WC= 15 and CO = 17, what is OW?

soldier1979 [14.2K]

We know that triangle COW is a right triangle by the Tangent to a Circle Theorem.

So, we can use Pythagorean Theorem to find OW.

OW² + WC² = CO²

OW² + 15² = 17²

OW² + 225 = 289

OW² = 64

OW = 8

Find the midpoint of the segment below and enter its coordinates as an

Sati [7]

Answer:

(-1/2,5)

Step-by-step explanation:

Here is the complete question

Find the midpoint of the segment with endpoints of (1, 4) and (-2, 6) and enter its coordinates as an ordered pair. If necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.

Solution

The mid-point of a line is given by ((x₁ + x₂)/2,(y₁ + y₂)/2). From the question, x₁ = 1, y₁ = 4, x₂ = -2 and y₂ = 6. So,

((x₁ + x₂)/2,(y₁ + y₂)/2) = ((1 + (-2))/2,(4 + 6)/2)

= ((1 - 2)/2,10/2)

= (-1/2,10/2)

= (-1/2,5)

PLEASE HELP

2.

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

 $d = \sqrt{(3 - 1)^2 + (1 - 3)^2}$

 $d = \sqrt{(2)^2 + (2)^2}$

 $d = \sqrt{4 + 4}$

 $d = \sqrt{8}$

3.

$3y = -4x + 2$

$y = - \dfrac{4}{3} x + \dfrac{2}{3}$

Slope of line of given equation is -4/3.

Slope of perpendicular is -3/4.
