Is the function g(x)=(e^x)sinb an antiderivative of the function f(x)=(e^x)sinb

Answers

Answer 1

We can say that it is true that the function g(x)=(e^x)sinb is an antiderivative of the function f(x)=(e^x)sinb.

How did we arrive at the solution?

We can see here that to prove this, we need to show that g'(x) = f(x), where g'(x) is the derivative of g(x).

Using the product rule of differentiation, we have that:

g'(x) = (e^x)(cosb) + (sinb)(e^x).

A further simplification will give us:

g'(x) = (e^x)(cosb + sinb)

Thus, comparing g'(x) with f(x), we have: f(x) = (e^x)(sinb)

Therefore, comparing the two expressions, we can see that:

g'(x) = f(x) if and only if cosb + sinb = sinb.

This is true for all values of b, since:

cosb + sinb = sin(b + pi/4), and sin(b + pi/4) = sinb for all values of b.

We can then conclude that g(x) = (e^x)sinb is indeed an antiderivative of f(x) = (e^x)sinb.

Determine the perimeter of the right triangle shown.

right triangle with vertices at negative 5 comma 3, negative 5 comma negative 2, and 7 comma negative 2

Answers

The perimeter of the right triangle is 30 units.

What is perimeter?

In geometry, perimeter refers to the total length of the boundary of a two-dimensional shape, such as a polygon or a circle. It is the sum of the lengths of all the sides of the shape.

To find the perimeter of the right triangle, we need to determine the lengths of its sides first.

Using the distance formula, we can find the lengths of the three sides of the triangle:

Side 1: From (-5, 3) to (-5, -2)

[tex]Length = \sqrt{[(3 - (-2))^2 + (-5 - (-5))^2]} = \sqrt{[5^2]} = 5[/tex]

Side 2: From (-5, -2) to (7, -2)

[tex]Length = \sqrt{[(7 - (-5))^2 + (-2 - (-2))^2]} = \sqrt{[12^2]} = 12[/tex]

Side 3: From (7, -2) to (-5, 3)

[tex]Length = \sqrt{[(-5 - 7)^2 + (3 - (-2))^2]} = \sqrt{[144 + 25]} = \sqrt{[169]} = 13[/tex]

We know that the triangle is a right triangle because two of its sides (Side 2 and Side 3) form a straight line along the x-axis, and the third side (Side 1) is perpendicular to this line.

Therefore, Side 1 is the hypotenuse, and Sides 2 and 3 are the legs of the right triangle.

To find the perimeter, we add up the lengths of all three sides:

Perimeter = Side 1 + Side 2 + Side 3 = 5 + 12 + 13 = 30

Therefore, the perimeter of the right triangle is 30 units.

Find the value of x, y, and z in the rhombus below.
(-y-5)
(-27+8)
(-10x-8)
989

Answers

The diagonals of a rhombus are perpendicular bisectors of each other, so we can set up the following system of equations:
(-y-5) + (-27+8) = 0
(-10x-8) + 989 = 0
Solving for y and x, we get:
y = -10
x = -99.7
Since the diagonals of a rhombus bisect each other, we know that the length of each diagonal is half the length of the other diagonal. Let's call the length of the shorter diagonal z. Then we have:
z^2 = (-y-5)^2 + (-27+8)^2
z^2 = (-10)^2 + (19)^2
z^2 = 401
z = sqrt(401) = 20.03
So the value of z is approximately 20.03. hopper this helped i’m pretty sure that’s correct

The following headline refers to change. Identify the change as absolute or relative.


"Enrollments at Northeastern University are expected to increase by 1,700 students"

Answers

The change referred to in the headline is an absolute change. An absolute change is a difference or increase in a quantity that is measured without reference to the original or initial value.

In this case, the headline states that enrollments at Northeastern University are expected to increase by 1,700 students. This means that the actual number of students is expected to increase by 1,700 from its current or previous level, without any reference to the original number of students enrolled at Northeastern University.

An absolute change is usually expressed in units of the quantity being measured, such as students, dollars, or meters. In contrast, a relative change is expressed as a percentage or ratio of the original or initial value. A relative change indicates how much a quantity has changed in proportion to its initial value.

