Collect the like terms
So 3n-n=2n and -1+4=3
(3n-1)+(4-n)=2n+3
Answer:
Step-by-step explanation:
<u>Exponential function is:</u>
<u>If we consider the time difference in years as x and the initial population as a, then we get:</u>
<u>Find the value of b:</u>
- b¹⁰ = 675647/617594
- b¹⁰ = 1.09399864636
- b = 1.09399864636^(1/10)
- b = 1.009 (rounded)
<u>The equation we got is:</u>
Here we have y- population after x years since 2010, x - the number of years since 2010 and 1.009 is the population growth rate.
Answer: 3.83m^3
Step-by-step explanation:
Use formula for volume of a triangular prism (Area of triangle times length of the figure)
If you would like to cube one number and make it bigger than 200 but smaller than 400, you can find the number using the following steps:
n ... the number
200 < n^3 < 400
For example:
If n equals to 6, then n^3 = 6^3 = 6 * 6 * 6 = 216 and 200 < 216 < 400, so the result could be 6.
If n equals to 7, then n^3 = 7^3 = 7 * 7 * 7 = 343 and 200 < 343 < 400, so the result could also be 7.
But, if n is 8, then n^3 = 8^3 = 8 * 8 * 8 = 512 and 512 > 400.
Result: You can take the numbers 6 and 7.
