Answer: After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.
Step-by-step explanation:
Since we have given that
Initial population 20 years ago = 10,000
Rate of growth = 8%
Number of years = 10+20 = 30 years
According to question, we will use "Compound interest":

Hence, After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.
Answer: Plane C (blue horizontal plane)
The points in question are marked in the diagram below. All you need are three points to define a plane.
The green vertical plane T contains point K, but not point X or point H.
Multiply them!! First multiply the numbers.

. But then, you have to multiply the variables. What is a times a equal to? Well, a times a is just a squared. Hence, the expression is equal to
C=p(t+30)
Let’s substitute in our values...
c=2(245+30)
Get the sum of what we have in parentheses...
c=2(275)
And finally
c=550
