Eleanor and max used two rectangular wooden boards to make a set for the school play.one board was 6 feet long and the other boa
Oksi-84 [34.3K]

By definition, the area of a rectangle is:

A = w * l

Where,

w: width of the rectangle

l: length of the rectangle

The total area is given by:

A = A1 + A2

Where,

A1: rectangular wooden board 1

A2: rectangular wooden board 2

Substituting we have:

60 \frac{3}{8} = (6) (w) + (5\frac{1}{2}) (w)

Rewriting we have:

\frac{483}{8} = (6) (w) + (\frac{11}{2}) (w)

483 = 48w + 44w\\483 = 92w

w = \frac{483}{92}\\w = 5.25

 w = 5 \frac{1}{4}

Answer:

The width is given by:

w = 5 \frac{1}{4}

A piecewise function g(x) is represented by the graph.
stira [4]

For different function different results are shown below.

<h3>What is Function?</h3>

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.

We have been given a graph of piecewise function. Using that we have to select the function from given choices which is represented by graph.

g(x) = −2x, −2 < x < 0

Answer:

NO. Because g(x) = −2x has negative slope so that means it goes downward also there is no y-intercept in g(x) = −2x but the only graph that has y-intercept in given graph goes upward so that can't be answer.

g(x) = −2, x < −2

Answer:

YES. Because g(x) = −2 is a horizontal line which is only on the left side of x=-2. Graph of this part is present in given graph. So yes it is answer.

g(x) = x − 2, −2 < x < 1

Answer:

NO. Because g(x) = x−2 has y-intercept at y=-2 and slope 1 so that means graph of g(x)= x-2 must be going upward and crossing at y=-2 but there is no such graph. Hence this can't be answer.

g(x) = −2x + 6, x ≥ 1

Answer:

YES. Because g(x) = −2x+6 satisfies the graph which is going downward.

g(x) = x/2+ 1, –2 ≤ x < 1

Answer:

YES. Because g(x) = x/2+ 1 satisfies the graph which is going downward.
