Answer:
5a+13
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
they are complementary, they add to 90
Start with the equation of a circle whose center is at (h,k) and whose radius is r:
(x-h)^2 + (y-k)^2 = r^2
Substituting the given coordinates of the center:
(x-5)^2 + (y-[-5])^2 = r^2, or (x-5)^2 + (y+5)^2 = r^2
Substituding the given coordinates of a point (6,-2) on the circle:
(6-5)^2 + (-2+5)^2 = r^2
Simplifying:
1^2 + 3^2 = r^2, or 1 + 9 = r^2, or 10= r^2. Then r = sqrt(10).
14/15=28/30
1/2=15/30
28/30-15/30=13/30
the answer is 13/30 because you need to find the LCD(least common denominator) in order to minus，the LCD of 15 and 2 is 30 so you get 28/30 minus 15/30 and you get 13/30
Answer: the answer is 0.35 because
Square root of 546 is 23.3666428911
23.3666428911 divided by 67 is 0.34875586404
0.34875586404 rounded to 2 decimal points is 0.34875586404
