The answer to the question is the third one I’m pretty sure
Answer: The equation of the circle is
Step-by-step explanation: We are given to write the equation of the circle with radius √13 units and center at the point (-9.3, 4.1).
We know that
the standard equation of a circle with radius r units and center at the point (h, k) is given by
In the given circle,
radius, r = √13 units and center, (h, k) = (-9.3, 4.1).
Therefore, the equation of the circle will be
Thus, the equation of the circle is
0.252x = 41
In Algebra, we must keep the equation balanced. What we do to one side, we must do to the other. We also need to isolate the variable x.
Since x is multiplied by 0.252, we must divide the left side by 0.252 to get rid of the 0.252. But, to keep the sides equal, we must do it to both sides.
0.252x/0.252 = 41/0.252
This leaves us with x = 162.69
Width of the rectangle is 10.67 ft
<u>Step-by-step explanation:</u>
Step 1:
Let the width of the rectangle be x. Then length = 2x + 12
Given width + length = 44ft ⇒ x + 2x + 12 = 44
⇒ 44 = 3x + 12
⇒ 32 = 3x
⇒ x = 32/3 = 10.67
Width of the rectangle = 10.67 ft
