Answers

Answer 1
the first one would be -3.5 and the second will be -6.5
Answer 2

The value of x is -3.5 and y is 6.5 for the given equations.

What is an equation?

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The equations will be solved as:-

−3x + y = 4

−9x + 5y = −1

Multiply the first equation by 3 and subtract the second equation.

−15x + 5y = 20

9x - 5y = -1

--------------------

-6x =   21

  x = -3.5

Put x = -3.5 into first equation.

(-3x3.5) + y = 4

y = 6.5

Hence, the values are -3.5 and 6.5.

What is the wavelength of an earthquake wave if it has a speed of 7 km/s and a frequency of 3 Hz?

Answers

500 meters
wavelength = speed / frequency (5000m/s /10Hz)

Answer: Our wavelength will be 2333.3 m.

Step-by-step explanation:

Since we have given that

Wave speed = 7 km/ s

Frequency = 3 Hz

We need to find the wavelength of an earthquake wave:

As we know that :

[tex]Frequency=\dfrac{Wave\ speed}{wavelength}[/tex]

First we convert km/sec to m/sec.

So, 7 km/sec= 7000 m/sec

so, our wavelength becomes

[tex]\dfrac{Wave\ speed}{frequency}\\\\\\=\dfrac{7000\ m/sec}{3\ Hz}\\\\\\=2333.33\ m[/tex]

So, our wavelength will be 2333.3 m.

How do I answer this equation? -3x+y=12. I'm supposed to find the function for it bt I don't know how. Can you guys help me out please

Answers

Typically when being asked for a function, they want it written in slope intercept form. To find that, you need to solve for y.

You can do this by adding 3x to both sides which would result in y = 3x + 12.

Also, math teachers typically want functions expressed in terms of f(x) instead of y. So, you can replace your y with that to get the final answer of f(x) = 3x + 12.

Answer:

[tex]y=3x+12[/tex]

Step-by-step explanation:

We have been given an equation in standard form [tex]-3x+y=12[/tex]. We are asked to write our given equation as a function.

We know that the function represents a relationship between input and output, where each input gives exactly single output.  

To write our given equation as a function we need to convert our given equation into slope-intercept form of equation because in slope-intercept form, there is exactly one y output for each input of x.

[tex]y=mx+b[/tex], where,

m = Slope,

b = The y-intercept.

To convert our given equation into slope-intercept form, we need to get y on left side of our equation.

[tex]-3x+3x+y=3x+12[/tex]

[tex]y=3x+12[/tex]

Now our equation is in form of a function, where each value of x gives exactly one y value.

Answers

A 5th degree polynomial means that when simplified, the variable is to the 5th power. A trinomial is when there are three different components.

Therefore, your answer is A because there is an x to the 5th power, and three different components (3, -7x^5, and x^2)

Answer: The answer you are looking for is option A which would be 3  - 7x^5 +x^2

Step-by-step explanation: It is a 5th degree trinomial because, there are three terms in this equation being 3, 7x^5, and x^2; this makes it a trinomial becuase there are three terms. What makes this a 5th degree is the fact that the highest exponet is 5.

What are the equations of the horizontal asymptotes of y = (4e^x+7)/(e^x-1) in the xy plane?

Answers

In order to find a horizontal asymptote of a function f(x), you need to calculate
[tex] \lim_{x \to \infty} f(x) [/tex] = n
where n is a finite number.

in your case you have to caculate separately the two limits:

a) [tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 } [/tex] = [tex] \frac{\infty}{\infty} [/tex]

To solve this, you need to regroup eˣ both on the numerator and on the denominator:
[tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = [tex]\lim_{x \to +\infty} \frac{4 e^{x} (1 + \frac{7}{ e^{x} } ) }{ e^{x} ( 1 - \frac{1}{ e^{x} } ) }[/tex]

At this point the two eˣ cancel out and the parenthesis tend to 1, therefore
[tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = 4
Your first horizontal asymptote is y = 4.

b) Let's calcuate now:

[tex]\lim_{x \to -\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = [tex] \lim_{x \to -\infty} \frac{0 + 7}{0 - 1} [/tex] = -7
Therefore your second horizontal asymptote is y = -7

Your answer is, hence, y = 4 and y = -7 are horizontal asymptotes of the given function.


Final answer:

The horizontal asymptotes of the function y = (4e^x+7)/(e^x-1) are y = 4 and y = -7, occurring as x approaches positive and negative infinity respectively.

Explanation:

The equations of the horizontal asymptotes of the given function y = (4e^x+7)/(e^x-1) can be found by analyzing the behavior of the function as x approaches positive or negative infinity. In this function, as x approaches infinity, e^x grows much faster than any constant, so the constants can be considered negligible. Thus, the behavior of the numerator and denominator is dominated by the terms involving e^x. As x tends towards infinity, the function approaches the ratio of the coefficients of e^x, which is 4/1, meaning the horizontal asymptote is y = 4. As x tends towards negative infinity, e^x approaches zero, and the function approaches 7/(-1), so there is also an asymptote at y = -7.

