What is the equation of a circle with center (-3,-5) and radius 4?
kobusy [5.1K]

Answer:   D) (x + 3)² + (y + 5)²  = 16

<u>Step-by-step explanation:</u>

The equation of a circle is: (x - h)² + (y - k)² = r²    

where (h, k) = center   and    r = radius

Given: (h, k) = (-3, -5)  r = 4

Equation: (x - (-3))² + (y - (-5))² = 4²

                 (x + 3)²  +  (y + 5)²  = 16

I need help urgent plz someone help me solved this problem! Can someone plz help I’m giving you 10 points! I need help plz help
poizon [28]

Answer: Delete the point (0, 4)

<u>Step-by-step explanation:</u>

Your line for y = (1/3)x + 4 is correct.

                             m=1/3   b=4

Start at (0, 4) and draw a line through a point up 1 and 3 to the right (3, 5).

Your line for x = 6 is correct.

A vertical line through (6, 0), (6, 1), (6, 2), ...

Your point for (6, 6) is correct.

                    x=6, y=6

Your error is that you used the dot tool to plot a point for (0, 4). You DO need this point to create the line y = (1/3)x + 4, however the instructions do not state to mark this coordinate with a dot.

Answer:

V = pi * R^2 * h

R = (V / (pi * h))^1/2 = (141.3 / (3.14 * 5))^1/2 = 3 cm

The graph shows a reflection in the x-axis. The matrix M such that, for any point (x, y), M(x, y) = (x', y') is
Rashid [163]

Answer:

This is a reflection about the x-axis.


Step-by-step explanation:

A reflection about the x-axis has the rule

[x,y]-> [x,-y].

Therefore

M[x,y] = [x,-y}

Let M=

|a  b|

|c  d|

Then the matrix multiplication gives

ax+by=x.............(1)

cx+dy=-y............(2)

Solving the previous equations (1) and (2) gives

a=1, b=0

c=0, d=-1

giving M as

|1  0|

|0 -1|
