10PTS PLEASE HELP!!!!!!!

Nostrana [21]

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - a coordinates of the center

r - a radius

A diameter d = 2r

We have

$x^2+(y-2)^2=100\to r^2=100\to r=\sqrt{100}\to r=10$

Answer: d = 2 · 10 = 20

What is the coefficient of the fourth term in the expansion of (x - y)^6?

Zarrin [17]

If you're aware of the binomial theorem, you have that:
 $(x-y)^6=\sum_{k=0}^{6}\binom{6}{6-k}x^k(-1)^{6-k}y^{6-k}$
$(x-y)^6=\sum_{k=0}^{6}\binom{6}{k}x^k(-1)^{k}y^{6-k}$

The fourth term is then the case $k=3$ , from which:
$c_{3}=\binom{6}{3}x^3(-1)^3y^3= \frac{6!}{3!(6-3)!} * (-x^3y^3)=- \frac{720}{36}x^3y^3=-20x^3y^3$
