Graph Each Function And Identify Its Domain, Range, Intercepts, Asymptotes, And Holes. Thank You! :)

Answers

Answer 1

Answer:

Domain: real numbers except {-4, -3, 0}Range: real numbers except {2}Intercepts: (-1, 0); no y-intercept (see Holes)Asymptotes: horizontal, y = 2; vertical, x = -3Holes: (-4, 6), (0, 2/3)

Step-by-step explanation:

You want the domain, range, intercepts, asymptotes, and holes of the rational function f(x) = (2x³ +10x² +8x)/(x³ +7x² +12).

Simplified

The given function can be simplified by cancelling common factors from numerator and denominator. These cancelled factors show where the holes are in the graph.

  [tex]f(x)=\dfrac{2x^3+10x^2+8x}{x^3+7x^2+12}=\dfrac{2x(x+4)(x+1)}{(x(x+4)(x+3)}=2\left(\dfrac{x+1}{x+3}\right)\quad x\notin\{-4,-3,0\}[/tex]

Domain

The function is defined for all real numbers except those where the denominator is zero: {-4, -3, 0}.

Range

The function can produce every output value except the value of the horizontal asymptote: y = 2. The range is all real numbers except 2.

Intercepts

The x-intercept is found where the numerator of the simplified function is zero: x = -1

The y-intercept is the function value at x=0. The function is undefined there, so the y-intercept does not exist. (The limit as x approaches zero is y = 2/3.)

Asymptotes

The function has a horizontal asymptote at the y-value corresponding to the ratio of the highest-degree terms of the numerator and denominator: y = 2.

The vertical asymptote is at the uncanceled denominator zero, x = -3.

Holes

The holes are where a numerator and denominator factor cancel. The y-value at the hole is the limit of the function value as x approaches the hole location. This is the value of the simplified function.

The holes are (-4, 6) and (0, 2/3).

a frog starts at location a and wants to get to location b that is 500 meters away. starting at a, it sits at a given spot on the path from a to b for a time that is exponen- tially distributed with parameter 1 (minute). after that, it jumps 1 meter towards b, sits in the new spot for an exponentially distributed time, etc. all the times are independent. what is the probability (approximately) that it will get to b within 7 hours?

Answers

The probability that it will get to b within 7 hours is approximately 0.014.

Probability:

In math, the favorable way of happening the event is known as probability.

Given,

A frog starts at location a and wants to get to location b that is 500 meters away. starting at a, it sits at a given spot on the path from a to b for a time that is exponentially distributed with parameter 1 (minute). after that, it jumps 1 meter towards b, sits in the new spot for an exponentially distributed time, etc. all the times are independent.

Here we need to find the the probability (approximately) that it will get to b within 7 hours.

While we looking at the given question we have identified that,

starting point = a

ending point = b ( 500 meters)

Time take for one jump = 1 minute

Distance covered in one jump = 1 meter.

Here they also said that the time is independent but the distance remains constant.

So, the probability that it will get to b within 7 hours is calculated as,

=> 7/500

=> 0.014

a 28 year old man plays 165 for a one year life insurance policy with coverage of 140000 if the probability that he will live through the year is 0.9994 what is his expected value for the insurance polixy

Answers

The insurance policy's anticipated value is -$81 for the one year life insurance policy.

Explain the term insurance policy?Term insurance is a form of life insurance policy which offers protection for a certain "term" of years, or a set amount of time.A deceased person will be paid if the insured passes away while the term insurance is still in effect and the insurance is active.

Consider the various factors and the man's potential benifits.

-$165 because he already paid that sum.

The beneficiary could earn as a potential profit.

140000-165 = $139835

The probability of surviving is 0.9994.

The likelihood of not living is 0.0006.

The expected value is given by;

E(v) = (-165)(0.9994) + (139835)(0.0006)

E(v) = -164.901 + 83.901

E(v) = -81.

Thus, the insurance policy's anticipated value is -$81.

Enter an equation of the line (in slope-intercept form) that passes through the point (20, −7) and is perpendicular to the line y = −5x + 9. Express any numeric values as integers or simplified fractions.

Answers

Answer:

  y = 1/5x -11

Step-by-step explanation:

You want the slope-intercept equation of the line perpendicular to y=-5x+9 that goes through the point (20, -7).

