Answer: E

Step-by-step explanation:

The derivative of the given function sin(xy)=3x−2y is obtained as;

dy/dx =  3sec(xy)/x - y/x

The given equation is-

sin(xy) = 3x − 2y

Be sure to account for both sides of this argument.

d/dx(sin(xy)) = d/dx(3x − 2y)

Differentiate the equation's left side.

Set the left side equal to a right side to reform the equation.

x.cos(xy).y' + y.cos(xy) = 3

Solve for y'.

y' = 3sec(xy)/x - y/x

Thus, replace y' with dy/dx

dy/dx =  3sec(xy)/x - y/x

Thus, the derivative of the given function sin(x y)=3x−2y is obtained as;

dy/dx =  3sec(xy)/x - y/x

The value of  [tex]\sqrt{0.9}[/tex] is 0.94868329805. You can't get an accurate answer since the square root is an irrational quantity. But I suppose you could just make it simpler.

The value that a number produces when it is multiplied by itself is known as the square root of the number. The square root is denoted by the radical sign. For instance, 16 Equals 4. The root symbol or surds is another name for the radical symbol.

The radical symbol for the number's root is "" in this instance. The square of the positive number is represented by multiplying it by itself. The original number is obtained by taking the square root of the square of a positive number. For instance, the square of three is nine. and the square root of 9, √9 = 3.

Since, 3*3*0.1

Step-by-step explanation:

Experimental probability is based on the actual results of an experiment (gathered by experimenting repeatedly).  

It is calculated by dividing the recorded number of times an event happens by the total number of trials in the actual experiment:

[tex]\boxed{\textsf{Experimental Probability} = \dfrac{\textsf{Number of times an event happens}}{\textsf{Total number of trials}}}[/tex]

As the number of trials increases, we would expect for the experimental probability to get closer to the theoretical probability.

Given:

The experimental probability of drawing a short straw is:

[tex]\implies \sf P(short\;straw)=\dfrac{35}{50}=\dfrac{7}{10}[/tex]

If Laura conducts 10 further trials of the experiment, based on the results in the table, the number of additional trials that will have a result of a short straw being drawn is:

D. y = 5x - 15. y = 5(x - 3) has Infinitely many solutions.

Graphical solutions of a system of equations are a way of finding the intersection points of all the equations given.

We are given graph each system of equations, If they intersect at one point they have one solution, if they are parallel to each other they have no solution and if they are coinciding with each other they have infinitely many solutions.

y = - (4/3)x + 4.

y = - (4/3)x - 1.

These are parallel lines no solution thus we have;

y = 4x - 5.

y = - 2x + 7.

These lines intersect at (2, 3) one solution thus we have;

2x + 3y = 8

4x + 6y = 17.

They are parallel to each other thus we have;

y = 5x - 15.

y = 5(x - 3).

The length AC of the triangle ABC is approximately 12.083 centimeters.

The law of sine is a relationship between the sides and the angles of the triangle, which is defined below:

AB / sin C = AC / sin B = BC / sin A

Where:

First, determine the measure of angle C:

AB / sin C = BC / sin A

sin C = (AB / BC) · sin A

sin C = (8.2 / 13.5) · sin 81°

C ≈ 36.865°

Second, determine the measure of angle B:

B = 180° - A - C

B = 180° - 81° - 36.865°

B = 62.135°

Third, determine the length of side AC:

AC / sin B = BC / sin A

AC = BC · (sin B / sin A)

AC = 13.5 · (sin 62.135° / sin 81°)

The value of sin (x - y) of the triangles is -33/65

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles

Given: sin x = 3/5 and cos y = 5/13.  Both triangles are in quadrant 1

(Consider the image attached)

For triangle with angle x

adjacent = √(5²-3²)  = 4

cos x = 4/5 (adjacent/hypotenuse)

For triangle with angle y

opposite = √(13²-5²)  = 12

sin y = 12/13 (opposite/hypotenuse)

Using the trigonometric identity:

sin(x-y) = sinxcosy - sinycosx

sin(x-y) = (3/5)×(5/13) - (12/13)×(4/5)

sin(x-y) = 3/13 - 48/65

The four equations' coefficients of x can only take two values, thus if one of those values is m, the other solution will be -1/m.

