Answer:
that is the nearest thousands decimal place
Answer:
8
Step-by-step explanation:
This one is similar to the other one done with graphs , the only difference is we have equations instead of graphs.
Like the other one, we want to find f(2) and whatever that equals we plug into g(x) to find g(f(2))
So first lets find f(2)
f(x) = x - 4
f(2) = 2 - 4
f(2) = -2
g(f(2)) , f(2) = -2 , g(-2)
now lets find g(-2)
g(x) = -2x + 4
g(-2) = -2(-2) + 4
multiply -2 and -2 to get 4
g(-2) = 4 + 4
add 4 and 4 to get 8
g(-2) = 8
We can conclude that g(f(2)) = 8
Answer: if S is the distance, the fact that the distance is proportional to the square of the time means that S(t) = a*
where a is a constant of proportionality, with units of
.
We know that S(1) = 16 feet = a*1, then a = 16
then S(2) = 16*4 feet = 64.
and if we want to know in how much time te objet will fall 400feet, then S(t₀) = 400 feet = 16*
so t₀ =
= 5s.
