Answer:
Step-by-step explanation:
The nth term of a geometric sequence is given by the following equation.
In which r is the common ratio.
This can be expanded for the nth term in the following way:
In which 
is the first term.
This means that for example:
So
Then
Answer: 105 degrees
Step-by-step explanation:
105 + 75 = 180 degree angle.
183/3: 61mph
The answer would be 61mph.
Answer:
1. a + b + c = 180
2. b + d = 180
3. d = a + c
Step-by-step explanation:
1. a + b + c = 180:
Angles in a triangle add up to 180
2. b + d = 180:
Angles in a straight line equal 180 because they are supplementary angles
3. d = a + c:
ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d
F(x)=x^3-9x
and
g(x)=x^2-2x-3
so you just need to divide f(x) by g(x)
Therefore:
f(x)/g(x) = (x^3-9x) / (x^2-2x-3)
and of course you need to factor these two function to see if some factor would cancel another
x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
