The equation of the tangent line at (1,1) is given as follows:

y - 1 = -0.25(x - 1).

The curve for this problem is given as follows:

x² - y² = 2x + y + xy - 4.

Applying implicit differentiation, we obtain the slope of the tangent line, as follows:

2x - 2y(dy/dx) = 2 + (dy/dx) + x(dy/dx) + y

(dy/dx)(1 + x + 2y) = 2x - 2 - y

m = (2x - 2 - y)/(1 + x + 2y).

At x = 1 and y = 1, the slope is given as follows:

m = (2 - 2 - 1)/(1 + 1 + 2)

m = -0.25.

Hence the point-slope equation is given as follows:

The value of the expression is 1.766.

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.

Given the expression,

2\(e^{3x}\) = 400

divide by 2 into both sides

\(e^{3x}\) =  400/2

\(e^{3x}\) = 200

converting the expression in form of a log,

ln(\(e^{3x}\))= ln(200)

log(aⁿ) = n log(a)

3x ln(e) = ln(200)  [ln(e) = 1 and ln(200) = 5.2931]

3x = 5.2931

x = 1.766

Answer:

0.4 repeating as a fraction can be written as 4/9 in fractions.

Step-by-step explanation:

Let's understand the solution in detail.

Explanation:

0.4 repeating is a recurring fraction with infinite decimal places.

To convert it into fractions, we follow the below steps:

First, we can write:

x = 0.4 repeating = 0.444... (1)

Now, we multiply both sides by 10:

⇒ 10x = 4.444... (2)

Subtracting (1) from (2), we get:

⇒ 10x − x = 4.444... - 0.444...

We can now solve for x as follows:

⇒10x − x = (4 + 0.444...) − 0.444...

⇒ (10 − 1) x = 4 + 0

⇒ 9x = 4

⇒x = 4/9

Hence, 0.4 repeating can be written as 4/9 in fractions.

The number 0.4444... can be written as 4/9 in fractions.

The given number is,

x = 0.4 repeating

x = 0.444..   . (1)

Now, we multiply both sides by 10:

⇒ 10x = 4.444... (2)

Subtracting (1) from (2), we get:

⇒ 10x − x = 4.444... - 0.444...

We can now solve for x as follows:

⇒10x − x = (4 + 0.444...) − 0.444...

⇒ (10 − 1) x = 4 + 0

⇒ 9x = 4

Divide by 9 both side,

⇒x = 4/9

Therefore, 0.4 repeating can be written as 4/9 in fractions.

Standard form

\(y" + P(x)y'+Q(x) y =0\)

Hence your P(t) = -3, Q(t) = 2

\(y(x) = Vy_1(x)\rightarrow y'(x) = V'y_1(x) + Vy_1'(x) ~~~and ~~~y"(x) = v"y_1(x) +2V'y_1'(x)+Vy_1(x)\)

After replacing all y", y' and y to homogeneous part, you will have

\(e^x V"+5e^x V'=0\longleftrightarrow V"+5V'=0\) because \(e^x\ne 0\)

Let U = V'

\(U'+5U=0\rightarrow \frac{du}{u}=-5dx\) .

\(lnu= -5x \rightarrow u = e^{-5x}\)

Replace back,

\(V' = e^{-5x}\rightarrow V= \frac{e^{-5x}}{-5}\)

then

\(y(x) = V y_1(x) = \frac{e^{-4x}}{-5}\)

So, general solution of the ODE is

\(Ay_1(x) + By_2(x)\)

Particular solution is just take derivative of the general one twice and plug back into the original ODE to find A and B

Step-by-step explanation:

Step-by-step explanation:

we can easily count this, as the diagonal lines are squares truly in half. so, 2 such cut squares are in total 1 full square.

there is one central rectangle of 4×6 squares = 24.

then in the upper left corner there is a small 2×2 square = 4.

and then we have in the bottom left 2 and the bottom right also 2 small triangles (4 in total) with each having 1 full square and 2 half-squares (2 squares in total) as area.

so, 4×2 = 8 squares.

so, the whole area is

24 + 4 + 8 = 36

The area of the shaded region, with a frame of 3 units wide, is 264 square units. The inner rectangle is 6x4 units, and the outer rectangle is 18x16 units.

To solve the given problem, we have to find the area of the shaded region if the frame is 3 units wide. If the frame is 3 units wide, then the dimensions of the inner rectangle (the shaded region) will be (12 - 6) × (10 - 6) which simplifies to 6 × 4.

Therefore, we can say that the inner rectangle has a length of 6 units and a width of 4 units.The dimensions of the outer rectangle are (12 + 3 + 3) × (10 + 3 + 3) which simplifies to 18 × 16. Therefore, we can say that the outer rectangle has a length of 18 units and a width of 16 units.

The area of the shaded region can be obtained by subtracting the area of the inner rectangle from the area of the outer rectangle. Therefore, the Area of the outer rectangle = length × width= 18 × 16 = 288 square units

Area of the inner rectangle = length × width= 6 × 4 = 24 square units

Area of the shaded region = Area of the outer rectangle - Area of the inner rectangle = 288 - 24= 264 square units

Therefore, the area of the shaded region is 264 square units.

Given that we are aware that  triangle b = 9.00, A = 56, and B = 57, we can substitute the following numbers in the equation:

A/sin 56° = 9.00/sin 57°, and vice versa.

The Law of Sines, which states that the ratio between the length of each side of a triangle and the sine of the angle opposite that side is the same for all three sides, can be used to solve triangle ABC.

First, we may use the knowledge that the total of a triangle's angles equals 180 degrees to determine the size of angle C:

C = 180 A B = 180 - 56 A B = 57 A B = 67

The lengths of the remaining sides can then be determined using the Law of Sines:

A/Sin = B/Sin + C/Sin

Since we know that b = 9.00, A = 56, and B = 57, we can replace those values in the equation as follows:

9.00/sin 57° = a/sin 56°

Triangle ABC can be resolved by applying the Law of Sines, which states that the ratio between the length of each side of a triangle and the sine of the angle opposite that side is the same for all three sides.

First, we may calculate the amount of angle C using the fact that the sum of a triangle's angles is 180 degrees:

C = 180 A B = 180 - 56 A B = 57 A B = 67

The Law of Sines can then be used to calculate the lengths of the remaining sides:

Sin = Sin + Sin + Sin

Given that we are aware that b = 9.00, A = 56, and B = 57, we can substitute the following numbers in the equation:

A/sin 56° = 9.00/sin 57°, and vice versa.

z/xy  where z units squared is the total area of the two outside walls and xy is the area of one sheet.

Step-by-step explanation:

First find the area of a single sheet as;

Length of the sheet is x units

Assume the width of the sheet to be y units

The area of the sheet will be : x* y = xy units squared.

Second, find the total area of the two outside corners walls of the bedroom.

Lets say the total area of the two outside walls is z units squared.

Then to get number of sheets of dry wall you need for the two outside walls of the bedroom will be;

= Total area of the two outside walls / The area of  one sheet

= z/xy

Use real values for x, y and z to find the actual number of sheets required for the two outside corners walls of the bedroom.
