(f•g)(2)=27, the distance in miles the bicycle traveled
Option D is correct.
Step-by-step explanation:
Rate of a bicycle traveling in miles per hour :
the time the bicycle traveled in hours:
We need to find (f.g)(2)
Solving:
So, (f•g)(2)=27, the distance in miles the bicycle traveled
Option D is correct.

Answer:
upward
Step-by-step explanation:
y=4x²+4
Look at the coefficient of x²
If it is positive, it opens upward, IF it is negative, it opens downward.
In this case, the x² coefficient is +4, hence it opens upward
(see attached for plot)
Answer:
See answer and graph below
Step-by-step explanation:
∬Ry2x2+y2dA
=∫Ry.2x.2+y.2dA
=A(2y+4Ryx)+c
=∫Ry.2x.2+y.2dA
Integral of a constant ∫pdx=px
=(2x+2.2Ryx)A
=A(2y+4Ryx)
=A(2y+4Ryx)+c
The graph of y=A(2y+4Ryx)+c assuming A=1 and c=2
