Question 5 Use the rules of differentiation to find the derivative of the function y (6x + 1)5 + 30x(6x + 1)ª (6x + 1)² (36x + 1) 1 X 6 No correct answer provided. = X x(6x + 1)5.
The derivative of the function y = x(6x + 1)⁵ is: dy/dx = (6x + 1)⁵ + 30x(6x + 1)⁴
To find the derivative of the given function, we can apply the rules of differentiation. Using the product rule, we differentiate each term separately and then add them together.
For the first term x, the derivative is simply 1.
For the second term (6x + 1)⁵, we apply the chain rule. The derivative of (6x + 1)⁵ with respect to x is 5(6x + 1)⁴ multiplied by the derivative of the inner function 6x + 1, which is 6.
Multiplying these derivatives together, we get (6x + 1)⁵ * 6 = 6(6x + 1)⁵.
For the third term x(6x + 1)⁴, we again apply the product rule. The derivative of x is 1, and the derivative of (6x + 1)⁴ is 4(6x + 1)³ multiplied by the derivative of the inner function 6x + 1, which is 6.
Multiplying these derivatives together, we get x * 4(6x + 1)³ * 6 = 24x(6x + 1)³.
Finally, we add the derivatives of each term to get the derivative of the entire function: dy/dx = (6x + 1)⁵ + 30x(6x + 1)⁴.

If a loan is taken out for $278 at 10% and costs the borrower $174.12 in simple interest, how many years was the loan for? ROUND YOUR ANSWER TO THE NEAREST WHOLE YEAR
Data:
Loan=$278 at 10%
A simple interest is calculated for payments on the initial capital.
If the total interest was $174.12.
If the interest is on a year. You calculated the interes of one year. The 10% of $278:
\(278\cdot\frac{10}{100}=27.8\)In a year the interest is $27.8.
Then, $174.12 divided into $27.8 is the number of years of the loan:
\(\frac{174.12}{27.8}=6.26\approx6\)Then, the loan was for 6 yearsThe Transportation Security Administration (TSA) is responsible for airport security. On some flights, TSA officers randomly select passengers for an extra security check before boarding. One such flight has 76 passengers (12 in first class and 64 in coach). TSA officers selected an SRS of 10 passengers for screening. Let p-hat be the proportion of first class passengers in this sample. So, assuming that you are checking for the probability of choosing a first class passenger out of all passengers on the flight. Is the 10% condition met in this case? Justify your answer. (POS 447#31)
- Yes, 10 passengers out of 76 is less than 10% of the population of the flight.
- yes, 10 passengers out of all passengers on all flights is less than 10% of the population
- No, 10 passengers is the population being studied and is not less than 10% of the 10 total
- No, 10 passengers out of 76 is more than 10% of the population of the flight.

Answer:
CD = 16
Step-by-step explanation:
Segments EF and EC are tangent and secant respectively to the circle drawn from external point E.
Thus, by tangent-secant theorem:
\(ED\times EC= EF^2\)
\(\implies x(x+x+7)= (15)^2\)
\(\implies 2x^2+7x= 225\)
\(\implies 2x^2+7x-225=0\)
Comparing above quadratic equation with \(ax^2+bx+c=0\), we find:
a = 2, b = 7, c = -225
Now, we find the value of the discriminant
\(\implies b^2-4ac= (7)^2-4(2)(-225)= 1849\)
Now, by quadratic formula:
\(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)
\(\implies x=\frac{-7\pm\sqrt{1849}}{2(2)}\)
\(\implies x=\frac{-7\pm (43)}{4}\)
\(\implies x=\frac{-7+ 43}{4}\: or\:x=\frac{-7- 43}{4} \)
\(\implies x=\frac{36}{4}\: or\:x=\frac{- 50}{4} \)
\(\implies x=9\: or\:x=-12.5 \)
x represents length, so it can't be negative.
\(\implies x\neq -12.5\)
\(\implies x=9\)

Determine Whether The Given Function Is A Solution Of The Differential Equation. Y = X; Xy' - Y = 0 a. Yes b. No
Therefore, the answer is:
a. Yes
How to find that the Given Function Is A Solution Of The Differential Equation?To determine whether the given function y = x is a solution of the differential equation \(xy' - y = 0,\) we need to substitute \(y = x\) and \(y' = 1\) into the differential equation and check whether the equation is satisfied.
Substituting \(y = x\) and \(y' = 1\), we get:
x(1) - x = 0
Simplifying the equation, we get:
0 = 0
Since this equation is true regardless of the value of x, we can conclude that y = x is indeed a solution of the differential equation \(xy' - y = 0\).
Therefore, the answer is:
a. Yes

