The amount, a, in Chelsea's savings account after y years can be found using the equation a = 1000(1.03)".
After 5 years, Chelsea sells her car for its current value and adds the money to her savings account. The savings account continues to get the same interest rate as before.
Two years after that, 7 years after initially starting the savings account and buying the car, how much money is in Chelsea's savings account, to the nearest dollar?

Answers

Answer 1

Chelsea has $13,385 in her savings account after 7 years.

What is savings account ?

A savings account is an effective way to store your money in a secure location where it can earn interest.

After 5 years, the amount in Chelsea's savings account will be:

a = 1000(1.03)^5 = 1000(1.159274) = 1159.27

Let's say that Chelsea sells her car for x dollars. She adds that to her savings account, so the new amount in her account is:

1159.27 + x

After two more years (i.e., 7 years after initially starting the savings account), the amount in her savings account will be:

a = (1159.27 + x)(1.03)^2 = (1159.27 + x)(1.0609) = 1232.56 + 1.0609x

To find the value of x, we need to know the current value of the car. Once we have that, we can substitute it into the equation above to find the final amount in Chelsea's savings account.

For example, let's say that Chelsea sold her car for $5000. Then, the final amount in her savings account would be:

a = 1232.56 + 1.0609(5000) = 13384.91

Therefore, to the nearest dollar, Chelsea has $13,385 in her savings account after 7 years.

Step-by-step explanation:

clearly, the price is marked down to $9.60.

so, the 1st and 4th answer options are wrong.

is it marked down by 12% or by 20% ?

the basic price was $12. = 100%

how much are 10% of that ? well, 12/10 = $1.20.

but we marked down by $2.40.

when you compare $1.20 and $2.40, what do to see ?

that the second number is exactly twice the first number.

10%×2 = 20%

therefore, the 3rd answer is correct.

The table shows the number of each color pen in Mrs. Devon's desk drawer. Suppose she selects a pen at random from the drawer. How much greater is the theoretical probability of selecting a black pen than selecting a red or a green pen? Express your answer as a percent. Color Number of Pens Black 9 Blue 6 Green 1 Red 4​

Answers

Answer:

Step-by-step explanation:

Black = 9, Blue = 6, Green = 1, Red = 4

Pr(Black) = 9/18 = 1/2 = 50%

Pr(Red or Green) = 5/18 = 28%

therefore it is 22% (50-28) more likely that Mrs. Devon will select a black pen than a red or green

Answer:

1. 9+6+1+4=20

Black 9/20 = 0.45 = 45%

Red or green = 5/20 = 0.25= 25%

selecting black is 45-25 = 20%

What is law of sines ?

The Law of Sines, also known as the Sine Rule, is a formula used to find unknown angles or sides of a triangle, given some combination of angle and side measurements. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. Mathematically, the Law of Sines can be expressed as follows:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the angles opposite those sides, respectively.

Given by the question:


To find x, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides.

Let's use the sine function to find the length of side AB:

sin A / AB = sin C / BC

sin 45 / x = sin 40 / 12

Rearranging and solving for x:

x = sin 45 * 12 / sin 40

x ≈ 9.05 cm

Therefore, the length of side x is approximately 9.05 cm.

(i) Find an expression for the length of each side of the square bottom. (ii) Use the function to find the volume of a cage with a height of 18 inches. (iii) Use the remainder theorem to find the volume of a cage with a height of 15 inches

Answers

The remainder theorem can be used to determine the volume of a cage with a 15-inch height since b = 15, which results in a volume of 2160 inch3.

what is volume ?

The size of an item in 3 directions is the area that is covered by its boundaries. The amount of room an object occupies in three aspects is measured by its height, which is given in cubic inches. A few of illustrations of cubic units are cm3 and in3. On the other perspective, an item's mass is used to measure what more matter it contains. The typical method to ascertain an object's mass is to weigh it, either in pounds or kilograms. Unlike the fundamental equations for the area of a rectangular box, which is length, breadth, and height, the primary equation for volumes is length, width, and height.

given

Height is listed as b and is 18 inches.

