Write the equation of the circle with center (−1, −3) and (−7, −5) a point on the circle.
Pepsi [2]
So, we know the center is at -1, -3, hmmm what's the radius anyway?

well, the radius will be the distance from the center to any point on the circle, it just so happen that we know -7, -5 is on it, thus

\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ -1 &,& -3~) 
%  (c,d)
&&(~ -7 &,& -5~)
\end{array}
\\\\\\
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
r=\sqrt{[-7-(-1)]^2+[-5-(-3)]^2}\implies r=\sqrt{(-7+1)^2+(-5+3)^2}
\\\\\\
r=\sqrt{36+4}\implies r=\sqrt{40}\\\\
-------------------------------

\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{-1}{ h},\stackrel{-3}{ k})\qquad \qquad 
radius=\stackrel{\sqrt{40}}{ r}
\\\\\\\
[x-(-1)]^2+[y-(-3)]^2=(\sqrt{40})^2\implies (x+1)^2+(y+3)^2=40

How many times greater is the value of the 5 in 503 than the value of the 5 in 53?
disa [49]

Answer:

10 times greater

Step-by-step explanation:

Because value of 5 in 503 is 5*100

Then the value of 5 in 53 is 5*10

So then value of 5 in 503 is 10 times greater than the value of 5 in 53

I hope this helps

Which polynomial correctly combines the like terms and expresses the given polynomial in standard form?
Lera25 [3.4K]

Answer:

The first option

Step-by-step explaination:

9 {xy}^{3}  - 4 {y}^{4}  - 10 {x}^{2}  {y}^{2}  +  {x}^{3} y +  {3x}^{4}  +  {2x}^{2}  {y}^{2}  - 9 {y}^{4}

(- 4 {y}^{4} - 9 {y}^{4} )   + (  - 10 {x}^{2}  {y}^{2} + {2x}^{2}  {y}^{2}) + 9 {xy}^{3}+  {x}^{3} y +  {3x}^{4}

- 13 {y}^{4}  - 8 {x}^{2}  {y}^{2}  + 9 {xy}^{3}  + x {}^{3} y + 3x {}^{4}

- 13 {y}^{4}  +  {3x}^{4}  - 8 {x}^{2}  {y}^{2}  +  {x}^{3} y +  {9xy}^{3}
