Answer:
Step-by-step explanation:
The area will be increased by 4 times and volume will be increased by 8 times
Area of rectangular prism = 2 (lb+bh +hl)
When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)
= 4 * 2 (lb+bh +hl)
Volume of rectangular prism = lbh
When sides are doubled, Volume = 2l * 2h * 2b = 8 lbh
First, find the slope for the line. Choose any 2 points and note their coordinates. I'll take (0,4) and (2,10) as an example. Then you apply your formula, remembering each coordinate comes in the form of
.

The slope (
) is 3.
In this case, the slope represents the price per kilometer.
So, the fare is $3 per kilometer + the base fare, which is the value already present at 0km. According to the graph, when
,
.
Let's assume the following:
Price per Kilometer,
Base Fare,
Amount of Kilometers,
Total Cost
The total fare would be calculated by the following formula:

Using the given values:

In conclusion, the total cost for 6km is $22. Option A.

Answer:
what ???
Step-by-step explanation:
Using a graphing calculator, we can see the graph of the function y = x²-4x+1:
as we can see, the vertex of the function is (2,-3), and the solutions are (0.3,0) and (3.7,0)
