Amplitude:

we can see that

maximum value is 3

minimum value is -1

so,

A=\frac{max-min}{2}

A=\frac{3+1}{2}

A=2

Period:

It is time completed after which value repeats itself

so, we get

T=\pi -0

T=\pi

12a)
5x + 45 + 3x - 25 = 180
8x + 20 = 180
8x = 160
  x = 20

12b)
2x - 5 = 2(20) - 5 = 40 - 5 = 35
3x - 25 = 3(20) - 25 = 60 - 25 = 35

y = 180 - (35+35)
y = 180 - 70
y = 110

Answer and shown work for 5x + y = 10 -x - y = -2
konstantin123 [22]
Solve first equation for y: 
5x+y=10
y=10-5x. Plug this equation into second equation

-x-(10-5x)=-2
-x-10+5x=-2
4x=8
x=2 (plug x into first equation)

5(2)+y=10
y=0

when Best Buy sells a Samsung 32" flat screen television for $219.99, does the 32" represent the length, width, or diagonal of t
Varvara68 [4.7K]

Answer:

Diagonal

Step-by-step explanation:

The measure of a television is always indicated by providing the length of the diagonal, in inches.

In fact, the actual length and height of a 32" tv are:

- Length:

L = 27.9 inches

- Height:

h = 15.7 inches

For an object with a rectangular shape, such as the TV, the diagonal of the object can be found by using Pythagorean's theorem:

d=\sqrt{L^2+h^2}

where

L is the length of the rectangle

h is the height of the rectangle

Substituting the values above, we find:

d=\sqrt{(27.9)^2+(15.7)^2}=32.0 in.

Which corresponds to the diagonal of the TV.
