C.
Although this is not the exact answer the circumference formula is 2(pi)r. Which is far more than the other two options.
Answer:
f(4) = -10
g(2) = 30
Step-by-step explanation:
X(30;0)
y(0;50)
substitue 0 for y and solve for x
substitute 0 in for x and solve for y
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7
and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so
to find the intersection, yo just find when both sentances are correct so
y=7
subsitute that into y=1/2x+6
7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x
so the point (2,7) is the intersection
