First let’s derive the equation. The situation represents a linear equation since there is a constant proportional relationship, and y (total fee) changes based on x (miles traveled). So, we can use the form: y=mx+b.

To do so, we must find the slope (m), which represents the linear rate of change, so let’s choose two ordered pairs and plug them into the slope formula.

Ordered pairs (x, y)——>(miles traveled, total fee)

(2, 17) and (5, 21.50)

Slope formula:

m=(y₂ - y₁)/(x₂ - x₁)

Plug in the ordered pairs from above:

m=(21.5-17)/(5-2)

Simplify:

m=4.5/3

m=1.5

So, the rate is $1.5 per mile. To determine the y-intercept (if there is one), we used a point we already have and input x into the equation and determine how y is formed.

We currently have the equation: y=1.5x+b, where b=y-intercept and is unknown currently.

Let’s plug in the first ordered pair: (2, 17). We will then solve for b.

(17)=1.5(2)+b

Simplify:

17=3+b

Solve for b (y-intercept):

Subtract 3 from both sides:

17-3=b

14=b; b=14

So, we now have a y-intercept of 14. Let’s complete the equation now that we have all the information:

y=1.5x+14

Let’s input two ordered pairs into the equation again to assure we’re correct. For simplicity, we’ll use (2, 17) and (5, 21.50):

(17)=1.5(2)+14

Simplify:

17=3+14

17=17

Now, the second ordered pair:

(21.5)=1.5(5)+14

Simplify:

21.5=7.5+14

21.5=21.5

So, we are correct with the equation.


This means that answer is: the first option - “When the cab travels 0 miles, the fee is $14.00.”

How do logarithmic functions model real-world problems and their solutions? Give a specific example and explain.

Answers

The process of logarithmic functions in real-worlds problems is given below.

And an example of an application of logarithmic function is given.

What is Logarithmic?

The inverse of exponentiation is the logarithm. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b.

We know,

logarithmic function and exponential function are inverse of each other.

So, whenever we solve the exponential function,

we use the help of logarithmic functions.

To compute the number with bigger exponents,

we use the logarithms.

Because it reduces the size of the numbers.

Let the bacteria is growing exponentially,

b = 2ⁿ.

We know that the bacteria grows every hour.

We want to find time.

Here, we will use the inverse function to the exponential function.

How long will it take them to get 1000 bacteria?

1000 = 2ⁿ

Taking log on both sides,

log(1000) = n log2

n = log(1000)/log(2)

n = 9.96

n ≈ 10 hours.

Therefore, an application of logarithmic function is given above.

Answers

The probabilities of the number of people told that they have hypertension, using the binomial distribution, are given as follows:

a) Zero: 0.2536 = 25.36%.

b) More than 1: 0.3461 = 34.61%.

c) Between one and three: 0.7331 = 73.31%.

d) Two or fewer: 0.9068 = 90.68%.

e) Five: 0.0008 = 0.08%.

What is the binomial distribution formula?

The mass probability formula, giving the probability of x successes, is of:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are given by:

n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.

The values of these parameters for this problem are given as follows:

p = 0.24, n = 5.

Hence the probability for each outcome in the distribution is given as follows:

P(X = 0) = (1 - 0.24)^5 = 0.2536.P(X = 1) = 5 x 0.24 x (1 - 0.24)^4 = 0.4003.P(X = 2) = 10 x 0.24² x (1 - 0.24)³ = 0.2529.P(X = 3) = 10 x 0.24³ x (1 - 0.24)² = 0.0799.P(X = 4) = 5 x 0.24^4 x (1 - 0.24) = 0.0126.P(X = 5) = (0.24)^5 = 0.0008.

Hence the missing probabilities are given as follows:

b) More than 1: 1 - (0.2536 + 0.4003) = 0.3461 = 34.61%.

c) Between one and three: 0.4003 + 0.2529 + 0.0799 = 0.7331 = 73.31%.

d) Two or fewer: 0.2536 + 0.4003 + 0.2529 = 0.9068 = 90.68%.

table x seconds after the fan is turned on. What is the height of the mark
above the table when it is closest to the table?

Answers

Answer:  5 cm

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

Explanation:

Recall that the range for cosine is from -1 to 1, including both endpoints. The smallest cosine value is what we're after, since we want the height to be as small as possible (to allow the blade be closest to the table).