Slope-intercept form

The slope-intercept form of the equation for a line is ...

  y = mx +b . . . . . . . . where m is the slope and b is the y-intercept

This can be solved to find the y-intercept from a point on the line:

  b = y -mx

Comparing this form to the given equation, you see the given line has a slope of m = -5.

Perpendicular line

The perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line:

  slope = -1/(-5) = 1/5

Y-intercept

The y-intercept of the desired line can be found using the equation for b above. The y-intercept of the line with slope 1/5 through point (x, y) = (20, -7) is ...

  b = y -mx = (-7) -1/5(20) = -7 -4

  b = -11

Now, we have the slope and intercept of the desired line, so we can write its equation:

  y = 1/5x -11

the gas mileage for a certain model of car is known to have a standard deviation of 4 mi/gallon. a simple random sample of 81 cars of this model is chosen and found to have a mean gas mileage of 27.5 mi/gallon. construct a 95% confidence interval for the mean gas mileage for this car model.

Answers

The 95% confidence interval for the mean gas mileage for this car model is (26.26, 28.74) mi/gallon.

The confidence interval for a statistical data is written as-

(x+ zr/√n, x- zr/√n)

Here, we are given that-

Mean ⇒ x = 27.5 mi/gallon.

Standard deviation ⇒ r = 4 mi/gallon

Number of samples ⇒ n = 49

and Confidence interval = 95%

z-score at 95% confidence level = 2.17

Substituting the values we have;

= [27.5 - 2.17(4.0) /(√49),  27.5 + 2.17(4.0) /(√49)]

= (27.5 - 8.68 / 7,  27.5 + 8.68 / 7)

= (27.5 - 1.24,  27.5 + 1.24)

= ( 26.26, 28.74)

What is a probability simple definition?

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to express probabilities.

What is the probability formula?

P(A) = n(A)/n (S)

The probability of an event "A" is P(A). The number of successful outcomes is n(A). The total number of events in the sample space is denoted by n(S).

1)  From the set we can select 4*3*2*1=24 permutations.

2) There are six permutations that begin with 1, three that begin with 2, three that begin with 3, and no permutations that begin with 4 when 1 comes before 4. So, P1 ={ 6+3+3+0}/{24} = 1/2

3) No permutations begin with 1, three permutations begin with 2, three permutations begin with 3, and six permutations begin with 4, where 4 comes before 1. P2=1/2 

4) There are no permutations that begin with 1, no permutations that begin with 2, no permutations that begin with 2, no permutations that begin with 3, and six permutations that begin with 4, where 4 comes before both 1 and 2. Therefore, P 3 = 1/3

​5) No permutations begin with 1, no permutations begin with 2, no permutations begin with 3, and there are six permutations that begin with 4, where 4 comes before 1, 2, and 3. So, P4= 1/4

​6) There are no combinations that begin with 1, three combinations that begin with 2, no combinations that begin with 3, and three combinations that begin with 4, where 4 comes before 3 and 2 comes before 1. So, P5= 1/4

the length of a rectanglar photograph is 7 inches more than the width. if the are is 78 inches squared, what are the dimensions of the photograph

Answers

The dimensions of the photograph are found as 13 in and 6 in.

Explain the term rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides.

Let length = x.

So, width = x - 7

Area = length x width

A = x (x -7)

and A = 78 inches squared.

Thus,

78 = x (x -7)

On solving.

x² - 7x - 78 = 0

Find the factors of the quadratic equation,

x² - 7x - 78 = 0

(x - 13)(x + 6) = 0

Thus,

x = 13 and x = -6 but (x > 0)

Thus, when x = 13 in,

Width = x + 7

Width = 13 - 7

Width = 6 in

What is meant by an angle?

In Euclidean geometry, an angle is the figure formed by two rays, known as the sides of the angle, that have a common termination, known as the vertex of the angle. These are referred to as dihedral angles. An angle can also be defined by two intersecting curves, which is the angle of the rays lying tangent to the respective curves at their point of intersection.

Given, ∠b =  40  

∠d = 70

∠1 = ∠ a

∠2 = ∠c

∠1 = ∠2

So, ∠1 =∠2 = ∠a = ∠c

70 + 40 + ∠a + ∠2 = 180

110 + 2∠a = 180            

2∠a = 180 - 110

∠a = 70/2
