Expand the left side using the angle sum identity for sine:
sin(<em>x</em> + <em>π</em>/2) = sin(<em>x</em>) cos(<em>π</em>/2) + cos(<em>x</em>) sin(<em>π</em>/2)
cos(<em>π</em>/2) = 0 and sin(<em>π</em>/2) = 1, so the right side reduces to
sin(<em>x</em> + <em>π</em>/2) = cos(<em>x</em>)
as required.
There are 20 nickels in 1 dollar so you would do 20 x 5 which is 100
So there are 100 nickels in 5 dollars :)
Brainliest Answer please.
Answer:
Step-by-step explanation:
The slope intercept form is 
.
The "
" is the slope; which in this case is -3. So 
.
The "
" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.
This is why the answer is .
