In 2000, the total population of the U.S. was 281.4 million people. In 2010, it was 308.7 million people. What is the average ra
kifflom [539]

Answer:

2.73 million people per year

Step-by-step explanation:

Turn sentences into coordinates/points:

In 2000, 281.4 million people

  • (x₁, y₁) = (2000, 281.4)

In 2010, 308.7 million people

  • (x₂, y₂) = (2010, 308.7)

Rate of population per year:

\sf \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\rightarrow \sf \dfrac{308.7-281.4}{2010-2000}

\rightarrow \sf 2.73 \ million \ people

Yes, it is correct
alexgriva [62]

Answer:In Heather's solution to the problem, she wrote and solved an equation.

Her work is:

Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87

Solving like terms

1.08(x+15}=21.87

dividing both side by 1.08

we get

x+15=21.87/1.08

x+15=20.25

subtracting both side by 13.9198

x=20.25-15

x=5.25

According to correction

;

<u>Option 1st</u>

<u>yes,it is correct</u>

Rate of change of rational functions
densk [106]

Answer:

0.635

Step-by-step explanation:

rate~of~change = \dfrac{f(x_2) - f(x1)}{x_2 - x_1}

rate~of~change = \dfrac{f(x_2) - f(x1)}{x_2 - x_1}

x_1 = 0       x_2 = 0.3

f(x) = \dfrac{-7x^3}{x^4 - 1}

f(x_1) = f(0) = \dfrac{-7(0)^3}{(0)^4 - 1}

f(x_1) = \dfrac{0}{-1} = 0

f(x_2) = f(0.3) = \dfrac{-7(0.3)^3}{(0.3)^4 - 1}

f(x_2) = \dfrac{-0.189}{-0.9919} = 0.190543

rate~of~change = \dfrac{0.190543 - 0}{0.3 - 0} = 0.635
