it (6,18,23)
Step-by-step explanation:
Answer:
Step-by-step explanation:
We are going to apply algebra to solve for the exponential growth
we know that the expression for the exponential formula is
where
a = the amount before measuring growth or decay
= 10,000
r = growth or decay rate = 23%= 0.23
x = number of time intervals that have passed
since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)
hence the formula becomes
The expression that will give the population value is
3127^173 ≡ 7^173 mod 10
Now - let's look at the powers of 7 mod 10:
7^1 = 7 mod 10
7^2 = 49 ≡ 9 mod 10
7^3 ≡ 3 mod 10
7^4 ≡ 1 mod 10
And this cycle repeats. So
7^173 ≡ 7^1 ≡ 7 mod 10
The last digit is 7.
