-72
Step-by-step explanation:
-32 + (2-6)(10)
-32 + (-4)(10)
-32 + -40
-72
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.

Answer:
The coefficient is 
Step-by-step explanation:
From the question we are told that



Generally the coefficient of determination is mathematically represented as
![r = [ \frac{cov(x,y)}{ \sqrt{s_x^2} * \sqrt{s_y^2} } ]^2](https://tex.z-dn.net/?f=r%20%20%3D%20%5B%20%5Cfrac%7Bcov%28x%2Cy%29%7D%7B%20%5Csqrt%7Bs_x%5E2%7D%20%2A%20%20%5Csqrt%7Bs_y%5E2%7D%20%7D%20%20%20%5D%5E2)
substituting values
![r = [ \frac{ 1260}{ \sqrt{1600} * \sqrt{1225} } ]^2](https://tex.z-dn.net/?f=r%20%20%3D%20%5B%20%5Cfrac%7B%201260%7D%7B%20%5Csqrt%7B1600%7D%20%2A%20%20%5Csqrt%7B1225%7D%20%7D%20%20%20%5D%5E2)
