  • Answer:

<em>l = 16 feet</em>

<em>w = 3 feet</em>

  • Step-by-step explanation:

<em>A = l×w</em>

<em>l = 10+2w</em>

<em>48 = (10 + 2w)w</em>

<em>48 = 10w + 2w² | : 2</em>

<em>24 = 5w + w²</em>

<em>w² + 5w - 24 = 0</em>

<em>w² + 8w - 3w - 24 = 0</em>

<em>w(w + 8) - 3(w + 8) = 0</em>

<em>(w - 3)(w + 8) = 0</em>

<em>w - 3 = 0 => w = 3 feet</em>

<em>w + 8 = 0 => w = - 8 ∉ N </em>

<em>l = 10 + 2w</em>

<em>l = 10 + 6</em>

<em>l = 16 feet</em>

<em />

<em>A = l×w = 16ft×3ft = 48ft² </em>

Graph the function. Describe its position relative to the graph of the indicated function
sweet [91]

Answer:

C

Step-by-step explanation:

If the parent function is function y=f(x) and a>0, then

  • the graph of the function y=f(x-a) is translated a units to the right graph of the parent function;
  • the graph of the function y=f(x+a) is translated a units to the left graph of the parent function;
  • the graph of the function y=f(x)+a is translated a units up graph of the parent function;
  • the graph of the function y=f(x)-a is translated a units down graph of the parent function.

In your case, the grapgh of the function y=2^x+2 is translated 2 units up the graph of the function y=2^x.
