Note that the equation of the circle is
(x-h)² +(y-k)² =r²
where centre is (h,k)
the equation of the circle based on the information given
(x-3)² +(y-4)² =r²
and the point on the circle (3,-2)
substitute into the equation
(3-3)² +(-2-4)² =r²
r=6 or r=-6
since r is radius, we reject r=-6 since radius must be nonnegative.
the radius is 6
Answer:
$58.84375, rounded ≈ $58.84
Step-by-step explanation:
You can do 67.25 x 7/8 (use a calc if you are lazy) = 58.84375
I'm guessing you don't need to round so I'm going to add both real and rounded answers
Work:
2x+5(6x+23)=-13
2x+30x+115=-13
32x=-128
x=-4
y=6(-4)+23
y=-24+23
y=-1
The answer is (-4,-1)
Hopefully this helps!
Answer:
2/ 15
Step-by-step explanation:
since the probability is 16/ 120
then we simplify it till it gets 2/15
hope this helps
and good luck!
