1 answer:

7 0

Let's start with the basic sine function, f(t) = sin(t). This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of 2π because the sine wave repeats every 2π units

The width of a rectangle measures (7d + 8f) centimeters, and its

Andre45 [30]

The expression which represents the perimeter, in centimeters, of the rectangle is; (18d +10f) centimetres.

<h3>Perimeter of a rectangle</h3>

Since the perimeter of a rectangle is given by the formula;

Perimeter, P = 2l + 2w.

In essence, Perimeter, P = 2(2d – 3f) + 2(7d + 8f)

P = 4d -6f + 14d +16f

P = 18d +10f.

Ultimately, the perimeter of the rectangle is; (18d +10f) centimetres.
