<h3>Answer with explanation:</h3>
It is given that:
Circle 1 has center (−4, −7) and a radius of 12 cm.
Circle 2 has center (3, 4) and a radius of 15 cm.
Two circles are said to be similar if by some translation and dilation it could be placed over the other to form the same circle.
The circles are similar because the transformation rule ( x,y ) → (x+7,y+11) can be applied to Circle 1 and then dilate it using a scale factor of 5/4
( Since, as the center of circle 1 is (-4,-7)
so,
(-4+7,-7+11) → (3,4)
( Since, the radius of circle 1 is 12 and that of circle 2 is 15 cm.
so, let the scale factor be k .
that means :
)

Step-by-step explanation:
<h3> The missing question is: "What is the Functions formula A(t)=?"</h3><h2 />The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
According to the data given in the exercise, you know that:
- represents the area to paint the Hiros' romm as a function of time.
- The rate he painted the room was 8 square meters per hour.
- The area left to paint after 3 hours was 28 m².
Therefore, based on this, you can idenfity that:
1. The slope of the line is:
2. One of the point on the line is:
So you must substitute the slope and the coordinates of that point into and then solve for "b" in order to find its value:
Therefore, you can determine that the function is:
