Let Yancy's age be = x years

Let her sister's age be = y years

Given is , Yancy is 2 years older than 3 times her younger sister's age, so equation is formed like

x=2+3y  .... (1)

Also given, as her younger sister is 6 years old.

So, y=6

Putting y= 6 in equation (1)

x=2+3(6)

x=2+18

x=20

Hence, Yancy is 20 years old.

Consider the expression: (x + y + 3) × (y + 1).
Vladimir79 [104]

Answer:

1 and 2) After multiplying (x+y+3)(y+1) we have

  • xy+x+y^2+4y+3

Which is an equivalent expression after applying the distributive property.

As we can see we have an one of the variables squared,  so we obtain an Parabolic Cillinder

1. A sine function has the following key features
strojnjashka [21]

Answer:

1) y= 2sin(\frac{1}{2}x) + 2

2) y= 3sin(\frac{\pi}{2}x)-1

3) y= 2sin(2x) -2

Step-by-step explanation:

General form of sin function is

y= Asin(Bx) + C

Where A is Amplitude

B is \frac{2\pi}{\text{Period}}

C is Mid line

1) Given : A sine function has the following key features  

Frequency = \frac{1}{4\pi}

Period is P=\frac{1}{f}=\frac{1}{\frac{1}{4\pi}}=4\pi

Amplitude= 2

Mid line y= 2

Y intercept (0,2)  

This function is NOT a reflection of its parent function of the x-axis

Solution : We put the value in the general form of sin function

A= 2 ,  B=\frac{2\pi}{4\pi}=\frac{1}{2} , C=2

y= Asin(Bx) + C

y= 2sin(\frac{1}{2}x) + 2

2) Given : A sine function has the following key features  

Period = 4

Amplitude = 3

Mid line y = -1

Y intercept (0,-1)

Solution : We put the value in the general form of sin function

A= 3 ,  B=\frac{2\pi}{4}=\frac{\pi}{2} , C=-1

y= Asin(Bx) + C

y= 3sin(\frac{\pi}{2}x)-1

3) Given : A sine function has the following key features  

Period = \pi

Amplitude = 2

Mid line y = -12

Y intercept (0,-2)

Solution : We put the value in the general form of sin function

A= 2 ,  B=\frac{2\pi}{\pi}=2 , C=-2

y= Asin(Bx) + C

y= 2sin(2x) -2
