EX24) 29 du Use the chain rule to find the indicated derivative. og, where du g(u, v) = f(x(u, v),y(u, v)), f(x,y) = 7x³y³.x(u, v) = ucosv, y(u, v) = usiny = 56u² cos v sin³ v
∂g/∂u is equal to 21u⁵cos⁴(v)sin⁴(v)(cos(v) + u³cos⁴(v)sin²(v)sin(v)).
To find the indicated derivative, we need to use the chain rule. Let's differentiate step by step:
Given:
g(u, v) = f(x(u, v), y(u, v))
f(x, y) = 7x³y³
x(u, v) = ucos(v)
y(u, v) = usin(v)
To find ∂g/∂u, we differentiate g(u, v) with respect to u while treating v as a constant:
∂g/∂u = (∂f/∂x) * (∂x/∂u) + (∂f/∂y) * (∂y/∂u)
To find ∂f/∂x, we differentiate f(x, y) with respect to x:
∂f/∂x = 21x²y³
To find ∂x/∂u, we differentiate x(u, v) with respect to u:
∂x/∂u = cos(v)
To find ∂f/∂y, we differentiate f(x, y) with respect to y:
∂f/∂y = 21x³y²
To find ∂y/∂u, we differentiate y(u, v) with respect to u:
∂y/∂u = sin(v)
Now, we can substitute these partial derivatives into the equation for ∂g/∂u:
∂g/∂u = (21x²y³) * (cos(v)) + (21x³y²) * (sin(v))
To find the simplified form, we substitute the given values of x(u, v) and y(u, v) into the equation:
x(u, v) = ucos(v) = u * cos(v)
y(u, v) = usin(v) = u * sin(v)
∂g/∂u = (21(u * cos(v))²(u * sin(v))³) * (cos(v)) + (21(u * cos(v))³(u * sin(v))²) * (sin(v))
Simplifying further, we get:
∂g/∂u = 21u⁵cos⁴(v)sin⁴(v)(cos(v) + u³cos⁴(v)sin²(v)sin(v))

√x+7= -2
√x+7 The solution to the equation is x=-3.
Square root: If we take the square root of a number and then take the square of the outcome, we get the original number back again.
e.g. 4 = 2 and 22 = 4.
We can say that the square root and the square cancel each other out. They are the inverse of each other.
If we have a number written with the index 2 ( squared) then taking the square root simply means that we leave out the 2 ( this only applies to positive numbers ).
We can therefore take any squared numbers that are under the square root sign out from under the root sign by leaving out the power 2.

if an aircraft is certificated with 275 seats, but only 249 passengers are aboard for that flight segment, how many flight attendants are required? group of answer choices 6 4 7 5
5 flight attendants are required.
The number of flight attendants required on an aircraft is determined by regulatory agencies such as the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA) in Europe.
The number of flight attendants depends on several factors, including the type of aircraft, the number of passenger seats, the length of the flight, and the number of passenger exits.
The number of flight attendants required can be determined by the following formula:
The minimum number of flight attendants = (N / 50) + 1 where N is the number of passenger seats.
So, for an aircraft with 275 seats and 249 passengers:
(249 / 50) + 1
= 5 flight attendants are required.

What number must be an integer multiplied by to find a perfect square?
A number is a perfect square if the following property is satisfied:
a = b², where is a natural number.
Please notice that b can be either a prime number or a product of prime numbers.
Initially, we proceed to factorize 35280 by factorial decomposition, that is, as a product of prime numbers:
35280 = 2⁴ × 3² × 5 × 7²
35280 = (2²)² × 3² × 5 × 7²
35280 = 4² × 3² × 5 × 7²
Then, we must add a 5 to find a product that is a perfect square:

ou're buying a house that costs 300,000 with a down payment of \( 25 \% \) in cash and a 30 year mortgage for the rest at \( 2.75 \% \). What are your onthly principal + interest payments?
To calculate the monthly principal + interest payments for a house with a down payment and a mortgage using an Excel formula, you can use the PMT function. Here's how:
Calculate the loan amount by subtracting the down payment from the house cost. In this case, the down payment is 25% of $300,000, so it would be $75,000.
Loan Amount = $300,000 - $75,000 = $225,000
Determine the monthly interest rate by dividing the annual interest rate by 12. In this case, the annual interest rate is 2.75%, so the monthly interest rate would be 2.75% / 12 = 0.00229.
Determine the loan term in months. Since it's a 30-year mortgage, the loan term would be 30 * 12 = 360 months.
Use the PMT function in Excel to calculate the monthly principal + interest payment.
Monthly Payment = -PMT(0.00229, 360, 225000)
The negative sign is used because the payment is an outgoing cash flow.
By using this formula in Excel, you can find the monthly principal + interest payments for your mortgage. Remember to adjust the interest rate, loan amount, and loan term if they differ from the example provided.
To calculate the monthly principal + interest payments using an Excel formula, you can use the PMT function by inputting the appropriate parameters: the monthly interest rate, loan term in months, and loan amount.

determine whether or not the distribution is a discrete probability distribution and select the reason why or why not. x 3 5 6 p(x=x) 18 38 12
Yes, the given distribution is a discrete probability distribution.A discrete probability distribution is a distribution that assigns probabilities to distinct, separate outcomes.
In this case, the distribution lists specific values of the random variable x (3, 5, 6) along with their corresponding probabilities (18, 38, 12). Each probability corresponds to a particular value of x, and the values of x are discrete and distinct. Therefore, the distribution satisfies the requirements for a discrete probability distribution.
To further explain, a discrete probability distribution is characterized by three properties: the probabilities must be non-negative, the sum of all probabilities must equal 1, and each value of the random variable must have a corresponding probability.
In the given distribution, all probabilities are positive values (18, 38, 12), satisfying the first property. The sum of the probabilities is 18 + 38 + 12 = 68, which equals 1, satisfying the second property. Lastly, each value of x (3, 5, 6) has a corresponding probability, satisfying the third property.
Therefore, based on these properties, we can conclude that the given distribution is a discrete probability distribution.

how many six-digit strings have a digit sum of 35? note: in a digit string, the first digit can be zero.
The number of six-digit strings with a condition of digit sum of 35 is equal to 658,008.
To find the number of six-digit strings that have a digit sum of 35,
Use the concept of stars and bars.
Here, each digit in the string as a "star" and use "bars" to separate the digits and represent the sum.
Since the first digit can be zero, we will consider leading zeros as well.
Let's denote the six-digit string as A1A2A3A4A5A6, where each Ai represents a digit.
To represent the digit sum of 35,
Place 35 stars (representing the digits) and 5 bars (representing the separations) in a row.
The position of the bars determines how the digits are grouped.
For example, if we have the following arrangement: |||****||**, it represents the six-digit string 002035.
To count the number of arrangements,
Choose the positions of the 5 bars out of the 40 available positions (35 stars + 5 bars).
This can be calculated using combinations.
The number of arrangements is ,
C(40, 5) = 40! / (5! × (40 - 5)!)
Calculating this value,
C(40, 5)
= (40 × 39 × 38 × 37 × 36) / (5 × 4 × 3 × 2 × 1)
= 658,008
Therefore, there are 658,008 six-digit strings with a digit sum of 35.
