Hello!

If you see the word per, you divide. So the price (4)per(/) hotdog (8). This we divide 4/8. This gives us 1/2, or $0.50.

I hope this helps!

Complete the function table. Than write a rule for the function. Show all your work.
REY [17]
Only two points are given. An infinite number of functions can be written that will have graphs going through those two points. We have to assume the only one you're interested in is the linear function.

You can use the 2-point form of the equation for a line to find the function, then use that to fill in the table.
y=\left(\dfrac{y_{2}-y_{1}}{x_{2}-x{1}}\right)(x-x_{1})+y_{1}\\\\y=\left(\dfrac{-1-(-4)}{1-(-2)}\right)(x-(-2))-4\\\\y=\dfrac{3}{3}(x+2)-4\\\\y=x-2

Using this rule Output = Input -2, we can fill in the function table.
\left\, \begin{array}{cc}-3 & -5\\-2 & -4\\-1 & -3\\0 & -2\\1 & -1 \end{array} \right\,

A spotlight on the ground shines on a wall 12 m away. If a man 2 m tall walks from the spotlight toward the building at a speed
Stells [14]
Draw a right angled triangle ABC, where <B = 90 degrees 

<span>BC is the base, and BC = 12 m and C represents spot light on the ground and B is foot of the wall </span>

<span>Draw a perpendicular DE from a point D on hypotenuse, AC to a point E on BC </span>

<span>DE represents walking man and DE = 2 m </span>

<span>Now AB represents height of shadow, let AB = y </span>

<span>let EC = x </span>

<span>from similar triangles, ABC and DEC </span>

<span>AB/DE = BC/EC </span>

<span>y/2 = 12/x </span>

<span>y = 24/x </span>

<span>differentiating with respect to t </span>

<span>dy/dt = - (24/x^2) dx/dt </span>

<span>substitute x = (12 - 4) = 8 and dx/dt = 1.9 m/s </span>

<span>dy/dt = - (24 / 64)(1.9) </span>

<span>= -0.7125 </span>

<span>length of shadow is decreasing at the rate of 0.7125 m /s</span>
