Answer:
$34.8
Step-by-step explanation:
Given data
Cost of apartment= $870 per month
increase= 20%
Discount= 8%
Let us find the amount of increase
=20/100*870
=0.2*870
=$174
New cost = 870+174
=$1044
New cost of apartment for 18 month
=1044*18
=$18792
He gave them 8% discount
=8/100*18792
=0.8*18792
=$15033.6
Hence the monthly fee will be
=15033.6/18
=$835.2
Therefore the difference in price is
=870-835.2
=$34.8
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:
The answer is d
Step-by-step explanation:
Because all angles in parallelogram are the same
Answer:
π\6
Step-by-step explanation:
The reference angle is the smallest angle measured from the terminal side of the angle (where the angle ends) to the x axis. The reference angle is an acute angle (i.e less than 90° or π/2)
For O = 11π/6 = 1.833π
1.833π is in the fourth quadrant between 3π/2 radians and 2π radians. Since it is in the fourth quadrant, the reference angle is given as:
reference angle = 2π - 11π/6 = π\6
