Find the limit, if it exists. (if an answer does not exist, enter dne.) lim (x, y) → (0, 0) x4 − 20y2 x2 + 10y2
The limit of the expression as (x, y) approaches (0, 0) does not exist.
Explanation:To find the limit as (x, y) approaches (0, 0) of the expression \(\frac{x^4 - 20y^2}{x^2 + 10y^2}\), we can try approaching the limit along different paths. Let's consider approaching along the x-axis (y=0) and along the y-axis (x=0) separately.
Approaching along the x-axis: \(\lim_{{(x, 0) \to (0, 0)}} \frac{{x^4 - 20(0)^2}}{{x^2 + 10(0)^2}} = \lim_{{(x, 0) \to (0, 0)}} \frac{{x^4}}{{x^2}} = \lim_{{(x, 0) \to (0, 0)}} x^2 = 0.
Approaching along the y-axis: \(\lim_{{(0, y) \to (0, 0)}} \frac{{(0)^4 - 20y^2}}{{(0)^2 + 10y^2}} = \lim_{{(0, y) \to (0, 0)}} \frac{{-20y^2}}{{10y^2}} = \lim_{{(0, y) \to (0, 0)}} -2 = -2.
Since the limit approaches different values along different paths, the limit does not exist.

17 ÷ 4520= what is the product
The student's question is related to dividing 17 by 4520. This is performed by a straight division resulting in a small decimal quotient, not a product. The calculation is best done using a calculator and rounding to the proper number of significant figures.
The equation given, 17 by 4520, is asking for the result of dividing 17 by 4520. To compute this, we simply perform the division, recognizing that since 4520 is much larger than 17, the answer will be a very small decimal value. The term 'product' in the student's question seems to be a mistake, as they are likely referring to the quotient obtained from the division.
When attempting to perform the computation mentally and simplify the process, one might attempt to find numbers that are more easily divisible or apply scientific notation to simplify calculations, much like re-expressing numbers to make them more manageable. However, for this division, no mental math trick simplifies it effectively, and using a calculator might be the best option.
When going through this process, it is also important to consider significant figures when giving the final answer, rounding as necessary based on the precision of the data provided.

Over a two hour time period a snail moved 76 inches. How far is this in yards? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.
Final answer:
The snail moved a total distance of 2 1/9 yards after converting 76 inches to yards using the conversion factor of 1 yard equals 36 inches.
Explanation:
To convert the distance a snail moved from inches to yards, we use the conversion factor that 1 yard equals 36 inches. Given that the snail moved 76 inches, we divide this number by 36 to find the distance in yards.
76 inches ÷ 36 inches/yard = 2 yards and 4 inches.
Since there are 36 inches in a yard, the remaining 4 inches must be converted to a fraction of a yard by dividing by 36:
4 inches ÷ 36 = 1/9 yard.
Therefore, the snail moved 2 yards and 1/9 yard, or 2 1/9 yards in total.

A random variable x takes four possible values, 0, 2, a, and b, where a and b are unknown numbers. if pr[x = 0] = 0.2, pr[x=2] = 0.4, pr[x = a] = 0.3, e[x] = 2.8 and it is the case that a + b = 6, what is the missing value of a ?
a.-1.0
b.5.0
c.7.0
d.cannot be determined without more information
e.none of the above
Final answer:
The missing value of the random variable X can be determined by solving the equation e[x] = 2.8 and substituting the known values. By solving the equation, we find that the missing value is c. 7.
Explanation:
a. In words, X = A random variable that takes four possible values: 0, 2, a, and b.
b. X~ A missing value that represent an unknown number for the random variable X.
c. In words, X = The missing value of the random variable X, denoted by a.
d. X A missing value that we need to determine.
In this case, the missing value of a can be found by substituting the known values into the equation a + b = 6. Since b = 6 - a, we can substitute this expression into the equation e[x] = 2.8 and solve for a. From the equation, we get 0.2(0) + 0.4(2) + 0.3(a) + 0.3(6 - a) = 2.8.
Solving this equation gives us a = 7. Therefore, the missing value of a is 7, so the correct answer is c.

