The Formula for chain rule is dy/dx = dy/du x du/dx
The chain rule is a formula used in differential calculus to get the derivative of a composite function. According to the chain rule, if y = f(g(x)), then the instantaneous rate of change of function f with respect to g and g with respect to x leads in an immediate rate of change of f in relation to x. As a result, y' = f'(g(x)) will be supplied as the derivative of y. g'(x). One of the crucial rules in differentiation is the chain rule.
The chain rule formula is as follows for the function y = f(x), where f(x) is a composite function such that x = g(t):

Therefore ,the true bearing of the plane and its speed is ∝=-71.9° and 324.31 mph
What is vector?A thing with both magnitude and direction is called a vector. A vector can be visualized geometrically as a directed line segment, where the direction is indicated by an arrow and the length of the segment equals the magnitude of the vector. From the vector's tail to its head is the direction of motion. According to the definition of a resultant vector, a single vector is one that has the same result as several other vectors taken together.
Here,
To find the true bearing of the plane and its speed.
We find the vector component,
Since N75°W is same as 95°+90°=165°
Thus,
f(x)=300cos100 +50cos165 = -100.39
f(y)=300sin100 +50sin165= 308.38
next we find resultant
R=[tex]\sqrt{f(x)^{2}+f(y)^{2} }[/tex]
R=[tex]\sqrt{(-100.39)^{2}+(308.38)^{2} }[/tex]
R=[tex]\sqrt{105178.35}[/tex]
R=324.31 mph
The bearing of the plane=> ∝=[tex]tan^{-1}[/tex](308.38/-100.39)
So ∝=-71.96°
Therefore ,the true bearing of the plane and its speed is ∝=-71.96° and 324.31 mph

Your monthly take-home pay is $
The monthly take home pay if your take-home pay is calculated as 46 hours per week; is $2,606.6.
What is monthly take home pay?
The amount of money left over after taxes, benefits, and other deductions from a paycheck is known as take-home pay. It is the difference left over after subtracting all gross income deductions.
Let,
Number of hours per week = 46 weeks.
Regular hourly wage up to 40 hours = $15.90
Wage up to 40 hours = 40 x 15.90 = $636
Hours over 40 hours, wage is 1.5 times as much
Wage of hour 41 - 46 = 6 x 1.5 x 15.90 = $143.10
Total weekly wage = 636 + 143.10 = $779.10
Since 1 month = 4.345 weeks.
Therefore,
Monthly wage = Weekly wage x 4.345
= 777.10 x 4.345
Monthly wage = $3385.19
Now maximum and assurance = 23% of monthly wage
= 23% of 3385.19
= 0.23 x 3385.10
= $778.59
Therefore,
Monthly take home pay = Monthly wage - Tax
= $3385.19 - $778.59
Monthly take home pay = $2606.6
Hence, the monthly take home pay if your take-home pay is calculated as 46 hours per week; is $2,606.6.

Irlene invested $3,500 in a high-interest savings account for three years. For the first year, the interest rate was 9% compounded semi-annually. For the second year the rate became 5.25% with the same compounding period. For the third year the rate remained the same but it was compounded quarterly. What was the value of the investment at the end of the third year? For full marks your final answer should be rounded to the nearest cent.
Rounded to the nearest cent, the final value of Irlene's investment at the end of the third year is $4,431.78.
What is the easiest way to define interest rate?A percentage of the principal, or the amount loaned, is what a lender charges a borrower as interest. The annual percentage rate, or APR, is the usual unit used to express the interest rate on a loan (APR).
To calculate the value of Irlene's investment at the end of the third year, you can use the formula for compound interest:
FV = PV * (1 + r/n)^(n*t)
Where:
FV is the future value of the investment (what you want to find)
PV is the present value of the investment (the initial amount, $3,500)
r is the annual interest rate (the rate for the third year is 5.25%)
n is the number of compounding periods per year (for the first year it was 2, for the second year it was 2, and for the third year it was 4)
t is the number of years the money is invested (3 years in this case)
Plugging the values into the formula, you get:
FV = $3,500 * (1 + 5.25%/2)^(23) * (1 + 5.25%/4)^(41)
= $3,500 * (1.0263)^6 * (1.0131)^4
= $3,500 * 1.1496 * 1.0534= $4,431.77

