Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.

For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
Let's solve your equation step by step.
5(k - 2) - 8k= -34
Step 1: Simplify both sides of the equation.
5(k - 2) - 8k= -34
(5)(k) = (5)(-2) + - 8k= -34 (Distribute)
5k + -10 + -8k = -34
(5k + -8k) + (-10) = -34 (Combine Like Terms)
-3k + -10 = -34
-3k - 10 = -34
Step 2: Add 10 to both sides.
-3k - 10 + 10 = -34 + 10
-3k = -24
Step 3: Divide both sides by -3.
-3k\3 =-24\-3

Step-by-step explanation:
Answer:
Sometimes
Step-by-step explanation:
I’ll give you an example so you can understand:
Let’s say x is 4. So plug 4 into the problem:
|4|=4 → This is a very true statement, where the absolute value of 4 is equal to 4.
Now, let’s say x is -7. So plug -7 into the problem:
|-7|=-7 → This is a false statement because it’s saying that the absolute value of -7 is -7 which is very untrue.
So |x|=x only works for positive numbers, but not negative numbers. Therefore, |x|=x is the absolute value of x <u>sometimes.</u>
