Answer:

B

Step-by-step explanation:

The parent sine function is given by y=sin(x). For this function we have the following data

Period:2\pi

Phase Shift: 0 for Phase Shift is given by y=sen(x-k)=senx Then sin(x-0)=sinx

-k=0

When we transform this function, dilating it, we multiply the function by 1/4 or divide by 4, so we compress it. And Increase the phase shift by adding values to the x, like it was done in

y= 1/4 sin[4(x+pi/6)]

Period: \frac{\pi}{2}

Phase shift: - (\pi/6) For y=1/4 sin[4(x+pi/6)] as the sign of +\frac{\pi}{6} the phase shift is actually -\frac{\pi}{6} units, or \frac{\pi}{6} to the left.

The length of a rectangle is four more than three times the width. If the perimeter of this rectangle is at least 70 square cent
FrozenT [24]

Answer:

Step-by-step explanation:

Let L represent the length of the triangle.

Let W represent the width of the triangle.

The length of a rectangle is four more than three times the width. This means that

L = 3W + 4

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If the perimeter of this rectangle is at least 70 square centimeters, an inequality that can be solved to find the width of the rectangle is

2(L + W) ≥ 70

L + W ≥ 70/2

L + W ≥ 35
