This is what i got if i had done my math right. I hope this helps.
y • (2y2 - 16y + 1)
Answer:
5 (1/2)
Step-by-step explanation:
Answer:
A is the answer
vertically stretched by a factor of 2
Step-by-step explanation:
f(x) = √x and f(x) = 2√x
Since |a| = 2 > 1. The line f(x) = 2√x is vertically stretched by a factor of 2
from f(x) = √x
Answer is A
The diagram of the ladder leaning on a wall is shown below
We will use the trigonometry ratio for cosine to solve for 'x'
We choose the cosine ratio because we have the angle, 61° and the side adjacent to the angle
![cos(x)= \frac{adjacent}{hypothenuse}](https://tex.z-dn.net/?f=cos%28x%29%3D%20%5Cfrac%7Badjacent%7D%7Bhypothenuse%7D%20)
![cos(61)= \frac{61}{x}](https://tex.z-dn.net/?f=cos%2861%29%3D%20%5Cfrac%7B61%7D%7Bx%7D%20)
![x= \frac{6}{cos(61)} =12.38](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B6%7D%7Bcos%2861%29%7D%20%3D12.38)
, rounded to 2 dp
