The diameter of <u>circle A</u> is 4.8. The correct option is the second option- 4.8

<h3>Calculating the diameter of a circle </h3>

From the question, we are to determine the diameter of circle A

From the given information,

Circle A is dilated by a <u>scale factor</u> of 2.5 to form circle B

That is,

If the diameter of circle A is d, then the diameter of circle B will be 2.5d

Also, from the given information,

Diameter of circle B = 12

Then, we can write that

2.5d = 12

∴ d = 12/2.5

d = 4.8

Hence, the diameter of <u>circle A</u> is 4.8. The correct option is the second option- 4.8

Answer:

x=9

Step-by-step explanation:

Equation: 5.60x=50.40

Solve: 5.60x=50.40

Divide both sides by 5.60 ( 5.60x/5.60 ) and ( 50.40/5.60 )

what is the equation in point-slope form of the line passing through (0, 5) and (−2, 11)? (1 point) y − 5
makkiz [27]

According to the question, the line is through the points (0,5) and (-2,11)

To calculate the slope using standard formula that is :

m = \frac{(y(2)-y(1))}{(x(2)-x(1))} = \frac{(11-5)}{(-2-0)} =\frac{6}{-2} = -3

Now the slope equation will be: m(x(2)-x(1)) = (y(2)-y(1))

y-5 =(-3)(x-0) = y = -3(x)+5

The slope-intercept form is:y = -3x+5

What is the equation of the line?

To represent the set of points in an algebraic form is known as the equation of line. The set of points represent lines in the coordinate system. The parameters can be calculated and those parameters are slope and y-intercept.

To learn more about the equation of the line from the given link:
