Answer: 4) y = -1/3x² + 2x - 1
Step-by-step explanation:
Given :
y = 
+ 2
Expanding (x-3)² will give :
- 6x + 9
substituting into the function , we have :
y = ![( [tex]x^{2}](https://tex.z-dn.net/?f=%20%28%20%5Btex%5Dx%5E%7B2%7D)
- 6x + 9 ) + 2
Expanding , we have
y = + 2x - 3 + 2
y = + 2x - 1
Answer:
1.16 in
2.24 in
3.12.8 in
Step-by-step explanation:
We are given that
Width of photo=5 in
Length of photo=8 in
We have to find the length of new photo in each case.
1. Let x represent the width and y represents the length of photo.
When width increase then length of photo is also increases then it is direct proportion.
Substitute the values then we get
Hence, the length of photo=16 in
2.Width=x=15 in
Again using the formula
Hence, the length of new photo=24 in
3. Width =x=8 in
Substitute the values in the given formula
Hence, the length of new photo=12.8 in
14•10,000=140,000+12,000=152,000
You did the equation a little wrong. It is A^2 + B^2 = 10^2
