Answer:
39.55
Step-by-step explanation:
24.99+15=39.55
That is how you get your answer :)
No, because you're not actually moving.
we know that
the equation of a circle with the center at the origin is equal to

step 1
with the point (3,0) find the value of the radius
substitute the values of

in the equation of the circle above
so



step 2
with the radius find the area of the circle
area of the circle is equal to

for 

units²
therefore
the answer is
the area of the circle to the nearest hundredth is
units²
f(x) = 5x + 1
f(4) = 5 * 4 + 1
f(4) = 20 + 1
f(4) = 21
g(x) = 2x² - 3x +1
g(5) = 5 * 5² - 3 * 5 + 1
g(5) = 125 - 15 + 1
g(5) = 111
f(4) + g(5) = 21 + 111 = 132
