Step-by-step explanation:
We know that tan=sin/cos, so tan(x+π/2)=
Then, we know that sin(u+v)=sin(u)cos(v)+cos(u)sin(v),
so our equation is then
Then, cos(u+v)=cos(u)cos(v)-sin(u)sin(v), so our expression is then
Answer:
Step-by-step explanation:
I believe the answer would be 1/4 of the sub. Because they asked about the whole sub. And it says he ate 1/4 of the amount of that half of the sub for snack. So out of the whole sandwich it would be 1/4!
If it’s not the answer your looking for you can take it off...
But...

Answer:
22/5
Step-by-step explanation:
The sides increase but in the same ratio,
Hence opposite/adjacent for image and pre image is the same ratio.
Therefore, tanX is 22/5
Answer:
d
Step-by-step explanation:
Well, all you would do is multiply them all together. When multiplying decimals all you have to do to it is move it two places to the left and multiply.
So you would get $630
