One of the equations for a circle is (x - h)² + (y - k)² = r² where (h, k) are the center and r is the radius.
So after substitution:
(x + 6)² + (y - 2)² = 100
Notice the equation has the opposite of h and k and 100 is the result of squaring 10.
Answer:
The angular speed of a point on Earth is
π12
radian per hour. The Equator lies on a circle of radius approximately 4000 miles. Find the linear velocity, in miles per hour, of a point on the Equator.

Answer:
C
Step-by-step explanation:
At most he cannot spend 36 dollars so 36/1.8=20 but he cannot spend more than 35.99 so it is C
Answer:
3 1/4
Step-by-step explanation:
3/4 + (1/3 divided by 1/6) - (- 1/2)
first calculate between the brackets.
(1/3) / (1/6)
Division is the inverse of multiplying.
(1/3) * (6/1)
multiply both numerators and multiply both denominators
1*6 / 3*1 = 6/3 = 2
3/4 + (2) - (- 1/2)
make all denominators into 4
3/4 + (8/4) - (- 2/4)
- ( - = plus
3/4 + (8/4) + 2/4
3/4 + 8/4 + 2/4
add all numerators since the denominators are all the same.
( 3 + 8 + 2 ) / 4
13/4
3 1/4
3.25
