Hello!

The equation for a circle is

(x-h)^{2} +(y-k)^{2} =  r^{2}

r is the radius

To find the radius we take the square root of the number in the radius spot

sqrt169 = 13

The answer is 13

Hope this helps!

What are the solutions of 12 – x2 = 0?
Kruka [31]

Answer:

x = ± 2\sqrt{3}

Step-by-step explanation:

Given

12 - x² = 0 ( add x² to both sides )

12 = x² or

x² = 12 ( take the square root of both sides )

x = ±\sqrt{12}

  = ± \sqrt{4(3)} = ± 2\sqrt{3}

Please help!!!! ASAP giving brainiest
mariarad [96]

Answer:

JK=2.25\ units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

so

\frac{JK}{ST}=\frac{KL}{TU}

substitute the given value and solve for JK

\frac{JK}{1.5}=\frac{6}{4}

JK=(1.5)\frac{6}{4}

JK=2.25\ units

Hey factory can produce fifth refrigerators in eight hours how many hours would it take to produce 1250 refrigerators
jarptica [38.1K]

Hey, I'm assuming you mean five refrigerators every eight hours. So . . .

1250 divide by 5. Which gives you 250.

Then take that 250 and multiply it by 8, and you have 2000.

So it would take 2000 hrs for a factory, that can produce 5 refrigerators every eight hours to, produce 1250 refrigerators.

Why is f(x)=0 the only odd and even function?
kupik [55]
F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.

f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.
