OMG !!!!!!! I HAVE THE SAME QUESTION TO ASK
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:
20 Blocks
Step-by-step explanation:
First you would realize that 5 blocks is only 1/4 of the way to school because 1/4 is 25%
Next you should know that you just need to add 5 four times.
Lastly you would multiply 4*5=20
So therefore she lives 20 blocks from her school
Answer:
The slope is 2
Explanation:
The equation is written in y=mx+b
M would always be the slope and b the y intercept
Hope this helps!!
<u>We are given</u>
- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.
When we substitute the radius in the formula, we get;
Take π as 3.14
Simplify the numerator;
Divide the numerator by 3;
