How to subtract decimal numbers?
Subtracting decimals is similar to the usual subtraction of whole numbers. We just need to place the decimal numbers, one below the other, according to their place values along with the decimal point. In some cases the two given numbers are different. If needed, we change the given decimal fractions to like decimal fractions to make the subtraction easier. Two decimals are called decimal fractions if they have an equal number of decimal places.
Now, the weight of Desta's plum-the weight of Eddy’s plum=3.24-3.042
=0.198 ounce
Hence, Desta's plum weighs 0.198 ounces more than Eddy’s plum.
estimated work cost [it is a time-dependent variable cost related to manpower project resources and the time they are utilized. equipment when associate with time usage (i.e., hourly rentals) is also classified as work.]
The total estimated work cost for the project would be $5200 ($5000 + $200).
The formula for calculating the estimated work cost for a project is C = P x T, where C is the estimated cost, P is the hourly rate of the personnel and T is the total amount of time spent working on the project. For example, if the hourly rate of a project manager is $50 and they work 100 hours on the project, the estimated work cost would be $5000 (50 x 100). In addition, any equipment that is used on an hourly rental basis should also be included in the estimated work cost calculation. For example, if a piece of equipment is used for 10 hours at a rate of $20 per hour, the estimated cost for this equipment would be $200 (20 x 10). Therefore, the total estimated work cost for the project would be $5200 ($5000 + $200).

Provide the equation of all vertical line that violate the vertical line test. Please help
The vertical line that violates the vertical line test is given as follows:
x = -3.
When does a relation represents a function?A relation represents a function when each input value is mapped to a single output value.
For the relation graphed, we have that at x = -3, there are two closed bounds of the function, meaning that the input x = -3 is mapped to multiple outputs and thus the relation is not a function.
This also means that a vertical line traced at x = -3 would cross the graph of the function at two points, thus violating the vertical line test.

A rectangular paperboard measuring 26 in long and 20 in wide has a semicircle cut out of it, as shown below. What is the perimeter of the paperboard that remains after the semicircle is removed?
The perimeter of a two-dimensional shape is the distance around the shape. In this case, the paperboard has a semicircle cut out of it, so the perimeter of the paperboard that remains after the semicircle is removed is the distance around the remaining rectangular shape.
To calculate the perimeter of the remaining rectangular shape, you can use the formula: 2(length + width) = 2(26 in + 20 in) = 2(46 in) = 92 in.
It is important to note that the perimeter is a measure of the distance around a two-dimensional shape and it doesn't take into account the area inside the shape. Also it is measured in units, in this case inches.

Question:
(a) Find the equation for the family of linear functions with slope 2 and sketch several members of the family.
(b) Find an equation for the family of linear functions such that f(2)=1 and sketch several members of the family.
(c) Which functions belong to both families?
Slope-intercept form
Equation of slope-intercept form is given as y=mx+b where m is the slope of the line and c is the y-intercept. m is used to measure the steepness of the graph. This form is simply the method of writing the equation of a line so that the slope and y-intercept are rapidly apparent.
For a family of linear functions with slope 2, the equation is y = 2x + b, where b is the y-intercept. For a family of linear functions such that f(2) = 1, the equation is y = x + b, where b is the y-intercept. Both families of linear functions have the same equation, y = x + b, and all functions belonging to both families have a slope of 1 and a y-intercept of b.
(a) The equation for the family of linear functions with slope 2 is y = 2x + b, where b is the y-intercept. To sketch several members of the family, plot several points (x, y) with the equation, then connect the points to form a line.
(b) The equation for the family of linear functions such that f(2) = 1 is y = x + b, where b is the y-intercept. To sketch several members of the family, plot several points (x, y) with the equation, then connect the points to form a line.

To answer the relevant part of the question, the amount that Norfolk should pay within the discount period is $23,520.
What is the discount period?The discount period is based on the credit terms.
For instance, 2/10, n/30 show the discount and credit terms. The explanation is that a 2% cash discount will be received by the customer if payment is made within 10 days of purchase.
Furthermore, the customer's credit period expires after 30 days. Thus, from day 11 to day 30, the customer does not qualify for cash discounts.
The catalog list price = $40,000
Trade discount = 40%
Discounted price = $24,000 ($40,000 x (1 - 40%)
Cash discount = $480 ($24,000 x 2%)
Cash payment = $23,520 ($24,000 - $480)
Thus, Norfolk Sporting Goods will pay $23,520 if it utilizes the discount.

