A country's population in 1994 was 140 million. In 1998 it was 146 million. Estimate the population in 2011 using the exponentia

serious [3.7K]

Answer:

Estimated To Be 167 Million

Step-by-step explanation:

The exponential growth formula is given by

where: P is the population of the country, t years after the initial year (i.e. in this case, 1994). is the initial population of the country (i.e. the population of the country in 1994).

r is the growth rate of the population and

t s the number of years after the initial year.

We obtain the value of r by comparing the growth between 1994 and 1998.

Here: P = 146, , and t = 4 years

Thus To estimate the population of the country in 2011, we note that 2011 is 17 years after 1994.

Thus, the population of the country in 2011 can be estimated to be

million

Therefore, the population of the country in 2011 can be estimated to be 167 million to the nearest million

My name is Ann [436]

(1) The train travels 4 miles per gallon.

(2) The slope of the graph is $m=\frac{1}{4}$

Explanation:

(1) The miles that train travels per gallon is given by

$Miles= \frac{800}{200}$

Dividing, we have,

$Miles= 4$

Thus, the train travels 4 miles per gallon.

(2) To determine the slope, let us consider two points from the graph.

The coordinates are $(0,0)$ and $(800,200)$

Thus, substituting the coordinates in the slope formula, we get,

$m=\frac{200-0}{800-0}$

Simplifying, we have,

$m=\frac{200}{800} =\frac{1}{4}$

Thus, the slope of the graph is $m=\frac{1}{4}$

tankabanditka [31]

Answer:

You should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.

Step-by-step explanation:

With the information provided about the recipe, you can use a rule of three to find the cups of pineapple you should use if you only have 1 cup of orange juice given that the recipe calls for 30 cups of orange juice and 18 cups of pineapple juice:

30 cups of orange juice → 18 cups of pineapple juice

1 cup of orange juice → x

x=(1*18)/30=0.6 cups of pineapple juice

According to this, the answer is that you should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.
