Using the identity sin^2(t)+cos^2(t)=1
and
given sin(t)=0.3,
we can find cos(t) by substituting
sin^2(t)+cos^2(t)=1
0.3^2+cos^2(t) = 1
cos^2(t)=1-0.3^2=1-0.09=0.91
cos(t)=sqrt(0.91)= 0.954 ≠ 0.6
So the given proposition is false.
$1,850 is the correct answer. When you divide the interest ($37) by the time in years (0.5) and the interest rate (0.04), you get the correct amount of principal.
That's straight from the source. I feel so bad that your question didn't get answered. It's legit been two years
Answer:
Step-by-step explanation:
a3 = 2
d = -5
=============
a4 = a3 - 5
a4 = 2 - 5
a4 = - 3
===============
a5 = a4 - 5
a5 = -3 - 5
a5 = - 8
Just take a4 as your answer.
