X would be 4! Since there is a right angle the two sides making the right angle are even!
Answer:
Total students that failed in both subjects would be 10
Step-by-step explanation:
Students that passed English : 70 - 40 = 30
Students that passed Hindi : 80 - 40 = 40
Total students that passed both subjects 110 (40 + 40 + 30)
120 - 110 = 10 students failed in both subjects
The 30 & 40 come from the students that passed each subject above, then the extra 40 comes from the amount of students that passed both.
Answer:
A,C
Step-by-step explanation:
Answer:
A.
(x - 5)^2 + (y + 8)^2 = 4
Step-by-step explanation:
The equation for a circle in center radius form is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We need to determine the radius, from the two points which is the distance
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (5-5)^2+( -8--6)^2)
= sqrt(0+ (-8+6)^2)
= sqrt( 0+(-2)^2)
= sqrt(4)
= 2
The radius is 2 and the center is (5,-8)
(x-5)^2 + (y--8)^2 = 2^2
(x-5)^2 + (y+8)^2 = 4
