.253 move the decimal 2 places to the right then you get 25.3%
Answer:
The distributive property makes it possible
Step-by-step explanation:
Step one:
given the expression a(b + c )
the first step is to open the bracket, that is multiply all the terms in the bracket by a, so multiply b by a and c by a also.
Step two:
Thus, this property is called the distributive property of multiplication
a*b+ca
Answer:
= 40°
Step-by-step explanation:
180-115=65°
65+75=140°
180-140=40°
=40°
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.
