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

HOW DOES SIMILARITY DIFFER FROM CONGRUENCE? WHY DOES THE PROPERTY OF RIGID MOTION NOT APPLY FOR ALL TRANSFORMATIONS?
Elan Coil [88]

Answer:

Similarity means that two figures are the same shape, but not necessarily the same size, color or orientation, congruent means two figures are the same in every form.

Step-by-step explanation:

In my understanding, The Property of Rigid motion holds two points:

- The relative distance between two points stays the same,

- The relative position of the points stays the same

This includes, translations, reflections, and rotation but not to dilutions since it breaks these rules. The relative distance between points gets smaller after dilution.
