Answer:

r=\frac{ln(1.5)}{4}

Explanation:

Given:

Total population after time (P) = 100% + 50%  = 1 + 0.5 = 1.5

Starting population (p) = 100% = 1

Number of year (t) = 4 year

rate of growth = r

Computation:

Exponential growth function for population :

P = pe^{rt}

1.5 = 1\times e^{4\times r}

1.5 = e^{4r}

From taking log:

4r = ln(1.5)

r=\frac{ln(1.5)}{4}

Neporo4naja [7]

Answer: 26.5% increase

Explanation:

Current profit = Sales - Variable costs - fixed costs

= ((32.50 - 16.50) * 360 bears) - 1,420

= $4,340

Sales increase by 20% = 360 * ( 1 + 20%) = 432 bears

New profit;

= ((32.50 - 16.50) * 432 bears) - 1,420

= $5,492

Effect of sales increase = ( 5,492 - 4,340) / 4,340

= 26.5% increase

Automatic stabilizers refer to:
Aliun [14]

Answer:

B) government spending and taxes that automatically increase or decrease along with the business cycle.

Explanation:

The two most common automatic stabilizers are: income taxes and unemployment benefits.

When the economy is strong, people make more money, and income tax revenue automatically increases.

On the contrary, when the economy is weak, or in recession, people earn less, and more of them are unemployed. Unemployment benefits therefore increase accordingly.

Guy​ Ferrell, a student who lives in the country​ Paragon, observes that analysts are cutting their growth forecasts for the eco
Rama09 [41]

The correct answer to this open question is the following.

The statement, if​ true, that would explain the​ analysts' predictions would be "the Producer Price Index has been steadily increasing over the past few months."

That is what would have been the factor that supports the forecast. Although inflation has been constant at low levels, what changed was the Producer Price Index that is moving up. This factor could modify the results despite inflation is stable at this moment. When inflation is high, it directly affects the price of goods and the consumer.
