Answer:
(g - f)(x) = 3x - 6
Step-by-step explanation:
Step 1: Define
f(x) = 5 - x
g(x) = 2x - 1
Step 2: Find (g - f)(x)
(g - f)(x) = 2x - 1 - (5 - x)
(g - f)(x) = 2x - 1 - 5 + x
(g - f)(x) = 3x - 6
Answer:
Step-by-step explanation:
When you're working with 10, 100, 1000, just move the decimal the corresponding number of zeros. Then put the original number.
9/10000=0.00009
^ ^ ^ ^ ^ ^ ^ ^
If your multiplying, move the decimal the other way.
The answer to your question is $0.07 or 7 cents.
The correct answer is B) y=80000(1.03)ˣ.
Population growth is represented using an exponential equation. These equations are of the form
y = a(1+r)ˣ, where y is the total population, a is the initial population, r is the growth rate, and x is the amount of time.
We first find the growth rate. This is the percent of change, which is found by
amount of change/original amount
The amount of change from 2010 to 2011 is 82400-80000=2400. 2400/80000 = 0.03, so r = 0.03.
The growth rate from 2011 to 2012 is (84872-82400)/82400 = 0.03. Checking the others, they are very close to this as well, so we will use this as r.
Our value of a in the equation is the initial population, 80000. This gives us:
y = 80000(1+0.03)ˣ = 80000(1.03)ˣ
