Answer:

The banner is 10 2/3 ft long

Step-by-step explanation:

1 1/3 = 4/3 times the width of the banner:

4/3 * 8 feet wide = 4/3 * 8 = 32/3 = 10 2/3 feet long

The banner is 10 2/3 feet long. :)

The question is asking for the length of a banner, given that the length is 1 1/3 times the width, which is 8 feet. By multiplying 8 feet by 1 1/3, we find that the length of the banner is 10.67 feet.

The question is asking for the length of a banner where the length is 1 1/3 times the width, and the width is given as 8 feet. To find the length of the banner, we need to multiply the width of the banner (8 feet) by 1 1/3, which yields 10.67 feet. Therefore, the length of the banner is 10.67 feet.

Answer:

Conjugate radicals.

Step-by-step explanation:

The two roots a+√b and a-√b are called Conjugate radicals.

Just like in the complex number system where we have complex conjugates such as of 4+7i and 4 - 7i, the radicals also have their conjugate radicals. The conjugate radical of a+√b is simply obtained by changing the sign of the radical part of the expression to obtain a-√b. Therefore, the two expressions given are conjugate radicals

Answer:

Conjugate.

Step-by-step explanation:

The difference is in the signs. They are conjugate radicals.

Answer:

D. y = 10000 - 750x

Step-by-step explanation:

The answer is D. y = 10000 - 750x, where:

y = the current value of the car,

10000 is the initial value of the car

750 is the depreciation it has every year

x is the number of years.

The 10000 has to be fixed and not multiplied by anything (unlike answer A or C) because that's the initial value of the car.  Then it has to be reduced (meaning we take value of out it, so a subtraction), so that excludes A and B.  The devaluation occurs every year, so it has to be multiplied by the number of years (excluding answers A and C again).  So, only answer D remains.

Final answer:

The equation that best models the depreciation of the car is: y = 10000 - 750x. This equation represents the value of the car decreasing by $750 each year.

Explanation:

The equation that best models the depreciation of the car is: y = 10000 - 750x.

This equation is derived from the given information that the car depreciates by $750 each year, which is a constant amount. The equation represents the value of the car, denoted by 'y', decreasing by $750 for each year, denoted by 'x'.

For example, if we plug in x = 1 into the equation, we get y = 10000 - 750(1) = 9250, which means the car is worth $9250 after the first year.

You will notice that the answer to problem 8 does not agree with any of the offered choices. The time period of 22.8 years is 12 times the half-life of the substance, so there will be (1/2)^12 = 1/4096 of the original amount remaining. The time periods corresponding to the amounts shown range from 1.37 years to 16.4 years.

For half-life problems, I find it convenient to use the decay factor (0.5^(1/half-life)) directly, rather than convert it to e^-k. If you do convert it to the form ...

  e^(-kt)

the value of k is (ln(2)/half-life), about 0.3648143056.

step 3

Convert to standard form

Remember that the equation of the line into standard form is equal to

Note The complete answers in the attached file

The answer is:

The equation D  will produce the shown circle.

[tex]6x^{2}+6y^{2}=144[/tex]

Since the graph is showing a circle, we need to find the equation of a circle that has a radius which is between 0 and 5 units, and has a center located at the origen (0,0).

Also, we need to remember the standard form of a circle:

[tex](x+h)^{2} +(y+k)^{2}=r^{2}[/tex]

Where,

x, is the x-coordinate of the x-intercept point

y, is the y-coordinate of the y-intercept point

h, is the x-coordinate of the center.

k, is the y-coordinate of the center.

r, is the radius of the circle.

So, discarding each of the given options, we have:

First option:

A.

[tex]\frac{x^{2} }{20}+ \frac{y^{2} }{20}=1\\\\\frac{1}{20}(x^{2}+y^{2})=1\\\\x^{2}+y^{2}=20*1\\\\x^{2}+y^{2}=20[/tex]

Where,

[tex]radius=\sqrt{20}=4.47=4.5[/tex]

Now, can see that even the center is located at the point (0,0), the radius of the circle is equal to 4.5 units and from the graph we can see that the radius of the circle is more than 4.5 units but less than 5 units, the option A is not the equation that produces the shown circle.

Second option:

B.

[tex]20x^{2} -20y^{2}=400\\\\\frac{1}{20}(x^{2} -y{2})=400\\\\x^{2} -y{2}=400*20[/tex]

Where,

[tex]radius=\sqrt{8000}=89.44units[/tex]

We can see that even the center is located at the point (0,0), the radius of the circle is 89.44 units, so, the option B is not the equation that produces the shown circle.

Third option:

C.

