Using Squeeze/Sandwich Theorem,
Calculate the limit of : lim [(x,y) -> (0,0)] (3 . x^2 . y / (x^2 + y^2))
Answer: We can use the Squeeze theorem to find the limit.
We know that:
x^2 + y^2 >= 0 for all (x, y)
Also,
|3xy| <= 3|x||y| <= 3x^2 + 3y^2
So,
|3xy/(x^2 + y^2)| <= 3(x^2 + y^2)/(x^2 + y^2) = 3
As we approach (x, y) = (0, 0), x^2 + y^2 becomes arbitrarily close to 0, so the right-hand side of the inequality becomes arbitrarily close to 3, and the left-hand side becomes arbitrarily close to 0.
Therefore,
lim[(x,y)->(0,0)] (3xy/(x^2+y^2)) = 0
Hence, by the sandwich theorem, we can say that the limit of the function is 0.

A rectangular box, half filled, holds 200 cubic feet of grain. If the box is 8 feet wide and 5 feet long, how deep is it?
The rectangular bin has a depth of 20 feet.
A cuboid is a three-dimensional shape with rectangles on all sides. A cuboid has six faces, eight vertices, and twelve edges. All of the angles formed at a cuboid's vertices are right angles. The opposing edges are perpendicular to each other.
For the given situation,
A rectangular bin is in the shape of a cuboid.
Volume of the rectangular bin, V = 1200 cubic feet
Length of the rectangular bin ,l = 10 feet
Width of the rectangular bin,w = 6 feet
Let the height of the rectangular bin be h.
The formula of volume of cuboid is
[tex]v=lwh[/tex]
Now substitute the above values,
⇒ 1200= (10)(6)h
⇒ [tex]h=\frac{1200}{60}[/tex]
⇒ h= 20
Hence we can conclude that the rectangular bin is 20 feet deep.

The depth of the box is found through the volume formula for a rectangular prism, which involves multiplying the length, width and depth. Knowing the volume when half-filled, and the length and width, we can calculate the box is 10 feet deep.
Explanation:This problem deals with the concept of volume in mathematics. First, the formula for the volume of a rectangular prism (or a box) is length multiplied by width multiplied by height. In this case, we know that the box is half filled with grain and that the total volume of that grain is 200 cubic feet. So, if the box was filled completely, it would have a volume of twice that, or 400 cubic feet.
Now we know that the box's volume is 400 cubic feet and its length is 8 feet and width is 5 feet. So to find the height (which is what we're calling 'depth' in this case), we can use our volume formula. We divide the total volume by the product of the length and width (400/40) to find the height or depth, resulting in a depth of 10 feet.

What is the amplitude of the sinusoidal function?
Answer: 4
Step-by-step explanation: Amplitude has to do with how high and low the function goes according to the midline. The midline for this function is at -3. The maximum point is 1, and the minimum point is -7. The function goes up 4 units and down 4 units
Answer:
Amplitude = 4
Step-by-step explanation:
The amplitude of a sinusoidal function is the height (vertical distance) from the midline to the peak (or trough).
To calculate the amplitude, simply divide the vertical distance between the maximum and minimum y-values by 2.
From inspection of the given graph:
Maximum y-value = 1Minimum y-value = -7Therefore:

A book sold 34,500 copies in its first month of release. Suppose this represents 9.8% of the number of copies sold to date. How many copies have been sold to
date?
Round your answer to the nearest whole number.
Answer: If 34,500 copies sold in the first month of release represent 9.8% of the number of copies sold to date, we can use this information to find the total number of copies sold to date. We can set up the equation as:
(34,500 copies) / (9.8%) = (Total number of copies sold to date)
To solve for the total number of copies sold to date, we can cross-multiply and divide by 0.098:
(34,500 copies) * (100%) / (9.8%) = (Total number of copies sold to date)
(34,500 copies) * (100/9.8) = (Total number of copies sold to date)
This simplifies to:
(34,500 copies) * 10.20408163 = (Total number of copies sold to date)
Total number of copies sold to date = 353878.163.
Rounding the answer to the nearest whole number we get:
Total number of copies sold to date = 353878.
So the book has sold 353878 copies to date.

2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
23p – 101 = 65p – 40 – p
2.3p – 14.1 = 6.4p – 4
230p – 1010 = 650p – 400 – p and 2.3p – 10.1 = 6.49p – 4 are the equations after rewriting their properties have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p.
What is equations?As with other words like "equal," "equality," and "equate," the word "equa" at the start of the equation will sound familiar to you. Making things balance out is the theme of all these words. A statement of two quantities' equality is expressed by an equation.
You might still attempt to make the two sides equal even if the equation is not mathematical but rather, say, interpersonal. It might be simpler for two people to decide to remain together for a while if marriage is removed from the picture, for instance.
Given the equation 2.3p – 10.1 = 6.5p – 4 – 0.01p
When multiplied by 100, it becomes
230p – 1010 = 650p – 400 – p
And 6.5p - 0.01p = 6.49p
So, 2.3p – 10.1 = 6.49p – 4
Thus, 230p – 1010 = 650p – 400 – p and 2.3p – 10.1 = 6.49p – 4 are the equations after rewriting their properties have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p.

Using the rate of the exponential growth to calculate the exponential function, the number of subscribers after 10 years is 3446
What is an Exponential FunctionAn exponential function is a function in which the variable appears in an exponent. It is of the form f(x) = aˣ, where a is a constant and x is the independent variable. The graph of an exponential function is a curve that increases or decreases at an increasing rate.
To solve this problem, we have to find the rate and then calculate the number subscribers after 10 years.
In a given exponential function;
A = P(1 + x)ⁿ
Since this is an exponential growth, we can calculate the rate as;
1 year = 250 subscriber
2 years = 3 * 250
rate = (250 / 750) * 100
rate = 30%
We can substitute the values into the formula and solve
A = 250(1 + 0.3)¹⁰
A = 3446.46

Step-by-step explanation:
Adrian has enough money to buy 3 cd's at $16 each. If the cd's are on a sale and are sold at a discount price of $12, he can buy more cd's because the price is cheaper. To find out how many more cd's he can buy, you can subtract the original cost of the cd's from the sale price of the cd's and then divide that amount by the sale price of the cd's.
3 cd's x $16 = $48
$48 - $12 = $36
$36 / $12 = 3
