Answer:
When we have a function f(x) = y.
The rate of change between a and b (where a < b) is:
R = (f(b) - f(a))/(b - a)
In this case:
b = 3
a = 1
f(3) = 127
f(1) = 95
R = (127 - 95)/(3 - 1) = 16
The rate of change in that interval is 16.

Answer: To solve these types of questions what I always do is get a protractor if you have one and put it up against to where the dot is in the middle of the empty hole and then get a ruler or a pencil and make the line keep going to see what angle. In this case your answer is 65% I think.
Answer:
The pink angle is half the angle subtended by the blue arc.
Step-by-step explanation:
Given
See attachment for circle
Required
Compare the pink angle to the blue arc
Let the pink angle be x and the angle subtended by the blue arc be y.
So, we have:
angle at circumference
angle subtended by arc
The relationship between x and y is:
