Answer:
Step-by-step explanation:
32
Your answer would be 4 over x to the sixth which would look like this
4
_
x^6
the ^ symbol means it’s an exponent
The formula of a midpoint SR:
![M\left(\dfrac{x_S+x_R}{2},\ \dfrac{y_S+y_R}{2}\right)](https://tex.z-dn.net/?f=M%5Cleft%28%5Cdfrac%7Bx_S%2Bx_R%7D%7B2%7D%2C%5C%20%5Cdfrac%7By_S%2By_R%7D%7B2%7D%5Cright%29)
We have
S(4, 1) and M(7, -5)
Substitute:
![\dfrac{4+x_R}{2}=7\qquad|\cdot2\\\\4+x_R=14\qquad|-4\\\\x_R=10\\\\\dfrac{1+y_R}{2}=-5\qquad|\cdot2\\\\1+y_R=-10\qquad|-1\\\\y_R=-11](https://tex.z-dn.net/?f=%5Cdfrac%7B4%2Bx_R%7D%7B2%7D%3D7%5Cqquad%7C%5Ccdot2%5C%5C%5C%5C4%2Bx_R%3D14%5Cqquad%7C-4%5C%5C%5C%5Cx_R%3D10%5C%5C%5C%5C%5Cdfrac%7B1%2By_R%7D%7B2%7D%3D-5%5Cqquad%7C%5Ccdot2%5C%5C%5C%5C1%2By_R%3D-10%5Cqquad%7C-1%5C%5C%5C%5Cy_R%3D-11)
<h3>Answer: R(10, -11)</h3>
Answer:
6.8
Step-by-step explanation:
a^2 + b^2 = c^2
6.6^2 + b^2 = 9.5^2
43.56 + b^2 = 90.25
b^2 = 90.25 - 43.56
b^2 = 46.69
(take square root of both sides)
b = 6.8
