What's the center of a circle whose equation is (x – 14)2 + (y + 21)2 = 64?
kvasek [131]

Answer:

The center of the circle is:

  • \left(a,\:b\right)=\left(14,\:-21\right)

Thus, option (2) is true.

Step-by-step explanation:

The circle equation is given by

\left(x-a\right)^2+\left(y-b\right)^2=r^2

here,

  • r =  raduis
  • center = (a, b)

Given the equation

\left(x-14\right)^2+\left(y+21\right)^2=64

\mathrm{Rewrite}\:\left(x-14\right)^2+\left(y+21\right)^2=64\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}

\left(x-14\right)^2+\left(y-\left(-21\right)\right)^2=8^2

comparing with the circle equation

\left(x-a\right)^2+\left(y-b\right)^2=r^2

Therefore, the center of the circle is:

  • \left(a,\:b\right)=\left(14,\:-21\right)

Thus, option (2) is true.

Help me with #4 pleasedeeee
Romashka [77]

Answer:

\dfrac{dy}{dx}=-\dfrac{2x-y-1}{2y-x-1}

Step-by-step explanation:

Differentiating, you get ...

... x·dy +y·dx +dx +dy = 2x·dx +2y·dy

Collecting terms gives ...

... dy(x +1 -2y) = dx(2x -y -1)

... dy/dx = -(2x -y -1)/(2y -x -1)
