Anne has opened up a systematic savings account into which she deposits $500 per month compounded monthly at a rate of 7.8%. How long will it take her to reach $500,000? Round your answer to the nearest tenth of a year.
Help, please!! I need a step-by-step tutorial. Or just the formula and how is set up. Thank you <33
Answer:
Step-by-step explanation:
The formula for calculating the time it takes to reach a target amount with a constant periodic deposit is given by
Time = ln(Target Amount / (Periodic Deposit x (1 + Interest Rate)^0)) / ln(1 + Interest Rate)
In this case, we have Target Amount = 500,000, Periodic Deposit = 500, and Interest rate = 7.8%. Plugging the values into the formula gives
Time = ln(500,000 / (500 x (1 + 0.078)^0)) / ln(1 + 0.078)
Time = ln(500,000 / 500) / ln(1.078)
Time = ln(1,000) / ln(1.078)
Time = 8.98 years
Rounding to the nearest tenth of a year, the answer is 8.9 years.

Answer:
3π - π√2/2 or 7.2 cm-------------------------
According to the given we can state:
AD = BC = AB = 2AO = 2,EO is the perpendicular bisector of AB,Arc AC and arc BD are of equal length.Find arc AB, it is a semicircle of 1 cm radius:
arc(AB) = 1/2 × 2πr = πr = π cmΔAEO and ΔBEO are both isosceles, hence ∠A and ∠B are both 45°.
Find arcs ABD and BAC:
arc(ABD) + arc(BAC) = 2 × 45/360 × 2πr = 1/2 × πr = π cm∠AEB is a right angle since ∠AEO and ∠BEO are both 45°.
Hence ∠CED is also right angle as vertical angle with ∠AEB.
Find the length of EC and ED.
We know AD = BC = 2 cm and ΔAEO is 45° right triangle.
It gives us:
AE = √2Then:
ED = AD - AE = 2 - √2Find arc ECD:
arc(ECD) = 1/4 × 2πr = 1/2 × π(2 - √2) = π - π√2/2 cmThe perimeter is the sum of all the arc measures:
P = π + π + π - π√2/2 = 3π - π√2/2 or 7.2 cm (rounded)Answer:
[tex]\textsf{Perimeter}=3\pi-\dfrac{\pi}{\sqrt{2}}=7.20333649...\; \sf cm[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $=r \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]
To convert degrees to radians, multiply the angle in degrees by π/180°.
Arc AB
As arc AB has center O, the radius of arc AB is OA = 1 cm.
As AB is a straight line, ∠AOB is 180° = π.
Therefore, the length of arc AB is:
[tex]\implies AB=r \:\theta=1 \cdot \pi = \pi[/tex]
Arc AC
Triangle BOE is a right triangle with base of 1 cm and height of 1 cm.
Therefore, ∠OBE is 45° = π/4
If arc AC has center B, then the radius is AB = 2 cm.
Therefore, the length of arc AC is:
[tex]\implies AC=r \:\theta=2 \cdot \dfrac{\pi}{4} = \dfrac{\pi}{2}[/tex]
Arc BD
Arc BD is the same as arc AC.
[tex]\implies BC= \dfrac{\pi}{2}[/tex]
Arc CD
As triangle BOE is a right triangle with base of 1 cm and height of 1 cm, the length of its hypotenuse BE is:
[tex]\implies BE=\sqrt{1^2+1^2}=\sqrt{2}[/tex]
As arc AC has center B and radius of AB = 2 cm, then BC is also its radius and therefore BC = 2 cm
Therefore:
[tex]\implies CE=BC-BE[/tex]
[tex]\implies CE=2-\sqrt{2}[/tex]
The arc CD has center E so its radius is CE = 2-√2.
As ∠BEO and ∠AEO are both 45° then ∠AEB is 90°.
According to the vertical angle theorem, ∠CED is also 90° = π/2.
Therefore, the length of arc CD is:
[tex]\implies CD=r \:\theta=(2-\sqrt{2}) \cdot \dfrac{\pi}{2} = \dfrac{(2-\sqrt{2})\pi}{2}[/tex]
Perimeter of the egg
The perimeter of the egg is the sum of the found arcs:
[tex]\implies \textsf{Perimeter}=AB+AC+BD+CD[/tex]
[tex]\implies \textsf{Perimeter}=\pi+\dfrac{\pi}{2}+\dfrac{\pi}{2}+\dfrac{(2-\sqrt{2})\pi}{2}[/tex]
[tex]\implies \textsf{Perimeter}=2\pi+\dfrac{(2-\sqrt{2})\pi}{2}[/tex]
[tex]\implies \textsf{Perimeter}=2\pi+\dfrac{2 \pi}{2}-\dfrac{\sqrt{2}\:\pi}{2}[/tex]
[tex]\implies \textsf{Perimeter}=3\pi-\dfrac{\sqrt{2}\:\pi}{2}[/tex]
[tex]\implies \textsf{Perimeter}=3\pi-\dfrac{\pi}{\sqrt{2}}[/tex]

