Answer:
Changing value of "a" changes the amplitude of the sine graph.
Step-by-step explanation:
Question says to find about how does the a value affect your sine graph.
General equation of sine function can be given as:
![y=a\cdot\sin\left(b\left(x-h\right)\right)+k](https://tex.z-dn.net/?f=y%3Da%5Ccdot%5Csin%5Cleft%28b%5Cleft%28x-h%5Cright%29%5Cright%29%2Bk)
There value of "a" gives amplitude.
So changing value of "a" changes the amplitude of the sine graph.
Answer:
920*1.12^t
Step-by-step explanation:
Every year, we see that it goes up 12%.
12% in decimal form is 0.12.
Let's say we have "x" amount of cars one year. The next year, the number of cars will increase by 12%. 0.12x is added on after one year.
So in total, at the beginning of a new year, the number of cars is 0.12x+x = 1.12x.
In this case, we have 920 cars. So if every year the number of cars is multiplied by 1.12, then in "t" years we will have 920*(1.12)^t. We multiply by 920 because that's the current number of cars, and we add the ^t because we multiply by 1.12 every year.
You are very welcome!

Answer:
Option 1 is correct.
Step-by-step explanation:
Given two linear equations to us are ,
![\qquad 3x + 7y = 10 \\\\ \qquad x + y = 2](https://tex.z-dn.net/?f=%5Cqquad%203x%20%2B%207y%20%3D%2010%20%5C%5C%5C%5C%20%5Cqquad%20x%20%2B%20y%20%3D%202%20)
And we have to find which system of linear equations have same answer .
On considering option (1) which is ,
![\qquad 3x + 7y = 10 \\\\ \qquad 2x + 2y = 4](https://tex.z-dn.net/?f=%5Cqquad%203x%20%2B%207y%20%3D%2010%20%5C%5C%5C%5C%20%5Cqquad%202x%20%2B%202y%20%3D%204%20)
On taking the second equation in this ,
This is same as the second one given in the Question . And the first one is already same .
<u>Hence</u><u> </u><u>option</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>is</u><u> </u><u>corre</u><u>ct</u><u> </u><u>.</u><u> </u>
Answer:
![f^{-1}(x)=y/3-1/9](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3Dy%2F3-1%2F9)
Step-by-step explanation:
![f(x)=3x-2/6](https://tex.z-dn.net/?f=f%28x%29%3D3x-2%2F6)
![f^{-1}(x)=x/3-1/9](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3Dx%2F3-1%2F9)
if ![f(x)=(3x-2)/6](https://tex.z-dn.net/?f=f%28x%29%3D%283x-2%29%2F6)
answer:![f^{-1}(x)=(6x+2)/3](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%286x%2B2%29%2F3)
Answer: no because 1/3 is a repeating decimal and 1/4 is a whole number
