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
5 /. 3/5 =. 5x5 / 3 = 25/3
Answer:
A. (x · 60) + (x · 5)
Step-by-step explanation:
<h3>
Answer is -28</h3>
==================================================
Work Shown:
T(2) = 20 means the second term is 20
T(1) = 26 because we go backwards from what the rule says (subtract 6) to step back one term. Going forward, 26-6 = 20.
Since a = 26 is the first term and d = -6 is the common difference, the nth term is
T(n) = a + d*(n-1)
T(n) = 26 + (-6)(n-1)
T(n) = 26 - 6n + 6
T(n) = -6n + 32
Plugging n = 1 into the equation above leads to T(1) = 26. Using n = 2 leads to T(2) = 20.
Plug in n = 10 to find the tenth term
T(n) = -6n + 32
T(10) = -6(10) + 32
T(10) = -60+32
T(10) = -28
