Given tan of theta = -2 and pi/2; find cos(2theta)
The identity of cos (2 theta)=
Given tan of theta = -2 and pi/2.
So, let's plug in tan theta= -2
= (Squaring)
= (simplifying)
So, cos ( 2 theta) = -3/5.
Now we can plug in tan theta = π/2
= (Squaring)
= Simplifying
So, cos ( 2 theta)= -3/5 and (4-pi^2)/(4+pi^2)
I need help!!!!! #1 5 1/2 + 0.6x=16 #2 5/9 divided by x = 3 3/4 Thanks!!!!!!!1

Answer:
a) payment: $1082.84
b) interest: $194,822.40
Step-by-step explanation:
The monthly payment on the mortgage can be found using the given formula with the given values of principal (P=195000), interest rate (r=0.053), and time period (t=30). The value of n is 12, corresponding to the number of months in a year.
<h3>a)</h3>The monthly payment is ...
__
<h3>b) </h3>The interest owed is the difference between the total of monthly payments and the principal of the loan:
interest owed = (360)(1082.84) -195000 = 194,822.40
The interest owed over 30 years is $194,822.40.
