Determine any data values that are missing from the table, assuming that the data represent a linear function.

Stells [14]

Answer:

Fill in the blank with 14

Step-by-step explanation:

Given

The attached table

Required

Fill in the gap

Since, the table represents a linear function.

The first step is to calculate the slope of the table

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (1,2)$

$(x_2,y_2) = (2,6)$

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{6 - 2}{2 - 1}$

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

$m=4$

The equation of the table is calculated next as:

$y - y_1 = m(x - x_1)$

This becomes

$y - 2 = 4(x - 1)$

$y - 2 = 4x - 4$

Solve for y

$y = 4x - 4+2$

$y = 4x -2$

To fill in the blank;

The value of x is 4

So, substitute 4 for x in $y = 4x -2$

$y = 4 * 4 - 2$

$y = 16 - 2$

$y = 14$

Find the surface area of the cube.

Mrac [35]

<h3><u>Given</u>:-</h3>

$\rightarrow$ Side(a) of the cube = $\sf{\frac{1}{3}ft}$ .

$\rightarrow$ Surface Area of the cube with side $\sf{\frac{1}{3}ft.}$

<h3><u>Formula Used</u>:-</h3>

$\rightarrow$ Surface area of cube = $\sf{6a^2}$

<h3><u>Solution</u>:-</h3>

$\rightarrow$ Surface area of cube = $\sf{6a^2}$ (putting the value of a from the above given)

$\rightarrow$ $\sf{=\:6×(\frac{1}{3})^2}$

$\rightarrow$ $\sf{=\:6×\frac{1}{9}}$

$\rightarrow$ $\sf{=\:\frac{6}{9}}$

$\rightarrow$ $\sf{=\:\frac{2}{3}ft^2}$

Therefore, surface area of the given square = $\sf{=\:\frac{2}{3}ft^2}$
