GCF is 2
Answer: (q°r)(4) = 30
(r°q)(4) = 36
Step-by-step explanation:
First, when we have two functions f(x) and g(x), we have that:
(g°f)(x) = g(f(x))
So we are actually evaluating one function with other function.
Now, solving the problem:
q(x) = 2x - 2
r(x) = x^2
we have:
(q°r)(x) = q(r(x)) = 2*r(x) - 2 = 2*(x^2) - 2
(r°q)(x) = r(q(x)) = q(x)^2 = (2*x - 2)^2
Then:
(q°r)(4) = q(r(4)) = 2*r(4) - 2 = 2*(4^2) - 2 = 2*16 - 2 = 32 - 2 = 30.
(r°q)(4) = r(q(4)) = q(4)^2 = (2*4 - 2)^2 = 6^2 = 36.
Answer:
$1.6 per gallion
Step-by-step explanation:
. The rate of change of the cost of the taxi ride is $2.00 per minute.
Descending means that the hot air balloon's height is changing at a negative rate. Multiply the rate of change per minute by the total amount of minutes.
The total change in altitude is
-960 feet.
