Allushta [10]

At the end of the third year the population of beetles will be 11,576beetles

<h3>Exponential equations</h3>

The standard form of an exponential function is given as:

y = ab^t

Given the following parameters

initial population 'a" = 10,000 beetles

Time = 3 years

rate b = 1.05

Substitute into the formula

y = 10,000(1.05)^3

y = 10,000(1.1576)
y = 11,576 beetles

Hence at the end of the third year the population of beetles will be 11,576beetles

Find the Product of (s^2+5s)(s^3+4s^2).

nikklg [1K]

The result of the product $(s^2+5s)(s^3+4s^2)$ is $s^5+9s^4+20s^3$

The product is given as:

$(s^2+5s)(s^3+4s^2)$

Rewrite as:

$(s^2+5s)(s^3+4s^2) = (s^2+5s) \times (s^3+4s^2)$

Expand the expression on the right-hand side

$(s^2+5s)(s^3+4s^2) = s^2\times (s^3+4s^2)+5s \times (s^3+4s^2)$

Distribute the expressions

$(s^2+5s)(s^3+4s^2) = s^5+4s^4+5s^4+20s^3$

Evaluate like terms

$(s^2+5s)(s^3+4s^2) = s^5+9s^4+20s^3$

Hence, the result of the product $(s^2+5s)(s^3+4s^2)$ is $s^5+9s^4+20s^3$
