Answer:

x = - 2

Step-by-step explanation:

Givens

(2,5)

(x,3)

m = 1/2

Formula

m = (y2 - y1)/(x2 - x1)

Solution

y2 = 3

y1 = 5

x2 = x

x1 = 2

1/2 = (3 - 5)/(x - 2) Cross multiply

1*(x - 2) = 2 (-2) Combine and remove the brackets.

x - 2 = - 4 Add 2 to both sides

x = - 4 + 2

x = - 2

what is the circumference of a circle that has a radius of 8 units use 3.14 (pie) and round to the nearest hundredth

SashulF [63]

Remember that the formula for the circumference, $C$ , of a circle is:

$C = d \pi$

In this case, we are not given the diameter. However, remember that the diameter is equivalent to two times the radius of a circle. Thus,

$d = 2 \cdot 8 = 16$ ,

and we can say the circumference of our circle is:

$C = 16 \cdot 3.14 = 50.24 \,\textrm{units}$

The circumference of our circle is 50.24 units.

Also, a little side note not relating to the question:

Remember that $\pi$ is spelled as "pi" not "pie." Pie is a dessert, while pi is a mathematical constant.
