Answer:

Amplitude =2 ,

Time period =   \frac{2\pi }{1}.

Phase shift =  π.

Step-by-step explanation:

Given :  f(x) = 2 sin(x + π) − 4.

To find : What are the amplitude, period, phase shift, and midline.

Solution : We have given that f(x) = 2 sin(x + π) − 4.

Standard form of sine function : y=Asin(Bx+C) + D.

Where, A = amplitude , Time period =  \frac{2\pi }{B},  C = phaseshift

Midline , D = vertical shift.

On comparing

amplitude =2 ,

Time period =   \frac{2\pi }{x}.

Phase shift =  π.

Therefore, amplitude =2 ,

Time period =   \frac{2\pi }{1}.

Phase shift =  π.

Given that f(x)=2sin(x+π), the standard form of sine function is y=A=sin(Bx+C), with:
A=amplitude
2π/B=period
C/B=phase-shift
A=2=amplitude
B=1
period=2π/B=2π/1=2π
C=2π/1=2π

What makes a trapezoid an isosceles trapezoid?
swat32
B. It’s bases are congruent

Explanation: A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.

Aisle 2 of a furniture store stocks 4-legged chairs, 4-legged tables, and 3-legged stools. If there are t tables, c chairs, and
aev [14]

Answer:

T=4c+4t+3s

Step-by-step explanation:

Stocks contains:

4-legged chairs

4-legged tables

3-legged stools

So, 1 chair has legs = 4

So, c chairs has legs = 4c

1 table has legs = 4

So, t tables has legs = 4t

1 stool has legs = 3

So, s stools has legs = 3s

Let T denotes the total no. of legs

So, the total number of furniture legs in aisle 2 :

T=4c+4t+3s

Hence T=4c+4t+3s  expression show the total number of furniture legs in aisle 2
