Answer:

y = 3.5

Step-by-step explanation:

0.5y - 2 = 0.25x ( add 2 to both sides )

0.5y = 0.25x + 2 ( divide through by 0.5 )

y = 0.5x + 4

when x = - 1 , then

y = 0.5(- 1) + 4

  = - 0.5 + 4

  = 3.5

Answer:

Step-by-step explanation:

step 1.  0.5y-2=0.25x

step 2 0.5 y-2=0.25(-1)

step 3 0.5y = 1.75

step 4 y = 3.5

Yes, it is true that the functional baseline identifies all top-level functions that a system must carry out as well as the functionality that is expected of it.

The functional baseline describes the system functionality that is necessary, as well as the functional and interface features of the overall system and the verification that is necessary to show that the given functional characteristics have been achieved. An activity's effectiveness and progress can be tracked and evaluated both during implementation and after completion using the data from a baseline study as a benchmark.

The functional baseline is the authorized configuration documentation that details a system's or top-level CI's performance requirements (functional, interoperability, and interface characteristics), as well as the verification necessary to show the accomplishment of those specified characteristics.

Answer:

7.5 Hours

Step-by-step explanation:

Given:

Kellan burns 348 calories in 3 hours.

Question:

How long will it take her to burn 870 calories?

Solve:

Since, it given that KelIan burns 348 calories in 3 hours. Then we need to find how much KeIlan burns per hour.

To do that, divide the calories by the hours.

Thus, 348 divided by 3 which equals 116.

Now knowing that KeIlan burns 116 per hour will help us know how much hours it would take to burn up 870 calories.

To do that,

We have to divide 870 by 116 which equals 7.5.

Hence, it would take 7.5 hours to burn 870 calories.

Michael can jump 31 inches high. This can be calculated by subtracting his height (63 inches) from the height of the doorframe (94 inches), which gives a difference of 31 inches.

The tangent is horizontal when the slope of the tangent is 0.

A horizontal tangent line is a mathematical feature on a graph, located where a function's derivative is zero.

Where the derivative of a function is zero, a graph's horizontal tangent line is a mathematical feature.

This is so that the derivative, by definition, can provide the slope of the tangent line.

The slope of horizontal lines is zero. As a result, the tangent line is horizontal when the derivative is zero.

Use the function's derivative to get the zeros and then insert them back into the original equation to find horizontal tangent lines.

Calculus considers horizontal tangent lines significant because they show local maximum or minimum points in the original function.

On solving the provided question we cans ay that - the value of the following exponent is [tex]10^-5[/tex]

Exponentiation, often known as "b raised to the nth power," is a mathematical operation denoted by the symbol bn that involves two numbers: a base number, b, and an exponent, or power, n. Exponents show how many times a number has been multiplied by itself. As an illustration, 2-3 (written as 23) denotes: 2 x 2 x 2 = 8. 23 is not equivalent to 2 + 3 = 6. Recall that an integer raised to the power of one equals itself. A approach to express huge numbers as powers is through the use of exponents. Exponent, then, is the quantity that indicates how many times a number has been multiplied by itself. As an illustration, 6 is multiplied by 4 to provide 6 x 6 x 6 x 6.

The equation provided in the problem is a parabola whose maxima is at (6, 36)

To determine the equation of a parabola, we can utilize the vertex form. Assuming we can read the coordinates (h,k) from the graph, the aim is to utilize the coordinates of its vertex (maximum point, or minimum point), to formulate its equation in the form y=a(x-h)²+k, and then to determine the value of the coefficient a.

Given that an equation y = 12x - x² where x represents the length of the side of the patio and y represents the area of the patio.

Since the given equation is parabolic it must have a maxima point

dy/dx = 12-2x

for maximum point dy/dx = 0

Thus,

12 - 2x = 0

x = 6

substituting this value in the function

f(x) = 12*6 + 6*6

f(x) = 36

Therefore, (6, 36) points are the maxima point of the given parabolic function. These given points show that the patio will have a maximum area at the length of 6.

To find the percentage of VAT that can be added to the customer purchase price after the discount, you can use the following formula:

VAT% = (MP - (MP * (discount%/100))) / ((MP * (discount%/100)) * (1 + (VAT%/100))) * 100

Plugging in the values you provided, we get:

VAT% = (500 - (500 * (11.5/100))) / ((500 * (11.5/100)) * (1 + (VAT%/100))) * 100

Solving for VAT%, we get:

VAT% = 15.384615384615385

Therefore, you can add 15.384615384615385% VAT to the customer purchase price after the discount so that the Multiplug can be obtained for the same amount as the marked price.

An average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

how to calculate the average(avg) = sum of all terms/number of terms.

According to the question:

Mariella had compared 9 brands later on she wanted to even compare the other 2 brands so the average has to be calculated to 11 brands (9+2).

We can formulate it as (292 +282+ 9*254)/11

The base number is multiplied by itself the number of times indicated by the exponent. In this example, the base number (2) is multiplied by itself 4 times, resulting in 16. Exponential form is often used to express large numbers in a more compact form. It is also used to represent scientific notation, which is a way to write very large or very small numbers in a convenient form. Exponential form can also be used to represent repeated multiplication. For example, 2^4 represents 2 multiplied by itself 4 times.

What is a linear system of equations?

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The  system of equations are:

x + 3y = 7 ---(1)

2x + 4y = 9---(2)

From equation (1), we have x=7-3y

So, substitute x=7-3y in equation (2), we get

2 × (7-3y)+4y=9

⇒ 14-6y+4y=9

⇒ 14-2y=9

⇒ 2y=5

⇒ y=2.5

Substitute y=2.5 in equation (1), we get

Answer:

y = 8x + 2.99

y =10.99x  if the shipped was charger per shirt.

Step-by-step explanation:

For the first equation, the shipping charge in 2.99 if you buy 1 shirt or 100 shirts.  It is an initial or one time fee, but you have to pay $8 for each shirt.  I shirt 8, 2 shirts 16, 3 shirts 24 and so on.

In the second equation you are paying 2 and the shipping for each shirt.

That function is when the shipping charge is a one time fee.

If the shipping charge applied to each sweatshirt, then the total cost function would be y = 10.99x

===================================================

Explanation:

x = number of sweatshirts

Since each shirt costs $8, the expression 8x is the total cost of the shirts if we ignore shipping. Add on shipping to get 8x+2.99 as the actual total cost. This wouldn't include taxes or any other potential fees.

Adding on the 2.99 means it's a one time charge. This assumes all of the sweatshirts you buy is able to be shipped in one box.
---------------

If we changed it so that the shipping applied to each shirt (instead of each box), then the 2.99 would become 2.99x

That would mean the total cost becomes y = 8x+2.99x which fully simplifies to y = 10.99x

It says that the cost per shirt is really $10.99
