an insect population grows at a rate of 25% per year.if its initial population is 4.2 million what will be its population in thr
marusya05 [52]

The population after 3 years would be 8.20 millions.

Step-by-step explanation:

Given,

Initial population = I = 4.2 million

Growing rate = r = 25%

If the initial population and growing rate is given, the formula to calculate the population (x) after n years would be:

x = I * (1 + \frac{r}{100} )^{n}

By putting the values in the equation, we get

x = 4.2 * (1 + \frac{25}{100} )^{n}

The population after 1st year (x1) would be

x1 = 4.2 * (1 + \frac{25}{100} )^{1}

x1 = 5.25 million

Similarly,

x2 = 4.2 * (1 + \frac{25}{100} )^{2}

x2 = 6.56 million

x3 = 4.2 * (1 + \frac{25}{100} )^{3}

x3 = 8.20 million

Hence, the population after 3 years would be 8.20 millions.

But, if you are asking about the total population at that time. It would be

I + x1 + x2 + x3 = 24.21 million

If the expression ax(2x + y - 5) simplifies to 6x² +3xy - 15x, what is the value of a?
nata0808 [166]
Since:
ax(2x + y - 5) = 6x^2 +3xy - 15x,

we should factor X out of the second equation to find out the value of a:
6x^2 + 3xy - 15x =
x(6x + 3y - 15),

Now that we factored X out, to find a, we need to find the other common factor:

(6x + 3y - 15) / (2x + y - 5),

which is 3.

Hence the value of a is 3
