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

PLEASEEE ANSWERRRR EASYYYYYY!!!! I WILL MARK BRAINLIEST!!
Tatiana [17]

Answer:

108units^2

Step-by-step explanation:

1) area of a trapezoid formula:

((a+b)/2)h

where a=base 1

b= base  2

h=height(24)

so

(8+1)/2=4.5

4.5*24=108

area is 108 units^2
