Answer:

The answer to your question is We got the same. I think your work is correct.

Step-by-step explanation:

Data

height = 4x - 5

length = 3x + 1

width = 2x - 3

Formula

Volume of a rectangular prism = height x length x width

-Substitution

Volume = (4x - 5)(3x + 1) (2x - 3)

-Simplification

Volume = (12x² + 4x - 15x - 5)(2x - 3)

Volume = (12x² - 11x - 5)(2x - 3)

Volume = 24x³ - 22x² - 10x - 36x² + 33x + 15

Volume = 24x³ - 58x² + 23x + 15

2.- Number of computers N(t) = 5t + 106

Price of computers P(t) = 13t² + 25t + 600

Initial year = 2005

Final year = 2010

Number of years = 2010 - 2005

= 5 years

a) Calculate the numbers of computers

N(5) = 5(5) + 106

= 25 + 106

= 131 computers

b) Calculate the price

P(5) = 13(5)² - 25(5) + 600

= 13(25) - 125 + 600

= 325 - 125 + 600

= $800

c) Calculate the revenue

Revenue = 131 x $800

= $104880

If x= 0, 1, 2, and 3 and y=1, 1.5, 2, and 2.5, then what is the "y=" function?

mariarad [96]

The values are increasing equally so it's a linear function.
The formula is $y=mx+b$
For $x=0$ , $y=1$ so $b=1$ (y-intercept).
Take some point and put its coordinates into the equation to find $m$ (slope).
$2=m\cdot2+1\\
2m=1\\
m=\dfrac{1}{2}\\\\
\boxed{y=\dfrac{1}{2}x+1}$

What’s the answer??(SOMEONE PLEASE HELP ME)

Ket [755]

We know that :

If f(x) and g(x) are Two Functions Defined under same Domain, then Composite Function : (f o g)(x) = f(g(x))

Given : f(x) = $\frac{2}{x + 3}$ and g(x) = $\frac{1}{2x}$

⇒ (f o g)(x) = f(g(x))

⇒ $(f\;o\;g)(x) = f(\frac{1}{2x})$

⇒ $(f\;o\;g)(x) = \frac{2}{\frac{1}{2x} + 3} = \frac{4x}{1 + 6x}$

The Dade County Fair's admission fee is $8 and each ride costs $2.50. Sonia spent a total of $25.50. How many rides did she go o

Eva8 [605]

The answer to this question is 7. To solve this, start by subtracting 8 from 25.5, and you get 17.5. This is how much she has spent on rides. Now divide 17.5 by 2.5, and you get 7. I hope this helps!
