Answer:
B) (0,0); r=5
Step-by-step explanation:
A circle's standard form is (x-h)^2+(y-k)^2=r^2
The center is (h, k) and the radius is r.
So, here the center would be (0, 0) and the radius would be square root 25, or 5.
Answer:
c = √746
Step-by-step explanation:
You need to use Pythagorean Theorem (a² + b² = c²) in order to solve for the hypotenuse.
25² + 11² = c²
625 + 121 = c²
746 = c²
√746 = c
The metric table goes: millimeters, centimeters, decimeters, meters, dekameters, hectometers, kilometers. To move up the table, move the decimal point one to the left. To go from millimeters to centimeters, your answer would be 8,340,000.0, which is 8,340,000. However, you want kilometers. This would be 83.4 kilometers. Hope this helps!
Add the 7 and 4, which =11.
multiply times the 5, =55
and 20-55= -35
