Answer:
78
Step-by-step explanation:
50 questions worth 2 a piece and you miss 11 questions so we are going to take 2(11) off of 50.
We are doing 100-2(11).
100-22=78.
Or if you miss 11 questions you get 39 right. So 39(2)=78.
<em>Substitute x = 2 as we get</em>
<em>f(2) = -4(2)+4 = -8+4 = -4</em>
<em>Therefore, f(2) = -4</em>
Answer:
B. 66.0
Step-by-step explanation:
The formula for circumference is 2*π*r where r is the radius. MS and MR are both radii, so we can plug in 10.5 to the formula to get 2* π*10.5, which would be about 65.97, which rounds to 66.0. Hope this helps!
