Answer:
15
Step-by-step explanation:
8² + 15² = c²
To find : Value of c
8² = 8 x 8 = 64
15² = 15 x 15 = 225
c² = 225
225 = 15 x 15 = 15²
So,
c² = 15²
c = 15

Given:
Two values of a linear function are f (6) = 8 and f (9) = 3.
To find:
The linear function.
Solution:
According to the question f (6) = 8 and f (9) = 3, it means the function passes through (6,8) and (9,3).
If a linear function passes through two points then the equation is
![y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29)
So, the equation of linear function is
![y-8=\dfrac{3-8}{9-6}(x-6)](https://tex.z-dn.net/?f=y-8%3D%5Cdfrac%7B3-8%7D%7B9-6%7D%28x-6%29)
![y-8=\dfrac{-5}{3}(x-6)](https://tex.z-dn.net/?f=y-8%3D%5Cdfrac%7B-5%7D%7B3%7D%28x-6%29)
![y-8=-\dfrac{5}{3}(x)-\dfrac{5}{3}(-6)](https://tex.z-dn.net/?f=y-8%3D-%5Cdfrac%7B5%7D%7B3%7D%28x%29-%5Cdfrac%7B5%7D%7B3%7D%28-6%29)
![y-8=-\dfrac{5}{3}(x)+10](https://tex.z-dn.net/?f=y-8%3D-%5Cdfrac%7B5%7D%7B3%7D%28x%29%2B10)
Add 8 on both sides.
![y=-\dfrac{5}{3}(x)+10+8](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B5%7D%7B3%7D%28x%29%2B10%2B8)
![y=-\dfrac{5}{3}(x)+18](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B5%7D%7B3%7D%28x%29%2B18)
Function form is,
![f(x)=-\dfrac{5}{3}(x)+18](https://tex.z-dn.net/?f=f%28x%29%3D-%5Cdfrac%7B5%7D%7B3%7D%28x%29%2B18)
Therefore, the required linear function is
.
