Answer:
362%, 3.66, 3 2/3, 36
Step-by-step explanation:
Answer:
y=3.5x+4; A(_,5) B(10,_)
Step-by-step explanation:
.Find point A: Substitute y value given, solve for x:
.
5=3.5x+4
1=3.5x
1/3.5=x
0.2857=x
.
Point A=(0.2857,5)
.
Find point B: Substitute x value given, solve for y:
.
y=3.5(10)+4
y=35+4
y=39
.
Point B=(10,39)
.
Slope:
In slope intercept form y=mx+b, m=slope
.
Slope=m=3.5
.
The others are done the same way.
Answer:
A
Step-by-step explanation:
Just took the quiz
Answer:
120 MW/hour
Step-by-step explanation:
The formula of the average rate of change between two points in a function is:
Average rate of change (ARC) = f(x2) -f(x1)/(x2-x1)
Let's think the power demad as a function d(x) depending of the hour of the day, so the variable x= hour of the day.
Now we have:
d(5)= 1600
d(8)= 1960
If we apply the mentioned ARC formula = [d(8)-d(5)] MW/(8-5)hour= (1960-1600)MW/3hour= 360/3=120 MW/Hour
