Answer:
2.777777 and -7/3
Step-by-step explanation:
2.7182818459 cannot be written in fraction form therefore it is irrational.
2.777777 is rational because it can be written as the fraction 25/9
The square root of 3 is 1.7320508075688772, this number cannot be written as a fraction so it is irrational.
-7/3 is rational because it is already in fraction form.
The answer is x = 3 or x = -8.
Let's solve your equation step by step.
Step 1 - Factor left side of equation
(x - 3)(x + 8)=0
Step 2 - Set factors equal to 0.
x - 3 = 0 or x + 8 = 0
x = 3 or x = -8
Hey there! :D
36/6= 6
From this scale, we know that x has to be 42/6. Since the bigger triangle has a scale of 6 with the similar smaller triangle.
42/6=7
So, x=7
I hope this helps!

Given:
There are given that the parent functions as a cosine function:
Where,
The amplitude of the function is 9.
The vertical shift is 11 units down.
Explanation:
To find the cosine function, we need to see the standard form of the cosine function:

Where,
a is the amplitude of the function,
Now,
According to the question:
The amplitude of the function is 9, which means:

The vertical shift is 11 units down, which means:

For period:

Final answer:
Hence, the cosine function is shown below;
