Answers

Answer 1

Statement A,B is true rest all statement are false about the given function.

Given the function: [tex]2x^3+8[/tex]

Statement A:

The domain of a function is the set of all possible input values (x-values) for which the function produces a valid output (y-value).

For the function 2x^3 + 8, the domain is all real numbers, which is represented as (-infinity, +infinity).

It is because the expression inside the function, 2x^3, is defined for all real numbers.

so above statement is true.

Statement B:

statement A and B are same so it's also true.

Statement C:

The range of a function is the set of all possible output values (y-values) that the function can produce.

For the function 2x^3 + 8, the range is also all real numbers (-infinity, +infinity)

It is because the function is a polynomial of odd degree (3) and it does not have any restriction on the output value. Since the function does not have any restriction, it can take any real number as an output value and thus the range is all real numbers.

so this statement is false.

Statement D:

The y-intercept of the function 2x^3 + 8 is 8. It is the point at which the graph of the function crosses the y-axis, which occurs when x = 0. So when x = 0, y = 2(0)^3 + 8 = 8.

so this statement if false.

Statement E:

A function has a center of symmetry if it is unchanged (i.e. is symmetric) when reflected across a line or point. The line or point across which the function is symmetric is called the axis of symmetry or center of symmetry.

The function 2x^3 + 8 does not have a center of symmetry. It is because the function is a polynomial of odd degree and it does not have any symmetry. The polynomials of odd degree are not symmetric about any point or line.

So this statement is also false.

Remembering the ratio of 1: 3: 2 and understanding that the smallest side length is always opposite the shortest angle (30°) and the longest side length is always opposing the greatest angle (90°) can help you recall the 30-60-90 triangle principles.

According to the 30-60-90 triangle theorem, the hypotenuse is twice as long as the shorter leg. Additionally, the sides of this particular triangle have a ratio of 1:2: [tex]\sqrt{3}[/tex].

A 30-60-90 triangle can have three sides, and if you only know one, you can use shortcuts to discover the other two. The three scenarios you encounter when performing these computations are as follows:

You are aware of the short leg (the side across from the 30-degree angle). To find the hypotenuse, multiply the length by two. The long leg can be calculated by multiplying the short side by the square root of 3.You are aware of the hypotenuse. To get the short side, divide the hypotenuse by two. To determine the long leg, multiply this response by the square root of 3.You are aware of the long leg (the side across from the 60-degree angle).

A trainer at a gym earns $2,456.75 every month. She earns an extra $4.75 every time she sells
a gym membership. Last month, the trainer sold 32 gym memberships. What is the total amount
of money the trainer earned last month?

Answers

Answer: We know that the trainer earns $2,456.75 every month, and she earns an extra $4.75 every time she sells a gym membership.

And last month she sold 32 gym memberships

We can calculate the total amount of money the trainer earned from selling gym memberships by multiplying the number of memberships sold by the amount earned per membership:

32 memberships * $4.75 per membership = $152.00

To find the total amount of money the trainer earned last month, we can add the amount earned from selling gym memberships to the amount earned from her salary:

$2,456.75 + $152.00 = $2,608.75

So, the total amount of money the trainer earned last month is $2,608.75

How to determine the initial value of the function?

In order to determine the initial value of the function, we would have to find the slope from line graph and then write the required equation based on the data points contained in the table by using the slope-intercept form.

Mathematically, the slope-intercept form of a line is modeled by this mathematical equation:

y = mx + c

Where:

m represents the slope.x and y are the data points.c represents the y-intercept or initial value.

Next, we would determine the slope of the data points as follows;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (5 - 7)/(0 + 1)

Slope, m = -2/1

Slope, m = -2.

At point (0, 5), an equation of this line can be calculated in slope-intercept form as follows:

A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the components 3x + 5 and 14 in the equation 3x + 5 = 14 are separated by an equal sign. The relationship between two sentences on either side of a letter is expressed mathematically. There is frequently only one variable, which doubles as the symbol. say that 2x - 4 Equals 2.

