Use the initial term and the recursive formula to find an explicit formula for the sequence an. Write your answer in simplest form. an=-2 an = an-1 -13 an=
From the recursive rule
[tex]a_n = a_{n-1}-13[/tex]
it follows that
[tex]a_{n-1}=a_{n-2}-13 \implies a_n = a_{n-2} - 2\times13[/tex]
[tex]a_{n-2}=a_{n-3}-13 \implies a_n = a_{n-3} - 3\times13[/tex]
and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with
[tex]a_n = a_1 + (n-1)\times13[/tex]
so that the explicit rule for the n-th term in the sequence is
[tex]a_n = -2 + 13(n-1) \implies a_n = \boxed{13n-15}[/tex]

Identify the relation that is a function. city name to state name number of apples purchased to the cost of the apples days of the week to the months of the year last name to phone number
Answer:
number of apples purchased to the cost of apples
Step-by-step explanation
The only relation that is a function is number of apples purchased to the cost of the apples.
A relation is considered a function if each input (domain element) is associated with exactly one output (range element). Let's analyze the given relations:
City name to state name: This is not necessarily a function. Multiple cities can be in the same state.
Number of apples purchased to the cost of the apples: This is a function. Each number of apples purchased is associated with a single cost of apples.
Days of the week to the months of the year: This is not a function. Some days of the week might correspond to multiple months.
Last name to phone number: This is not necessarily a function. Different people with the same last name could have different phone numbers.

Step-by-step explanation:
option C is the correct answer.
Direct variation: y = kx .........where k is constant.
10 = k * -5
k = -2
Then check if all are linear and matches.
y = -2 * -4
y = 8 ...matches.
then
y = -2 * -3
y = 6 ........matches
then
y = -2 * -2
y = 4 ........matches
then
y = -2*-1
y = 2 ......matches as well. so direct variation.
What is the domain of the function graphed below?
Answer:
The domain is the set of x values for which the function resides in.
In this graph, it is unclear as to if the function goes on to infinity, but if it does, the answer is quite easily:
(-2, 4] and [7, ∞)
since the function starts on the left at -2 then continues to the right, with a pause, then indefinitely after.

The parent function, f(x) = 5^x, has been vertically compressed by a factor of one-half, shifted to the left three units and down two unlts.
Choose the correct function to represent the transformation.
Answer: Choice C
[tex]\displaystyle g(x) = \left(\frac{1}{2}\right)5^{x+3}-2[/tex]
=====================================================
Explanation:
The 1/2 out front handles the vertical compression by 1/2. For example, if two points are vertically spaced by 10 units, then their new vertical distance is now (1/2)*10 = 5 units.
The x+3 in the exponent means "shift 3 units to the left". Effectively what's going on is that the old input x is now x+3, ie 3 units larger than before. This shifts the xy axis itself 3 units to the right. If we held the curve fixed in place while the xy axis moved like this, then it gives the illusion the curve is moving 3 units to the left.
Then finally the -2 at the very end shifts the curve down 2 units. This is because whatever the y coordinate is, we subtract 2 from it to do this vertical shifting. For example, the point (0,62.5) shifts 2 units down to (0,60.5)

b) the number of people (n) Anita can invite depends on her age (A) and you add (+) 2.
therefore, n= A +2
2.a) n represents the no of phones he sells.
so if he charges $10 for a phone, then
n × 10 will represent the amount of money he makes for the no of phones he sells. you are given that P represents the amount of money he makes from selling a phone which is 10N and also his weekly salary, $ 250. this is the amount of money he receives for the whole week.
Hence, 10n + 250 = P
ans: P= 10n + 250
b) the next week he sells 20 phones. he charges $10 per phone. then he will make $200 from selling the phones. but he will also receive his weekly salary, which is $250. total money he receives equals $450.
a better way to reach the answer is using the above equation:
P = 10n + 250, where n= 20
P= (10*20) + 250
P= $450

A farmer owns a total of 19 ducks and horses.
The ducks and horses have 64 legs altogether.
How many horses are there?
Answer:
6 ducks and 13 horses
Step-by-step explanation:
Let H and D be the numbers of Horses and Ducks, respectively.
We are told that:
H + D = 19
Our biology book confirms that:
1 horse = 4 legs, and
1 duck = 2 legs
[In most cases on Earth]
So we can say that:
4H + 2D = 64 legs
Rewrite
H + D = 19 as: H = 19 - D
and then substitute:
4H +2D = 64 legs
4(19-D) +2D = 64 legs
76 - 4D + 2D = 64 legs
-2D = - 12
D = 6 [We have 6 ducks]
Then:
H + D = 19
H + 6 = 19
H = 13 [There are 13 horses]
=============================
Check:
Do 6 ducks and 13 horses have a total of 64 legs?
6*2 + 4*13 = 64?
12 + 52 = 64?
YES
