Answer:
7/2
Step-by-step explanation:
Slope= y2-y1/x2-x1
(12-5)/(-1--3)
-> (7)/(2)
7/2
Given data
<span>sin (x+pi/2)=cos x
</span>now using sin law
sin(a+b)=sin(a)cos(b)+cos(a)sin(b)
now using above values
sin(pi/2+x)=sin(pi/2)cos(x)+cos(pi/2)sin(x)
as we know that
sin(pi/2)=1
cos(pi/2)=0
now putting these values
sin(pi/2+x)=1*cosx+0*1
sin(pi/2+x)=cosx
hence proved that
<span>sin (x+pi/2)=cos x</span>
Answer:
The solution is 
Step-by-step explanation:
We need to write everything as a power of 3.
We know that:

So

And

This following property is also important:

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side





This means that:



Answer:
A and C
Step-by-step explanation:
ez math
The equation of this equation is 2x/31=22. First, multiply both sides by 31 to get 2x=682. Then, divide both side by two to get x=341, which is 341 home runs by the Yankees that season
