It is possible that the proportion of adults in Country A equal to the proportion of adults in Country B. This statement does not necessarily mean that the populations of adults in the two countries are equal. It is the proportion and not the exact population. This occurs when the ratio of the population of adults to the total population of Country A is the same as that of the ratio of the population of adults to the total population of Country B.

a rectangular lawn has an area of a^3 - 125. use the difference of cubes to find out the dimensions of the rectangle.
ANEK [815]

The area of a rectangle is the product of its dimensions

The dimensions of the rectangle are: \mathbf{Length = a -5} and \mathbf{Width = a^2 + 5a + 25}

The area is given as:

\mathbf{Area = a^3 - 125}

Express 125 as 5^3

\mathbf{Area = a^3 - 5^3}

Apply difference of cubes

\mathbf{Area = (a - 5)(a^2 + 5a + 5^2)}

\mathbf{Area = (a - 5)(a^2 + 5a + 25)}

The area of a rectangle is:

\mathbf{Area = Length \times Width}

So, by comparison:

\mathbf{Length = a -5}

\mathbf{Width = a^2 + 5a + 25}

The table below represents a linear function f(x) and the equation represents a function g(x):
9966 [12]

Answer:

<u>Use 2 points from he table to find the slope of f(x):</u>

  • (0, -1) and (1, 7)

<u>The slope is:</u>

  • m = (7 - (-1))/1 = 8

The y - intercept is b = -1 according to point (0, -1).

<h3>Part A</h3>

<u>The lines are:</u>

  • f(x) = 8x - 1
  • g(x) = 3x - 2

The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.

<h3>Part B</h3>

See above