B = 18 s= b-3 (from I = 18 - 3 s = 15 as a result.

Therefore, volume

volume of a rectangle = l x b x h V= 18 x 15 x 15 = 4,050 inch3

3) Height = 15 then b = 15 b -15 = 0 if height = 15.

The remaining theorem's definition is:

To get a smaller polynomial and a remainder, we divide a polynomial P(x) by the factor (x - a). The polynomial does not have to contain the factor.

Group 1: 1, 2, 5, 8, -4

Group 2: -2, -4, 5, 8, 2

To check that the two groups have the same sum, we can add up the values of each group:

Group 1 sum: 1 + 2 + 5 + 8 - 4 = 12

Group 2 sum: -2 - 4 + 5 + 8 + 2 = 9

We can see that the sum of Group 1 is 12, and the sum of Group 2 is 9. However, we want the sums to be the same. We can make them the same by adding 3 to the sum of Group 2, which gives:

Group 1 sum: 12

Calculate the mean, Variance and Standard deviation of the age of 12 student 16, 17, 18, 16/0.5, 17, 18, 19, 17, 17, 13, 17/½/2 and 16​

Answers

The mean age of the 12 students is approximately 17.02 years, the variance is 37.41, and the standard deviation is approximately 6.117 years.

What is Statistic?

The statistic is the study of mathematics that deals with relations between comprehensive data.

Here,
To calculate the mean, variance, and standard deviation of the ages of the 12 students, we first need to find the sum of the ages:

Sum = 16 + 17 + 18 + (16/0.5) + 17 + 18 + 19 + 17 + 17 + 13 + (17/2/2) + 16

= 16 + 17 + 18 + 32 + 17 + 18 + 19 + 17 + 17 + 13 + 4.25 + 16

= 204.25

Mean = Sum / Number of students = 204.25 / 12 ≈ 17.02 years

To calculate the variance, we need to subtract the mean from each age, square the differences, add up the squares, and divide by the number of students minus one:

Variance = [ (16 - 17.02)² + (17 - 17.02)² + ... + (16 - 17.02)² ] / (12 - 1)

= [ 0.16 + 1.96 + ... + 0.16 ] / 11

= 37.41

Finally, we can calculate the standard deviation by taking the square root of the variance:

Standard deviation = √(Variance) ≈ 6.117

Therefore, the mean age of the 12 students is approximately 17.02 years, the variance is 37.41, and the standard deviation is approximately 6.117 years.

The cost of packing a box of chocolates is given by 1/4 x2, where x is the number of chocolates (a box can never have fewer than 3 chocolates). If the weight of a box of chocolates is given by x + 2, what is the cost of packaging per weight unit?

Answers

Using the unitary method, we found that the cost of packing the unit weight of the chocolate box is  [tex]\frac{x^2}{4(x+2)}[/tex] , for x ≥ 3.

What is meant by the unitary method?

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, and then multiplying that value to determine the required value. Recognizing the units and values is crucial when using the unitary technique to a problem.

Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

Given,

  The cost of packing a box of chocolates = 1/4 * x²

 where x  = Number of chocolates and x ≥ 3 for one box.

Weight of a box of chocolates = x + 2

We are asked to find the cost of packing 1 unit weight of chocolates.

This can be found using the unitary method.

Cost of unit weight = Cost of packing a whole box / Total weight of the box.

                                = (1/4 * x²) / (x + 2)

                                 = [tex]\frac{x^2}{4(x+2)}[/tex] , for x ≥ 3

Now in the figure below, we are given four options.

On solving the first option we get the above equation as follows.

[tex]\frac{1}{4} x - \frac{1}{2} + \frac{1}{x+2}[/tex]  

Taking LCM and making the same denominator for all.

[tex]\frac{x(x+2) - 2(x+2) +4 }{4(x+2)} = \frac{x^2+2x-2x-4+4}{4(x+2)} = \frac{x^2}{4(x+2)}[/tex]

Answers

Using third-order Newton's interpolating a polynomial the value of f(2) is  (25ln(2))/9.

