Answer:
Step-by-step explanation:
The mapping rule is another form used to express a quadratic function. The mapping rule defines the transformations that have occurred to the base quadratic function \begin{align*}y=x^2\end{align*}
Yes, because the volume equals 2,000 and that equals 2
Answer:
2
Step-by-step explanation:
The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.
So we are going to need to corresponding y coordinates.
What y corresponds to x=1? y=3
What y corresponds to x=2? y=5
So we have the ordered pairs (1,3) and (2,5).
Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.
(2 , 5)
-(1 , 3)
-----------
1 2
The average rate of change is 2/1 or just 2.
Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.
Answer:
391 yds of material
Step-by-step explanation:
to find the answer, you take 136 yards divided by 8 blankets, which equals 17.
Next, you multiply 23 blankets by that 17.
Then you find your answer, 391 yds.
