Answer:
Step-by-step explanation:
If a tangent and a secant connect to an exterior point of a circle, the tangent squared is equal to the product of the two segments the secant creates.
Therefore, we have:
Answer:
RoC is 0.75 (3/4); Equation is y=0.75x )
Step-by-step explanation:
You can easily spot that first column, x increases by 1 each line, while the second, y, increases by 0.75.
Rate of change is variation in y divided by the variation in x, or . Replacing with the value we found, we get that the rate of change is
or
.
To find the equation the easiest way is to go back 4 steps, at the same rate of change, in order to find what's the value for x=0. Going back by 0.75 each step starting from 4, we obtain 2.25, 1.5, 0.75, and finally 0. Our equation becomes
