need to subtract 2xy from 6xy, So that is,
=> 6xy - 2xy
=> 4xy
