what is the standard form of the equation of a circle with the center 16,4 and a radius of 2 radical 2
Stella [2.4K]

Answer:

(x - 16)² + (y - 4)² = 8

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (16, 4) and r = 2\sqrt{2}, thus

(x - 16)² + (y - 4)² = (2\sqrt{2} )², that is

(x - 16)² + (y - 4)² = 8

The Jeffer's company has a debt ratio (total debt to total assets) of 0.365. If their total debt is $500,000, what are their tot
ch4aika [34]

Given:

Total debt ratio (total debt to total assets) = 0.365

Total debt = $500,000

To find:

The total assets.

Solution:

We know that,

\text{Total debt ratio}=\dfrac{\text{Total debt}}{\text{Total assets}}

On substituting the given values, we get

0.365=\dfrac{500,000}{\text{Total assets}}

\text{Total assets}=\dfrac{500,000}{0.365}

\text{Total assets}=1369863.0137

Therefore, the value of total assets is $1369863.0137.
