Answer: y = 1
so 1! hopefully I helped!
Step-by-step explanation:
Answer:
5 amperes will produce the maximum power
Step-by-step explanation:
The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by: P(c)= -12c^2 + 120c.
To find out the maximum power we need to find the vertex
formula to find x -coordinate of vertex is 
P(c)= -12c^2 + 120c is given in the form of y=ax^2+bx+c
a= -12, b = 120

c= 5 amperes will produce the maximum power
Answer:
A and C
Step-by-step explanation:
This would be the correct answers because they are congruent and dilated from each other
Think of it like an equation: (w = width, l = length)
5 = 2w - l
lw = 150
l = 150 / w
5 = 2w - (150/w)
5w = 2w^2 - 150
2w^2 - 5w - 150 = 0 <- you can see this is now a quadratic equation
w = (-b^2 + sqrt(b^2 - 4ac))/2a
w = 10
width = 10
