The equation of the circle is in form (x - h)² + (y - k)² = r²

The center is (h,k) and r is the radius.

So the equation of the circle with the information given will be:

[ x - (-2.5)]² + [ y - (-4.4)]² = (7/4)²
(x + 2.5)² + (y + 4.4)² = (7/4)²

Hope this helps :)

Find the value of r in(4,r) (r,3) so that the slope of the line containing them is 0

Pavel [41]

Answer:

r = 3.

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope.

Finding the slope of a line, given two points:

When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.

Points (4,r), (r,3)

Change in y: 3 - r

Change in x: r - 4

Slope is 0, so:

$\frac{3 - r}{r - 4} = 0$

$3 - r = 0$

$r = 3$

The value is r = 3.

What is the HCF of 48 & 72

Masja [62]

Step-by-step explanation:

Factors of 72

= 2 x 36

= 2 x 2 x 18

= 2 x 2 x 2 x 9

= 2 x 2 x 2 x 3 x 3

Factors of 48

= 2 x 24

= 2 x 2 x 12

= 2 x 2 x 2 x 6

= 2 x 2 x 2 x 2 x 3

Common Factors = 2 x 2 x 2 x 3

HCF = 24

Ans : 24

I hope It's helpful!!