There are integers b, c for which both roots of the polynomial x^2-x-1 are also roots of the polynomial x^5-bx-c. Determine the product bc.
It is discovered that the phrase under the division symbol is 3x2 - (b - 2)x - c, meaning that b = 5 and c = 3.
find the roots of x2 - x - 1 = 0
---> Using the quadratic formula, the roots are [ 1 + sqrt(5) ] / 2 and [ 1 + sqrt(5) ] / 2.
Placing these values into the equation x5 - bx - c = 0, we get:
x = [ 1 + sqrt(5) ] / 2 ---> ( [ 1 + sqrt(5) ] / 2 )5 - b( [ 1 + sqrt(5) ] / 2 ) - c = 0
---> [ 176 + 80sqrt(5) ] / 32 - ( [ 1 + sqrt(5) ] / 2 )b - c = 0
multiplying by 32 ---> 176 + 80sqrt(5) - 16b - 16sqrt(5)b - 32c = 0
Using the same steps for x = [ 1 - sqrt(5) ] / 2 , we get: 176 - 80sqrt(5) - 16b + 16sqrt(5)b - 32c = 0
Now, let's combine these two results: 176 + 80sqrt(5) - 16b - 16sqrt(5)b - 32c = 0
176 - 80sqrt(5) - 16b + 16sqrt(5)b - 32c = 0
Subtract the lower equation from the upper: 160sqrt(5) - 32sqrt(5)b = 0 ---> 160sqrt(5) = 32sqrt(5)b ---> b = 5
Now, substitute this value for b into 176 + 80sqrt(5) - 16b - 16sqrt(5)b - 32c = 0
--->176 + 80sqrt(5) - 16(5) - 16sqrt(5)(5) - 32c = 0
--->176 + 80sqrt(5) - 80 - 80sqrt(5) - 32c = 0
--->96 - 32c = 0

You invest $1,200 that is compounded continuously at 9% for 10 years. What is the equation you use?
Answer:
FV = $1,200 * e^(0.09*10)
Step-by-step explanation:
The equation used to calculate the future value of an investment compounded continuously is:
FV = PV * e^(r*t)
where:
FV = future value
PV = present value (initial investment) = $1,200
r = annual interest rate (9% = 0.09)
t = number of years (10 years)
So, the future value of the investment would be:
FV = $1,200 * e^(0.09*10)

For the function ƒ(x) = 2 (x − 10)² + 6 then F⁻¹ = [tex]\frac{x- 6}{2}[/tex] + 10 is the inverse of the given functions.
Calculating the problem:y = [tex]\frac{x - 6}{2}[/tex] + 10
F⁻¹ = [tex]\frac{x -6 }{2}[/tex] + 10
Inverse functions:A function that is capable of reversing into another function is referred to as an inverse function or anti function. Simply put, if a function is denoted by "f" or "F," then the inverse function is denoted by "f-1" or "F-1." The inverse function returns the original value for which a function provided the output.
If any function "f" takes x to y, then the inverse of "f" will take y to x. A function that consists of its inverse retrieves the original value when considering functions, where f and g are inverses, and f(g(x)) = g(f(x)) = x. Then, the opposite of f(x) is g(y) = (y-5)/2 = x.
How is the inverse of a function or relationship determined?The equation of the inverse relation can be obtained by substituting every y in the equation for every x in the equation that describes the relation between the variables x and y.

Which of the following would produce a new confidence interval with larger width (larger margin of error) based on these same data? (a) Use a larger confidence level. (b) Use a smaller confidence level. (c) Increase the sample size. (d) Use the same confidence level, but compute the interval n times. Approximately 5% of these intervals will be larger. (e) Nothing can guarantee absolutely that you will get a larger interval. One can only say that the chance of obtaining a larger interval is 0.05.
Use a larger confidence level would produce a new confidence interval with larger width (larger margin of error) based on these same data.
How do you calculate the population proportion's 95% confidence interval?
We must determine p′ and q′ in order to construct the confidence interval. p′ = 0.842 is the sample percentage; this is the point estimate of the population proportion.
Since CL = 0.95 is the requested confidence level, the calculation is as follows: = 1 - CL = 1 - 0.95 = 0.05 ( 2) ( 2) = 0.025.
