If t represents the amount of time Neda has spent typing the second letter, which equation states the rule used to determine the number of words, W, Neda has typed today?

Answers

Answer:

W = t + 200

Step-by-step explanation:

Number of words typed in the first letter = 200

The relationship between the total words typed, W and the number of seconds, t spent on the second letter :

W = number of words typed in first letter + t

W = 200 + t

Choosing any pair of values from the table :

W = 245 ; t = 45

W = 200 + 45

W = 245

Therefore, the number of words, W typed today can be represented as

W = 200 + t

Answers

I think is B.............

The given histogram is unimodal skewed.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

This histogram is unimodal skewed.

There are two parts to this answer. The first part has to do with the number of modes.

This would be the item that is occurring the most frequently. In this case the mode is only 4.

It is occurring more than any other.

The second part of this has to do with the distribution of the data as it is displayed on the histogram.

There are 4 pieces of data that are only occurimg one time on the right of the histogram. We call this skewing the data.

When both sides looks almost the same we say it is symmetric.

Hence, the given histogram is unimodal skewed.

PLEASE HELP

The filament of a car headlight is a thin wire that glows when electricity passes through it. Parabolic reflectors with a filament at the focus send light out in a straight beam. The cross section of a 2 inch deep headlight reflector has the equation y2=6x.

A. Draw a sketch of this situation. Include the location of the focus in your drawing.

B. How wide is the beam of light projected from the headlight's reflector? Show all work and give your answer as a decimal rounded to hundredths place.

Answers

Answer:

A. Please find attached the drawing of the reflector showing the location of the focus created with Microsoft Excel

B. The width of the beam of light projected from the headlight's reflector is approximately 6.93 inches

Step-by-step explanation:

The given equation representing the cross section of the headlight reflector is y² = 6·x

The shape of the reflector = Parabolic

The general equation of a parabola is (y - k)² = 4·p·(x - h)

The focus of the parabola, Focus = (h + p, k)

By comparison to the general equation of a parabola, from the equation of the reflector, we have;

k = 0, h = 0, 4·p = 6

∴ p = 6/4 = 3/2 = 1.5

∴ The focus of the parabola = (1.5, 0)

A. Please find attached the graph of the equation of the cross-section of the reflector, showing the filament at the focus, created with Microsoft Excel

B. The depth of the reflector is x = 2 inches

A vertical or horizontal parabola has two x-values for a given y-value or two y-values for a given x-value respectively

For the given horizontal parabola, the width of a parabola at a point is the difference between the two y-values at the point

At x = 2, we have;

y² = 6 × x = 6 × 2 = 12

∴ y = ±√(12)

The two y-values at x = 2 are y₁ = √(12) and y₂ = -√(12)

The width of the parabola, w = y₁ - y₂

The width of the parabola at x = 2, w = √(12) - (-√(12))

∴ w = √(12) +√(12) = 4·√3

The width of the parabola at x = 2, w = 4·√3 inches

The width of the parabola at x = 2 = The width of the beam of light projected from the headlight's reflector = 4·√3 inches

By giving the answer as a decimal and rounded to the hundredths place, we have;

The width of the beam of light projected from the headlight's reflector ≈ 6.93 inches.

1. a. The image's dilated side lengths on each side:

AB = CD = 45cm.

BD = AC = 24cm.

2. a. Equal ratios exist between the lengths of matching sides. The ratio is the same as the dilation's scale factor.

b. The image is a dilation of the original image.

c. The scale factor = 4.

3. a. The image is a dilation of the original image.

b. The scale factor = 2.

What do you mean by scale factor?

A scale factor, often referred to as a conversion factor, is a numerical value that is used to alter a figure's size without altering its shape. The scale factor can be calculated if both the dimensions of the original and the dilated (increased or lowered) figure are known. The basic formula for calculating a figure's scale factor is given as,

Scale factor is equal to the division between the dimensions of the new and old shapes.

In the first figure, the sides are given as:

AB = 15cm

BD = 8cm

Scale factor = 3

Now, using the scale factor formula:

Scale factor = New dimensions/Old dimensions

⇒ 3 = New dimension/15

⇒ New dimension of AB = 45cm.

Similarly, new dimension of BD = 24cm.

In the second figure, as the lengths of corresponding sides have equal ratios. Both the figures are similar. The image is the dilation of the original figure as the lengths of corresponding sides have equal ratios. The ratio is the same as the dilation's scale factor. So, the scaler factor here is 4.

Now in the last figure we can see that the coordinates of A', B', C' and D' are exactly half of that of the coordinates of A, B, C and D.

The ratio of the coordinates is 2:1.

Therefore, the scale factor = 2.
