Answer:
He worked 8 hours.
Step-by-step explanation:
50 + 25 = 75
600 ÷ 75 = 8
Answer:
240
Step-by-step explanation:
The circuit's power is modeled by a quadratic function, whose graph is a parabola.
The maximum power is reached at the vertex.
So in order to find the maximum power, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into P(c).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.
Now let's take the zeros' average:
(0+8)/2=4.
The vertex's x-coordinate of this parabola is 4. Now let's find P(4).
P(4)=-15(4)(4-8)
240.
The maximum power of this circuit is 240 watts.
PLEASE MARK BRAINLIEST AND VERTIFIED ANSWER!! I spent a lot of time on this... :P thank you!!
The answer to this question is 2 square root 26
Coin probability = 1/2
Dice probability = 5/6
(1/2)x(5/6) = 5/12

Answer:
gradient M = 4
Step-by-step explanation:
pick any two pairs
M= change in Y / change in X
considering the last pairs
3--1/0--1=4✓
considering first pair
-1--5/-1--2 is also 4✓
I hope it helps
