It is shown that he goes down in a slower time than he does going up.
False, 24 x 10 x 90 = 21,600, 90 x 2,400 = 216,000
F should be -1, 6
E should be -4, 2
D should be -4, 9
Circles follow ghe equations
(x-h)^2 + (y-k)^2 =r^2
with center (h,k) and radius r
for this circle it would be
(x-7)^2 + (y-4)^2 = 100
Answer:
So the number of ways of choosing two distinct letters at a time is (42)=6. We can then add the duplicate pairs which are O,O and N,N to give a total of 8 possible pairs.
