Answer:C) x2 + y2 =45
Step-by-step explanation:
The equation of a circle in standard form is (x-h)2+(y-k)2=r2.
Since you know the center is (0,0), you can sub this is value in for h and k, then use the point (3,6) to sub in for x and y and you will find r2 =45. Hope that helps :)
Answer:
x = 9, ∠ 1 = ∠ 2 = 66°
Step-by-step explanation:
If r and s are parallel then
∠ 1 = ∠ 2 ( corresponding angles ) , then
84 - 2x = 93 - 3x ( add 3x to both sides )
84 + x = 93 ( subtract 84 from both sides )
x = 9
Then
∠ 1 = 84 - 2x = 84 - 2(9) = 84 - 18 = 66°
∠ 2 = 93 - 3x = 93 - 3(9) = 93 - 27 = 66°
Answer:
yes
Step-by-step explanation:
The price of Stock A at 9 A.M. was $14.72. Since then, the price has been increasing at the rate of $0.06 each hour. At noon the price of Stock B was $15.22. It begins to decrease at the rate of $0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
The correct answer is 180 degrees. Hope this helps!!!!