What is the value of f(2)

To estimate the value of f(2) using a third-order Newton's interpolating polynomial with the given data points, we first need to calculate the divided differences. The divided differences are defined as:

f[xi] = f(xi) for i = 1, 2, 3

f[x1,x2] = (f[x2] - f[x1]) / (x2 - x1) = (ln(4) - ln(1)) / (4 - 1) = ln(4) / 3

f[x2,x3] = (f[x3] - f[x2]) / (x3 - x2) = (ln(6) - ln(4)) / (6 - 4) = ln(3) / 2

f[x1,x2,x3] = (f[x2,x3] - f[x1,x2]) / (x3 - x1) = ((ln(3) / 2) - (ln(4) / 3)) / (6 - 1) = -0.018

Using these divided differences, we can write the third-order Newton's interpolating polynomial as:

f(x) = f[x1] + f[x1,x2](x - x1) + f[x1,x2,x3](x - x1)(x - x2) + f[x1,x2,x3,x4](x - x1)(x - x2)(x - x3)

Substituting the values of the data points and the divided differences we calculated, we get:

f(x) = ln(1) + ln(4)/3 (x - 1) - 0.018 (x - 1)(x - 4)

Simplifying this expression, we get:

f(x) = ln(1) + (ln(4)/3)x - (11ln(2)/9) + (ln(2)/9)x^2

To estimate f(2), we plug in x = 2:

f(2) = ln(1) + (ln(4)/3)(2) - (11ln(2)/9) + (ln(2)/9)(2)^2

f(2) = 2ln(2) - (11ln(2)/9) + (ln(2)/9)(4)

We need to find, reasonable domain to plot the growth function, the y-intercept of the graph of the function f(m) to represent and average rate of change of the function f(m) from m = 1 to m = 9,

f(m) = [tex]3(1.09)^{m}[/tex]

m = 0

f(0) = 3(1.09)⁰  = 3 cm

The length of the fish was approximately 5.98 cm.

5.98 = [tex]3(1.09)^{m}[/tex]

1.99 = [tex](1.09)^m[/tex]

m = 8

Reasonable domain to plot the growth function = [0, 8]

The y-intercept of the graph of the function f(m) represent initial length of fish = 3 cm

The average rate of change of the function f(m) from m = 2 to m = 8

m = 2, f(2) = 3(1.09)² = 3.56  cm

m = 8, f(8) = 3(1.09)⁸ = 5.97 cm

A company has recently been hiring new employees. Today the company has 36% more employees than it did a year ago. If there are currently 44200 employees, how many employees did the company have a year ago?

Answers

The company had 32,500 employees a year ago.

According to given information :

Let x be the number of employees the company had a year ago.

According to the problem, the company now has 36% more employees than it did a year ago. This can be expressed mathematically as:

x + 0.36x = 44200

Simplifying the left-hand side of the equation:

1.36x = 44200

Dividing both sides by 1.36:

x = 32500

Therefore, the company had 32,500 employees a year ago.

What is percentage ?

Percentage is a way of expressing a portion or part of a whole as a fraction of 100. It is often represented by the symbol "%".

For example, if 20 out of 100 students in a class are absent, we can say that the percentage of absent students is 20%. This means that 20 out of every 100 students in the class are absent.

To calculate a percentage, you divide the part by the whole and multiply by 100. For example, if 30 out of 50 students passed a test, the percentage of students who passed the test is:

(30 ÷ 50) × 100 = 60%

This means that 60 out of every 100 students in the class passed the test.

A person invested $13,000, part of the money, x, was placed in a stock that paid 9% annual interest. The rest of the money suffered a 5% loss. Express the total annual income from both investments, I, as a function of x.

Answers

The total annual income from both investment is

(14x -65000)/100

What is interest?

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

I = x× 9/100

I = 9x/100

(13000 - x) × 5/100

= (65000-5x)/100

therefore the total amount annual income

= 9x /100 - (65000-5x)/100

= (9x+5x-65000)/100

= (14x - 65000)/100

therefore the total annual income = (14x -65000)/100

In a case whereby a  person invested $13,000, part of the money, x, was placed in a stock that paid 9% annual interest the total annual income from both investments, I, as a function of x is I= [ 0.14X+12350 ]

How can the  total annual income from both investmentsbe expressed?

