Answer:
: c2 = a2 + b2 - 2ab cos C
c²=20²+15²-2×15×20×cos50
c²=400+225-600×0.64
c²=241
c=√241=15.5ft
we can establish a ratio since triangle MNQ is equal to Triangle MLP.
your answer is B 9 inches
Answer:
Algebrically the result can be written as -
![9 {x}^{2} + 24x + 16](https://tex.z-dn.net/?f=9%20%7Bx%7D%5E%7B2%7D%20%20%2B%2024x%20%2B%2016)
Step-by-step explanation:
Let the number be 'x'.
- When multiplied by 3 , algebrically it is written as "3x".
- When 4 is added to 3x , algebrically it is written as "3x + 4".
- When (3x + 4) is squared completely , algebrically it is written as -
![{(3x + 4)}^{2} = 9 {x}^{2} + 24x + 16](https://tex.z-dn.net/?f=%20%7B%283x%20%2B%204%29%7D%5E%7B2%7D%20%20%3D%209%20%7Bx%7D%5E%7B2%7D%20%20%2B%2024x%20%2B%2016)
Average rate of change from x = -3 to x = 1 is (f(1) - f(-3))/(1 - (-3)) = (5 - (-3))/(1 + 3) = (5 + 3)/4 = 8/4 = 2
