We need to write an exponential function to model the situation, find each amount after the specified time. A population of 1,860,000 decreases 1.5% each year for 12 years.

Answer: The amount after the specified time is 155148.54.

Step-by-step explanation:

Since We have given that

Initial Population = 186000

Rate of decrement  = 1.5%

Time period = 12 years

Since we need to use "Exponential function ":

Amount=P(1-r)^t\\\\Amount=186000(1-\frac{1.5}{100})^{12}\\\\Amount=186000(1-0.015)^{12}\\\\Amount=186000(0.985)^{12}\\\\Amount=155148.54

Hence, the amount after the specified time is 155148.54.

Step-by-step explanation:

In propositional logic and Boolean algebra, De Morgan's laws are a pair of transformation rules that are both valid rules of inference. ... The rules allow the expression of conjunctions and disjunctions purely in terms of each other via negation.

An equation is shown below:
lisov135 [29]

Answer: x = 1

Step-by-step explanation:

5 ( 2x - 8 ) + 15 = -15 (write the equation)

5 ( 2x - 8 ) = -30 (subtract by 15 on both sides)

2x - 8 = -6 (divide by 5 on both sides)

2x = 2 (add 8 to both sides)

x = 1 (divide by 2 on both sides)