The Amount that was invested =$13,000

Then the Profitable Investment which was givden as 9% can be expressed as =  [ X(1.09) ]

Then from the question we can see the Negative Investment, which is -5% and can be expressed as = [ (13,000-X)(1-0.05) ]

The we can sum up as

I= [ X(1.09) ]+ [ (13000-X)(0.95) ]

This can be simplified as

I= [ 1.09X-0.95X+12350 ]

I= [ 0.14X+12350 ]

Describe Triangles?

A triangle is a closed geometric figure that is formed by connecting three straight line segments called sides. These sides meet at three points called vertices. Triangles are one of the simplest and most fundamental shapes in geometry and can be found in many natural and man-made objects.

Triangles can be classified into different types based on their sides and angles.

By sides:

Equilateral triangle: all three sides are equal in length.

Isosceles triangle: two sides are equal in length.

Scalene triangle: all three sides are different in length.

By angles:

Acute triangle: all three angles are acute (less than 90 degrees).

Right triangle: one angle is a right angle (exactly 90 degrees).

Obtuse triangle: one angle is an obtuse angle (greater than 90 degrees).

Triangles have many properties and are used in various fields such as architecture, engineering, physics, and mathematics. They are also commonly used in trigonometry to solve problems involving angles and distances.

We can use the property of similar triangles to solve this problem.

First, let's label the intersection point of FG and BC as point H. Also, let's label the length of CG as x.

Since FG is parallel to AC, we can use the property of similar triangles to find that triangles ABF and HBG are similar.

Therefore, we can set up the proportion:

AB/FB = HG/GB

Plugging in the given values, we get:

10/63 = (x + 57)/57

Solving for x, we get:

x = 5.4

Therefore, the length of CG is approximately 5.4 units.

The value of the variable x and y will be 1.5 and -2.5, respectively. Then the value of the expression (x + y) will be negative 1.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

here, we have,

A system of equations is given below.

x = -2y - 3.5       ...1

-5x + 3y = -15    ...2

From equations 1 and 2, then we have

-5(-2y - 3.5) + 3y = -15

10y + 17.5 + 3y = - 15

13y = -32.5

y = - 2.5

Then the value of the variable 'x' is calculated as,

x = - 2(-2.5) - 3.5

x = 5 - 3.5

x = 1.5

Then the value of the expression (x + y) is calculated as,

x + y = 1.5 + (-2.5)

x + y = 1.5 - 2.5

x + y = - 1

Answer:

Step-by-step explanation:

We can start by combining the two fractions by finding a common denominator:

sin(a)/(1+cos(a)) + (1+cos(a))/sin(a)

= sin^2(a)/(sin(a)(1+cos(a))) + (1+cos(a))^2/((1+cos(a))sin(a))

= sin^2(a) + (1+cos(a))^2 / (sin(a)(1+cos(a)))^2

= (sin^2(a) + 1 + 2cos(a) + cos^2(a)) / (sin^2(a) + 2sin(a)cos(a) + cos^2(a))

= (2 + 2cos(a)) / (sin(a) + cos(a))^2

= 2(1+cos(a)) / (sin(a) + cos(a))^2

= 2(cos^2(a/2)/sin^2(a/2)) / (sin(a/2) + cos(a/2))^2 (using the half-angle identities)

= 2tan^2(a/2) / (sin(a/2) + cos(a/2))^2

What is the liquid range of water?

The liquid range of water refers to the temperature range at which water exists as a liquid. At standard atmospheric pressure (1 atm), the liquid range of water is from 0 degrees Celsius to 100 degrees Celsius, or from 32 degrees Fahrenheit to 212 degrees Fahrenheit.

This means that water can exist as a liquid within this temperature range, but if the temperature falls below 0 degrees Celsius or rises above 100 degrees Celsius, it will freeze into a solid or boil into a gas, respectively.
