Answer:
A, it starts at 3 since it is non proportional as well as being a postive graph.
Step-by-step explanation:
I assume you're supposed to establish the identity,
cos(A) cos(2A) cos(4A) = 1/8 sin(8A) / sin(A)
Recall the double angle identity for sine:
sin(2<em>x</em>) = 2 sin(<em>x</em>) cos(<em>x</em>)
Then you have
sin(8A) = 2 sin(4A) cos(4A)
sin(8A) = 4 sin(2A) cos(2A) cos(4A)
sin(8A) = 8 sin(A) cos(A) cos(2A) cos(4A)
==> sin(8A)/(8 sin(A)) = cos(A) cos(2A) cos(4A)
as required.
In order to find a percentage, you divide the sample by the total amount.
For example: Tess has 3 cookies out of the total amount of 9. 3/9 = 33.3%
X^4 / x = x^3 so the answer cant be A or B
Must be C
Answer:
$38250
Step-by-step explanation:
Given data
P= $340,000
t= 30-year,
r1= 6.475%
r2= 6.85%
For r1
A= P(1+rt)
A= 340,000(1+0.06475*30)
A= 340,000(1+1.9425)
A= 340,000*2.9425
A= $1000450
For r2
A= P(1+rt)
A= 340,000(1+0.0685*30)
A= 340,000(1+2.055)
A= 340,000*3.055
A= $1038700
The difference is '
= 1038700-1000450
=$38250
