Step-by-step explanation:

A=⎣⎢⎢⎡324−21−33−12⎦⎥⎥⎤,x=⎣⎢⎢⎡xyz⎦⎥⎥⎤,B=⎣⎢⎢⎡814⎦⎥⎥⎤

∣A∣=⎣⎢⎢⎡324−21−33−12⎦⎥⎥⎤

=3[1−3−12]−1(−2)[24−12]+3[241−3]⇒3(2−3)−2(4+4)+

Answer:

Step-by-step explanation:

Remark

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary. x is opposite 112 degrees. Therefore x and 112 add up to 180 degrees.

Formula

x + 112 = 180                      Subtract 112 from both sides.

Solution

x + 112-112 = 180 - 112

x = 68

Answer

x = 68

The center is at (0,0) so the equation will be like

x^2 + y^2 = r^2      where r = radius of the circle.

from the diagram you can see that r = 4

answer is x^2 + y^2 = 16

How do you find the equation that is perpendicular to 2x-5y=20, passing through the point (7,-8)?
IrinaK [193]
To find a perpendicular line you first need to see the equation in slope intercept form. To do that you need to solve for y. 

2x - 5y = 20 ---> subtract 2x from both sides
-5y = -2x + 20 ---> divide by -5
y = 2/5x - 4

Now that you have this, note that a perpendicular line has opposite and reciprocal slope. Since the slope in our equation is 2/5, that means the new line will have -5/2 slope. So we use the point given and the slope to find the y intercept. 

y = mx + b
-8 = -5/2(7) + b ---> multiply
-8 = -35/2 + b ---> add 35/2 to both sides
19/2 = b

Now use our new slope and new y intercept to write the new equation. 

y = -5/2x + 19/2
