X^2 + y^2 = 225
The radius is 15.
ANswer is C
The answer is 3√5. You use the distance formula: √((x2-x1)^2+(y2-y1)^2)
Answer:
x = -9
Step-by-step explanation:
4x+10=-26
Subtract 10 from each side
4x+10-10=-26-10
4x = -36
Divide each side by 4
4x/4 = -36/4
x = -9
Step-by-step explanation:
56,000÷7=8000
56,000÷70=800
56,000÷700=80
56,000÷7000=8
Remark
The diameter of the circle is AC. The hypotenuse of the right triangle is also AC. This assumes that A,B and C all lie on the circumference of the circle.
Answers
One
The center of the circle is on the diameter of the circle. In fact, the center bisects the diameter. So the center lies on AC and if the center is labeled O then AO = BO.
<em><u>Answer 1: </u></em> AC
Two
The answer is the single word diameter.
