Answer:
see explanation
Step-by-step explanation:
Using the identity
tan x =
Consider the left side
= ( multiply numerator and denominator by cos²x to clear fractions
= ← ( cos²x + sin²x = 1 ]
= cos²x - sin²x
= right side , thus proven
Which fraction represents the product of -7/8 and -9/11 in simplest form?

For this case we have the following expression:
The difference of both numbers is:
We note that for number 14 we have:
tens place: 1
ones place: 4
Therefore, number 14 can be rewritten as:
Thus, the given expression can be rewritten by replacing values such as:
Then, for associative property we have:
We observe that the difference is also 8.

Rewriting:
A=future amount
P=present amount
r=rate in decimal
t=time in years
n=how many tmes per year it is compounded
they want 110,000=A
present amount=?
rate is 6% or 0.06
time is 12 years
semianually means 2 times per year, so n=2
divide both sides by (1.03)^24 using your graphinc calculator
