Answer:
Surface area = m².
And domain will be x∈ (0,∞)
Step-by-step explanation:
An open rectangular box with volume 4 m³ has a square base.
The length of a side of the base is x
We can say that
=>
Surface area can be found as:
Surface area = m².
And domain will be x∈ (0,∞) we can also say x>0
x is greater than zero as the surface area will always be a positive value and x cannot be negative.
Answer:
B, C, F
Step-by-step explanation:
For the first part, this is the negative angle identity of the sine and cosine function. These identities are:
Then (I believe I am reading this right), B is true. I am unsure because of the repeated value in the middle. The next piece is that sine is odd. By definition, an odd function is one such that:
As we just demonstrated with the identities, sine obeys this and therefore is odd. Cosine, on the other hand, is even because it follows:
Last, the period of sine, or the distance on the x-axis it takes to complete one full wavelength, and the answer is . If you look at a graph of the sine function, you will find that the wave repeats itself at the
mark and it does this with cosine as well.
