Answer:
2x + 18k = X= -9k
Step-by-step explanation:
you have to solve the rational equation by combining expressions and isolating the variable x.
Answer:
x = 15
Step-by-step explanation:
create a proportion: <u> x + 10 </u> = <u> x + x + 10 </u>
5 8
cross-multiply: 8(x + 10) = 5(2x + 10)
8x + 80 = 10x + 50
80 = 2x + 50
30 = 2x
15 = x
Answer:The number of seconds after rocket is released
Step-by-step explanation:
Given
The height of a rocket after it is released is modeled by

Here t represent the number of seconds after the rocket is released.
Initial velocity can also be determined by this equation by differentiating the
w.r.t time

at t=o

thus initial velocity will be 32 units/s
