*Hint: When an equation has | it means the absolute value.
Up in the attachment I have provided above is the way that equation should be graphed.
Because the x is squared, it's known that the graph will have a parabola. The -4 is showing the indent it will have.
Answer:
A≈12.57
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving for A
A=1
4πd2=1
4·π·42≈12.56637
I need help too you not alone in this but I think photo math would help
Is that Chole and Dave <em>each </em>get 2.5 times Ann? Let's assume so.
A:B=2 : 9
A:C:D=1 : 2.5 : 2.5
We can scale ratios without changing them, like fractions.
A:C:D=2:5:5
With A the same in both ratios we can put them together.
A:B:C:D=2:9:5:5
There's some scale factor k such that
k(2+9+5+5)=399
k = 399/21 = 19
