cadens savings account had $70 in its first year. each year since the , his account accumulated interest amounting to 10% of the valance in the previous year.
let f(n) be cadens account balance at the nth year of the saving
f is a sequence what kind of sequence is it
The supplied question's response based on the savings account is A geometric sequence is the sequence f.
What is Geometric sequence?A geometric sequence is a set of numbers where each term is obtained by multiplying the one before it by a predetermined quantity known as the common ratio. The following is the generic formula for a geometric sequence:
[tex]a, ar, ar^2,ar^3,ar^4,...[/tex]
There are two types of geometric sequences: finite and endless. While an infinite geometric sequence has no end, a finite geometric sequence has a set number of terms.
Because each term is created by multiplying the term that came before by a constant ratio of 1.1, the sequence f is a geometric sequence. (which accounts for the interest that has accrued on the preceding balance using the formula 1 + 0.1).
The first term is for $70, and each succeeding term is equal to the first term times 1.1. As a result, the nth term of the series can be
written as: [tex]f(n)=\$ \times 1.1^{n-1}[/tex]
where n is how long it has been since the first year of saving.

$12715= x2 - 5x + 65
Step-by-step explanation:
To solve for x, we need to isolate the variable on one side of the equation. We can start by subtracting 65 from both sides of the equation:
$12715 - 65 = x^2 - 5x
Simplifying:
$12650 = x^2 - 5x
Next, we can move all terms to one side of the equation:
x^2 - 5x - 12650 = 0
Now, we can use the quadratic formula to solve for x:
x = [-(-5) ± sqrt((-5)^2 - 4(1)(-12650))]/(2(1))
Simplifying:
x = [5 ± sqrt(63225)]/2
x = [5 ± 251]/2
So the solutions are:
x = (5 + 251)/2 = 128
x = (5 - 251)/2 = -123
Therefore, x can be either 128 or -123.

The ratio of the width to the length of a flower bed is 10:19. How long is the flower bed if it's width is 6feet
Answer:
The length of the flower bed is 11.4 feet.
Step-by-step explanation:
If the ratio of width to length of the flower bed is 10:19, this means that for every 10 units of width, there are 19 units of length.
Let's call the width of the flower bed "W" and the length "L". We know that W is 6 feet, so we can write:
W:L = 10:19
Substituting the value of W, we get:
6:L = 10:19
To solve for L, we can cross-multiply to get:
10L = 6 x 19
10L = 114
L = 11.4
Therefore, the length of the flower bed is 11.4 feet.

A car was valued at $45,000 in the year 1991. The value depreciated to $12,000 by the year 2000.
A) What was the annual rate of change between 1991 and 2000?
r=-------------Round the rate of decrease to 4 decimal places.
B) What is the correct answer to part A written in percentage form?
r=------------%
C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2003 ?
value = $----------------Round to the nearest 50 dollars.
The total change in value is $45,000 - $12,000 = $33,000. The annual rate of change is 0.0495. Converting the rate of change to a percentage is 4.95%. Assuming the car value continues to drop by the same percentage, the value of the car in 2003 is $10,850.
What is a percentage?A percentage is a way of expressing a number as a fraction of 100. Percentages are typically expressed using the symbol "%".
In the given question,
A) The total change in value is $45,000 - $12,000 = $33,000. The time period is 9 years (2000 - 1991). Therefore, the annual rate of change is:
r = [tex](Change in value / Initial value) ^ (1/Time period)[/tex] - 1
r = [tex]($33,000 / $45,000) ^ (1/9)[/tex] - 1
r = 0.0495
Rounding this to 4 decimal places, the annual rate of change is 0.0495.
B) Converting the rate of change to a percentage:
r = 0.0495 * 100
r = 4.95%
Therefore, the answer to part A in percentage form is 4.95%.
C) Assuming the car value continues to drop by the same percentage, we need to calculate the value of the car in the year 2003. The time period from 2000 to 2003 is 3 years. Therefore, the value of the car in 2003 can be calculated as follows:
Value in 2003 = $12,000 * [tex](1 - r) ^ 3[/tex]
Value in 2003 = $12,000 * [tex](1 - 0.0495) ^ 3[/tex]
Value in 2003 = $10,840.09
Rounding this to the nearest 50 dollars, the value of the car in 2003 is $10,850.

the line L passes through the points (5,-5) (4,3)
The equation of the line L is y = -8x + 35.
What is the slope?
The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).
To find the equation of the line L that passes through the points (5,-5) and (4,3), we need to use the point-slope form of a linear equation:
y - y1 = m(x - x1)
where m is the slope of the line and (x1, y1) is one of the given points.
First, we need to find the slope of the line L:
m = (y2 - y1) / (x2 - x1)
m = (3 - (-5)) / (4 - 5)
m = 8 / (-1)
m = -8
Now we can use either point to write the equation of the line. Let's use (5, -5):
y - (-5) = -8(x - 5)
y + 5 = -8x + 40
y = -8x + 35
Therefore, the equation of the line L is y = -8x + 35.

It must be less than 4
Answer:
It must be greater than 4
Step-by-step explanation:
We know that 36 ÷ 9 = 4.
Therefore, if the denominator is less than 9 and the numerator is greater than 36, the quotient would only increase since the numerator increases while the denominator decreases.

