Fiesta28 [93]3 years ago
3 0

Answer:

Step-by-step explanation:

when x=0

y=2 sin 0=2×0=0

when x=π/2

y=2×sin (π/2)=2×1=2

when x=π

y=2 sin π=2×0=0

when x=3π/2

y=2 sin (3π/2)=2×-1=-2

when x=2π

y=2 sin (2π)=2×1=2

if ~0\leq x\leq 2\pi \\initial ~point~is ~(0,2)\\end~point~is ~(2\pi ,0)

Look at this parallelogram. Find the value of c.<br> c<br> 17 m<br> Perimeter=66 meters
sergiy2304 [10]

The value of c is 16.

<u>Step-by-step explanation:</u>

The perimeter of the parallelogram is given by,

Perimeter = 2( base + height )

The one of the dimension is given as 17 m.

Let us assume it has base of the parallelogram.

Therefore,

  • The base of the parallelogram = 17 m.
  • The perimeter of the parallelogram = 66 m.

Let, c be the height of the parallelogram.

<u>To find the value of c :</u>

Substitute the given data in the Perimeter of the parallelogram formula,

Put, height = c, base = 17 and perimeter = 66

⇒ Perimeter = 2 ( base + c )

⇒ 66 = 2 (17 + c)

Multiply 2 with each term inside the bracket,

⇒ 66 = 34 + 2c

⇒ 66 - 34 = 2c

⇒ 32 = 2c

Divide by 2 on both sides,

⇒ c = 32 ÷ 2

⇒ c = 16

Therefore, the value of c is 16.

<h3>Answer:   x = 9</h3>

=========================================

The diagram shows:

  • base = 13
  • height = x

Recall that the area of a parallelogram is equal to the base times height

area = base*height

We're told that the area is 117 square units, so that means 13x = 117.

Divide both sides by 13 to isolate x

13x = 117

13x/13 = 117/13

x = 9

The height of the parallelogram is 9

Note how:

area = base*height = 13*x = 13*9 = 117

which helps confirm we have the correct height value for x.
