The diameter of a circle has end points j(12,4) and k(-4,8)

Mathematics
1 answer:
alexdok [17]2 years ago
4 0

Answer:

diameter = 4√17;

radius = 2√17; and

center:  (4,6)

Step-by-step explanation:

The end points J (12,4) and K(-4,8) define the diameter of a circle, as well as the radius and center.  

Using the distance formula to find the diameter, d, we get:

d = √ ( (12+4)^2 + (4-8)^2 ) = √ ( 256 + 16 ), or √272 = √(8)(34)

                                         =  √(17)(2^4)) = 4√17

and the radius is half that, or 2√17.  The coordinates of the center can be found using the midpoint rule:  ( [12-4]/2, [4+8]/2 ), or (4, 6).

Finding the original price given the sale price and percent...
bulgar [2K]

Answer:

$325

Step-by-step explanation

78% is 234

x is 100%

cross multiply

\frac{234}{72} = \frac{x}{100}

234 × 100 = 72x

23400 = 72x

23400÷72 =72x ÷72

325 = x

Write an equation in slope-intercept form for each line.<br> (4,-1) and (-2,-1)
professor190 [17]

With each line, a slope-intercept relationship (4,-1) and (-2,-1).

Y = 0 ,X = 5.

<h3>What is slope-intercept form?</h3>

The slope-intercept form is just a means of stating a line's equation so that both the slope (steepness) as well as y-intercept (where another line crosses this same vertical y-axis) are obvious. This expression is frequently referred to as y = mx + b.

<h3>According to the given information:</h3>

To begin, are using the slope formula to figure out the average slope between two points here.

Let:

x1 = 4

y1 = -1

x2 = -2

y2 = -1

m = (y2-y1)/(x2-x1)

= (-1 - (-1))/ (4-(-1))

= 0/5

= 0

So the slope is 0.

We must now calculate the y-intercept. This will be accomplished by converting a single of the points and also the slope together into a point-slope linear equation. y2-y1 = m(x2-x1).

Let’s plug in the point (5,0).

So we get y-(-0) = (0/5)(x-(-5)) ⇒  y+0

= (0/5)x +  0 ⇒  y

So,

Y = 0

X = 5

with each line, a slope-intercept relationship (4,-1) and (-2,-1).

Y = 0 ,X = 5

Write in simplest form 3m⋅4⋅n⋅n<br><br><br>​
Sedbober [7]

Hello from MrBillDoesMath!

Answer:

12 m n^2

Discussion:

3m * 4 * n * n  =                       => 3* 4 = 12

12 m * n * n                              => as n*n = n^2

12 m n^2

Thank you,

MrB
