Answer:
45
Step-by-step explanation:
Every 15 minutes, 30 kilometers are passed by.
15/60 = 1/4 hour
30/120 = 1/4 speed
The best answer here would be choice B
X^3 - x^2 - x + 1 = 0
Plug in x = 1:-
1 -1 - 1 + 1 = 2 - 2 = 0 so x =1 is a root.
If it has multiplicity 3 then the function will factor to (x - 1)^3:-
(x - 1)^3 = (x - 1)(x^2 - 2x + 1) = x^3 - 2x^2 + x - x^2 + 2x - 1
= x^3 - 3x^2 + 3x - 1 so it is FALSE
In 5 years the demand will be about $19.33 million.
<u>Given:</u>
The formula for compound growth is
, where <em>E</em> is ending value, <em>B</em> is beginning value, <em>R</em> is rate of growth, and <em>T</em> is the amount of time.
Demand for electrical services (<em>B</em>) = $12 million per year
Growth rate <em>(R) </em>= 10%
<em>T</em>= 5 years
<u>Computation</u>:
Substitute all values in the formula , we get
![E = 12 \times (1 + 0.1)^5\\\\=12(1.1)^5\\\\=12\times1.61051=19.32612\approx19.33](https://tex.z-dn.net/?f=E%20%3D%2012%20%5Ctimes%20%281%20%2B%200.1%29%5E5%5C%5C%5C%5C%3D12%281.1%29%5E5%5C%5C%5C%5C%3D12%5Ctimes1.61051%3D19.32612%5Capprox19.33)
In 5 years the demand will be about $19.33 million.
