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:
7.5 hours
Step-by-step explanation:
240 = 6k
k = 240/6
k = 40
Miles = 40 × hours
300 = 40 × hours
hours = 300/40
= 7.5 hours
Answer:

Step-by-step explanation:
Triangle

Semicircle

because both semicircle are the same just multiply by 2

Now add all together

Answer:
x-intercept (0,0)
y-intercept (0,0)
Step-by-step explanation:
The given function is

To find the x-intercept, we substitute y=f(x)=0
This implies that:





Therefore the x-intercept is (0,0)
To find the y-intercept we substitute x=0


The y-intercept is (0,0)
