Answer:
± 1/4 sqrt((400-y)) =t
Step-by-step explanation:
Y=-16t^2 + 400
Subtract 400 from each side
y - 400 = -16t^2 +400-400
y-400 = -16t^2
Divide by -16t^2
(y-400)/-16 = t^2
(400-y)/16 = t^2
Take the square root of each side
±sqrt((400-y)/16) =sqrt(t^2)
±sqrt((400-y)) / sqrt(16) =t
± 1/4 sqrt((400-y)) =t
Answer:
4x + 1
Step-by-step explanation:
g(f(x)) = (4x + 3) - 2
= 4x + 1
Mark is 20. 55 - 15 = 40, 40 / 2 = 20. Mark is 20
Answer:
x = 40
Step-by-step explanation:
x/5 = 8 is a problem in division. The inverse operation of division is multiplication.
To isolate x, multiply both sides of this equation by 5, obtaining:
x = 40
