The first option is better because it more accurate. The second option is a terminal number, meaning it goes on and on forever, which will be very difficult to use.

Select the number line that shows the decimal for the following fraction.<br><br> sixth tenths
Komok [63]

Answer:

C

Step-by-step explanation:

to figure this out, lets understand how decimals work

a decimal number in the tens place before the decimal

  ↓ here

0.00

that number will be the same number as the numerator or top number of a fraction in tenths

↓ here

0/10

so say it was 4/10 we needed to find, we would look on the number line for 0.40 like in answer choice B (NOT THE CORRECT ANSWER FOR THIS PROBLEM)

hope this helps you out on your work :)

Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?
vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

f(x)=9-4x^2

If f(-x)=f(x), then f(x) is an even function.

If f(-x)=-f(x), then f(x) is an odd function.

Now, substitute x=-x in the given function.

f(-x)=9-4(-x)^2

f(-x)=9-4(x)^2

f(-x)=f(x)

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether 9-4(-x)^2 is equivalent to -(9-4(x)^2).

Therefore, the correct option is C.