Suppose Kristen is researching failures in the restaurants business
The standard deviation of the number of restaurants that failed within a year is 3.46.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the probability that an independent restaurant will fail in the first year is 48%. Therefore, the probability can be written as,
p = 48% = 0.48
q = 1-p = 1-0.48 = 0.52
Also, Kristen obtains a random sample of 66 independent restaurants that opened in her city more than one year ago and determines if each one had closed within a year. Therefore, the sample size is 53.
n = 53
Now, the standard deviation can be calculated as,
Standard deviation, σ = √(npq)
= √(53 × 0.48 × 0.52)
= √11.9808
= 3.46
Hence, the standard deviation is 3.46.

Answer:
To complete the transactions in your register:
Beginning balance on October 1: $542.89
On October 7, you pay Land Electric $43.90. This is a check transaction and the check number is 400. To record this in your register, you would subtract $43.90 from your current balance, which would bring your new balance to $498.99.
On October 23, you deposit your paycheck. To calculate your paycheck, you would multiply your hourly wage ($7.25) by the number of hours worked (40) by the number of weeks (2). This would give you a gross pay of $1140. Then, you would calculate the deductions: FICA (7.65%), federal withholding (12%), and state withholding (8.75%). To do this, you would multiply your gross pay by the percentage for each deduction and then subtract that amount from the gross pay. Your final paycheck would be $1140 - $87.41 (FICA) - $136.8 (federal withholding) - $100.65 (state withholding) = $815.34. To record this in your register, you would add $815.34 to your current balance, which would bring your new balance to $1314.33
On October 24, you buy $78.54 in clothes from FitRight and pay 6% sales tax. To calculate the sales tax, you would multiply $78.54 by 0.06 and add that amount to the total cost of the clothes. The total cost of the purchase including sales tax would be $78.54 + $4.71 = $83.25. To record this in your register, you would subtract $83.25 from your current balance, which would bring your new balance to $1231.08
The balance as of October 24 would be $1231.08

Resizing or changing an object is the process of dilation. Through the use of the specified scale factor, it is a transformation that reduces or enlarges the objects.
What is Dilation Geometry?The pre-image refers to the original figure and the new figure that results from dilation is known as the image. Two forms of dilation exist:An object's size expands when it undergoes expansion.When an object gets smaller, the process is called contraction.The following illustration, which depicts a square dilating, should be noted. However, the square's shape doesn't change; rather, its size is raised.In mathematics, dilation is the process of modifying an object's or shape's size without altering its shape. The form could be a point, a section of a line, a polygon, etc. It should be noted that while the shape can be altered in size, the proportions of its various dimensions and angles never change.The angles are the same when PQR is increased to P'Q'R. After dilatation, the vertices of the PQR have new coordinates.P(1,3) → P' (3,9) (3,9)
Q(3,1) → Q' (9,3) (9,3)
R(1,1) → R' (3,3) (3,3).

Nicole cycled 9 laps on a bicycle path around the lake. If each lap was 9540ft long, what was the total distance she cycled? Write your answers in miles.
Answer:
162 miles.
Step-by-step explanation:
To find the total distance Nicole cycled, we can multiply the number of laps by the length of each lap.
The total distance Nicole cycled is:
9 laps * 9540 ft/lap = 858,600 ft
To convert this distance to miles, we can use the conversion factor that there are 5280 feet in a mile.
858,600 ft / 5280 ft/mile = 162 miles
So the total distance Nicole cycled is 162 miles.

The annual salary of the man is Rs 780,000 and his total taxes is given by the relation T = Rs 9,000
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Since the man's monthly salary is Rs 65,000, his annual salary would be:
Annual salary = Monthly salary x 12
Annual salary = 65,000 x 12
Annual salary = 780,000
His annual salary of Rs 780,000 falls in the third tax bracket which is from 750,001 to 2,000,000.
So, the tax rate applicable to him would be 30%.
To calculate the amount of tax he would have to pay, we can use the formula:
Tax amount = Tax rate x Taxable income
where taxable income is the income above the lower limit of the tax bracket.
In this case, the taxable income would be:
Taxable income = Annual income - Lower limit of tax bracket
Taxable income = 780,000 - 750,001
Taxable income = 29,999
So, the amount of tax he would have to pay would be:
Tax amount = 30% x 29,999
Tax amount = 8,999.7
Rounding this to the nearest rupee gives us:
Tax amount = Rs 9,000
Hence , the man would have to pay Rs 9,000 in taxes on his annual salary of Rs 780,000.

