The value of k for the given differential equation is exact is,

⇒ k = 12

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The given differential equation is,

⇒ (y³ + kxy⁴ - 2x) dx + (3xy² + 24x²y³) dy = 0

And, The given differential equation is exact.

Now, We know that;

For the differential equation M dx + N dy = 0;

The condition of exactness is,

⇒ dM / dy = dN / dx  .. (i)

Here, We have;

M = y³ + kxy⁴ - 2x

N = 3xy² + 24x²y³

Hence, We get;

M = y³ + kxy⁴ - 2x

dM / dy = 3y² + 4kxy³

N = 3xy² + 24x²y³

dN / dx = 3y² + 48xy³

From (i);

⇒ dM / dy = dN / dx

⇒ 3y² + 4kxy³ = 3y² + 48xy³

⇒ 4kxy³ = 48xy³

⇒ 4k = 48

⇒ k = 48/4

⇒ k = 12

Thus, The value of k = 12

Answer:

yellow bar

Step-by-step explanation:

The given Mayan number which is : :|| :|| in decimal (base 10) is 42.

The Mayan number system is a base-20 system that uses three symbols: a dot (.), a horizontal bar (|), and a shell-like symbol (:). The symbol for zero is a shell-like symbol (:).

To convert the given Mayan number to decimal (base 10), we need to understand the positional value of each symbol. Each position in the number represents a power of 20, with the rightmost position being 20⁰, the next position to the left being 20¹, and so on.

The Mayan number given, : :|| :||, can be broken down as follows:

The leftmost position has no symbol, which represents a value of 0.

The second position from the left has two shell-like symbols (:), which represents a value of 2x20¹ = 40.

The third position from the left has two horizontal bars (||), which represents a value of 2x20⁰ = 2.

The given Mayan number in decimal (base 10) is 40 + 2 = 42.

Answer:

Gabriella will make $61 more than Mila after 5 years

Step-by-step explanation:

Gabriella Data

Principal Amount P= $73,000

Rate r = 3% or 0.03

Compounded continuously

Time t = 5 years

The formula used is: \(A=Pe^{rt}\)

Putting values and finding A

\(A=Pe^{rt}\\A=73000e^{0.03*5}\\A=73000e^{015}\\A=84813.899\\A\approx84814\)

So, After 5 years Gabriella will have $84814

Mila Data:

Principal Amount P= $73,000

Rate r = 3% or 0.03

Compounded quarterly n = 4

Time t = 5 years

The formula used is:\(A=P(1+\frac{r}{n})^{nt}\)

Putting values and finding A

\(A=P(1+\frac{r}{n})^{nt}\\A=73000(1+\frac{0.03}{4})^{4*5}\\A= 73000(1+0.0075)^{20}\\A= 73000(1.0075)^{20}\\A=73000(1.161)\\A=84753\)

So, After 5 years Mila will have $84753

Now subtracting to find the difference 84814-84753 = 61

So, Gabriella will make $61 more than Mila after 5 years

The length of each side of the wood is 5 centimetres.

Doug has 8 square pieces of wood. Each piece of wood have a side length of s cm. The total area of all 8 pieces of wood is 200 cm².

Hence, using quadratic equation let's find the length of each side of the wood.

Therefore,

8s² = 200

Hence,

8s² = 200

divide both sides of the equation by 8

s² = 200 / 8

s² = 25

s = √25

s = 5 centimetres

If two triangles are similar, then their internal angles have the same measure.

Since the internal angles of any triangle must sum to 180º, then the angle R must have a measure of 50º and the angle A must have a measure of 50º.

Nevertheless, notice that angles C and B have a measure of 65º while the angles S and T have measures of 67º and 63º respectively.

Since not all the angles from triangle ABC match those of STR, then, these triangles are not similar.

Answer:

The answer is "1035.76 miles"

Explanation:

The aircraft flies at 120 mph for 1.5 hours at a \(10^{\circ}\) bearing, then flies at the very same speed at \(100^{\circ}\) bearings for 8.5 hours.

However an angle of \(100-10 = 90^{\circ}\) between displacements

First shifts\(= 1.5 \times 120 = 180\ miles.\)

Second shift \(= 8.5\times 120 = 1020\ miles.\)

These two shifts are at \(90^{\circ}\) and therefore the final shift is:

\(\to \sqrt{180^2+1020^2}=1035.76 \ miles\)

The equation of remaining chocolate C  in terms of t is C = 30 - 3t.

A mathematical statement called an equation demonstrates the balance or equality of two expressions. It contains of variables, integers, and mathematical operations and is denoted by the equal symbol (=). Equations may be solved to determine unknown values and are used to express relationships between various quantities. To solve for x in the equation 2x + 3 = 7, for instance, remove 3 from both sides, which gives 2x = 4, then divide both sides by 2, which gives x = 2.

Given that,

Initial number of chocolates in box = 30

Also given that after 8 nights, number of remaining chocolates = 6

Implies that,

In 8 nights, 24 chocolates were treated.

In 1 night, 3 chocolates were treated.

The numerical value of x in angle ABD is 9 as angle ABC is divided into two equal halves.

An angle bisector divided an angle into two equal halves.

From the diagram:

Line BD divides angle ABC into two equal halves.

Angle ABD = ( 3x - 7 ) degrees

Angle DBC = 20 degrees

Since angle ABD and DBC are equal haves;

Angle ABD = Angle DBC

Plug in the values:

( 3x - 7 ) = 20

Solve for x:

3x - 7 = 20

Add 7 to both sides:

3x - 7 + 7 = 20 + 7

3x = 27

x = 27/3

x = 9

Therefore, the value of x is 9.

The  answer of this queation :∫ (4 + √x + x/x) dx = 4x + 2/3 x^(3/2) + x + C

where C = C1 + C2 + C3 is the constant of integration for the entire expression.

eparate integrals:

∫ 4 dx + ∫√x dx + ∫ x/x dx

The first two integrals can be easily integrated as follows:

∫ 4 dx = 4x + C1, where C1 is a constant of integration.

∫√x dx = 2/3 x^(3/2) + C2, where C2 is a constant of integration.

For the third integral, note that x/x simplifies to 1 for all nonzero x.

∫ x/x dx = ∫ 1 dx = x + C3, where C3 is a constant of integration.

Putting it all together, we have:

∫ (4 + √x + x/x) dx = 4x + 2/3 x^(3/2) + x + C