Effectively, this means we replace the cos(x) with -1 so that it's as small as possible. Then we compute to get:

20*cos(x)+25

20*(-1) + 25

-20 + 25

5

The height of the fan tip is 5 cm when it is the closest to the table.

Side note: On the flip side, the furthest away the fan tip can get is 20*(1) + 25 = 45 cm. Therefore, the range of y values is [tex]5 \le y \le 45[/tex]

An item on sale costs 80% of the original price. The original price was 33%

Answers

The sale price of the item is given by the equation A = $ 26.40

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the sale price of the item be represented as A

Now , the equation will be

The original price of the item = $ 33

An item on sale costs 80% of the original price

So , the sale price of the item A = 80 % x original price of the item

Substituting the values in the equation , we get

The sale price of the item A = ( 80 / 100 ) x 33

The sale price of the item A = 0.80 x 33

The sale price of the item A = $ 26.40

Therefore , the value of A is $ 26.40

Hence , the sale price is $ 26.40

 The x2 and y2 terms share the same scaling factor, despite the fact that this equation contains a bunch of other garbage (which is 1). This ought to be screaming "circle" to you.

2. x^2 - 6y = 0

 The x term is squared, but the y term is not, which is an important distinction to make. A parabola is clearly indicated by this fact.

3. 4x^2 + 9y^2 = 1

This is the result of adding an x-squared and a y-squared phrase. That kind of sounds circular, but the results are scaled by those two coefficients. Additionally, they vary. So, a closed curve that resembles a circle but is slightly stretched out is what we're searching for. An ellipsis appears there.

A function expression

The function expression is given as

V(x) = (x)(x + 1)(x – 2)

Where if x is in centimeters and V(x) is in cubic centimeters

The new function for the volume of the refrigerator is stated to be in cubic millimeters

Using the above as a guide, we have the following:

1 cubic centimeters = 1000 cubic millimeters

So, we have

V(x) = (x)(x + 1)(x – 2)

1 cubic centimeters = 1000 cubic millimeters

Cross multiply

V(x) * 1000 = 1* (x)(x + 1)(x – 2)

Divide both sides by 1000

V(x) = (x)(x + 1)(x – 2)/1000

Since three people have the same name, everyone else gets less probability of getting called so the answer would be D.

Option D

Step-by-step explanation:

Total Students in a class: 24

Total Madisons in the class: 3

Denominator is always the total number of something so; [tex]\frac{3}{24}[/tex]

3/24 = 0.125

In accordance with this rule, it may safely be assumed that the forefathers of Boston had built the first prison-house, somewhere in the vicinity of Cornhill, almost as seasonably as they marked out the first burial-ground, on Isaac Johnsons lot, and round about his grave, which subsequently became the nucleus of all the congregated sepulchres in the old church-yard of Kings Chapel. Certain it is, that, some fifteen or twenty years after the settlement of the town, the wooden jail was already marked with weather-stains and other indications of age, which gave a yet darker aspect to its beetle-browed and gloomy front. The rust on the ponderous iron-work of its oaken door looked more antique than anything else in the New World. Like all that pertains to crime, it seemed never to have known a youthful era. Before this ugly edifice, and between it and the wheel-track of the street, was a grass-plot, much overgrown with burdock, pig-weed, apple-peru, and such unsightly vegetation, which evidently found something congenial in the soil that had so early borne the black flower of civilized society, a prison. But, on one side of the portal, and rooted almost at the threshold, was a wild rose-bush, covered, in this month of June, with its delicate gems, which might be imagined to offer their fragrance and fragile beauty to the prisoner as he went in, and to the condemned criminal as he came forth to his doom, in token that the deep heart of Nature could pity and be kind to him.This rose-bush, by a strange chance, has been kept alive in history; but whether it had merely survived out of the stern old wilderness, so long after the fall of the gigantic pines and oaks that originally overshadowed it,or whether, as there is fair authority for believing, it had sprung up under the footsteps of the sainted Ann Hutchinson, as she entered the prison-door,we shall not take upon us to determine. Finding it so directly on the threshold of our narrative, which is now about to issue from that inauspicious portal, we could hardly do otherwise than pluck one of its flowers, and present it to the reader.
