It means to solve, or simplify the expression.

Let's give two examples.

1) 5 + 2²
5 + 4
9 <- We are trying to simplify/solve the expression to as far as we can.
9 cannot be simplified, so the expression has been evaluated.

2) 4x - 5x + 9y
-x + 9y <- Can not be simplified any further so the expression has been evaluated via. combining like terms.

For a certain horse race comma the odds in favor of a certain horse finishing in second placehorse race, the odds in favor of a

NikAS [45]

Answer:

0.33

Step-by-step explanation:

Let A denote an event. The odds of the horse finishing second is 33 to 67.

From the information, the total outcomes of event A is:

$Total \ Outcomes, A=Favorable +Unfavorable\\\\=33+67\\\\=100$

Hence, there are 100 total outcomes. The probability of the horse finishing second is calculated as:

$p=\frac{n(A_f)}{n(A_u)}\\\\\\=p=\frac{33}{100}\\\\=0.33$

Hence, the probability of finishing second is 0.33

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.
