Answer:

READ THE QUESTION CAREFULLY.

y=4sin(\frac{\pi }{2}(x-1))+2

Step-by-step explanation:


Amplitude: Max is at 6, Min is at -2. Halfway point is 2. Subtract Max and Min with Halfway point.

6-2=4

2-(-2)=4

Thus Amplitude is 4.

The Max is at 6. The Min is at -2. Halfway point is at 2. Draw a horizontal line. That is your D. Since the graph has a horizontal shift 1 unit to the right, that will be your C. Draw a vertical line on 1. Usually Sinusoidal axis are (C,D).

Thus (C,D) = (1,2)

Then you need to find the period. When does one mountain completely form?  The Period is 4. (Confused? Draw a mountain and see how it starts and ends).

Thus 4=\frac{2\pi }{B}⇒B=\frac{2\pi }{4}⇒\frac{\pi }{2}

Then put it all together.

General Form: Asin(B(x-C))+D

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

Answer:

y=4sin(\frac{\pi }{2}(x-1))+2

We are given the graph of sine function.
First, we get the amplitude
A = [6 - (-2)] / 2
A = 4

Next, we determine the period and b
T = 4 - 0 = 4
b = 2π / T
b = π/2

The original sine function was
y = 4 sin πx/2

After the transformation, the equation now is
y = 4 sin [π(x+2)/2] + 2

Pleaseee help meeeee question 1 and 2!!!!!
madam [21]

Answer:

I know #1 is a

Step-by-step explanation:

#1 is a because the bus stops twice reaching zero speed to pick up riders then he stops again but since he has to slow down it's not a instant stop so it gradually decelerates twice but since it has a speed it has a constant line (straight) another easy way to tell us to look at the speed and then look the the graph and see if they match so you can elimnate a answer

olga55 [171]

Answer:

Which of the following is a linear function?

  1. y = x^3 + 1
  2. (5/6)x = y − 4
  3. y = 8x^2
  4. y =(1/5)x

<u>2. (5/6)x = y − 4 and 4. y =(1/5)x</u> are the right answers.

Step-by-step explanation:

Linear function is in the form <u>y=ax+b</u><u>.</u>

-100 = -t/5 - 4<br><br>Find t please! (also explain)​
Damm [24]

Answer:

t = 480

Step-by-step explanation:

When we have equations with variables, we always want to isolate the variable, so lets get rid of 4 first.

Add 4 to both sides :

-96 = -t/5

Multiply both sides by the denominator :

-480 = -t

Divide both sides by negative 1 :

t = 480
