Answer:

195

Step-by-step explanation:

Answer:

The equation is y=mx+b in this case the b represents the y int and does not aid in detemining steepness. To determine the steepest, the value of m (or the slope) rise/run must be either the most positive number or the most positive negative. in this case you have 2/1 , 7/1. 5/1.

So y==7x+3 has the steepest (greatest value)  slope

Step-by-step explanation:

The equation has the greatest slope which is 7, hence the equation of the line y = 7x + 3 is the steepest

The formula for finding the equation of a line is expressed as y = mx + b

m is the slope of the line

b is the y-intercept

The line that will be the steepest must have the largest slope.

Looking at the equation y = 7x +3

Get the slope by comparing to have;

mx = 7x

m = 7

Since the equation has the greatest slope which is 7, hence the equation of the line y = 7x + 3 is the steepest

Based on the information you provided, R(t) is a differentiable function that represents the rate at which people leave a restaurant in people per hour after 6 hours since opening. In other words, R(t) describes the speed at which customers are leaving the restaurant as time goes by.

It's important to note that R(t) is only a function of time t, and not a function of the number of people currently in the restaurant or any other variables. This means that if the restaurant is empty at 6 hours since opening, R(t) will give you the rate at which people leave the restaurant from that point forward, regardless of whether there are any customers in the restaurant or not.

In terms of the restaurant's function, R(t) is a key component in understanding how many customers the restaurant is likely to have at any given time. By subtracting R(t) from the restaurant's initial capacity (i.e. the number of seats or tables available), you can estimate how many customers are likely to be in the restaurant at any given time.

Overall, R(t) is a powerful tool for understanding the behavior of customers in a restaurant and can help the restaurant make informed decisions about staffing, marketing, and other aspects of their business.

120 percent,

because if you divide by 6, you will get 10:12 and if you make the 10 a 100, you multiply both by 10, so 12 x 10 = 120 which means it is 20 percent because you have to subtract 100 from the quantity. so it is 20 percent

Answer and explanation:

When you use positive interger to represent income, it shows that there has been an addition instead of a subtraction in money value to the business. In other words money is coming in instead of going out. Example when there is profit on goods sold say $10, it is indicated with a positive integer 10 to indicate addition in terms of operating income

When you use a negative value to represent expense, it indicates there has been a subtraction instead of an addition in money value. In other words money is going out of the business and not coming in. Example when there is a transportation expense to convey goods to the buyer, it is recorded as expenses subtracted from say revenue sales of the business. expenses are usually indicated in brackets in accounting to show negative value, although not a requirement since they are already named and recognized as expenses and subtracted regardless

Given:

The expression is:

\(\dfrac{25x^2}{2x+6}\cdot \dfrac{2}{5x}\)

To find:

The simple product.

Solution:

We have,

\(\dfrac{25x^2}{2x+6}\cdot \dfrac{2}{5x}\)

It can be written as:

\(=\dfrac{5\times 5\times x\times x}{2(x+3)}\cdot \dfrac{2}{5x}\)

Cancel out the common factors.

\(=\dfrac{5\times x}{x+3}\)

\(=\dfrac{5x}{x+3}\)

Therefore, the correct option is C.

(a) The limit of g(x) as x approaches 4 is 5/42.

(b) The limit lim x->4 (2/(x+3)) - (1/(x+2))/(x-4) is of the form 0/0.

The given problem involves evaluating the limit of the function g(x) as x approaches 4 and analyzing the form of the limit.

Let's address each part separately:

(a) To evaluate the limit lim g(x) as x approaches 4, we substitute x = 4 into the expression of function g(x) and compute the result:

lim g(x) x->4 = lim (2/(x+3)) - (1/(x+2)) x->4 = 2/(4+3) - 1/(4+2) = 2/7 - 1/6 = (12 - 7)/42 = 5/42.

Therefore, the limit of g(x) as x approaches 4 is 5/42.

(b) Now, let's consider the limit lim x->4 (2/(x+3)) - (1/(x+2))/(x-4) and determine the form of the limit.

The limit is of the form 0/0.

This form is called an indeterminate form because it does not provide enough information to determine the value of the limit.

It could evaluate to any real number, infinity, or not exist at all.

Further analysis, such as applying L'Hôpital's rule or algebraic manipulations, is needed to evaluate the limit.

To summarize, the limit lim g(x) as x approaches 4 is 5/42, and the limit lim x->4 (2/(x+3)) - (1/(x+2))/(x-4) is of the form 0/0, indicating an indeterminate form that requires further investigation to determine its value.

The equation of the line(s) normal to the curve y = (2x - 1)^3 with a slope of -1/24 and x > 0 is y = 12x - 6 - (1/6)i.

To find the equation of the line(s) normal to the curve y = (2x - 1)^3 with a slope of -1/24, we can use the properties of derivatives.

The slope of the normal line to a curve at a given point is the negative reciprocal of the slope of the tangent line to the curve at that point.

First, we need to find the derivative of the given curve to determine the slope of the tangent line at any point.

Let's find the derivative of y = (2x - 1)^3:

dy/dx = 3(2x - 1)^2 * 2

      = 6(2x - 1)^2

Now, let's find the x-coordinate(s) of the point(s) where the derivative is equal to -1/24.