For example, if enrollments at Northeastern University were expected to increase by 10%, this would be a relative change because it represents a percentage of the current or previous level of enrollment. However, the headline specifies an absolute increase of 1,700 students, which does not depend on the current or previous level of enrollment.

How to calculate surface area of a cylinder?

In Mathematics and Geometry, the surface area (SA) of a cylinder can be calculated by using this mathematical equation (formula):

SA = 2πrh + 2πr²

Where:

h represents the height.r represents the radius.

From the circumference of the outside of the cylinder, the radius can be calculated as follows;

Circumference = 2πr

512.49 = 2(3.14)r

Radius, r = 512.49/6.28 = 81.61 yards.

By substituting the given parameters into the surface area of a cylinder formula, we have;

Surface area (SA) of cylinder = (2 × 3.14 × 81.61 × 7) + 2 × 3.14 × 81.61²

Find the derivative of y = ((2x - 1) ^ 3)//√(3x + 1)​

Answers

The derivative of the function y =  ((2x - 1)³)/√(3x + 1)​ is dy/dx = (2x - 1)²[3x + 6]/(2[√(3x + 1)]³)

What is the derivative of a function?

The derivative of a function is the limit as the change in x tnds to zero of the change in y over the change in x.

To find the derivative of the function y =  ((2x - 1)³)/√(3x + 1)​, we use the quotient rule.

dy/dx = (vdu/dx - udv/dx)/v²

where u = (2x - 1)³ and v = √(3x + 1)

So, du/dx = 3(2x - 1)² and dv/dx = 3/[2√(3x + 1)]

Substituting the values of the variables into the equation, we have that

dy/dx = (vdu/dx - udv/dx)/v²

dy/dx = (√(3x + 1) × 3(2x - 1)²  -  (2x - 1)³ × 3/[2√(3x + 1)])/[√(3x + 1)]²

dy/dx = (3√(3x + 1)(2x - 1)²  -  3(2x - 1)³/[2√(3x + 1)])/[√(3x + 1)]²

= (3√(3x + 1)√(3x + 1)(2x - 1)²  -  3(2x - 1)³/[2√(3x + 1)])(3x + 1)²

= [3(3x + 1)(2x - 1)²  -  3(2x - 1)³/[2√(3x + 1)])(3x + 1)²

= (2x - 1)²[3(3x + 1)  -  3(2x - 1)/[2√(3x + 1)])(3x + 1)²

Answers

The solution of Unit Problem is Solution of first part is As the contribution margin is positive, accepting the special sales order would be profitable for Hobby-Cardz,and second part is  total profit is negative

What is contribution margin ?

Contribution margin is the difference between a product's revenue and its variable costs. It represents the amount of money that is available to cover fixed costs and contribute to profit.

According to given information?

1)Incremental Analysis without special order:

Revenue from 51,000 packs at $0.43 per pack = $21,930

Total variable costs for 51,000 packs = 51,000 x $0.33 = $16,830

Contribution margin = $21,930 - $16,830 = $5,100

As the contribution margin is positive, accepting the special sales order would be profitable for Hobby-Cardz.

2)Incremental Analysis with special hologram baseball cards:

In addition to the incremental analysis performed in Part 1, we need to consider the additional cost of $5,300 to develop the hologram.

Revenue from 51,000 packs at $0.43 per pack = $21,930

Total variable costs for 51,000 packs = 51,000 x $0.33 = $16,830

Contribution margin = $21,930 - $16,830 = $5,100

Less: Additional cost of hologram development = $5,300

Total profit/loss = $5,100 - $5,300 = ($200)

As the total profit is negative, accepting the special sales order with the hologram development cost would result in a loss of $200. Therefore, Hobby-Cardz should not accept the special order under these circumstances.

What is exponential function  ?

The exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function.

Because the growth rate is inversely correlated with the function's present value, this function is exponential. Regardless of how many cells were present the previous hour the number of cells is multiplied by the same factor of 4 every hour.

Therefore, One can estimate the number of cells for every hour x by evaluating the function at a specific value of x. The function f(x) = 4x implies exponential growth.

Answers

The vertex of g(x) is translated left by 2 units and down by 5 units compared to the vertex of f(x).

The shape of the parabola for g(x) is the same as the shape of the parabola for f(x).

The minimum point of g(x) is lower than the minimum point of f(x).



