Oh yeah sweetie I’m gonna say that lol I got lied
Answer:
1)
, 2)
.
Step-by-step explanation:
1) The ordered pair of the parabola is:
![f(0) = 0^{2} - 6\cdot (0) -27](https://tex.z-dn.net/?f=f%280%29%20%3D%200%5E%7B2%7D%20-%206%5Ccdot%20%280%29%20-27)
![f(0) = -27](https://tex.z-dn.net/?f=f%280%29%20%3D%20-27)
![(x,y) = (0,-27)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%280%2C-27%29)
2) The quadratic function needs to be rearranged into the standard form:
![y = x^{2}-6\cdot x -27](https://tex.z-dn.net/?f=y%20%3D%20x%5E%7B2%7D-6%5Ccdot%20x%20-27)
![y = x^{2} - 6\cdot x + 9 -9 -27](https://tex.z-dn.net/?f=y%20%3D%20x%5E%7B2%7D%20-%206%5Ccdot%20x%20%2B%209%20-9%20-27)
![y = (x-3)^{2}-36](https://tex.z-dn.net/?f=y%20%3D%20%28x-3%29%5E%7B2%7D-36)
![y + 36 = (x-3)^{2}](https://tex.z-dn.net/?f=y%20%2B%2036%20%3D%20%28x-3%29%5E%7B2%7D)

Answer:
$5202
Step-by-step explanation:
The total surface area of the cuboidal hall is:
2LB + 2BH + 2LH.
This will be: 2(40*3) + 2(3*15) + 2(40*15)
which will give : 1530m square.
The cost of 25msq of paint is 10
then the cost of 1530 will be 1530x10/25 = 612.
The cost of 1msq of tiles is 3
then the cost of 1530 will be 1530 x 3
= 4590.
Then the total cost will be =$5202
Answer:
|7 - n|
Step-by-step explanation:
Finding a difference means finding what that number is subtracted by another number, and then finding the absolute value of your result.
Assuming "a number" = n, the <u>difference</u><em> </em>of a number and 7 is |7 - n|
