Answer:
10
Step-by-step explanation:
The radius is the magnitude of the complex number that is the difference between any point on the circle and the center point. A suitable calculator can tell you that magnitude:
║(8+7i) - (2-i)║ = √((8-2)² +(7-(-1))²) = √(36+64) = √100 = 10
Answer:
Kindly refer to the attached images for the answer.
Step-by-step explanation:
Upper left coordinates of a rectangle are (-1, 4).
Upper right coordinates of the rectangle are (3, 4).
Perimeter of the rectangle = 24 units
Let A(-1, 4) and B(3, 4).
First of all, let us find the distance between the coordinates A and B.
Distance formula can be used to find the distance.
<em>Distance formula:</em>
<em></em><em></em>
Here, we have the following values:
When we will move from point B to C, we will move downwards on y axis for a distance of 8 units therefore value of coordinate will be same.
Therefore coordinates of C (3, 4-8) i.e. C (3, -4)
When we will move from C to D, the x coordinate will decrease for 4 units.
D (3-4, -4) i.e. D (-1, -4)
Kindly refer to the attached images for the answer.
Now,