The function g(x) is obtained from f(x) by the following sequence of transformations:

1. A horizontal shift left by 2 units (x + 2).
2. A vertical shift down by 5 units (-5).
3. A vertical stretch by a factor of 1 (the squared term does not change the stretch factor).
4. A reflection about the x-axis (the negative sign in front of the 5).

Myron's family is putting a pool in their backyard. He is so excited that he wants to figure out how
long it will take to fill the pool! He found the blueprints for the pool and recreated the sketches at
right, but he is not quite sure how to use them to find the volume of the pool.
What three-dimensional figures does Myron need to be able to find the volume of before he can
determine the volume of the pool?

Answers

To find the volume of an irregular 3D shape like Myron's pool, he needs to determine:

1. The length

2. The width

3. The depth

With those three measurements, he can plug them into the formula for volume of a rectangular prism:

Volume = Length x Width x Depth

So if the pool is:

Length = 20 ft

Width = 10 ft

Depth = 5 ft

Then the volume would be:

20 ft x 10 ft x 5 ft = 1000 cubic feet

Does this make sense? Let me know if Myron has any other questions!

The value of x in the given chords is determined as 9.

What is the measure of x?

The measure of length x is calculated by applying the following formula.

Based on the angle of intersecting chord theorem, we will have the following equation.

3 (3 + x ) = 4 ( 4 + 5 )

9 + 3x = 36

collect similar terms ang solve for x;

3x = 36 - 9

3x = 27

divide both sides of the equation by 3;

3x/3 = 27/3

x = 9

Thus, the value of x in the given chords is determined by applying chord theorem.

The correct frequency table is table c.

A plane moving at 450 miles per hour is flying in your direction. At one moment the angle formed between the ground and your line of sight to the plane is 45 degrees. One minute later the angle is 60 degrees. Find the altitude of the plane. Make sure to draw a complete diagram, show all calculations and explain your process.

Answers

The altitude of the plane is approximately 21.65 miles.

What is altitude means ?

An altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex).

We have an observer on the ground (you) and a plane flying towards you. Let's call the distance between the observer and the point directly below the plane "x", and let's call the altitude of the plane "h".

At the first moment, the angle between the ground and your line of sight to the plane is 45 degrees. This means that the angle between the plane's altitude and the ground is also 45 degrees (since the plane is flying horizontally towards you). We can use trigonometry to find the value of "x" in terms of "h".

In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:

tan(45) = h/x

Since tan(45) = 1, we can simplify this to:

h/x = 1

h = x

So the distance between the observer and the point directly below the plane is equal to the altitude of the plane.

One minute later, the angle between the ground and your line of sight to the plane is 60 degrees. We can use the same approach to find the new value of "x" in terms of "h".

In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:

tan(60) = h/(x + 450/60)

Simplifying this, we get:

h = (x + 7.5h) * sqrt(3)

Solving for "x", we get:

x = (h / sqrt(3)) - 7.5h

Now we can substitute the value of "x" from the first moment (which is equal to the altitude of the plane) into this equation to find the altitude of the plane:

h = (h / sqrt(3)) - 7.5h

h = h(1 / sqrt(3) - 7.5)

h = 21.65 miles (rounded to two decimal places)

Therefore, the altitude of the plane is approximately 21.65 miles.

According to the given information, the one angle on the straight line inside a circle is 135 then the value of the x = 4 as both angles are supplementary angles.

What are supplementary angles?

Supplementary angles are two angles whose sum is 180 degrees. In other words, if we add the measures of two supplementary angles, the result is always 180 degrees.

When two lines intersect, they form four angles at the intersection point. If two of these angles are supplementary, they are called adjacent supplementary angles. In this case, they share a common side and a common vertex, and their non-shared sides form a straight line.

For example, if angle A and angle B are adjacent angles, and angle A measures 120 degrees, then angle B must measure 60 degrees, since 120 + 60 = 180.

According to the given information

If the two angles are on a straight line, then they are supplementary, meaning their sum is 180 degrees. Therefore, we can set up the equation:

135 + (11x + 1) = 180

Simplifying the left side, we get:

136 + 11x = 180

Subtracting 136 from both sides, we get:

11x = 44

Dividing both sides by 11, we get:

x = 4

Therefore, the value of x is 4.
