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.

Q+|6.4|=9.6 with steps?
Bad White [126]

Answer:

Q = 3.2

Step-by-step explanation:

So basically you would first re-order the equation. 6.4 + Q = 9.6

Then after that you will move all the terms containing Q to the left and the rest of them on the right.  After that you will -6.4 to both sides of the equation. Which will look like this.

6.4 + (-6.4) + Q = 9.6 + (-6.4)

Then you will combine the like terms.

6.4 + (-6.4) = 0.0

0.0 + Q = 9.6 + (-6.4)

<u>Q = 3.2</u>

A. Are the expressions 3(m - 2) + 2(m - 2) and 50m - 2) equivalent expressions?
miss Akunina [59]

Answer:

Step-by-step explanation:

3(m-2)+2(m-2)

3m-6+2m-4

3m+2m-6-4

5m-6-4

5m-10

The expressions 3(m-2)+2(m-2) and 50m-2 are not equivalent expressions.

After simplifying the first expression 3(m-2)+2(m-2) in part (a), we got 5m-10, which is different from the second expression, 50m-2.