B. x - 2 <= 4 && x - 2 > -4
C. x - 2 <= 4 && x - 2 >= -4
D. x - 2 <= 4 || x - 2 >= -4
Answer:
A is the answer
the test of the options are not the answer
Given |x - 2| <= 4, which of the following equation is C. x - 2 <= 4 && x - 2 >= -4.
The absolute value of (x - 2) represents the distance between x and 2 on the number line. The inequality |x - 2| <= 4 means that the distance between x and 2 is less than or equal to 4.
To solve for x, we can break it down into two inequalities:
1. x - 2 <= 4, which means x <= 6
2. -(x - 2) <= 4, which means -x + 2 <= 4, then -x <= 2, then x >= -2
Combining these two inequalities, we get:
x - 2 <= 4 && x - 2 >= -4
Therefore, the correct answer is C.
When solving an inequality involving absolute value, it's helpful to break it down into two separate inequalities and then combine them. In this case, we found that the correct answer is C.

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 21. 521. 5 pounds and a standard deviation of 4. 94. 9 pounds. Step 2 of 2 : if a sampling distribution is created using samples of the amounts of weight lost by 8282 people on this diet, what would be the standard deviation of the sampling distribution of sample means? round to two decimal places, if necessary
The standard deviation of the sampling distribution of sample means is 0.054 pounds.
Now, let's consider the standard deviation of the sampling distribution of sample means. This is a measure of how much the means of different samples of the same size vary from each other. It is also referred to as the standard error of the mean (SEM). The formula for calculating the SEM is:
SEM = standard deviation of population / square root of sample size
In this case, the population is all people on this diet, and the standard deviation of the population is given as 4.9 pounds. The sample size is 8282 people. Therefore, we can calculate the SEM as:
SEM = 4.9 / square root of 8282
= 0.054 pounds
This means that the means of different samples of 8282 people on this diet are expected to deviate from each other by an average of 0.054 pounds.

Which of the following represents the rectangular equation x2 + y2 − 2x + 8y = 0 in polar form?
a. r = −2sin θ + 8cos θ
b. r = 2sin θ − 8cos θ
c. r = −8sin θ + 2cos θ
d. r = 8sin θ − 2cos θ
The rectangular equation x² + y² - 2x + 8y = 0 can be represented in polar form as r = 8sin(θ) - 2cos(θ). d.
To convert the given equation x² + y² - 2x + 8y = 0 from rectangular form to polar form, we'll use the following conversions:
x = r cos(θ)
y = r sin(θ)
Let's substitute these values into the equation and simplify:
(x² + y²) - 2x + 8y = 0
[(r cos(θ))² + (r sin(θ))²] - 2(r cos(θ)) + 8(r sin(θ)) = 0
[r² cos²(θ) + r² sin²(θ)] - 2r cos(θ) + 8r sin(θ) = 0
r² (cos²(θ) + sin²(θ)) - 2r cos(θ) + 8r sin(θ) = 0
r² - 2r cos(θ) + 8r sin(θ) = 0
Now the equation is in polar form, r² - 2r cos(θ) + 8r sin(θ) = 0.
Comparing this equation with the given options, we can see that the correct answer is:
r = 8sin(θ) - 2cos(θ)

Find dz/dt, for the following:
z(x,y)=xy^2 + x^2y, x(t)=at^2 , y(t) = 2at
dz/dt for the given functions is \(16a^3t^3 + 10a^3t^4\).
To find dz/dt for z(x, y) = \(xy^2 + x^2y\), x(t) = at^2, and y(t) = 2at, we'll use the chain rule.
Here's a step-by-step explanation:
Step 1: Find the partial derivatives of z with respect to x and y. \(∂z/∂x = y^2 + 2xy ∂z/∂y = 2xy + x^2\)
Step 2: Find the derivatives of x(t) and y(t) with respect to t. dx/dt = 2at dy/dt = 2a
Step 3: Apply the chain rule to find dz/dt. dz/dt = (∂z/∂x)(dx/dt) + (∂z/∂y)(dy/dt)
Step 4: Substitute the expressions from steps 1 and 2 into the chain rule equation. dz/dt = \((y^2 + 2xy)(2at) + (2xy + x^2)(2a)\)
Step 5: Replace x and y with their expressions in terms of t: x = at^2 and y = 2at. dz/dt = \(((2at)^2 + 2(at^2)(2at))(2at) + (2(at^2)(2at) + (at^2)^2)(2a)\)
Step 6: Simplify the expression.
dz/dt = \((4a^2t^2 + 4a^2t^3)(2at) + (4a^2t^3 + a^4t^4)(2a)\)
dz/dt = \(8a^3t^3 + 8a^3t^4 + 8a^3t^3 + 2a^5t^4\)
dz/dt = \(16a^3t^3 + 10a^3t^4\)
So, dz/dt for the given functions is \(16a^3t^3 + 10a^3t^4.\)