Here,

y = mx + b

(50,13.98)(78,17.06)

slope = (17.06 - 13.98) / (78 - 50) = 3.08 / 28 = 0.11

slope(m) = 0.11

use either of ur points...(50,13.98)...x = 50 and y = 13.98

now sub into the formula and find b, the y int

13.98 = 0.11(50) + b

13.98 = 5.5 + b

13.98 - 5.5 = b

8.48 = b

[tex]\begin{aligned}\implies w(0)&=29+0.0674(0)\\&=29+0\\&=29\end{aligned}[/tex]

Therefore, the constant of the equation (29) is the estimated weight of the beaver, in pounds, when t = 0.

As t = 0 is June 1:

29 is the estimated weight, in pounds, of the beaver on June 1.

a rock is thrown off a bridge 40 feet above a river at an initial velocity of 96 feet per second. The height h, in feet, of the rock t seconds after it was thrown can be modeled by the function h(t)=-16t^2 +96t+40. Find the height of rock 4 seconds after it was thrown.

Answers

The height of rock 4 seconds after it was thrown is 168 ft.

What is speed?

Speed is measured as distance moved over time.

Speed = Distance/ Time.

Here, given that,

we have

a rock is thrown off a bridge 40 feet above a river at an initial velocity of 96 feet per second.

The height h, in feet, of the rock

t seconds after it was thrown can be modeled by the function

h(t)=-16t^2 +96t+40.

where

h -----> is the height in feet of the rock

t -----> the time in seconds

For , t=4, we get,

substitute the value of t in the function and find the value of h

h(4)=-16×4^2 +96×4+40.

So, h= 168

Hence, the height of rock 4 seconds after it was thrown is 168 ft.

The average rate of change is the ratio of the difference between the y coordinates of two points to the x coordinate of the same point.

It can be found by using two points on the graph and substitute into the formula: (y₀ - y₁) / (x₀ - x₁)

The square brackets [] is used to mean the end points as shown is inclusive

What is average rate of change in quadratic equation?

A quadratic equation is a polynomial of degree two

The average rate of change here is not constant and is usually  specified by the two points to which it is measured

For instance using points (-3, 0) and (0, -1) we have

=  (y₀ - y₁) / (x₀ - x₁)

=  (-1 - 0) / (0 - (-3))

= -1/3

Read the passage. There are several questions about this passage.whether formed by water run-off, deer, or wild turkey, every path seemed tobe a desire path.2But when we were some hundred feet below the ridge line, the signalpicked up, and its steady, loud chirping took us to the old black locust tree,seventy or maybe seventy-five feet tall, with cracks and fissures in its deeplyfurrowed bark that made it an accommodating roost. A pamphlet from the USFish and Wildlife Division of the Department of Environmental Conservationdescribes the Indiana bat as having fur that is "dull grayish chestnut ratherthan bronze, with the basal portion of the hairs of the back dull lead colored.This bat's underparts are pinkish to cinnamon, and its hind feet small anddelicate." I saw nothing like this, but when we listened very carefully, we couldhear their hum of gentle chattering. Bats use sound to situate themselves;their capacity for echolocation is what guldes them, what elucidates theirsense of space and substance, what locates their prey. But the sound, a seriesof tiny clicks ten or twenty, forty or even two hundred times a second, is at afrequency beyond most human hearing; it is exactly that high frequency withits short wavelengths that produces the detailed echoes the bats rely on tolearn the shape of their universe. We live in an acoustical empire we will neverknow, our threshold of hearing situated somewhere between the low,Infrasonic rumbling of elephants and the high-pitched ultrasonic rasping oftenrec shrews that rub their quills together to communicate. I knew that thesubtle whispering I could make out was but a fraction of the sound sensationthe bats were creating and, listening to the soft murmuring, felt I was standingat the gate to a remote kingdom of sound that could only be imagined.In paragraph 2, how are elephants and tenrec shrewsrelated to the human "threshold of hearing"?1.