-1/24 = 6(2x - 1)^2

Dividing both sides by 6:

-1/144 = (2x - 1)^2

Taking the square root of both sides:

±√(-1/144) = 2x - 1

±(1/12)i = 2x - 1

For real solutions, we can disregard the complex roots. So, we only consider the positive root:

(1/12)i = 2x - 1

Solving for x:

2x = 1 + (1/12)i

x = (1/2) + (1/24)i

Since we are interested in values of x greater than 0, we discard the solution x = (1/2) + (1/24)i.

Now, we can find the y-coordinate(s) of the point(s) using the original equation of the curve:

y = (2x - 1)^3

Substituting x = (1/2) + (1/24)i into the equation:

y = (2((1/2) + (1/24)i) - 1)^3

  = (1 + (1/12)i - 1)^3

  = (1/12)i^3

  = (-1/12)i

Therefore, we have a point on the curve at (x, y) = ((1/2) + (1/24)i, (-1/12)i).

Now, we can determine the slope of the tangent line at this point by evaluating the derivative:

dy/dx = 6(2x - 1)^2

Substituting x = (1/2) + (1/24)i into the derivative:

dy/dx = 6(2((1/2) + (1/24)i) - 1)^2

      = 6(1 + (1/12)i - 1)^2

      = 6(1/12)i^2

      = -(1/12)

The slope of the tangent line at the point ((1/2) + (1/24)i, (-1/12)i) is -(1/12).

To find the slope of the normal line, we take the negative reciprocal:

m = 12

So, the slope of the normal line is 12.

Now, we have a point on the curve ((1/2) + (1/24)i, (-1/12)i) and the slope of the normal line is 12.

Using the point-slope form of a line, we can write the equation of the normal line:

y - (-1/12)i = 12(x - ((1/2) + (1/24)i))

Simplifying:

y + (1/12)i = 12x - 6 - (1/2)i - (1/2)i

Combining like terms:

y + (1/12)i = 12x - 6 - (1/24)i

To write the equation without complex numbers, we can separate the real and imaginary parts:

y = 12x - 6 - (1/12)i - (1/12)i

The equation of the normal line, in terms of real and imaginary parts, is:

y = 12x - 6 - (1/6)i.

If a book has 276 pages and Amina had read 1/3 of the book, then 184 pages are left for Amina to read.

If a book has 276 pages and Amina has already read 1/3 of the book, we need to find out how many pages are left for her to read. To calculate the number of pages Amina has already read, we can multiply the total number of pages by the fraction she has read:

1/3 x 276 = 92 pages

Therefore, Amina has already read 92 pages of the book.

To determine how many pages are left for Amina to read, we subtract the number of pages she has already read from the total number of pages:

276 - 92 = 184 pages

So, there are 184 pages left for Amina to read in the book.

To create a square with 50px sides, we need to draw four lines that are each 50px long and perpendicular to one another.

A square is a quadrilateral (a four-sided shape) with four equal sides and four equal angles of 90 degrees each. To create a square with 50px sides, we need to follow a few steps.

Step 1: Draw a line that is 50px long using a ruler or any other measuring tool.

Step 2: At the end of the line, draw a second line that is also 50px long and perpendicular to the first line. This will form the first side of the square.

Step 3: From the end of the second line, draw a third line that is also 50px long and perpendicular to the second line. This will form the second side of the square.

Step 4: Finally, draw a fourth line that is 50px long and perpendicular to the third line, connecting back to the starting point of the first line. This will form the remaining two sides of the square.

By following these steps, you have successfully created a square with 50px sides.

In summary, a square is a four-sided shape with four equal sides and angles of 90 degrees each. The resulting shape will be a square with 50px sides.

To find the length of the base and height, we need to find the difference in the x-coordinates and the y-coordinates of the opposite corners of the rectangle. The length of the base is found by subtracting the x-coordinate of point H from the x-coordinate of point J, which is 15 - 10 = 5. The height is found by subtracting the y-coordinate of point I from the y-coordinate of point K, which is 7 - (-4) = 11.

The area of the rectangle is found by multiplying the length of the base by the height, which is 5 * 11 = 55.

The perimeter of the rectangle is found by adding up the lengths of all four sides, which is 2 * (5 + 11) = 2 * 16 = 32.

Answer:

Given coordinates, the length of the base can be found by subtracting the x-coordinates of two opposite vertices. In this case, it would be (15 - 10) = 5 units.

The height can be found by subtracting the y-coordinates of two opposite vertices. In this case, it would be (7 - (-4)) = 11 units.

The main difference between q(t) = qmax e^ -t/rc and q(t) = cv (1-e^-t/rc) is in their mathematical form and physical interpretation.

The first equation, q(t) = qmax e^ -t/rc, represents the discharge of a capacitor in an RC circuit, where qmax is the maximum charge that the capacitor can store, t is the time elapsed since the circuit was closed, r is the resistance in the circuit, and c is the capacitance of the capacitor.

This equation describes an exponential decay of the charge on the capacitor over time, with a time constant of rc.

The second equation, q(t) = cv (1-e^-t/rc), represents the charging of a capacitor in an RC circuit, where cv is the initial voltage across the capacitor, t is the time elapsed since the circuit was closed, r is the resistance in the circuit, and c is the capacitance of the capacitor. This equation describes an exponential increase of the charge on the capacitor over time, with a time constant of rc.

Therefore, the main difference between the two equations is that one describes the discharge of a capacitor, while the other describes the charging of a capacitor.

Additionally, the equations have different mathematical forms and use different variables, even though they both involve the time constant rc.
