Answer:

5 meters

Step-by-step explanation:

We should derive an equation to solve this problem.

Let's assign x to width and y to length.

2x-4=y

and

2x+2y=22

so

2x+2(2x-4)=22

2x+4x-8=22

6x-8=22

6x=30

x=5

Width = 5 meters

the power generated by an electrical circuit (in watts) as a function of its current C (in amperes) is modeled by P(c)= -15c(c-8
katen-ka-za [31]

Answer:

c = 4 A

Step-by-step explanation:

The given function P(c) = - 15 c (c-8) is actually quadratic function:

P(c) = - 15c² + 120c    or parabola

The standard form of a quadratic function is:

y = ax² + bx + c

For which x is the maximum of the parabola we can find with this formula

x = - b/2a

in this case a = -15 and b = 120 and input variable is current c

c = - 120/(2 · (-15)) = - 120/ (-30) = 4 A

c = 4 A

God with you!!!
