The table below shows some values that satisfy a linear function.

Makovka662 [10]

Answer:

1.5

Step-by-step explanation:

Given the pair of points on the table.

Now the formula for slope, $m=\dfrac{y_2-y_1}{x_2-x_1}$

To calculate the slope we only require two pair of points.

Let us take: $(x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)$

$m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5$

The slope of the linear function represented by the values in the table is 1.5.

Note: You can use any two set of values. The result will be the same.

The radius of a circle is 16 millimeters. What is the circle's area?

Kisachek [45]

Answer:

803.84 millimeters²

Step-by-step explanation:

How do we find the area of a circle?

The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.

<u>Solving</u>

<u></u> $3.14 *16^2$
$3.14*256$
$803.84$

Therefore, the area is 803.84 square millimeters.

DochEvi [55]

${a}^{2} + {b}^{2} = {c}^{2} \\ {8}^{2} + {5}^{2} = {c}^{2} \\ 64 + 25 = {c}^{2} \\ 89 = {c}^{2} \\ \sqrt{89} = {c}^{2} \\ 9.4 = c$
