Answer:

10 inches by 7 inches

Step-by-step explanation:

Let L and W represent the length and width of the rectangle, in inches.  Then L = W + 3.

The perimeter is P = 2L + 2W, or P = 2(W+3) + 2W = 34 inches.

Solving for W:  2W + 6 + 2W = 34 inches, or

                         4W + 6 = 34 inches, or

                          4W = 28 inches, or W = 7 inches.

Given that L = W + 3, L = (7 inches) + 3 inches = 10 inches.

The length of the rectangle is 10 inches, and its width is 7 inches.

Determine whether the function shown in the graph is even or odd.
erica [24]

Answer:

Option A) The function is even because it is symmetric with respect to the y-axis.

Step-by-step explanation:

We are given a graph of the function.

We can see that the given function is symmetric around the y axis as the y axis acts as a mirror.

Symmetry around y-axis

  • The y-axis acts as the line of symmetry for the given graph.
  • A graph is said to be symmetric about the  y axis if (a,b) is on the graph, then we can find the point (-a,b) on the graph as well.

Even Function:

  • A function is said to be even if

f(x) = f(-x)

  • A function f is even if the graph of f is symmetric with respect to the y-axis

Odd function:

  • A function is said to be odd if

-f(x) = f(-x)

  • A function f is even if the graph of f is symmetric with respect to the x-axis.

Thus, we can write that the given function is an even function as the the graph is symmetric to the y-axis.

Option A) The function is even because it is symmetric with respect to the y-axis.
