Factorials greater than or equal to 10 ends in two zeros, which wont change the outcome

Add 1-9 factorials

1!+2!+3!+4!+5!+6!+7!+8!+9!=409113

The equation of a circle is (x+a)^2+(y+b)^2=r^2

(x+a)^2 is equal to x^2+2ax+a^2

(y+a)^2 is equal to y^2+2by+b^2

The radius is 6, so right side of the equation is 36

So X^2+2ax+a^2+y^2+2by+y^2=36

a is 5 since 2ax=10x

b is 8 bc 2by is 16y

Substituting we get (x+5)^2+(y+8)^2=36

Expanding we get x^2+10x+25+y^2+16y+64

Subtract 36 from both sides

x^2+10x+y^2+16y-k=0

25+64-36=53

-k=53

k=-53

If Hannah is 7 years older than him 2 years ago, then she is 5 Years older than him in the present. 

T is time age

T+5=2T

5=t

Tim is 5, and hannah is 10

So the ratio of sophomore being it versus a freshman being it is 3:2. That means if everyone has an equal chance to be president, the ratio of sophomore swimmers to freshman swimmers is 3:2. So 3/(3+2) is 3/5 of the team are sophomores.

48/4=12 12-5=7