Cumulative markup percent for department at the end is 23.1%.
The men's furnishing department had an opening inventory of $168,000 at cost with a markup of 48.5%
Cumulative markup is the difference between the total wholesale cost and total retail price of all merchandise handled during a given period of time.
cumulative markup dollars are the total markup dollars on all merchandise for a selected selling period. To calculate cumulative markup dollars and cumulative markup percent, the following formulas are utilized by the retailer:
Cumulative Markup $ = Total Retail $ - Total Cost $
Cumulative Markup % = Cumulative Markup $ ÷ Cumulative Retail $
Steps for calculating cumulative markup percentage for the specified period of time:
Step 1. Calculate the unknown retail value for either opening inventory or purchases.
Step 2. Calculate total retail of opening inventory and purchases.
Step 3. Calculate the unknown cost value for either opening inventory or purchases.
Step 4. Calculate total cost of opening inventory and purchases.
Step 5. Calculate total markup dollars.
Step 6. Calculate cumulative markup percent for the specified period of time.
For opening inventory
retail = $168,000
cost = 168,000*48.5/100 = $81480
For purchases
retail = 80,000*52.5/100 = $42000
cost = $80,000
total retail of opening inventory and purchase =
168,000+42000 = $210000
total cost of opening inventory and purchase =
81480+80,000 = $161480
total markup = total retail - total cost
total markup = 210000-161480 = 48520
cumulative markup percent = (total markup/ total retail)
= (48520/210000)*100
= 0.23104761904*100
=23.1%

prove that the composition of two isometries is an isometry and the inverse of an isometry is an isometry.
The composition of two isometries is an isometry.
Proof:
Let T1 and T2 be isometries. T1(A) = A' and T1(B) = B'. Therefore by isometry T1, AB = A'B'
T2(A) = A'' and T2(B) = B''. Therefore by isometry T2, AB = A''B''
T2 º T1 = T2(T1(A)) = T2(A') = A'''. T2 º T1 = T2(T1(A)) = T2(B') = B'''. Therefore under composition AB = A'''B''' and distance is preserved.
The inverse of an isometry is an isometry.
Proof:
Given T and isometry. This means T(A) = A' and T(B) = B' with AB = A'B'
The inverse of T, T⁻¹maps A' to A and B' to B, so A'B' maps to AB.

line y = 2. How are the x-coordinates of corresponding points in
the image and the preimage related?
After reflecting the quadrilateral EFGH across the line y = 2, the x-coordinates of the corresponding points in the image and the preimage will be the same.
What is Reflection?Generally, Reflection is an isometry, which means that it preserves distance and angles. Therefore, the x-coordinates of the points in the image and the preimage will not be changed by the reflection. The y-coordinates will change since the reflection flips the points over the line of reflection.
For example, if quadrilateral EFGH has a vertex at (x, y), then the corresponding vertex in the image will be at (x, 2 - y). The x-coordinate remains the same, but the y-coordinate is reflected across the line y = 2.

Last week,Barry's Swimwear sold/15 of its bathing suits in stock .Philip's Sun Wear sold 5 out of 72 of its bathing suits in stock. Which store sold a greater fraction of the bathing suits in stock?
Answer: Barry's Swimwear sold a greater fraction of the bathing suits in stock as long as the store had fewer than 72 bathing suits in stock.
Step-by-step explanation:
Barry's Swimwear sold 15 out of an unknown number of bathing suits in stock, so we can express this fraction as 15/x, where x is the total number of bathing suits in stock at Barry's Swimwear. Similarly, Philip's Sun Wear sold 5 out of 72 bathing suits in stock, so we can express this fraction as 5/72.
To compare these two fractions, we need to express them with a common denominator. One way to do this is to find the least common multiple of the two denominators, which in this case is 72. To express 15/x with a denominator of 72, we can multiply both the numerator and the denominator by a factor of 72/x. This results in the fraction 15*(72/x)/72 = 15/x. Similarly, we can express 5/72 with a denominator of 72 by multiplying both the numerator and the denominator by a factor of 72/72, which results in the fraction 5*(72/72)/72 = 5/72.
Now that we have both fractions expressed with a common denominator of 72, we can compare them directly. 15/x is greater than 5/72 as long as x is less than 72. This means that Barry's Swimwear sold a greater fraction of the bathing suits in stock as long as the store had fewer than 72 bathing suits in stock.
