F(x)=5x^3-2x^2+3
=5 2^3 - 2 2^2 +3
=5 (8) - 2 (4) +3
= 40 - 8 + 3
= 35
answer is A.35
Answer:
The volume is 45 cubic units.
So enter "45" into the box.
Step-by-step explanation:
Multiply the dimensions to get the volume. (<u>Length times width times height</u>)
The box is 5 units by 3 units by 3 units.
Solve 5x3x3 (LxWxH) using a calculator...
And you get 45 cubic units.
4. Just look at the graph, and see which coordinates are on the line.
D, E, and F are on the line.
5. The y-coordinate is <em>(0,4)</em>, and the slope is (4 + 8)/(0 - 4) = <em>-3</em>. Therefore, the equation of the line is <em>y = -3x + 4</em>. Plugging in the numbers we know gives us <em>b = -3*8 + 4</em>. b = -20.
6. Find the number of times P is on a line. There are two lines that do so.
If you make yourself a monthly expense chart:
Months
<u> 1 2 3 4 5 6 7 8 9 10</u>
Opt 1 -80 -30 -30 -30 -30 -30 -30 -30 -30 -30
Opt 2 -40 -40 -40 -40 -40 -40 -40 -40 -40 -40
By month 5 the total amount spent for Opt 1 is $200 and Opt 2 is $200
For part two add up the values for each all the way up to month 9.
Option 1: 80 + 30(8) = 80 + 240 = 320 spent
Option 2: 40(9) = 360 spent
So option 1 is cheaper by month 9
