that makes the equation of the line perpendicular to it to be -1 / (1/6) = -6

the general equation in point slope form is

y-y1 = m(x-x1) where m=slope and (x1,y1) = point on the line

so here we have:-

y - 23 = 6(x -(-3)

y - 23 = 6x + 18

y = 6x + 41

thats the answer

Consider circle H below.

hram777 [196]

We have been given a circle H, in which length of arc XY is 78 miles and measure of arc XY is 70 degrees. We are asked to find the radius of circle.

We will use arc length formula to solve our given problem.

$\text{Arc length}=2\pi r\cdot \frac{\theta}{360^{\circ}}$ , where,

r = Radius of circle,

$\theta$ = Central angle corresponding to arc.

We know that the measure of central angle that corresponds to arc XY will be equal to measure of arc XY.

$78=2\cdot 3.14\cdot r\cdot \frac{70^{\circ}}{360^{\circ}}$

$78=2\cdot 3.14\cdot r\cdot \frac{7}{36}$

$78= 3.14\cdot r\cdot \frac{7}{18}$

$78= r\cdot \frac{21.98}{18}$

$r\cdot \frac{21.98}{18}=78$

$r\cdot \frac{21.98}{18}\cdot \frac{18}{21.98}=78\cdot \frac{18}{21.98}$

$r=63.8762511373$

Upon rounding to nearest hundredth, we will get:

$r\approx 63.88$

Therefore, the radius of circle H is approximately 63.88 miles.
