Disagree. Even though it has no b it is still a line but a horizontal line. It will be at 7 on the y- intercept but horizontal.
B because all the others are further from 6
Answer:
6.2
Step-by-step explanation:
Answer: hypotenuse = ![c^{2} + b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%2B%20b%5E%7B2%7D)
Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side (
) of the right triangle, .i.e.:
![h^{2} = s_{1}^{2} + s_{2}^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%20%3D%20s_%7B1%7D%5E%7B2%7D%20%2B%20s_%7B2%7D%5E%7B2%7D)
In this question:
= ![c^{2}-b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D-b%5E%7B2%7D)
2bc
Substituing and taking square root to find hypotenuse:
![h=\sqrt{(c^{2}-b^{2})^{2}+(2bc)^{2}}](https://tex.z-dn.net/?f=h%3D%5Csqrt%7B%28c%5E%7B2%7D-b%5E%7B2%7D%29%5E%7B2%7D%2B%282bc%29%5E%7B2%7D%7D)
Calculating:
![h=\sqrt{c^{4}+b^{4}-2b^{2}c^{2}+(4b^{2}c^{2})}](https://tex.z-dn.net/?f=h%3D%5Csqrt%7Bc%5E%7B4%7D%2Bb%5E%7B4%7D-2b%5E%7B2%7Dc%5E%7B2%7D%2B%284b%5E%7B2%7Dc%5E%7B2%7D%29%7D)
![h=\sqrt{c^{4}+b^{4}+2b^{2}c^{2}}](https://tex.z-dn.net/?f=h%3D%5Csqrt%7Bc%5E%7B4%7D%2Bb%5E%7B4%7D%2B2b%5E%7B2%7Dc%5E%7B2%7D%7D)
=
, then:
![h=\sqrt{(c^{2}+b^{2})^{2}}](https://tex.z-dn.net/?f=h%3D%5Csqrt%7B%28c%5E%7B2%7D%2Bb%5E%7B2%7D%29%5E%7B2%7D%7D)
![h=(c^{2}+b^{2})](https://tex.z-dn.net/?f=h%3D%28c%5E%7B2%7D%2Bb%5E%7B2%7D%29)
Hypotenuse for the right-angled triangle is
