In 2018, the population of a district was 25,000. With a continuous annual growth rate of approximately 4%, what will the

const2013 [10]

Answer:

<h2>40,000 populations</h2>

Step-by-step explanation:

Initial population in 2018 = 25,000

Annual growth rate (in %) = 4%

Yearly Increment in population = 4% of 25000

= 4/100 * 25000

= 250*4

= 1000

This means that the population increases by 1000 on yearly basis.

To determine what the population will be in 2033, we need to first know the amount of years we have between 2018 and 2033.

Amount of years we have between 2018 and 2033 = 2033-2018

= 15 years

<em>After 15 years, the population will have increased by 15*1000 i.e 15,000 more than the initial population.</em>

<em />

<em>Hence the population in 2033 will be Initial population + Increment after 15years = 25,000+15000 = 40,000 population.</em>

If sinx=1/5 and x terminates in the first quadrant, determine cos 2x.

LenaWriter [7]

Hey there! I'm happy to help!

Let's think of this angle being put inside of a unit circle (a circle with a radius of one). This angle is going to stay inside the first quadrant, so all of its trigonometric ratios will be positive.

We are given that the sin of x is 1/5. To get the x by itself, we can just find the inverse sine of both sides to isolate the x.

x=sin $^-1$ (1/5)

x≈ 11.536959

2x≈ 23.073918

Now, we just cosine this value.

cos2x≈ 0.92

I hope that this helps! Have a wonderful day!
