The points on the circumference are (3, 5), (3, -9), (8, -2 + √24) and (8, -2 - √24))

<h3>How to determine the points on the circumference of the circle?</h3>

The circle equation is given as:

(x-3)^2 +(y+2)^2= 49

Rewrite as:

(y+2)^2= 49 -(x-3)^2

Take the square root of both sides

y+2= ±√[49 -(x-3)^2]

Subtract 2 from both sides

y = -2 ± √[49 -(x-3)^2]

Next, we determine the points

Set x = 3

y = -2 ± √[49 -(3-3)^2]

Evaluate

y = -2 ± 7

Solve

y = 5 and y = -9

So, we have

(x, y) = (3, 5) and (3, -9)

Set x = 8

y = -2 ± √[49 -(8-3)^2]

Evaluate

y = -2 ± √24

Solve

y = -2 - √24 and y = -2 + √24

So, we have

(x, y) = (8, -2 + √24) and (8, -2 - √24)

Hence, the points on the circumference are (3, 5), (3, -9), (8, -2 + √24) and (8, -2 - √24)

XY = 12

Step-by-step explanation:

15/20 = 12/SY

15SY = 240

SY = 16

15/20 = 9/XY

15XY = 180

XY = 12

3-2i+8=23 can you solve this find what i equals
sasho [114]

Answer:

i = -6

Step-by-step explanation:

3 - 2i + 8 = 23

3 + 8 - 2i = 23

11 - 2i = 23

11 - 11 - 2i = 23 - 11

-2i = 12

-2i ÷ -2 = 12 ÷ -2

i = -6

If y varies directly as x, what happens to x if y increases?
Aliun [14]

Answer:

Hi! If y varies directly as x, then k=y/x. If this is the case then, as y increases, x should increase also by the same factor.

Step-by-step explanation:

1. y varies directly as x: k=y/x or y=x*k; K is the constant or the factor that dictates the increase or decrease of y or x.

Hopefully that makes since! There is a good article on SparkNotes that explains this concept better I think.
