Answer:
The answer to your question is
a) 400
b) The function has two real solutions (-2 and 8)
Step-by-step explanation:
Process
1.- Discriminant = b² - 4ac
= 12² -4(-2)(32)
= 144 + 256
= 400
2.- Solutions (using the general formula)
x = 
x = 
x = 
x₁ = 
x₂ = 
This function has two real solutions (-2, 8)
Answer:
(4²πx2) + (8π x 4) = 201.061... OR 64π
Ten million ten thousand four hundred sixty eight
Answer:
Decreasing
Step-by-step explanation:
If I started at the y point and follow the graph line. Then you will see that I will be going down the graph.
Hope this helped
Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
y = 4x
