5/2 cos x/2 what is the amplitude and period?

Mathematics

nikklg [1K]3 years ago
3 0

The amplitude is the highest the function ever gets.  That happens when the
cosine is ' 1 '.  At that point, the value of the function is<em>  5/2 </em>.

The period is the first time after zero that the angle in the cosine is  2π .

                                            x/2 = 2π

Multiply each side by  2 :    x = 4π

The period is  <em>4π .</em>

You are given a rectangular sheet of cardboard that measures 11 in. by 8.5 in. (see the diagram below). A small square of the sa
GaryK [48]

Answer:

Terrence's

Step-by-step explanation:

The length of the square that will be cut out is the height of the box.

1. a

Anya's method: 8.5 -1.5 =7, 11- 1.5 =9.5, the height is 1.5, so the volume is height x length x width which is 1.5 x 9.5 x 7 =99.75 squared inches.

Terrence's method: 8.5-3 = 5.5, 11-3 = 8. Vol= 5.5 x 8 x 3 =132 squared inches. 99.75 < 132 squared inches, Terrence's idea would create larger volume.

1. b

The box's size depends on the length/width/height of the cardboard being cut, which is why different measurements / cutting methods for the same size cardboard can result in different box sizes.

2. The square would be cut from all four corners, therefore the sum of the 2 squares on the cardboard cannot exceed the short side of the cardboard. The shorter side of the cardboard is 8.5 inches, divided by 2 = 4.25 inches, hence the squares cannot  be larger than 4.25 inches. Keep in mind that if you cut exactly 4.25 inches you will have a strip of 2.5 inches width that cannot be turned into a box.

If you want to cut 5 inches squares out, depending on how you draw it, it would either overlap or go outside of the paper because 5+5 is ten, surely on the 11 inches side that would still be perfectly fine but for the 8.5 inches side, there isn't any room for the 10 inches.

Answer:

20

Step-by-step explanation:

Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)

Area of a square = (side)² = (√20)² = 20 units²
