Answer:

86 yd

Step-by-step explanation:

the area of the shaded region is 2924 yd²

let b the doted side next y :

the area of the total triangle is :

A = (y+b)*68/2 = 2924+ b*68/2

  • \frac{(y+b)*68}{2} = \frac{b*68}{2} + 2924
  • \frac{68*(y+b-b)}{2} = 2924
  • 68*y/2 = 2924
  • 68y = 2*2924
  • y= (2*2924)/68
  • y= 86 yd

consider the following.find formula simplify answer .Find the domain for the formula and round answer to two decimal places if n
Elanso [62]

The sum of functions is given as:

(f+g)(x)=f(x)+g(x)

In this case we have:

(f+g)(x)=5x+\sqrt[]{x-1}

The domain of the functions is any number that makes the squared root a real number, then:

\begin{gathered} x-1\ge0 \\ x\ge1 \end{gathered}

Hence the domain of the functions is:

\lbrack1,\infty)
