Answer:
x^3 - x^2 - 6x
Step-by-step explanation:
First, add f +g
x^2 + 1 + 5 -x (combine like terms)
x^2 - x +6
Next, multiply the new equation by x
x(x^2 - x + 6) Use distributive property
= x^3 - x^2 + 6x
Answer:
8.4 miles a minute
Step-by-step explanation:
42÷5 = 8.4 a minute
The equation for exponential decay is given as y = a(1 - r)^x.
<u>Explanation:</u>
The formula for original exponential decay is y = ab^x.
The growth rate (r) is determined as b = 1 + r.
The decay rate (r) is determined as b = 1 - r.
y = ab^x (Where b = 1 - r)
y = a(1-r)^x
a represents the initial value
r represents growth or decay rate
x represents the number of time intervals that have passed.
<em>For example</em>
The population of Home Town is 2016 was estimated to be 35,000 people with an annual rate of increase of 2.4%.
The equation for decay factor y = 35000(1 - 0.024)^x
y = 35000(0.976). (where x = 1)
Multiply all 4 by each other.
