Find the center of a circle whose end points of a diameter are A (-5,6) and B (3,4)

victus00 [196]

Answer:

(-1, 5)

Step-by-step explanation:

The center of a circle is the midpoint of the diameter.

So we have to calculate the midpoint of the diameter, using this formula:

midpoint = ( $\frac{x_{2 }+x_{1} }{2}$ , $\frac{y_{2} + y_{1} }{2}$ )

= ( $\frac{3 + (-5)}{2}$ , $\frac{4 + 6}{2}$ )

= (-1, 5)

∴ The center of the circle lies at the point (-1, 5).

Find the measure of angle R 101° 39° R

ivanzaharov [21]

Answer:

m<R = 31°

Step-by-step explanation:

Arc QT = 39°

Arc PV = 101°

m<R = ½(arc PV - arc QT) => secant-secant exterior angle measure theorem

m<R = ½(101 - 39)

m<R = ½(62°)

m<R = 31°

What is the slope of this line? Please help someone, anyone.

Sphinxa [80]

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Where:

$(x_ {1}, y_ {1})$ and $(x_ {2}, y_ {2})$ are two points through which the line passes.

According to the figure we have to, the line goes through:

$(x_ {1}, y_ {1}) :( 0, -2)\\(x_ {2}, y_ {2}): (- 2,0)$

Substituting we have:

$m = \frac {0 - (- 2)} {- 2-0} = \frac {0 + 2} {- 2} = \frac {2} {- 2} = - 1$

Thus, the slope of the line is -1.

Answer:

$m = -1$