A relation between different terms on either side of the equal sign is described by a straightforward equation.

Simple equations also follow one or a mixture of the four arithmetic computations of addition, simple arithmetic, multiplication, and division.

There are three primary versions of the set of equations: point-slope form, standard form, or slope-intercept form.

So, Shannon's error would be:

In a rectangle, the adjoining sides are perpendicular to one other, whereas parallel runs between the opposing sides.

The slope of parallel lines is equal, and the slope, of a line perpendicular to some other line with a slope, m, is -1/m , thus the slopes of the central axis should be equal, which also gives:

Two sets of systems of equations with equal slopes should make up the equation: B. Y = -x + 6 and Y = -x - 5 are a pair.

Therefore, the slopes of the other two lines are -1/-1 = 1 and the equations of the other two lines are y = x - 4 and y = x - 5 correspondingly.

Therefore, the four equations' coefficients of x can only take two values, thus if one of those values is m, the other solution will be -1/m.

Answer:

(4) (-1,6)

Step-by-step explanation:

f(x) = x² - 3x + 4

1) (0,4) ==>x=0 and f(x)=4

4 = 0² - 3(0) + 4

4 = 0 + 4

4 = 4 ==> true X

2) (1.5,1.75)==> x=1.5 and f(x)=1.75

1.75 = (1.5)² - 3(1.5) + 4

1.75 = 2.25 - 4.5 + 4

1.75 = 2.25 - 0.5

1.75 = 1.75 ==> true  X

3) (5,14)

14 = (5)² - 3(5) + 4

14 = 25 - 15 + 4

14 = 10 + 4

14 = 14  ==> true X

4) (-1,6)

6 = (-1)² - 3(-1) + 4

6 = (|-1|)² - (-3) + 4  ==> the square of a negative number is equal to the square

                              of the absolute value of that number since the square of

                             a real number is always positive

6 = (1)²+ 3 + 4  ==> subtracting a negative number is equivalent to adding

                          the positive number

6 = 1 + 3 + 4

6 = 4 + 4

6 = 8  ==> false √√

The random variable x's mean and standard deviation are 8 and 2, respectively. W=7+ 4x is the formula for the random variable w. The mean of w is E(W) =39

A dataset's mean is calculated by dividing the sum of all values by the total number of values. The term "average" is frequently used to describe it because it is the most widely used central tendency metric.

Divide the entire number of values by the total number of numbers to find the average. A mean is the term used to describe the mathematical average of a set of two or more data values. Average is also referred to as mean or arithmetic mean.

The mean is the average value of the data. It's easy to calculate: just add up all the numbers, then divide by the total number of numbers. Or, to put it another way, it is equal to the sum divided by the quantity.

The mean is then determined as follows:

E(W) = E (7 + 4X)

This results

E(W) = 7 + 4 E (X)

We thus have:

E(W) = 7 + 4 x 8

E(W) =39

Standard deviation = 8 and mean = 39.

What is standard deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.

Given, the formula for mean is E(W) = 7 + 4(X)

∴ E(W) = 7 + 4E(X)

Mean, E(X) equals to 8, hence substituting in the above equation, we get,

E(W) = 7 + 4×8

⇒E(W) = 39

Since, E(W) = 7 + 4(X)

Var(W) = Var(7) + Var(4X)

Since, Var(constant)=0,

Var(W) = Var(4X)

Var(W) = 4²×Var(X), where Var(X)=σₓ²

⇒ Var(W) = 16×σₓ², where σₓ²=2²

⇒ Var(W) = 16×4

⇒ Var(W) = 64

Standard Deviation (SD) = √64 = 8

Thus, standard deviation = 8 and mean = 39.

The vertices for the right triangle in this problem are given as follows:

(-4, -1), (2,1), (2,6).

Hence the base of the triangle is of:

[tex]B = \sqrt{(2 - (-4))^2 + (1 - (-1))^2} = 6.3[/tex]

The height is given as follows:

6 - 1 = 5.

Which means that the area of the triangle is of:

Area = 0.5 x 5 x 6.3 = 15.75.