how do find the factors of a fraction Example 3 1/2 (unit rate, proportionality)
The factors of a fraction 3 1/2 is 3/2.
What are the factors?Generally, A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another number to generate n. Another name for this concept is a factor of n. One may also state that n is a multiple of m in this particular scenario.
Since 3/2 is a fraction, it does not have any factors since factors are integers that may evenly divide a number. Since 3/2 is a fraction, it does not have any factors. Only integers are capable of having factors; fractions are unable to do so.
To find the factors of a fraction, you can factor the numerator and denominator separately.
In the case of 3 1/2, the numerator 3 is a prime number and cannot be factored further.
However, the denominator 2 can be factored as 2 x 1.
Therefore, the factors of 3 1/2 are: (3 x 1) / (2 x 1),

The value 2(-7) is interpreted that a location that is twice as far below sea level as the dolphin. Option A is the correct option.
What is the meaning of interpretation?
Elucidate, explain, explicate, and expound are some synonyms for interpret. While all of these words mean "to make something clear or understandable," interpretation adds to explain why dealing with something requires imagination, sympathy, or special knowledge.
Given that sea level is defined as having an elevation of 0. A dolphin is 7 meters below sea level.
If the level is below sea level, then it can represent by a negative number.
The statement "A dolphin is 7 meters below sea level." can be written as:

The sides of MNPQ are represented by the expressions below. Find the perimeter of MNPQ.
MW=-2+37
QP= y+14
NP= x-5
MN=4y+5
perimeter: ? units
Answer:
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of all its sides. To find the perimeter of MNPQ, we need to add up the lengths of MN, NP, PQ and PM.
Given that:
MW=-2+37 = 35
QP= y+14
NP= x-5
MN=4y+5
The perimeter can be calculated by adding up the above expressions:
Perimeter = MN + NP + QP + MW
= (4y + 5) + (x - 5) + (y + 14) + 35
= 4y + x + y + 54
= (4y + y) + (x + 54)
= 5y + x + 54
So the perimeter of MNPQ is 5y + x + 54 units.
what is 36 percent of 128
Answer:
Step-by-step explanation:
36 percent can be written as 36/100. So now the question is 36/100 x 28.
Its easier if you simplify 100 and 28 by a common factor, which im going to use 4 for. So instead you get 36/25 x 7.
36x7=252
252/25=10.08
Answer:
46.08
Step-by-step explanation:
Remember that a percent is always a fraction out of 100, in this case 36/100, so it can also be written as a decimal number, in this case 0.36. Now all you need to do is multiply 128*0.36
factor: x^2 -x -2

A function f(x)=^3√x is transformed into the function g (x) = 2^3√x-4+5. Name and explain in
complete sentences the transformations that occurred to the parent cube root function.
The required transformations are
f(x) is shifted 5 units to the right andf(x) is shifted 5 units upWhat is function?A function is a mathematical equation which shows the relationship between two variables.
What is transformation?Transformation is the performing of the mathematical operations of dilation, translation, relection and rotation on a function.
How to describe the transformation?Given the function [tex]f(x) = 2^{3\sqrt{x} }[/tex] which is transformed into the function [tex]g(x) = 2^{3\sqrt{x - 4}} + 5[/tex], we describe the transformations as follows.
First Since we have x - 4, [tex]f(x) = 2^{3\sqrt{x} }[/tex] is shifted four units to the right. So, we have , [tex]g(x) = 2^{3\sqrt{x - 4}}[/tex].
Also, since 5 is added to [tex]g(x) = 2^{3\sqrt{x - 4}}[/tex]. [tex]g(x) = 2^{3\sqrt{x - 4}}[/tex]. is shifted 5 units up to get [tex]g(x) = 2^{3\sqrt{x - 4}} + 5[/tex],
So, the required transformations are

A landscaping business is purchasing plants from a nursery to finish a project. It will
cost $14 each to buy each tree and $7 each to buy each bush. The landscaper wishes to
keep the spending to no more than $870. Let t be the number of trees and b be the
number of bushes.
Select the inequality that describes the situation.
14t+7b> 870
O 14t+ 76 2 870
O 14t+7b < 870
O 14t+7b ≤ 870
I think it is the third answer.
Because your problem says 'no more than' so it can't be the fourth one,because it has '≤' which means that the number is lower or equal.
So it is the third one.
Hope I helped you!
