$f(x)=x\sqrt{16-x^2}+c;\ P(3;\ 6)\to x=3\ and\ y=6\\\\subtitute\\\\6=3\sqrt{16-3^2}+c\\\\3\sqrt{16-9}+c=6\\\\3\sqrt7+c=6\ \ \ \ |subtract\ 3\sqrt7\ from\ both\ sides\\\\\boxed{c=6-3\sqrt7}$

A 12-foot basketball hoop has a shadow 9.6 ft long. How long is the shadow of a 6-ft adult standing next to the basketball hoop?

They are proportional, so we can say:

12/9.6 = 6/x

12x = 57.6

x = 4.8ft

Which equation represents a line which is parallel to the line x-3y=15?

LekaFEV [45]

Step-by-step explanation:

Two lines that are parallel have the same slope. If we make $x - 3y = 15$ in to slope-intercept form it'll be like this:

$x - 3y = 15 \\ -3y = 15 - x \\ y = \frac{15 - x}{-3} \\ y = \frac{1}{3}x - 5$

Now we know $y = \frac{1}{3}x - 5\\$ as its slope-intercept form we can see the slope is $\frac{1} {3}\\$ .

$y = \frac{1}{3}x + 4\\$ has the same slope as $y = \frac{1}{3}x - 5\\$ so they are both parallel.

<h3>Answer:</h3>

$y = \frac{1}{3}x + 4\\$