[tex]x^{2}+y^{2}=16[/tex]

Where,

[tex]radius=\sqrt{16}=4units[/tex]

We  can see that even the center is located at the point (0,0), the radius of the circle is 4 units, which is less than the radius of the circle shown in the graph, so, the option C is not the equation that produces the shown circle.

D.

[tex]6x^{2}+6y^{2}=144\\\\6(x^{2} +y^{2})=144\\\\x^{2} +y^{2}=\frac{144}{6}=24\\\\[/tex]

Where,

[tex]radius=\sqrt{24}=4.89units[/tex]

Now, we have that the radius of the circle is 4.89 units, which is approximated equal to 0, also, the center of the circle is located at (0,0) so, the equation D will produce the shown circle.

[tex]6x^{2}+6y^{2}=144[/tex]

Have a nice day!

The equation that represents the given graph is:

              [tex]6x^2+6y^2=144[/tex]

By looking at the given graph we observe that the graph is a circle with center at (0,0) and the radius is close to 5.

Now, we know that:

The general equation of a circle with center (h,k) and radius r is given by:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here (h,k)=(0,0)

Hence, the equation of the circle is:

            [tex]x^2+y^2=r^2[/tex]

A)

[tex]\dfrac{x^2}{20}+\dfrac{y^2}{20}=1\\\\i.e.\\\\x^2+y^2=20[/tex]

i.e.

[tex]x^2+y^2=(2\sqrt{5})^2[/tex]

This equation is a equation of a circle with center at (0,0)

and radius is: [tex]2\sqrt{5}\ units[/tex]

i.e. the radius is approximately equal to 4.5 units.

But the radius is close to 5.

Hence, option: A is incorrect.

B)

[tex]20x^2-20y^2=400\\\\i.e.\\\\x^2-y^2=20[/tex]

This is not a equation of a circle.

This equation represents a hyperbola.

Hence, option: B is incorrect.

C)

[tex]x^2+y^2=16[/tex]

which could be represented by:

[tex]x^2+y^2=4^2[/tex]

i.e. the radius of circle is: 4 units

which is not close to 5.

Hence,option: C is incorrect.

D)

[tex]6x^2+6y^2=144[/tex]

On dividing both side of the equation by 6 we get:

[tex]x^2+y^2=24[/tex]

i.e.

[tex]x^2+y^2=(\sqrt{24})^2[/tex]

i.e.

Radius is: [tex]\sqrt{24}\ units[/tex]

which is approximately equal to 4.9 units which is close to 5 units.

For this case we have that by definition, the slope of a line is given by:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

Two points are needed through which the line passes:

[tex](x_ {1}, y_ {1}): (- 1.75; 14.5)\\(x_ {2}, y_ {2}}: (- 1; 4.4)[/tex]

Substituting:[tex]m = \frac {4.4-14.5} {- 1 - (- 1.75)}\\m = \frac {-10.1} {0.75}\\m = -13.46666666[/tex]

Rounding:

[tex]m = -13.47[/tex]

Answer:

[tex]m = -13.47[/tex]

Answer:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Two points are needed through which the line passes:

(x_ {1}, y_ {1}): (- 1.75; 14.5)\\(x_ {2}, y_ {2}}: (- 1; 4.4)

Substituting:m = \frac {4.4-14.5} {- 1 - (- 1.75)}\\m = \frac {-10.1} {0.75}\\m = -13.46666666

Rounding:

m = -13.47

Answer:

18% reduction leaves 82% remaining. 82% of $2150 = .82(2150) = $1763.

Answer:

Retail Price = $1763

Step-by-step explanation:

List price of article = $2150

Percentage discount given = 18%

Then value of discount on the list price = 18% of $2150

                                                                 = [tex]\frac{(2150)(18)}{100}[/tex]

                                                                 = $387

Now the retail price of the article = List price - discount given

                                                       = $2150 - $387

                                                       = $1763

Therefore, Retail price of the article will be $1763

Andy earns $8.50 per hour by dividing the total amount he earns ($34).

To find out how much Andy earns for each hour he works, you need to divide the total amount he earns by the number of hours he works on Saturday morning. If Andy earns $34 over 4 hours, his hourly wage is calculated as follows:

Divide $34 by 4 hours.

$34 / 4 hours = $8.50 per hour.

So, Andy earns $8.50 per hour.

Answer:

1

Step-by-step explanation:

y-intercept is defined as the point where the graph crosses the y-axis. The value of x coordinate at this point is zero, as along entire y-axis, the value of x coordinate is always zero. So substituting x = 0 in the function will give us the y-coordinate of the y-intercept of the given function.

