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
y = -x + 5
Slope of this line = - 1.
Slope of the line that is perpendicular is negative reciprocal.
For example if slope= a/b, then slope of the perpendicular line = -b/a.
For our line, the slope is going to be -(-1)=1.
y=mx +b
m=1
y=x+b
We need to find b. We are going to use point (5, -1).
y = x +b
-1 = 5 + b
b= -6
So,
y= x - 6
Answer is A.
Answer:
2x+ 5
Step-by-step explanation:
Answer:
A= pi r(r+h2+r2)
Step-by-step explanation:
Multiply the radius by pi, then set that aside for a bit.
Square the height and the radius as well, then add those together. This is how it would look:
3.14 x 4 = 12.56
7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56
I think this is the answer. Can't say I'm 100% sure, though.
Step-by-step explanation:
✰ 
- 7 , 8 , 2 , 3 , 9 , 3 , 7
Here ,
- Frequency of 7 = 2
- Frequency of 8 = 1
- Frequency of 2 = 1
- Frequency of 3 = 2
- Frequency of 9 = 2
➺ 7 and 3 has the highest frequency i.e 2. So , Mode of the given data is 3 & 7 .
Hope I helped ! ♡
Have a wonderful day / night ! ツ