Ella invested $4,800 in an account paying an interest rate of 2 1 8 2 8 1 % compounded quarterly. Santiago invested $4,800 in an account paying an interest rate of 2 3 8 2 8 3 % compounded daily. After 18 years, how much more money would Santiago have in his account than Ella, to the nearest dollar?
Answer:331
Step-by-step explanation:
7360.3097-7029.415≈330.8947
Santiago could have $81 more than Ella after 18 years.
To calculate the amount of money each person can have after 18 years, we are able to use the formulation for compound interest:
[tex]A = P(1 + r/n)^{(nt)[/tex]
Wherein:
A = the final amountP = the principalr = the interest price n = the number of times the interest is compounded in step with yeart = the number of yearsFor Ella's investment:
P = $4,800
r = 2.28125% = 0.0228125
n = 4
t = 18
[tex]A = 4800(1 + 0.0228125/4)^{(4*18)[/tex]
A = $8,481.48
For Santiago's investment:
P = $4,800
r = 2.28333% = 0.0228333
n = 365 (compounded daily)
t = 18
A = 4800(1 + 0.0228333/365)^(365*18)
A = $8,562.02
The distinction of their final amounts is:
$8,562.02 - $8,481.48 = $80.54
Therefore, Santiago could have $81 more than Ella after 18 years.

You should invest $139.07 each month to end up with $17,000 in 8 years, assuming a guaranteed APR of 4.5%.
What is annual interest rate?The annual interest rate (also known as the annual percentage rate or APR) is the amount of interest that is charged on a loan or investment over the course of one year.
According to question:To calculate the monthly deposit needed to reach the target amount of $17,000 in 8 years at a guaranteed APR of 4.5%, we can use the formula for future value of an annuity:
FV = P * ([tex](1 + r/n)^(n*t)[/tex] - 1) / (r/n)
where FV is the future value, P is the monthly payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.
In this case, we want to find the monthly payment (P), and we know that:
FV = $17,000
r = 4.5% = 0.045 (decimal)
n = 12 (since we are making monthly deposits)
t = 8
When these values are added to the formula, we obtain:
$17,000 = P * ([tex](1 + 0.045/12)^(12*8)[/tex] - 1) / (0.045/12)
Simplifying and solving for P, we get:
P = $139.07
Therefore, you should invest $139.07 each month to end up with $17,000 in 8 years, assuming a guaranteed APR of 4.5%.

Estimate the cost of painting a concrete patio if it is a 12 foot by 14 foot rectangle, and a quart of paint that covers 53 square feet costs $10.99
Answer:
$43.96
Step-by-step explanation:
We first need to find the area of the patio which is 12-foot by 14-foot
12 ft * 14 ft = 168 sq ft
next, we need to know how many quarts are needed to cover the entire area of the patio, and we know a quart cover 53 square feet, so we divide the total area of the patio by 53:
168 sq ft ÷ 53 sq ft/quart ≈ 3.17 quarts
We'll need to buy 4 quarts of paint to cover the entire patio.
The cost of 1 quart of paint is $10.99, so the total cost of 4 quarts will be:
4 quarts x $10.99/quart = $43.96
Therefore, the estimated cost of painting the concrete patio will be around $43.96.
A grassland ecosystem experiences an especially rainy year. During the same
year, the rabbit population in the grassland increases sharply. What is the
most likely reason for this increase?
OA. The ecosystem's carrying capacity is lower, so fewer rabbits have
immigrated and more have died.
B. The ecosystem's carrying capacity is higher, so fewer rabbits have
been born and more have emigrated.
OC. The ecosystem's carrying capacity is lower, so more rabbits have
emigrated and fewer have been born.
D. The ecosystem's carrying capacity is higher, so more rabbits have
been born and fewer have died.
Answer: D. The ecosystem's carrying capacity is higher, so more rabbits have been born and fewer have died.
Explanation: Carrying capacity refers to the maximum number of individuals that an ecosystem can support without causing significant harm to the environment. In this case, the grassland ecosystem experienced an especially rainy year, which likely led to favorable conditions for both the rabbits and their food sources.
With more rainfall, there would be an abundance of vegetation in the grassland ecosystem. This increase in food availability would provide ample resources for the rabbits to thrive and reproduce. As a result, more rabbits would be born during this year.
Additionally, the favorable conditions provided by the rainy year may have also reduced the mortality rate of the rabbits. With plentiful food and water, the rabbits would be less likely to face resource scarcity and increased competition, leading to fewer deaths.

What is line plot?A line plot is a graphical representation of data that involves placing X's or other symbols above a number line to show the frequency of each value in a data set.
Each X represents one occurrence of the data value on the number line. Line plots are useful for quickly visualizing the distribution of a data set, especially when there are only a few unique values in the data set.
Based on the line plot, we can see that there are 2 dog toys that weigh 1/8 of a pound and 3 dog toys that weigh 3/8 of a pound.
To find the total weight of the dog toys that weigh 1/8 of a pound or 3/8 of a pound, we need to add the weights of these toys.
The total weight of the dog toys that weigh 1/8 of a pound is 2/8 of a pound, which simplifies to 1/4 of a pound.
The total weight of the dog toys that weigh 3/8 of a pound is 3 x 3/8 = 9/8 of a pound.
Adding these weights together, we get:
1/4 + 9/8 = 11/8 of a pound
This simplifies to 1 3/8 pounds.