[tex]f(x)=x^{3}-x^{2} -x+1[/tex]

Substituting x = 0 in this function, we get:

[tex]f(0)=0^{3}-0^{2}-0+1=1[/tex]

Thus, the y-coordinate of the y-intercept is 1. Therefore the y-intercept of the function in ordered pair will be: (0, 1)

Move the 5 to the other side:

[tex]2\sec(x)=1-5=-4[/tex]

Divide both sides by 2:

[tex]\sec(x) = -2[/tex]

Recall the definition:

[tex]\sec(x)=-2 \iff \dfrac{1}{\cos(x)}=-2[/tex]

Invert both sides

[tex]\cos(x) = -\dfrac{1}{2}[/tex]

This is true when

[tex]x=\pm \dfrac{\pi}{3}[/tex]

If you need both angles to be in [0,2pi], you can recall

[tex]\cos\left(-\dfrac{\pi}{3}\right) = \cos\left(-\dfrac{\pi}{3}+2\pi\right) = \cos\left(\dfrac{5\pi}{3}\right)[/tex]

Answer:

Your answer would be 3/7 or [tex]\frac{3}{7}[/tex]

____________________________________________________

Step-by-step explanation:

In this type of question, we would need to find out the chances of getting something as an outcome, and that would be expressed as a fraction.

In order to find out the chance (or likeliness) of an outcome, we would need o use the information provided in the question.

Let's give you some key information that was given to us.

Key information:

4 animal characters

3 Human characters

With the information above, we can figure out what would be the probability of an outcome.

The question is saying "what is the probability of the computer picking a human character." That means that the amount of human characters would go on our numerator.

There's not only human characters, but there are 4 animal characters too, so that would be used to give us our total. the "4" will be added to our denominator.

Now, let's write it in a fraction.

Fraction: [tex]\frac{numerator}{denominator}[/tex]

We know that we are trying to find the probability of getting a human character, so "3" would go on our numerator.

For our denominator, we would add up both numb ers since it would have to be the total amount of options in order to find the probability, and that would be "7" since 4 + 3 = 7.

When you put those into a fraction. Your FINAL answer would be:

3/7 or [tex]\frac{3}{7}[/tex]

Step-by-step explanation:

The meeting is not mandatory and only volunteers are participating in the task he wanted, this shows bias and doesn't correctly represent the whole team.

Answer:

  40π/3 cm^2

Step-by-step explanation:

The centerline of the shaded region has a radius of 3 +4/2 = 5 cm. Its length is 1/3 of a circle with that radius, so is ...

  length of centerline = (1/3)(2π·5 cm) = (10/3)π cm

The shaded region is 4 cm wide, so the area is the product of that width and the centerline length:

  (4 cm)(10/3 π cm) = 40π/3 cm^2

Answer: first option.

Step-by-step explanation:

Given the right triangle shown in the figure, to calculate the measure of the angle m∠C, you can use the inverse function of the cosine:

[tex]\alpha=arccos(\frac{adjacent}{hypotenuse})[/tex]

You can identify in the figure, that, for the angle ∠C:

[tex]\alpha=\angle C\\adjacent=7\\hypotenuse=15[/tex]

Then, since you know the lenght of the adjacent side and the lenght of the hypotenuse, you can substitute these values into  [tex]\alpha=arccos(\frac{adjacent}{hypotenuse})[/tex].

Therefore, the measure of the angle ∠C is:

[tex]\angle C=arccos(\frac{7}{15})\\\\\angle C=62.2\°[/tex]

Answer: Option B

[tex]y=0.5x +0.75[/tex]

Step-by-step explanation:

The equation modeling this situation is a linear equation of the form

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

Where x is the slope and b is the intercept with the y axis.

To find the equation of a line we need two points that belong to the line.

We know that when it is empty the jug weighs 0.75 lib.

This is:

When x = 0, y = 0.75

Then when the jug contains 3 cups of water it weighs 2.25 pounds.

This is:

When x = 3, y = 2.25

We already have the two points

Then we find the slope of the straight

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]y_2 = 2.25\\\\y_1=0.75\\\\x_2=3\\\\x_1=0[/tex]

[tex]m=\frac{2.25-0.75}{3-0}[/tex]

[tex]m = 0.5[/tex]

The equation is:

[tex]y=0.5x +b[/tex]

We substitute the point (0, 0.75) in the equation and solve for b

[tex]0.75=0.5(0) +b[/tex]

[tex]b=0.75[/tex]

Finally the equation is:

[tex]y=0.5x +0.75[/tex]

Answer:

2118 dollars

Step-by-step explanation:

His capital gain is the difference in the (sell - buy) prices multiplied by the number of shares (120).

120 * (85.89 - 68.24) = 120 * 17.65 = 2118

The capital gain is a short term gain (held under a year)

The amount is 2118 dollars.
