The approximate distance in feet as a function of the distance in meters is  3.28x + 0.01.

Meters and feet are two different scales for measuring distance. Five meters is approximately 16. 41 ft, and 12 m is approximately 39. 37 ft.

Suppose the approximate distance in feet is y,

and the distance in meters is x

Suppose the function is y = ax + b

Given the information, we can know

S*r_{1} = 5; y_{1} = 16.41

x_{2} = 12

y_{2} = 39.37

S_{0} $ 16.41= 5a +b0 { Substitute }

39.37 = 12a + b*Theta

7a = 22.96

a = 3.28

So 16.41 = 5 * 3.28 + b {Substitute} b = 0.01

So the function is y = 3.28x + 0.01

The approximate distance in feet as a function of the distance in meters is  3.28x + 0.01

For the given frequency table the percent of seniors is 10%.

A frequency table counts the occurrences of each value or range of values in a dataset to organise and summarise the data. It is frequently employed in statistics to give a brief summary of the data and to spot patterns or trends.

The data is initially separated into equal-sized intervals called "classes" in order to construct a frequency table. Following that, a count of the data points belonging to each class is made, and the results are reported in a table manner. Columns for the classes, the frequency (count) of each class, and occasionally the relative frequency or percentage of each class can all be found in the table.

The total frequency is from the given table is:

1 + 2 + 5 + 2 = 10

The frequency of seniors is 1, so the percentage of seniors is:

(1/10) x 100% = 10%

Hence, for the given frequency table the percentage of seniors is 10%.

To calculate how much Gordon will receive from the sale, we need to subtract the expenses and fees from the selling price. Here's a breakdown of the calculations:

Loan Principal: Gordon paid off $280,000 of the loan principal. We subtract this amount from the purchase price:

$750,000 - $280,000 = $470,000 (remaining loan balance).

Realtor Fees: Gordon owes each of the realtors 3.2% of the selling price. This amounts to 3.2% of $1.2 million: 0.032 * $1,200,000 = $38,400.

Buyer's Closing Costs: Gordon offered to cover the buyer's closing costs, which are $5,410.

Loan Payoff: The buyer's loan is $1 million.

To calculate Gordon's net proceeds, we subtract the expenses from the selling price: $1,200,000 - $38,400 - $5,410 - $1,000,000 = $155,190.

Therefore, Gordon will receive approximately $155,190 from the sale of his farm.

The test score is 91.5.

z-score:

A z-score is the number of standard deviations from the mean value of the reference population.

Here we have to find the test score.

Mean(μ) = 90

Standard deviation(б) = 15

z-score = 0.1

Formula for z-score:

z = X - μ / б

Now putting the values in the equation:

0.1 = X - 90 / 15

1.5 = X - 90

X = 91.5

Therefore the test score is 91.5.

Elisabeth would include $3,000 as compensation in her 2020 income as a result of exercising this option.

To determine the compensation Elisabeth should include in her 2020 income as a result of exercising the nonstatutory stock option, we need to calculate the "bargain element" or the difference between the fair market value of the stock on the exercise date and the exercise price.

In this case:

Exercise date: September 4, 2020

Fair market value per share: $45

Number of shares: 100

Exercise price per share: $15

The bargain element per share is the difference between the fair market value and the exercise price:

Bargain element per share = Fair market value - Exercise price

Bargain element per share = $45 - $15 = $30

To calculate the total bargain element, we multiply the bargain element per share by the number of shares:

Total bargain element = Bargain element per share * Number of shares

Total bargain element = $30 * 100 = $3,000

Therefore, Elisabeth should include $3,000 in her 2020 income as compensation resulting from exercising this option.

a) 2-year subscriptions is approximately 20%.

b) 3-year subscriptions is approximately 29.56%.

c) 5-year subscriptions is approximately 41.33%.

To compute the rate of return on the investment for purchasers of different subscription lengths, we need to calculate the average annual cost of each subscription option.

a) 2-year subscriptions:

The cost of a 2-year subscription is $12.00. To find the average annual cost, we divide the total cost by the number of years:

Average annual cost = $12.00 / 2 = $6.00

b) 3-year subscriptions:

The cost of a 3-year subscription is $16.00. To find the average annual cost, we divide the total cost by the number of years:

Average annual cost = $16.00 / 3 = $5.33 (rounded to two decimal places)

c) 5-year subscriptions:

The cost of a 5-year subscription is $22.00. To find the average annual cost, we divide the total cost by the number of years:

Average annual cost = $22.00 / 5 = $4.40

Now, to calculate the rate of return on the investment, we need to compare the average annual cost to the regular 1-year subscription rate of $7.50.

a) For 2-year subscriptions:

Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%

Rate of return = (1 - $6.00 / $7.50) * 100% ≈ 20%

b) For 3-year subscriptions:

Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%

Rate of return = (1 - $5.33 / $7.50) * 100% ≈ 29.56%

c) For 5-year subscriptions:

Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%

Rate of return = (1 - $4.40 / $7.50) * 100% ≈ 41.33%

Therefore, the rate of return on the investment for purchasers of:

a) 2-year subscriptions is approximately 20%.

b) 3-year subscriptions is approximately 29.56%.

c) 5-year subscriptions is approximately 41.33%.

Answer:

D : (0 ≤t ≤6)

R : (-2 ≤d ≤0)

Step-by-step explanation:

your domain is your x and your range is your y.

this means that you start by looking at your x axis. in this problem, x goes from 0 to 6, so 0 ≤t ≤6

this is the same for y.

y goes from -2 to 0 (remember that you read the y axis down and up, so you need to have the negative number written first)  

so -2 ≤d ≤0

Answer:

(domain: 0 ≤ t ≤ 6)

(range: -2 ≤ d ≤ 0)

Step-by-step explanation:

domain of a function: all possible x-values

range of a function: all possible y-values

here, we know that we can't have negative time (note: time is along the x-axis and is x-variable; it is describing the domain)

(and yes, while time still goes on forever, this graph does not have an arrow on the end of it, meaning that is where we are considering time to stop--and because its an ≤ sign, it wouldn't be infinity)

so, time goes from 0 to 6

(domain: 0 ≤ t ≤ 6)

here, we also know that our submarine won't go above the water level (it's not going to keep floating up into space forever), so the maximum value of our range (depth) is going to be 0

we also won't be going any lower than where the toy starts--which we can see to be -2

so, the depth goes from -2 to 0

(range: -2 ≤ d ≤ 0)
