Answer:

<em>201.06 sq. ft.</em>

Step-by-step explanation:

Area of a circle is found by using the equation:

$A = \pi r^{2}$

Radius = 1/2 (diameter) = 1/2 (16) = 8

So plug in:

$A = \pi (8)^{2}$

A = 64 $\pi$

A = 201.06193

Rounded A= 201. 06

How do you solve for y in the equation: <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%3Dy-6" id="TexFormula1" title

kozerog [31]

No it isn't.

Explanation:

x/y * y = (y-6) * y

x = y^2 - 6y

A function gives just one y for every x

In this case there will always be 2 y's for every x

Example:

y can be

y = 6

or

y =−6

(0,-6) & (0,6)

Amy's yearly salary is given by the equation y = 25,000 + 700x, where x is the number of years since 2007 and y is her salary in

marissa [1.9K]

Answer:

Amy's yearly salary in 2011 was $27,800

Step-by-step explanation:

we have

$y=25,000+700x$

where

x ---> is the number of years since 2007

y ---> Amy's yearly salary in dollars

To find out what was her salary in 2011, first determine the value of x

$x=2011-2007=4\ years$

substitute the value of x in the equation above

$y=25,000+700(4)$

$y=\$27,800$

therefore

Amy's yearly salary in 2011 was $27,800
