True or false: sec^-1(0.5) is undefined. explain your answer
ICE Princess25 [194]

Here we get the statement:

"sec^-1(0.5) is undefined"

And we want to see if this is true or false, so let's use the properties that we know to find that this is false.

Remember that the sec function is defined as:

sec(x) = \frac{1}{cos(x)}

Then we will have:

sec^{-1}(x) = (\frac{1}{cos(x)})^{-1} =  cos(x)

Then is really trivial to see that:

sec^{-1}(0.5) =  cos(0.5) = 0.878

Then we can conclude that the function is not undefined at 0.5, so the statement is false.

Below you can see the graph of the given function, and you will see that it is never undefined.

xenn [34]

Answer:

200 in3

Step-by-step explanation:

To find the volume of a rectangular prism you multiply each dimension to each other. 8*2 is 16, and 16*12.5 is 200. This means the volume is 200 in3.

Hope this helps :)
