Find a function of the form

Mathematics
1 answer:
atroni [7]3 years ago
4 0

Answer:

Step-by-step explanation:

The amplitude is 6, so A=6.

Also, the midline is y=-3, so C=-3.

The period is 10, so 2pi/k = 10 -> k=5.

Now we need to determine if this is a sine graph or a cosine graph. As the y-intercept is not the value of C, we can determine that this is a cosine graph, and thus y=6cos(5x)-3.

What is an estimation strategy<br> This is for 6th grade math please help
Lunna [17]

Answer:

Estimation is a mental process of coming up with an answer that is relatively  close, to allow decisions to be made. The types of estimation are quantity, computation and measurement.

An estimation strategy is simply coming up with a good estimate based on evidence and already known facts. Coming to a conclusion as close to the real answer as you can. It can also be called an educated guess.

Solve the following system of equations using the elimination method. x – y = 11 2x + y = 19 Question 5 options: A) (–3,9) B) (1
taurus [48]

Answer:

x=10, y=-1

(10,-1)

Step-by-step explanation:

x-y=11

2x+y=19

Add these two equations together to eliminate y

x-y=11

2x+y=19

--------------

3x = 30

Divide each side by 3

3x/3 = 30/3

x = 10

Now we need to find y

2x+y = 19

2(10) +y = 19

20+y =19

Subtract 20 from each side

20-20 +y = 19-20

<h2>y= -1 </h2>

Is the sum of 4.2 and the square root of 2 rational or irrational
andrew11 [14]

The <em>correct answer</em> is:


Irrational.


Explanation:


We are adding a rational number, 4.2, and an irrational number, √2.


Adding an irrational number to anything makes the sum irrational.


The only way to get a rational number from an irrational number is to multiply or divide. There is no way to rationalize an irrational number by adding or subtracting.
