Answer:

a) Definition of sequence of real numbers: A sequence of real number is the function from set of natural number to the set of real numbers. i.e.

f: <em>N</em> → <em>R</em>

Example: S_{n}=\frac{1}{n}

S_{n}=\frac{n}{n+1}

b) Definition of convergent sequence: A sequence is said to be convergent if for very large value of n, function will give the finite value.

Example: S_{n}=\frac{1}{n}

S_{n}=\frac{n}{n+1}

c) Definition of Cauchy sequence: A sequence is said to be Cauchy Sequence if terms of sequence get arbitrary close to one another.

Since the "size in square feet" is on the X-axis it is represented by the X in the equation. And Y is expected property tax

It is giving you a X-value of 3100. So you just have to plug 3100 into the X spot and solve for Y

y=.392(3100)+638.118
y=1853.318

So the third answer.

A public beach in Florida charges non residents $8 per day for a fishing license and $2.50 per day for live bait. Florida reside
melamori03 [73]

For a non-resident:

C_{nr}=8d+2.5d=10.5d

For a resident:

C_{r}=114+1d

We want to know the number of days d such that the two costs are equal ie \{d|C_{nr}(d)=C_{r}(d)\}

To do this set the two costs equal to each other:

C_{nr}=C_{r}

10.5d=114+1d

And solve for d:

10.5d-1d=114+1d-1d

9.5d=114

d=\frac{114}{9.5}

d=12

The costs will be equal when a resident and a non-resident each use the beach for 12 days.
