Write an equation for a circle with center at (5,-2) and diameter of 8 centimeters.

mars1129 [50]

Answer:

$(x-5)^2+(y+2)^2=16$

Step-by-step explanation:

lol brainlessly...

General Circle function: $(x-h)^2+(y-k)^2=r^2$ , where h is the x-coordinate of the center, k is the y-coordinate of the center, and r is the radius.

The radius of the circle is half the diameter so: 8 / 2 = 4

The x-coordinate of the circle is 5

The y-coordinate of the circle is -2

Plug in.

$(x-5)^2+(y-(-2))^2=4^2$

$(x-5)^2+(y+2)^2=16$

A function is shown f(x) = 2/3x +3 what is the value of f (6)?

Katena32 [7]

Answer:

The answer is 28/9

Step-by-step explanation:

Step one

Given information

We are given that the function is

$f(x) = 2/3x +3$

And we are expected to find f(6), that is substitute the value of x with 6

Step two:

$f(6)= 2/3(6)+3\\\\f(6)=2/18+3\\\\f(6)=1/9+3\\\\f(6)=1+27/9\\\\f(6)= 28/9$

What does 12(6-k) equal

gregori [183]

$\text{Hey there!}$

$\rightarrow\text{What does 12(6 - k) equal?}$

$\text{Well, the formula is: a(b + c) = a(b) + a(c) = ab + ac}$

$\bf{12( 6 - k) = 12(6) - 12(k)= \underline{72 -12k}}$

$\boxed{\boxed{\text{\bf{Thus, your answer is: 72 - 12k}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