Read the following article on Gertrude Elion. Then, read the summary that follows. You will notice that the summary is incorrectly written. In this lesson, you learned six rules for writing an effective summary. Using this information, make three specific suggestions that would improve this ineffective summary.Important note: Do NOT write a summary. You will write three suggestions for improving this summary. Your suggestions must be based on the six rules of effective summaries that you learned in the lesson.Complete article from Encyclopedia BritannicaU.S. pharmacologist (one who studies drug interactions) Gertrude B. Elion received the Nobel prize for medicine in 1988 along with George H. Hitchings and Sir James W. Black. The three were awarded the prize for their development of drugs used to treat several major diseases.Gertrude Belle Elion was born on Jan. 23, 1918, in New York City. She graduated from Hunter College in New York City with a degree in biochemistry in 1937. Unable to obtain a graduate research position because she was a woman, she took a series of jobs, including lab assistant, chemistry and physics teacher in New York City high schools, and research chemist. During this time she also took classes at New York University, where she earned a master's degree in 1941. Because she could not devote herself to full-time studies, Elion never received a doctorate.In 1944 Elion joined the Burroughs Wellcome Laboratories (now part of GlaxoSmithKline (a company that makes prescription medicines)). There she was first the assistant and then the colleague of Hitchings, with whom she worked for the next four decades. Elion and Hitchings developed an array (variety) of new drugs that were effective against leukemia, autoimmune disorders, urinary-tract infections, gout, malaria, and viral herpes. Their success was due primarily to their innovative (characterized by new or unique) research methods. Rather than using the trial-and-error approach used by previous pharmacologists, Elion and Hitchings examined the difference between the biochemistry of normal human cells and that of cancer cells, bacteria, viruses, and other pathogens (disease-causing agents). They used this information to create drugs that could target a particular pathogen without harming the human host's normal cells. Their methods enabled them to eliminate much of the guesswork and wasted effort typical in previous drug research.Although Elion officially retired in 1983, she helped oversee the development of azidothymidine (AZT), the first drug used in the treatment of AIDS. In 1991 she was awarded a National Medal of Science and was inducted into the National Women's Hall of Fame. She died on Feb. 21, 1999, in Chapel Hill, N.C.Student J. Doe's SummaryGertrude Elion was born in 1918 in New York City. She went to school for many years and eventually won the Nobel prize. She was unable to obtain a graduate research position because she was a woman. She took a series of jobs, including lab assistant, chemistry and physics teacher in New York City high schools, and research chemist. She was a scientist who helped discover many important drugs that saved lives. Elion also discovered new ways to test drugs. She died in 1999, 16 years after she retired from Burroughs Wellcome Laboratories. I think she was a terrific scientist. (10 points) 1/3x-2 9x-4/3x-13x-10 - 7/x-1 Read the passage from the opinion of the court in Dred Scott v. Sandford, written by Justice Taney.The question before us is, whether the class of persons described in the plea in abatement compose a portion of this people, and are constituent members of this sovereignty? We think they are not, and that they are not included, and were not intended to be included, under the word "citizens" in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States. On the contrary, they were at that time considered as a subordinate and inferior class of beings, who had been subjugated by the dominant race, and, whether emancipated or not, yet remained subject to their authority, and had no rights or privileges but such as those who held the power and the Government might choose to grant them.Which statement best serves as a counterclaim to the claim in this passage?Taney fails to provide any actual evidence for his statements that Black people were universally considered inferior.Taney cannot use states rights to claim that the plaintiff is not a citizen, because citizenship is federal. Taneys argument that emancipated people were still controlled by White people is false because they were free.Taneys argument that Blacks were not citizens is false because their ancestors were forced to come here.
