Answer:

wall to bottom of ladder =8 feet

Step-by-step explanation:

using the Pythagorean theorem

ladder length=2W+1

(2W+1)^2=15^2+W^2

4W^2+4W+1=225+W^2

simplify

3W^2+4W-224=0

divide by 3

w^2+1.33W-74.6=0

factor

(W+9.3)(W-8)=0

W=8 feet

Which is true regarding the graphed function f(x)?
Sladkaya [172]
<h2>Explanation:</h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

f(x)=\left(x-4\right)^{2}+5

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

V(4,5)

The graph of this function is shown below. Which is true regarding the graphed function f(x)?

  • It is true that the domain is the set of all real numbers because this is a polynomial function.

  • It is true that the range is the set of all real numbers such that y ≥ 5

  • It is true that this parabola opens upward

  • It is true that it doesn't cut the x-axis
