Answer:
The equation i.e. used to denote the population after x years is:
P(x) = 490(1 + 0.200 to the power of x
Step-by-step explanation:
This problem could be modeled with the help of a exponential function.
The exponential function is given by:
P(x) = ab to the power of x
where a is the initial value.
and b=1+r where r is the rate of increase or decrease.
Here the initial population of the animals are given by: 490
i.e. a=490
Also, the rate of increase is: 20%
i.e. r=20%
i.e. r=0.20
Hence, the population function i.e. the population of the animals after x years is:
P(x) = 490(1 + 0.200 to the power of x
1. 7x(x + 3)
7x(x) + 7(3)
7x² + 21
2. (7x + 1)(x + 3)
7x² + 21x + x + 3
7x² + 22x + 3
3. (x² + x)²
(x² + x)(x² + x)
x^4 + x³ + x³ + x²
x^4 + 2x³ + x²
For the first one its check box 1,3,5,and 6
An equation is marked out by the presence of the equality sign. From the calculation, the solution to the equation is x = 12/37.
<h3>What is equation?</h3>
The term equations refers to any mathematical statement that involves the equality sign.
Here we have the equation; 37x = 12, the first step is to divide both sides by 37 as shown;
37x/37 = 12/37
This leaves us with the result x = 12/37 which is the solution to the equation.
