Answer:
C. 3/2 Radians
Step-by-step explanation:
As we know, a radian is defined as "the angle enclosed by an arc equal to the radius", or some variant of such.
This means 1 radian in this circle would have an arc length of 8cm.
Simple proportions should get you an answer:
Note that for x = 0, you need f(0) = 2, so you can delete the second option.
For x = 1, you need f(1) = 4. So, the third option must to be removed.
For x = 2, you need f(2) = 8, the only that satisfies this value is the first option (between the first option and the fourth option), therefore the answer is the first option.
First, 45 is the total number of students. So you have to add the ratio: 2+3=5. Since you are finding the number of sixth graders, you need to use the ratio 2.
Sixth graders : All = x : 45
2 : 5 = x : 45
You could change this to fractions and solve it.
2/5 = x/45
x = 18
So there are 18 sixth graders.
