Answer:
c(1) = -15
c(n) = c(n - 1) + 4
Step-by-step explanation:
Given arithmetic sequence is,
-15, -11, -7, -3...........
Common difference between each successive and previous term is,
d = -11 - (-15)
= -11 + 15
= 4
Since recursive formula of the arithmetic sequence is represented by,
a₁ = First term of the sequence
a(n) = a(n - 1) + d
where a(n) is the nth term and a(n-1) is the previous term of the nth term.
Form the given sequence,
c₁ = -15
c(n) = c(n - 1) + 4

1. There are 2 hiking trails in Watkins Park. The Spicebush Trail is 2.7 miles and the Loop Trail is 1.7 miles. If you hiked both trails, how many miles would you walk?
2. On your hike, you brought 1.7 pounds of almond trail mix and 1.4 pounds of cashew trail mix. How much trail mix do you have all together?
3. At the end of the hike you still had 2 pounds of trail mix left. How much trail mix did you at on the hike?
4. Solve these decimal addition and subtraction problems with your base-10 blocks or a number line:
5.3 + 7.4

1. Add 2.7 and 1.7 together to discover the total amount
2.7 + 1.7 = 4.4
You would walk 4.4 miles if you walked both trials.
2. Add the amounts of both trail mixes together
1.7 + 1.4 = 3.1
There were 3.1 pounds of trail mix brought on the hiking trip
3. Subtract answer from 2 by 2 and recieve the answer for this question

Admission to the zoo costs $15 per person.
The graph y = 15x correctly represents the total cost for a group to visit the zoo.
Given;
Admission to the zoo costs per person = $15
Let:
The total number of people visiting the zoo = x
The total cost for a group to visit the zoo = y
So, y ∝ x
y = 15x
Therefore, the graph y = 15x correctly represents the total cost for a group to visit the zoo.

Determine the number of solutions you will have for the system 4y + x = 16 and y = 4 – x.
Equaling both equations, it is found that the correct option that states the number of solutions you will have for the system is:
D: one solutionThe equations are:
[tex]4y + x = 16 \rightarrow x = 16 - 4y[/tex]
[tex]y = 4 - x \rightarrow x = 4 - y[/tex]
Equaling both equations for x, we have that:
[tex]16 - 4y = 4 - y[/tex]
[tex]3y = 12[/tex]
[tex]y = \frac{12}{3}[/tex]
[tex]y = 4[/tex]
[tex]x = 4 - y = 4 - y = 0[/tex]

6/24 divided by 12/16 show work please
The value when 6/24 is divided by 12/16 is equal to 1/3.
To divide the fraction 6/24 by 12/16, we can simplify the problem by multiplying the first fraction by the reciprocal of the second fraction.
Reciprocal of 12/16 is 16/12.
So, the division can be written as:
6/24 ÷ 12/16 = 6/24 × 16/12
6/24 = (6 ÷ 6) / (24 ÷ 6) = 1/4
16/12 = (16 ÷ 4) / (12 ÷ 4) = 4/3
Now, we have:
1/4 × 4/3
To multiply fractions, we multiply the numerators together and the denominators together:
(1 × 4) / (4 × 3)
= 4/12
The fraction 4/12 by dividing both the numerator and denominator by their greatest common divisor, which is 4:
(4 ÷ 4) / (12 ÷ 4)
= 1/3
Therefore, 6/24 divided by 12/16 is equal to 1/3.

The designers of a new website expect the number of visitors to the site to double each month. There were 600 visits to the site the first month. Which function can be used to predict the number of visitors during month m
The exponential function used to predict the number of visitors during month m is [tex]y = 600(2)^m[/tex]
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the factor.
Let y represent the number of visitors during month m.
There were 600 visits to the site the first month and they double each month, hence:
a = 600, b = 2
The exponential function is given by:
[tex]y = 600(2)^m[/tex]

a1 = 3 and r = -5 so:
an = 3/5 * (-5)^n
Plugging in 8 for n (the first choice) we get the given term: -234,375
Answer:
(d) 2 +(-5) +(-12) +... (a) a8Step-by-step explanation:
1.Putting n = 0 and n = 1 into the expression being summed will show you which series is correct.
2 -7n for n=0 is 2 -7·0 = 2
2 -7n for n=1 is 2 -7·1 = -5
The series of the last choice (d) is correct.
__
2.The given sequence is exponential with a first term of 3 and a common ratio if -5. Then the n-th term is ...
an = 3(-5)^(n -1)
We want to find n for an = -234,375.
-234375 = 3(-5)^(n-1)
-78125 = (-5)^(n-1)
For n to be a real number, we must have n even. In that case, the value of n is equivalent to the value that is the solution to ...
78125 = 5^(n -1)
Taking logs of both sides, we get ...
log(78125) = (n -1)·log(5)
log(78125)/log(5) = n -1 . . . . . . . . . . . . divide by log(5)
n = 1 +log(78125)/log(5) = 1 +7 = 8 . . . add 1 and evaluate
-234,375 is the 8th term of the sequence.

First National Bank is offering 4.25% interest on an account. Susan makes an
initial deposit of $20,000. Calculate the interest camed over 20 years if the
bank...
a) Calculates the interest using simple interest (I -- Prt).
b) Calculates the interest using compound interest compounded annually.
c) Calculates the interest using compound interest compounded quarterly.
d) Calculates the interest using compound interest compounded monthly.
The simple interest earned is $17,000.
The interest earned with annual compounding is $25,978.13.
The interest earned with quarterly compounding is $26,583.59.
The interest earned with monthly compounding is $26,722.72.
The formula that can be used to determine simple interest is: principal x time x interest rate
$20,000 x 20 x 0.0425 = $17,000
The formula that can be used to determine the interest earned with compounding is: Future value - amount invested.
The formula that can be used to determine future value is:
FV = P (1 + r/m)^nm
FV = Future value
P = Present value
R = interest rate
m = number of compounding
N = number of years
Annual compounding = $20,000 x (1.0425)^20 = $45,978.13
Interest earned = $45,978.13 - $20,000 = $25,978.13
Quarterly compounding = $20,000 x (1 + 0.0425/4)^80 = $46,583.59
Interest earned = $46,583.59 - $20,000 = $26,583.59
Monthly compounding = $20,000 x (1 + 0.0425 /12) ^240 = $46,722.72
Interest earned = $46,722.72 - $20,000 = $26,722.72
