Answer:
inequality form: x<-5
Step-by-step explanation:
Answer:
13 in³
Step-by-step explanation:
This is a skewed pyramid, but that doesn't change the way you find the volume of the figure.
The formula for the volume of a pyramid is 1/3(b)(h)
Multiply 6 by 6.5 to get 39, then divide it by 3 to get 13 in³
Answer:
See proof and explanation below.
Step-by-step explanation:
First we can proof this analitically first using the following property:

If we apply this into our formula we got:

And if we simplify we got:

And that complete the proof.
If we analyze the graphs sin(x) and cos (x) we see that we have a gap between two graphs of
as we can see on the figure attached.
When we do the transformation
we are moving to the left
units and then would be exactly the cos function.
