Using implicit differentiation the second derivative is d²y/dx² = [-2x³y² × dy/dx  + 2y³x²]/y⁶

Since we have the function x⁴ + y⁴ = 16, we desire to find the second derivative by implicit differentiation. We proceed as follows.

Since  

x⁴ + y⁴ = 16

Taking the first derivative of the function, we have that

d(x⁴ + y⁴)/dx = d16/dx

dx⁴/dx + dy⁴/dx = d16/dx

4x³ + 4y³ × dy/dx = 0

4y³ × dy/dx = -4x³

dy/dx =  -4x³/4y³

dy/dx = -x³/y³

We now differentiate again to take the second derivative of the function. So, we have that

dy/dx = -x³/y³

Using the quotient rule, we have dy/dx = (udv/dx - vdu/dx)/v² where u = -x³ and v = y³.

So, substituting this into the equation, we have that

d(dy/dx)/dx = (-x³dy³/dx - y³d-x³/dx)/(y³)²

= [-x³dy³/dy × dy/dx  - y³d(-x³/dx)]/(y³)²

= [-x³2y² × dy/dx  + y³2x²]/(y³)²

d²y/dx² = [-2x³y² × dy/dx  + 2y³x²]/y⁶

The second derivative is d²y/dx² = [-2x³y² × dy/dx  + 2y³x²]/y⁶

Answer:

Hello there! I believe b or d

The expansion will be 64d^6 + 1152d^5 + 9720d^4 + 43740d^3 + 98415d^2 + 145458d + 729

We can expand (2d+3)^6 using the binomial theorem, which states that:

(a + b)^n = nC0 * a^n * b^0 + nC1 * a^(n-1) * b^1 + nC2 * a^(n-2) * b^2 + ... + nCn-1 * a^1 * b^(n-1) + nCn * a^0 * b^n

where nCk is the binomial coefficient, given by:

nCk = n! / (k! * (n-k)!)

Expanding (2d+3)^6 using this formula, we get:

(2d+3)^6 = 6C0 * (2d)^6 * 3^0 + 6C1 * (2d)^5 * 3^1 + 6C2 * (2d)^4 * 3^2 + 6C3 * (2d)^3 * 3^3 + 6C4 * (2d)^2 * 3^4 + 6C5 * (2d)^1 * 3^5 + 6C6 * (2d)^0 * 3^6

Simplifying each term using the binomial coefficient formula, we get:

(2d+3)^6 = 1 * 64d^6 * 1 + 6 * 32d^5 * 3 + 15 * 16d^4 * 9 + 20 * 8d^3 * 27 + 15 * 4d^2 * 81 + 6 * 2d * 243 + 1 * 1 * 729

Simplifying each term further, we get:

(2d+3)^6 = 64d^6 + 1152d^5 + 9720d^4 + 43740d^3 + 98415d^2 + 145458d + 729

Answer:

Rate: 56.25 mi/h

Distance traveled in 3 hours: 168.75 mi

Explanation:

We know that 1 mile is equal to 1.6 kilometers, so, we can change the rate of 90 kilometers per hour to miles per hour as:

Now, we know that every hour the car travel 56.25 miles, so, the number of miles that the car travel after 3 hours is:

Therefore, the answers are:

Rate: 56.25 mi/h

Distance traveled in 3 hours: 168.75 mi

The limit of xlnx when x is tending towards zero is zero.

What is limit in mathematics?

In mathematics, a limit is the value that a function (or sequence) approaches as the input (or index) approaches a particular value. Without limits, it is impossible to perform calculus or mathematical analysis; limits are also necessary to compute continuity, derivatives, and integrals.

Given limit is:

\(\lim_{x \to 0} x lnX\)

Considering f = x, and g = ln x

The limit of f and g are both zero or both ±∞, and the limit f′/g′ exists, then the limit f/g equals it.

The wrong in the expression x lnx is we are individually defining f and g doesn't meet the hypothesis. so, we write it as

\(\frac{lnx}{1/x}\)

We now use L' Hospital rule with f(x) = lnx, g(x) = 1/x as

The limits

\(\lim_{x \to 0^+} lnx= - \infty\), and

\(\lim_{x \to 0^+} \frac{1}{x}\)

The limits  \(\lim_{x \to 0^+} \frac{f'(x)}{g'(x)}\) exists as:

\(\lim_{x \to 0^+} \frac{1/x}{-1/x^2} = \lim_{x \to 0^+} -x = 0\)

Hence the answer is 0.

Step-by-step explanation:

Answer:

Perimeter:\(4x+10\) feet
Area:\(x^{2}+5x+6\) feet

Step-by-step explanation:

The perimeter is equal to 2*width +2*length. The width is x+2 and the length is x+3, therefore the perimeter is equal to 2x+4+2x+6 which equals 4x+10.
The area is equal to width*length

You have to multiply to get a simple equation so it would be 15x+45=15x-2x+10 and that’s where my knowledge stops with that

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Let's solve your equation step-by-step.

5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )

Step 1: Simplify both sides of the equation.

5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )

( 5 ) ( 3x ) + ( 5 ) ( 9 ) + −2x = 15x + ( −2 ) ( x ) + ( −2 ) ( −5 ) ( Distribute )

15x + 45 + −2x = 15x + −2x + 10

( 15x + −2x ) + ( 45 ) = ( 15x + −2x ) + ( 10 ) ( Combine Like Terms )

13x + 45 = 13x + 10

13x + 45 = 13x + 10

Step 2: Subtract 13x from both sides.

13x + 45 − 1 3x = 13x + 10 − 13x

45 = 10

Step 3: Subtract 45 from both sides.

45 − 45 = 10 − 45

0 = −35

Answer:

1 quarter, 2 dimes, 1 nickel, and 3 pennies can be used to make 82 cents.

Step-by-step explanation:

One possible set of 7 coins that make 82 cents is:

1 quarter (25 cents)

2 dimes (10 cents each)

1 nickel (5 cents)

3 pennies (1 cent each)

Adding up the values of these coins:

25 + 10 + 10 + 5 + 1 + 1 + 1 = 82

Therefore, a set of 1 quarter, 2 dimes, 1 nickel, and 3 pennies can be used to make 82 cents.

The probability Julian chooses a blue hat is 1/3.

Probability refers to the branch of math which deals with finding out the likelihood of the occurrence of an event.

Total hat is:

= 150.

There are a total of 150 hats to choose from.

The number of blue hats to choose from is:

= 40 + 10

The order of the graphs from largest to lowest correlation coefficients is:

The correlation coefficient between two variables is a coefficient that tells us "how much" these variables relate.

So, in the case for linear correlation, as "more linear" the data appears to be, a large correlation is between the two variables.

With that in mind, we conclude that the order of the graphs (going for larger correlation coefficient to smaller correlation coefficient) is:
