For starters,
Consider the 
th partial sum, denoted by 
:
Multiply both sides by 
:
Subtract from this:
Solve for :
Now as 
, the exponential term will converge to 0, since 
if 
. This leaves us with
Answer: 1st one is no solution
and then i cant see the question for the 2nd one
Step-by-step explanation:
Answer:
40% price reduction
Step-by-step explanation:
The tickets were reduced by 40% because 20 is 2/5 or 40% of 50 and that was the amount of the price reduction.
x = longer section
y = shorter section
x + y = 109
x = 2y + 10
so we sub in eq 2 into eq 1
2y + 10 + y = 109
3y + 10 = 109
3y = 109 - 10
3y = 99
y = 99/3
y = 33 <=== shorter section is 33 cm
x = 2y + 10
x = 2(33) + 10
x = 66 + 10
x = 76 <=== longer section is 76 cm

Hello!</h2>
The answer is: 
<h2>
Why?</h2>
Quadratic function describes the graph of a parabola and they are formed by a quadratic term (
) a linear term (
) and a constant number (c). Quadratic terms have an exponent of 2 and linear terms have an exponent of 1.
For this situation, we have only the quadratic term () which is enough to know that there is a quadratic function.
Have a nice day!
