The exponential form of given number 121200 is 1.212 ×
And the earth sun distance in kilometers in powers of 10 notation is 1.5 ×
For given question,
We need to express 121,200 in exponential (powers of 10) notation.
To use scientific notation, pick a value between 1 and 10, then multiply it by 10ˣ.
The number between 1 and 10 in 121200 is 1.212 with 5 decimal points.
So, the exponential notation of given number would be,
121,200 = 1.212 ×
Earth's average distance from the Sun is around 93 million miles (150 million kilometers). That's one AU.
So the number between 1 and 10 in 150,000,000 is 1.5, with 8 decimal points.
So, the distance between he Earth and the Sun is:
150,000,000 = 1.5 × 10⁸
Therefore, the exponential form of given number 121200 is 1.212 ×
And the earth sun distance in kilometers in powers of 10 notation is 1.5 ×

Answer:
A) If the domain of y=cos(x) is restricted to [0, π], y=cos^-1(x) is a function.
Step-by-step explanation:
In order for the inverse function to be a function, the original must pass the horizontal line test: a horizontal line must intersect the function in only one place.
As you can see from the attached graph, restricting the cosine function to the domain [0, π] allows it to pass the horizontal line test, so its inverse will be a function.
__
Restricting the domain to [-π/2, π/2] does not limit cos(x) to something that will pass the horizontal line test.
