Answer:

The initial cost of Elizabeth's books is $345. After one year, the cost of her books increased by 7%, which is an increase of $345 x 7/100 = $24.15

So, the cost of her books after one year is $345 + $24.15 = $369.15

To find the price of her books after five years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where A is the final amount, P is the initial principal (or starting amount), r is the annual interest rate as a decimal, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $345, r = 7/100, n = 1, and t = 5

So, A = $345 (1 + 7/100)^5 = $345 * 1.07^5 = $475.14

Rounding this to the nearest dollar, we get $475.

Therefore, the price of Elizabeth's books after five years is $475.

Option d has the attributes for the rational function to have asymptotes.

A straight line that continuously approaches a certain curve without ever meeting it is an asymptote.

In other words, an asymptote is a line that a curve travels towards as it approaches infinity.

These asymptotes are visited by the curves, but they are never passed.

From the given question,

f(x) = x²-25/x²-9

So for the values of x where it has asymptotes the required equation or function is as follows:

f(x) = \(\frac{x^2-25}{x^2-9}\)

I'm in class so I'll answer what I can!

1. okay so 25%=40 so to get to 100% we need to multiply 25% by 4 and so we so the same with the number 40x4 equals 160cm

2. so 8k from 20k think of 10k as 50% so it's around 5 per 1k so 8k would be 40% and so 60% would have been spent

3. (I might edit this one later I'm in class :(()

4. so 200cm last year and 240cm this year so it gre by 40cm so it'd be 20% (200=100% so that means it's twice as much as what the % would be!)

5. so 60 is 40% so 30 is 20% so just add up from there 20 x 5 = 100% so 30 x 5 = 150km

0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations

To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

Answer:

1/2

Step-by-step explanation:

First, convert 1 1/3 to improper fraction:

1 1/3 = 4/3

Second, make denominator the same by multiplying 4/3 by 2/2:

4/3 * 2/2 = 8/6

Third, subtract:

8/6 - 5/6 = 3/6

Fourth, simplify:

3/6 = 1/2

The correct answer for the difference between \(1\dfrac{1}{3}\)  and \(\dfrac{5}{6}\)  is  \(\dfrac{1}{2}\) .

Given expression:

\(1\dfrac{1}{3} - \dfrac{5}{6}\)

convert \(1\dfrac{1}{3}\)  to an improper fraction:

\(1\dfrac{1}{3} = \dfrac{3*1 + 1}{3}\)

= \(\dfrac{4}{3}\)

Now, the expression becomes:

\(\dfrac{4}{3} - \dfrac{5}{6}\)

To subtract these fractions,

The common denominator is 6.

Rewrite the fractions with the common denominator:

\(\dfrac{4}{3}*\dfrac{2}{2}\)

= \(\dfrac{8}{6}\)

The expression becomes:

\(\dfrac{8}{6} - \dfrac{5}{6}\)

Subtract, the numerators while keeping the common denominator:

= \(\dfrac{8-5}{6}\)

= \(\dfrac{3}{6}\)

Divide  numerator and denominator by greatest common factor (which is 3):

3 ÷ 3 = 1

6 ÷ 3 = 2

= \(\dfrac{1}{2}\)

The correct answer is for \(1\dfrac{1}{3} - \dfrac{5}{6}\)   is  \(\dfrac{1}{2}\).

A total of 12 sheets of plywood will be used in the construction of the shed.


To construct the storage shed completely out of plywood, a total of 12 sheets of 4 foot by 8 foot plywood will be used.

To determine the number of plywood sheets needed, we need to calculate the surface area of the shed. The surface area is the sum of the areas of all the walls, floor, and roof.

The shed has four walls, each with dimensions 16 feet by 8 feet, giving a total wall area of 4 * (16 feet * 8 feet) = 512 square feet. The floor has dimensions 16 feet by 12 feet, resulting in an area of 16 feet * 12 feet = 192 square feet. The roof has dimensions 12 feet by 16 feet, which also gives an area of 192 square feet.

Adding up the wall area, floor area, and roof area, we get a total surface area of 512 square feet + 192 square feet + 192 square feet = 896 square feet.

Since each sheet of plywood measures 4 feet by 8 feet and covers an area of 4 feet * 8 feet = 32 square feet, the total number of plywood sheets needed is 896 square feet / 32 square feet per sheet = 28 sheets. However, since each sheet is 4 feet by 8 feet, we need to round up to the nearest whole sheet. Therefore, a total of 12 sheets of plywood will be used in the construction of the shed.

Answer and explanation:

Given: Belinda wants to invest $1,000. The table below shows the value of her investment under two different options for three different years:  

Number of years 1 2 3

Option 1 (amount in dollars) 1100 1200 1300

Option 2 (amount in dollars) 1100 1210 1331  

To find:

Part A: What type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2?  

Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years.  

Part C: Will there be any significant difference in the value of Belinda's investment after 20 years if she uses option 2 over option 1?

Solution:

Part A: Linear and exponential functions can be used to describe the value of the investment after a fixed number of years using option 1 and option 2, respectively.  

Part B: (n=n+100) and (n=n+100x) are the functions for each option to describe the value of the investment f(n), in dollars, after n years.  

Part C: Yes, there will be a significant difference of 1900 in the value of Belinda's investment after 20 years if she uses option 2 over option 1.

Part A:

In the case of option 1, the linear function can be used to describe the value of the investment after a fixed number of years. This is because, in option one, the amount increases by a fixed amount every year.

In the case of option 2, the exponential function can be used to describe the value of the investment after a fixed number of years. This is because, in option 2, the amount increase is higher than last year.

Part B:

For option 1, the function is

For option 2, the function is

Here, x is the increase in amount every consecutive year.

Part C:

After 20 years, the amount from option 1 would be 3000 and the amount from option 2 would be 4900. Thus, there is a difference between 1900.

Therefore,

Part A: Linear and exponential functions can be used to describe the value of the investment after a fixed number of years using option 1 and option 2, respectively.  

Part B: (n=n+100) and (n=n+100x) are the functions for each option to describe the value of the investment f(n), in dollars, after n years.  

Part C: Yes, there will be a significant difference of 1900 in the value of Belinda's investment after 20 years if she uses option 2 over option 1.

Answer:

T=12500-0.25y

Step-by-step explanation:

Step one:

given data

The value of the car is $12500.

let the value of the previous year be T

let the number of years be y

25% will be 0.25----this is equivalent to the gradient

The expression for the change in price can be represented linearly using the equation of a straight line,

y=mx+c

but since the price is reducing the expression becomes

y=-mx+c

Now, in this situation the expression for the cost after y years is

T=-(0.25y)+12500

rearrange

T=12500-0.25y

The expression is T=12500-0.25y

In mathematics, "\(a^2\)" denotes the square of a number or variable "a." It is calculated by multiplying "a" by itself.

4For example, if "a" is 5, then a^2 would be 5*5, which equals 25. When "a" represents a positive number, its square is always positive.

If "a" is negative, its square is still positive since a negative multiplied by a negative results in a positive.

In geometrical terms, if "a" represents the length of the side of a square, then a^2 represents the area of that square. This notation is part of the general concept of exponentiation.
