C(h) = −0.09h^2 + 3.5h + 8
sub in 3 for H
C(3) = -0.09(3)^2 + 3.5 (3) + 8
=17.69 ppm
Hope that helps! :)
Answer:
Step-by-step explanation:
A(0,0), B(2,0), C(3,-3)
Perpendicular bisector of AB: x=1
Perpendicular bisector of AC: y=x-3
Center of circle = intersection of perpendicular bisectors = (1,-2)
Radius = √5
(x-1)² + (y+2)² = 5

The resulting equation will be x + y = 4 and 4y =20
<h3>System of equation</h3>
GIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
Adding both equation
3y + y = 12 + 8
4y = 20
Hence the resulting equation will be x + y = 4 and 4y =20
