Answer:
(x +6)^2 +(y -10)^2 = 225
Step-by-step explanation:
The standard form equation for a circle is ...
(x -h)^2 + (y -k)^2 = r^2
where the center is (h, k) and the radius is r.
The center of a circle is the midpoint of any diameter. The midpoint between two points is the average of their coordinates.
((-15, -2) +(3, 22))/2 = (-15+3, -2+22)/2 = (-6, 10)
The radius can be found using the distance formula, or by simply putting one of the given points in the equation for the circle to see what the constant (r^2) needs to be.
(x -(-6))^2 +(y -10)^2 = (-15-(-6))^2 +(-2-10)^2
(x +6)^2 +(y -10)^2 = 81 +144 = 225
The equation of the circle is ...
(x +6)^2 +(y -10)^2 = 225
Answer:
three and one fourth + 2x ≥ 6
Step-by-step explanation:
Let
x -----> the minimum number of hours he needs to practice on each of the two days
we know that
needs to spend at least seven hours each week practicing the drums
so
Convert mixed number to an improper fraction
substitute
Subtract 13/4 both sides
Divide by 2 both sides
therefore
The minimum number of hours he needs to practice on each of the two days is
my answer is in the image above
