Answer:
In 50 years there'll be approximately 3582 elephants.
Step-by-step explanation:
If they are decreasing at a rate of 9% per year, it means it's population by year is:
population(0) = 400000
population(1) = population(0)*(100% - 9%) = population(0)*(91%)
population(2) = population(1)*(91%) = population(0)*(91%)*(91%) = population(0)*(91%)²
population(3) = population(2)*(91%) = population(0)*(91%)²*(91%) = population(0)*(91%)³
And so on, so the number of population as years passes is:
population(n) = population(0)*(91/100)^n
In this case we want to know the population of elephants when n = 50, so we have:
population(50) = 400000*(0.91)^50 = 3582.033
In 50 years there'll be approximately 3582 elephants.

Answer:
C. 111
Step-by-step explanation:
10^0 is 1 because of the exponent rule for 0 which is x^0 = 1, 10^1 would be just "10" and 10^2 would be "10x10" which is 100, adding these up would be 1 + 10 + 100 which equals 111
Answer:
53°
Step-by-step explanation:
b+37°=90°(being sum of angles of right angle)
or,b=90°-37°
or,b=53°
