The maximum profit is the y-coordinate of the vertex of the parabola represented by the equation.

P(c)=-20c^2+320c+5120 \\ \\
a=-20 \\
b=320 \\ \\
\hbox{the vertex } (h,k): \\
h=\frac{-b}{2a}=\frac{-320}{2 \times (-20)}=\frac{-320}{-40}=8 \\
k=f(h)=f(8)=-20 \times 8^2+320 \times 8+5120= \\
=-1280+2560+5120=6400

The maximum value is 6400, but the profit is given in hundreds of dollars, so multiply the value by 100.

The maximum profit the company can make is $640,000.

What’s the value of n in the equation-1/2(2n+4)+6=-9+4(2n+1)
klemol [59]

Answer:

n=13/7

Step-by-step explanation:

2n+4+6*2=-9*2+8(2n+1)

2n+4+12=-18+16n+8

16+18=16n-2n+8

34=14n+8

34-8=14n

26=14n

n=13/7