It is given that there is a vertical asymptote at x = -1, where the denominator becomes zero and hence "blows up".

Yes, it is possible for two integers to have no common factors. When two integers have no common factors, they are considered relatively prime or coprime. For example, 15 and 28 are coprime because the only positive integer that divides both numbers is 1.

What is the length of z ?

Answers

it's close to six and it's shorter so 5?

Answer:

The length of z is [tex]3\sqrt{3}[/tex] unit

Step-by-step explanation:

First Label the diagram as shown in the attachment:

In right [tex]\triangle ABC[/tex];

first find the value of y:

Use Pythagoras theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares on the other two sides.

In [tex]\triangle ABC[/tex]

length of AB =6 unit , length of BC =y unit and the length of AC = 3+9 =12 unit

Now, using Pythagoras theorem to get the value of y;

[tex]AB^2+BC^2=AC^2[/tex]

[tex]6^2+y^2=12^2[/tex] or

[tex]36+y^2=144[/tex] or

[tex]y^2=144-36[/tex]=108 or

[tex]y=\sqrt{108}[/tex]

on simplify we get,  [tex]y=6\sqrt{3}[/tex] unit

Therefore, the length of BC is [tex]6\sqrt{3}[/tex] unit.

now, in [tex]\triangle BDC[/tex]

using Pythagoras theorem to find the value of z;

[tex]BD^2+CD^2=BC^2[/tex]

Putting the values of BD = z units , BC = [tex]6\sqrt{3}[/tex] unit and DC = 9 units we have,

[tex]z^2+9^2=(6\sqrt{3})^2[/tex] or

[tex]z^2+81=108[/tex] or

Simplify:

[tex]z^2=27[/tex]  or

[tex]z=\sqrt{27} = 3 \sqrt{3}[/tex]

Therefore, the value of length z is [tex]3\sqrt{3}[/tex] unit

(f o g)(x)= f(g(x)) but [tex] f(x)=(x+2)^{2}[/tex] so in case of f(g(x)) means that we have to eliminate each x in the function f(x) and substitute it with the value of g(x) as the following:

A magazine published a list consisting of the state tax on each gallon of gas. If we add the 50 state tax amounts and then divide by??? 50, we get 27.3 cents. Is the value of 27.3 cents the mean amount of state sales tax paid by all U.S.??? drivers? Why or why??? not?

Answers

Answer: No, it would not be the mean of the tax paid by all US drivers.

To find the mean, we divided by 50 because there are 50 states. However, the number of people in each state is not equal. Therefore, the 50 states should not be treated as they are equal. 

To find the mean correctly, we would have to find weight the value of each state according to the number of people in the state.

Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3).

They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line. 

Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope m = 2/5. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);

Finally, y = (2/5)x + 17/5;

The Mean Absolute Deviation is 17.92.

What is Mean Absolute Deviation?

The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data set. A measure of variance in a data set is the mean absolute deviation.

Take the absolute value of each digit in the data set, then deduct the mean. Next, add up the absolute values. The mean absolute deviation is then calculated by dividing the aforementioned sum by the total number of values in the data set.

Given:

Data set: {20, 24, 12, 44, 68}

Mean of the data = (20+ 24+ 12+ 44+ 68)/ 5 = 168/5

                             = 33.6

Mean Absolute Deviation

= {| 20- 33.6| + |24- 33.6| + |12-33.6| + | 44-33.6| + |68-33.36|} / 5

= (13.6+ 9.6 + 21.6+ 10.4 + 34.4 )/ 5

= 89.6/ 5

= 17.92

Hence, the Mean Absolute Deviation is 17.92.

Samuel paid $720 for a new music system. The list price for the music system was $800. What was his rate of discount?

Answers

the discount rate is 10%
Final answer:

Samuel received a 10% discount on the music system, calculated by finding the difference between the list price ($800) and the sale price ($720), then dividing that by the list price and multiplying by 100.

Explanation:

The question at hand is about calculating the rate of discount Samuel received on his new music system. Initially, the list price of the music system was $800, but Samuel paid $720 for it. To find the rate of discount, we first need to determine the discount amount which is the difference between the list price and the sale price.

List Price = $800Sale Price = $720Discount Amount = List Price - Sale Price = $800 - $720 = $80

Next, to find the rate of discount, we use the formula:

Rate of Discount = (Discount Amount / List Price) × 100

Substituting the values we have:

Rate of Discount = ($80 / $800) × 100 = 10%

Therefore, Samuel received a 10% discount on the music system.
