yeah-ya.... right?
Answer:
16= (x-4)^2 +(y+9)^2
Step-by-step explanation:
hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2
r= the radius (in your case you have the diameter so you do not need to square it)
(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)
a nice rating would help out
Question 15
This is an isosceles triangle, which means the base angles given are equal.
x^2 = 3x + 10
x^2 - 3x - 10 = 0
(x - 5)(x + 2) = 0
Set each factor to 0 and solve for x.
x - 5 = 0
x = 5
x + 2 = 0
x = - 2
Reject x = -2.
Angle D = 5^2 ir 25°.
Angle E = 3(5)+10 or 25°.
The total measure of the angles of any triangle is 180°.
So, angle F = 180° - 50°.
Angle F = 130°.
We have 2 green out of 1+2+3 = 6 total. So 2/6 = 1/3 is the probability of randomly selecting a green marble.
<h3>Answer: 1/3</h3>
