This is an exponential function.
The starting population is: 10,000 and it doubles every 14 years.
In 42 years ( 42 : 14 = 3 ) the population doubles 3 times.
The equation ( exponential ) is :
y = 10,000 * 2^n
In this case: n = 3
y = 10,000 * 2 ^3 = 10,000 * 8 = 80,000
Answer: In 42 years the population of this town will be 80,000.
Answer:
You didn't list the answers but it's 43.98 so close to 44 I'm guessing

Answer:
5, 3
Step-by-step explanation:
1,-1 enlarged by 4
New coordinates = 4 + 1 = 5
-1 + 4 = 3
Answer:
$24.375
Step-by-step explanation:
Regular price of sandals = $32.50
Store sells sandals for 25% of the regular price.
Hence selling price =(100-25)% of the regular price.
In other words, selling price = 75% of regular price
= 75% of $32.50
=
=
Hence the sale price of the sandals is $24.375
This is $8.125 less than the regular price of the sandal.