Anjali went to Citizens Bank and borrowed $7,000 at a rate of 8%. The date of the loan was September 20. Anjali hoped to repay the loan on January 20. Assuming the loan is based on ordinary interest, Anjali will pay back how much interest on January 20? A. $187.18 B. $187.17 C. $189.78 D. $188.22
Answer:
$189.78
Step-by-step explanation:
"The computation of the interest on January 20 is shown below:
= Principal × interest rate × number of days ÷ total number of days in a year
= $7,000 × 8% × 122 days ÷ 360 days
= $7,000 × 8% × 0.338
= $189.78
The 122 days are calculated below:
September - 10 days
October - 31 days
November - 30 days
December - 31 days
January - 20 days
Total - 122 days
And we assume the 360 days in a year"

Elizabeth has $252.00 in her account on Sunday. Over the next week, she makes the following changes to her balance via deposits and purchases: Day Debit ($) Credit ($) Monday 114.60 150.00 Tuesday 79.68 --- Wednesday 161.39 --- Thursday 57.40 --- Friday 22.85 75.00 Saturday 140.55 --- On what day does Elizabeth first get charged an overdraft fee?
Given:
Elizabeth has $252.00 in her account on Sunday and a table is given of her deposits and purchases over the following week.
To Find:
The day Elizabeth first gets charged an overdraft fee.
Answer:
Thursday's expenditure of $57.40 exceeds her bank balance at the time of transaction, and therefore Thursday is the day Elizabeth would first get charged with an overdraft fee.
Step-by-step explanation:
Elizabeth would first get charged with an overdraft fee when her expenditure exceeds her bank balance, i.e., the amount that is debited is more than what is in her bank account at that particular time.
So we analyse her transactions one by one.
On Sunday, we are given that she has $252.
On Monday, $114.60 is debited. So the remaining balance would be
$252 - $114.60 = $137.4
But on the same day, $150 is also credited to her account. So her balance would then be
$137.4 + $150 = $287.4
Next, on Tuesday, $79.68 is debited so the balance she is left with would be
$287.4 - $79.68 = $207.72
On Wednesday, $161.39 is debited so the balance she is left with would be
$207.72 - $161.39 = $46.33
On Thursday, $57.40 is debited so the balance she is left with would be
$46.33 - $57.40 = -$11.07
Thus, we see that Thursday's expenditure of $57.40 exceeds her bank balance and therefore Elizabeth would be charged with an overdraft fee as her bank balance after the transaction would be -$11.07.

factor the expression 10x−25y
Final answer:
To factor the expression 10x-25y, we find the greatest common factor, which is 5, and write the expression as 5(2x - 5y).
Explanation:
To factor the expression 10x−25y, we need to find the greatest common factor (GCF) that both terms share. In this case, both terms are divisible by 5. When we factor out the GCF, we get:
Identify the GCF of 10x and 25y, which is 5.
Divide both terms by the GCF: 10x/5 = 2x and 25y/5 = 5y.
Write the factored expression: 5(2x - 5y).
Thus, the expression 10x−25y factored is 5(2x - 5y)

a pail hold 6 3/4 gallon of water. how much is this in cups
The required, there are 108 cups of water in the pail as a pail hold 6 3/4 gallon of water.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
Here,
To convert 6 3/4 gallons to cups, we can use the fact that there are 16 cups in one gallon.
So, we can start by multiplying 6 (the number of whole gallons) by 16 to get the number of cups in those gallons:
6 gallons × 16 cups/gallon = 96 cups
Next, we need to convert the 3/4 of a gallon to cups. To do this, we can multiply the fraction by the number of cups in one gallon:
3/4 gallon × 16 cups/gallon = 12 cups
So, the total amount of water in the pail is:
96 cups + 12 cups = 108 cups
Therefore, there are 108 cups of water in the pail.
