Answer:

B. 336. 38

Step-by-step explanation:

So, what you want to do is multiply the original price ($299) by the first markup percentage (150%)

299*1.50= $448.50

that is your markup price!

then you have to do the sale % (25%)

so you'll multiply your (25%) by your new price ($448.50)

448.50*.25= $112. 125

THIS IS NOT YOUR ANSWER!

don't forget that!

you will then subtract the sale price ($112.125) by the upcharged price ($448.50)

448.50-112.125= 336. 375

Round up then there is your answer!

= $336. 38

The magnitude Bode plot starts at 100 dB and decreases with a slope of -20 dB/decade, the phase plot starts at 0 degrees and decreases with a slope of -90 degrees.

To sketch the Bode plot and phase plot of the b H(f) = 100 / (1+j(f/1000)), we first need to express it in standard form:

H(jω) = 100 / (1 + j(ω/1000))

Hence, we have:

Magnitude:

|H(jω)| = 100 / √[1 + (ω/1000)²]

Phase:

∠H(jω) = -arctan(ω/1000)

Now, we can sketch the approximate asymptotic magnitude Bode plot and approximate phase plot as follows:

1. An advantage of offering more choices for something is that it gives customers a greater range of options to choose from, which can increase customer satisfaction and loyalty. Offering 50 flavors of ice cream instead of four can attract a wider range of customers with different preferences, leading to increased sales and revenue. Additionally, having more options can help differentiate the store from competitors, as customers may be more likely to choose a store that offers more variety.

2. An advantage of offering less for something is that it can simplify the decision-making process for customers. This can be particularly helpful for customers who are indecisive or overwhelmed by too many options. Offering only three flavors such as vanilla, chocolate, and swirl can make the decision-making process easier for customers, leading to a faster transaction and potentially increased customer satisfaction. Additionally, offering less can help the store to streamline its operations by reducing the number of ingredients and supplies needed, which can lead to cost savings.

The image is formed behind the mirror, and the image is upright.

Given data: Object height, h = 3.0 cm Image distance, v = ? Object distance, u = -20.0 cmFocal length, f = -60.0 cmUsing the lens formula, the image distance is given by;1/f = 1/v - 1/u

Putting the values in the above equation, we get;1/-60 = 1/v - 1/-20

Simplifying the above equation, we get;v = -40 cm

This negative sign indicates that the image is formed behind the mirror, as the object is placed in front of the mirror.

Hence, the image is virtual and erect. Using magnification formula;M = -v/uWe get;M = -(-40) / -20M = 2Hence, the height of the image is twice the height of the object.

The height of the image is given by;h' = M × hh' = 2 × 3h' = 6 cm Now, let's draw the ray diagram:

Thus, the position of the image is -40.0 cm and the height of the image is 6 cm.

Answer:

EF = 34

Step-by-step explanation:

EF + FG = EG , substitute values

17x + 3x + 7 = 18x + 11, that is

20x + 7 = 18x + 11 ( subtract 18x from both sides )

2x + 7 = 11 ( subtract 7 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Thus

EF = 17x = 17(2) = 34

Answer:

34

Step-by-step explanation:

g First, you need to find the value of x. To do this you need to add the lengths of EF and FG and set it equal to the total length of EG, then solve.

EF=17x, FG= 3x+7, EG = 18x+11

17x+3x+7=18x+11

Combine like terms.

20x+7=18x+11

-7          -18x

Isolate x.

2x = 4

Divide both sides by 2.

x=2

Now that we have the value for x, we need to plug it into the length of EF to find the numerical value.

17x = 17(2) = 34

In part (a) of the question, the expression is not provided, so it is not possible to determine which parts can be used to show that the value is always odd.

Since part (a) of the question does not provide the specific expression, it is not possible to identify which parts of the expression can be used to demonstrate that the value is always odd. The term "value" could refer to the result of the expression when evaluated for different inputs or variables.

To determine if the value of an expression is always odd, we need to examine its properties and terms. This could involve factors such as powers, coefficients, or the presence of odd numbers or variables.

