She has the exact amount of fabric that she needs for this project.
Does Ling have enough fabric for her craft activity?
We know that she is in charge of 40 campers, and she wants to make fabric-covered frames, such that each one needs 1/6 yards of fabric.
We know that he has a total of 6 + 2/3 yards to do this, and we need to see if that is enough.
Now, for each one of the 40 campers she needs 1/6 yards, so the total amount she needs is given by the product:
T = 40*(1/6 yards) = 40/6 yards = (36 + 4)/6 yards = (6 + 4/6) yards
T = (6 + 2/3) yards
So she has the exact amount of fabric that she needs for this project.

The correct statements regarding the linear function in the graph are:
The three points form a straight line.The graph does not pass through the origin.The graph does not a show a proportional relationship.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the points, we have that:
When x changes by 4, y changes by 6.When x changes by 6, y changes by 9.When x changes by 2, y changes by 3.Hence these points form a straight line with a slope of 1.5, that is:
y = 1.5x + b.
When x = 1, y = 3, hence we use it to find b as follows:
3 = 1.5 + b
b = 1.5.
Hence the relation is:

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 3 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 95?
Using the concept of linear equation we can conclude that the number of marbles sold by Mark is 23 and the number of marbles sold by Don is 72.
What is a linear equation?An equation is said to be linear if the highest power of the variable is 1. It is also called as one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variable is x and A is the coefficient of x, while B is a constant.
Let the number of marbles Mark sells be ‘x’
then, the number of marbles Don sells can be given by ‘3x+3’
Total number of marbles sold=95
We can for equation by adding the number of marbles Mark sells and the number of marbles Don sells to the total number of marbles sold. The equation formed is
x+3x+3=95
4x+3=95
4x=95-3
4x=92
x=23
The number of marbles Mark sells =23
Number of marbles Don sells=3x+3
Substituting value of ‘x’
Number of marbles Don sells=(3×23)+3
Number of marbles Don sells=69+3
Number of marbles Don sells=72
Thus, the number of marbles sold by Mark is 23.
While, the number of marbles sold by Don is 72.

Solve for the following equation . x^6-9x^3+10=0
Answer:
x = ∛10x = -∛10/2 +(∛10√3)/2ix = -∛10/2 -(∛10√3)/2ix = -1x = 1/2 -(√3)/2ix = 1/2 +(√3)/2iStep-by-step explanation:
You want to solve the 6th-degree equation x^6 -9x^3 +10 = 0.
QuadraticThe equation is basically quadratic in x^3. Substituting z = x^3, we have ...
z^2 -9z +10 = 0
(z -10)(z +1) = 0 . . . . . factored form
z = 10, z = -1 . . . . . . . values of z that make the factors zero
CubicsNow, we have two cubic equations to solve:
x^3 = 10 ⇒ x = ∛10x^3 = -1 ⇒ x = ∛(-1) = -1The real root is given by the cube root function. The imaginary roots are that value multiplied by 1∠±120° = (-1/2 ±(√3)/2i). Then the six roots are ...
x = ∛10x = -∛10/2 +(∛10√3)/2ix = -∛10/2 -(∛10√3)/2ix = -1x = 1/2 -(√3)/2ix = 1/2 +(√3)/2i__

A certain star is 3.9 x 10^2 light years from the Earth. One light year is about 5.9 x 10^12 miles. How far from the earth (in miles) is the star?
Answer: The star is 2 quadrillion( 1 followed by 15 zeroes) and 301 trillion( 1 followed by 12 zeroes) miles away from Earth. To shorten this into scientific notation(the format used to write large numbers) is: 2.301 x 10^15.
Step-by-step explanation: First, find the exact value of the units of measurement, which in this case is light years. To do so, your best choice would be to separate the equation given for light years. (Note: the line through the middle is just to separate two very similar series of steps.)
1. 5.9 x 10^12 into 5.9 x (10^12)
2. 10^12 = 1,000,000,000,000. 10^12 is the same as adding 11 zeroes since it is multiplying by tens, not 12 zeroes since there is already a zero on the ten. This number is one-trillion(we will shorten this number to 1T).
3. 5.9 x 1T = 5.9 T. Don't get nervous of the big numbers, this is the same as doing 5.9 x 1 and then adding a name afterwards. Now that we have our number, we must remember the question is asking for miles, so keep in mind this large number is the miles.
4. 5.9T --> 5.9 | T Take off the T from 5.9T for now to make this problem a little simpler for this next part.(Note: the | is a separator)
------------------------------------------------------------------------------------------------------------- 5. 3.9 x 10^2 into 3.9 x (10^2)
6. 10^2 = 100. 10^2 is the same as multiplying adding one zero to the ten. This number is one-hundred.
7. 3.9 x 100 = 390. Please remember that this step is to find the number of light years away from the Earth.
8. 390 x 5.9 = 2301. This is the number of lightyears times the number of miles without the zeroes. The next step is to add the zeroes which brings the number into trillions.
9. 2301 | T --> 2301T. Next is to simplify this number, since every zero after 3 makes the number into a different name, this number is now has 15 zeroes. This number(one-quadrillion) will be shortened to Qu.
10-ish. 2301T = 2.301Qu. This is the name of a number with 15-17 zeroes.
10. 2.301Qu = 2.301 x 10^15. This is just turning the number into scientific notation.

How to use composition between two functions and find the domain and range of a function
Let a, b be functions, there is a composition when the independent variable of one of the functions is substituted by the other function. For instance,
a ° b (x) = a [b (x)]
The domain of a function is the set of x-values such that the function exists, whereas the range of it is the set of y-values.
If we know that f(x) = 1 / (2 · x + 1) and g(x) = 1 / x, then the composite functions and their domains are:
f ° g (x)
f ° g (x) = f [g (x)]
f ° g (x) = 1 / [2 · (1 / x) + 1]
f ° g (x) = 1 / [(2 + x) / x]
f ° g (x) = x / (2 + x)
The domain of the composite function is all real numbers except - 2 and the range of the composite function is all real numbers except 1.

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.For this problem, we have that:

A large hotel orders bars of soap to Stocketts rooms once per year if the hotel goes through an average of 750 bars of soap each week how many bars of soap should the hotel order per year
The hotel should order 39000 bars of soap if the hotel goes through on an average of 750 soaps each week.
In everyday terms, an average is one number chosen to represent a list of numbers; it is often the sum of the numbers divided by the number of numbers in the list (the arithmetic mean).
Average is calculated by dividing the sum of the data by the frequency of the data.
Average=sum ÷ frequency
For example if the average of the data set {1,2,3,5,10}=(1+2+3+5+10)÷5=21÷5=4.2
Now for the given question average is given as 750 bars of soap.
We know that there are 52 weeks in a year. ∴ frequency=52
Hence sum of all the averages will give the total number of soap ordered by the hotel in a year.
Sum=average × frequency
or, sum=750 × 52
or, sum=39000 bars of soap.
hence the hotel orders 39000 bars of soap in one year.

What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In item a, the vertex is at (-6,-2), hence:
f(x) = a(x + 6)² - 2
When x = -8, f(x) = -6, hence we use it to find a as follows:
-6 = 4a - 2
4a = -4
a = -1.
Hence:
f(x) = -(x + 6)² - 2.
In item b, the vertex is at (6,2), hence:
g(x) = a(x - 6)² + 2
When x = -2, g(x) = 4, hence we use it to find a as follows:
4 = 64a + 2
64a = 2
