Find the coordinates of the center of the following circle.<br><br> (x - 3)² + (y - 7)² = 49
Zepler [3.9K]

When you write the equation of a circle in the form

(x-x_0)^2+(y-y_0)^2=r^2

Then the center of the circle has coordinates (x_0, y_0) and the radius is r

So, in your case, the center of the circle is (3,7)

HELP ME PLEASEE i need help
sattari [20]

Answer:

x=2

Step-by-step explanation:

Add all the sides to find the perimeter

x+4 + 4x+10(x-1) = 24

Distribute

x+4+4x +10x-10 = 24

Combine like terms

15x -6 = 24

Add 6 to each side

15x-6+6 = 24+6

15x = 30

Divide each side by 15

15x/15 = 30/15

x = 2

Please help me understand this
Elena-2011 [213]
We have the equations of 3 functions and we want to find which one of them will decay the fastest to 4 grams.

This can be done by setting each expression equal to 4 and find which of them gives the smallest value of t.

For Amount A:

4 =8e^{-0.1386t} \\  \\  &#10;\frac{1}{2}=e^{-0.1386t} \\  \\  &#10;ln(\frac{1}{2})=ln(e^{-0.1386t}) \\  \\ &#10;-0.693=-0.1386t \\  \\ &#10;t=3.775

Likewise for Amount B:

4=10e^{-0.2t} \\  \\ &#10; \frac{2}{5}= e^{-0.2t} \\  \\ &#10;ln(\frac{2}{5})=ln(e^{-0.2t})  \\  \\&#10;-0.916=-0.2t \\  \\ &#10;t=4.58 &#10;

Similarly for Amount C:

4=9e^{-0.3t}  \\  \\ &#10;ln( \frac{4}{9})=ln(e^{-0.3t} ) \\  \\ &#10;-0.811=-0.3t \\  \\ &#10;t=2.073

Thus Amount C will take the minimum time to decay to 4 grams.
