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

<em></em>

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

Right triangle means:
sin, cos, and tangent

Here, we can see that:
sin 35° = \frac{x}{20}

Simplify.

20sin 35° = x

Multiply 20 by sin of 35 degrees.

x = 11.47(ROUNDED)

\frac{a}{b}

Where a and b are integers and b is not equal to 0.

The rational number 8.8 can be expressed as two integers. Like \frac{8.8}{1}
