Match each polynomial equation to its end behavior. y = -x5 − x4 − x3 − x2 − x − 1 y = x5 + x4 + x3 + x2 + x + 1 y = -x6 + x5 + x4 + x3 + x2 + x + 1 y = x6 + x5 + x4 + x3 + x2 + x + 1 increases as x approaches positive and negative infinity arrowRight decreases as x approaches positive infinity and increases as x approaches negative infinity arrowRight increases as x approaches positive infinity and decreases as x approaches negative infinity arrowRight decreases as x approaches positive and negative infinity arrowRight

Ohn has paid $5730 in first 20 installments

Step-by-step explanation:

As per the question Ohn payed the first installment =$100

Next month Ohn payed the installment = 1.1×$100

Similarly subsequent installment =1.1×1.1×$100

So we can write first 20 installments as

⇒100+100×1.1+100×1.1²+100×1.1³.........+100×

And we know in geometric series

1+x²+x³+........... = (1-)÷(1-x)

Therefore sum of first 20 installments will be

⇒100(1+1.1²+1.1³............ =(1- )÷(1-1.1)

= 100(1-6.73)÷(-.1)

=100×5.73÷.1

= $5730

So Ohn has paid $5730
