Answer:
$17.14
Step-by-step explanation:
Given : ![y = - 0.34x^2 + 4.43x + 3.46](https://tex.z-dn.net/?f=y%20%3D%20-%200.34x%5E2%20%2B%204.43x%20%2B%203.46)
To Find : Using the quadratic regression equation, what was the predicted profit in year 8
Solution :
![y = - 0.34x^2 + 4.43x + 3.46](https://tex.z-dn.net/?f=y%20%3D%20-%200.34x%5E2%20%2B%204.43x%20%2B%203.46)
Where y is profit and x is year
Substitute x = 8
![y = -0.34(8)^2 + 4.43(8) + 3.46](https://tex.z-dn.net/?f=y%20%3D%20-0.34%288%29%5E2%20%2B%204.43%288%29%20%2B%203.46)
![y =17.14](https://tex.z-dn.net/?f=y%20%3D17.14)
So, Option D is true
Hence the predicted profit in year 8 is $17.14
Answer:
You need to divide them all separately and then add the answers together to get the correct answer
First multiple everything in the parentheses by
3
3 (2x+3)-6=
3(2x)+3(3)-6=
6x+9-6
then add together like terms
6x+9-6=
6x+3
so 6x+3 is your answer
Yes it does it has that cause that's what it mean cm 2
