Answer:No the student was not right.Neither of the estimations were right because she did not estimate at al.
Step-by-step explanation:
1.Round 49 to the nearest ten: 50.
2.Round 184 to the nearest ten:180.
3.Add 50+180 to get 230.
The student was not right because she did not estimate 49 nor 184.
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