Without knowing the specific expression or its components, it is not possible to identify the specific parts that would demonstrate the expression always yielding an odd value.

Therefore, without the provided expression from part (a), we cannot analyze or identify the parts that could prove the expression to always result in an odd value.

What is perimeter?

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length.

We know, In isosceles triangle the two sides are equal.

So, here in question in given that

The length of the base of an isosceles triangle is x.

The length of a leg is 2x − 5.

perimeter of the triangle is 20.

The formula of perimeter of isosceles triangle = 2a + b

a = sides of triangle

b = base

Here,

a = 2x - 5

b = x

perimeter = 20

Now, put these values in given formula and then solve for 'x'

2 ( 2x - 5) + x = 20

=> 4x - 10 + x = 20

=> 5x = 20 + 10

=> 5x = 30

=> x = 30/5

=> x = 6

Therefore, the value of x is 6

What is linear function?

A linear function is a mathematical function of the form:

f(x) = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line intersects the y-axis. The slope represents the rate of change of the function, or how much the function changes for a unit change in the independent variable x. The y-intercept represents the value of the dependent variable when the independent variable is equal to zero. Linear functions are characterized by a straight line when graphed on a coordinate plane.

To find the equation of the linear function, we can use the slope-intercept form of a line, which is:

y = mx + b

where m is the slope and b is the y-intercept. We know that the slope is 5, and the function passes through the point (-7, 5). We can use this information to solve for the y-intercept:

5 = 5(-7) + b

b = 40

Therefore, the equation of the linear function is:

y = 5x + 40

To find the value of the dependent variable when x = 2, we can substitute x = 2 into the equation and solve for y:

y = 5(2) + 40

y = 10 + 40

y = 50

Therefore, the value of the dependent variable when the independent variable is equal to 2 is 50.

Step-by-step explanation:

1/8= 5 ft

38/8 = 38*5 = 190 feet

The value of t at t = 0 is 0. The second derivative of the position vector r(t) at t = 0 is <18, 4, 0>. The dot product of the first derivative r'(t) and the second derivative r''(t) is 0.

To find t(0), we substitute t = 0 into the position vector r(t) and obtain the value of t at that point, which is 0. Thus, t(0) = 0.

To find r''(0), we differentiate the position vector r(t) twice with respect to t. The derivative of r(t) with respect to t gives us the velocity vector r'(t), and the derivative of r'(t) gives us the acceleration vector r''(t). Differentiating each component of r(t) individually, we get:

r'(t) = <6\(e^3^t\), -4\(e^3^t\), 4\(e^3^t\) + 4t\(e^3^t\)>

r''(t) = <18\(e^3^t\), \(e^3^t\), 12\(e^3^t\) + 4\(e^3^t\) + 4t^2\(e^3^t\)>

Substituting t = 0 into r''(t), we get r''(0) = <18, 4, 0>.

To find r'(t) · r''(t), we take the dot product of r'(t) and r''(t). The dot product of two vectors is calculated by multiplying their corresponding components and summing the results. Evaluating the dot product, we have:

r'(t) · r''(t) = (6\(e^3^t\) * 18\(e^3^t\)) + (-4\(e^3^t\) * 4\(e^3^t\)) + (4\(e^3^t\) + 4t\(e^3^t\)) * (12\(e^3^t\) + 4\(e^3^t\) + 4t²\(e^3^t\))

Simplifying this expression, we obtain r'(t) · r''(t) = 0.

Answer:

The additional cost is $0.12 for each additional mile the van is driven ⇒ D

Step-by-step explanation:

The form of the linear function is

f(x) = m x + b, where

m is the rate

b is the initial value

In our question

The function C(d) = 0.12 d + 25 represents the cost C in dollars of the rental van uses for d miles

→ Compare it with the form of the linear function above

∴ m = 0.12

∴ b = 25

∵ The cost C depends on the number of miles d

∴ $0.12 is the cost per mile ⇒ additional cost for each additional mile

∴ $25 is the initial cost ⇒ initial cost of the moving the van

The interpretation of the slope for this function is:

The additional cost is $0.12 for each additional mile the van is driven

Answer:
