A ball rolls down a hill. It starts with velocity of 2 m/s After 2 seconds, the ball has a velocity of 12 m/s What is the acceleration of the ball? ​

Answers

Answer 1

The acceleration of the ball is 5 ms2.

What is acceleration?

Acceleration is the rate at which an object's velocity with respect to time changes. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration.

The acceleration of the car in its present direction of motion is referred to as a linear acceleration (or tangential acceleration in circular motions), and the passengers on board feel a force pressing them back into their seats as a result.

The acceleration that is used to change direction is referred to as radial acceleration (or centripetal acceleration in circular travels), and the reaction that the passengers feel is a centrifugal force.

Therefore, The acceleration of the ball is 5 ms2.

Answers

The probability that in 5 flips, at least 3 tails will come will be 0.36.

What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Given is that you flipped a weighted coin that comes up heads 40% of the time and tails 60%.

The coin shows up heads 40% of the time and tails 60%, this means that the probability of turning to tails would be 0.6 . For 5 flips that, the probability that at least 3 tails will come will be -

P{A} = (0.6 + 0.6 + 0.6)/5 = 1.8/5 = 0.36

P{A} = 0.36

Therefore, the probability that in 5 flips, at least 3 tails will come will be 0.36

two-point and three-point shots did the Cruisers score?

Answers

The number of two-points and three points shot the cruisers scored are 24 and 19 respectively.

How to find the number of two and three points made?

The Cruisers scored a total of 105 points in a basketball game against the Strikers. The Cruisers had a total of 43 baskets, some of which were two-point shots and some of which were three-point shots.

Therefore, the number of two-points and three-points the cruiser scored is as follows:

let

x = number of two-points

y = number of three-points

Hence, using equation

x + y = 43

2x + 3y = 105

Multiply equation(i) by 2

2x + 2y = 86

2x + 3y = 105

subtract equation(i) from equation(ii)

y = 19

Let's find x as follows:

x = 43 - 19

x = 24

Therefore,

number of two points = 24

number of three points = 19

How do I solve this problem?

5 + 2/3 ( 2p - 6 ) = 9

Answers

Answer:

p = 6

Step-by-step explanation:

5 + 2/3 (2p - 6) = 9

5 + 4/3p - 4 = 9

1 + 4/3p = 9

4/3p = 8

p = 6

Answer:

p= 6

Step-by-step explanation:

Solve for p:

(2 (2 p - 6))/3 + 5 = 9

Put each term in (2 (2 p - 6))/3 + 5 over the common denominator 3: (2 (2 p - 6))/3 + 5 = 15/3 + (2 (2 p - 6))/3:

(15/3 + (2 (2 p - 6))/3) = 9

15/3 + (2 (2 p - 6))/3 = (2 (2 p - 6) + 15)/3:

((2 (2 p - 6) + 15)/3) = 9

2 (2 p - 6) = 4 p - 12:

((4 p - 12) + 15)/3 = 9

Grouping like terms, 4 p - 12 + 15 = 4 p + (15 - 12):

(4 p + (15 - 12))/3 = 9

15 - 12 = 3:

(4 p + 3)/3 = 9

Multiply both sides of (4 p + 3)/3 = 9 by 3:

(3 (4 p + 3))/3 = 3×9

(3 (4 p + 3))/3 = 3/3×(4 p + 3) = 4 p + 3:

(4 p + 3) = 3×9

3×9 = 27:

4 p + 3 = 27

Subtract 3 from both sides:

4 p + (3 - 3) = 27 - 3

3 - 3 = 0:

4 p = 27 - 3

27 - 3 = 24:

4 p = 24

Divide both sides of 4 p = 24 by 4:

(4 p)/4 = 24/4

4/4 = 1:

p = 24/4

The gcd of 24 and 4 is 4, so 24/4 = (4×6)/(4×1) = 4/4×6 = 6:

Lie detectors, also known as polygraph machines, measure physiological responses such as changes in heart rate, blood pressure, and respiration to determine if a person is telling the truth or not. However, these responses can be affected by many factors, such as anxiety or stress, and are not always reliable indicators of deception. In addition, people can learn how to manipulate their physiological responses in order to deceive the polygraph machine.

Answers

Answer: The vertex is at (-6, 2). The range is 2 < y < ∞.

Step-by-step explanation:

      y = |2x + 6| + 2 is almost in vertex form, which is y = |x - h| + k. We will divide both values by 2, so the 2 coefficient is on the outside, y = 2|x + 3| + 2.

      After this, we can see that the vertex is at (-h, k). This means the vertex is at (-3, 2).

      For the range, since this V (the shape of an absolute value graph) opens upwards, it will be everything greater than and equal to the y value of the vertex, in this case, 2. That means our range is;

Then the inverse Laplace transform is given as follows:

f(t) = e^(9t) + 9te^(9t).

How to obtain the inverse Laplace transform?

The function for this problem is given as follows:

F(s) = s/(s² - 18s + 81).

Completing the squares at the denominator, we have that:

F(s) = s/(s - 9)².

Applying partial fraction decomposition, the function can be defined as follows:

s/(s - 9)² = A/(s - 9) + B/(s - 9)²

Expanding the right side, we have that:

s/(s - 9)² = [A(s - 9) + B]/(s - 9)²

Hence:

As - 9A + B = s.

Then the system for the coefficients is given as follows:

A = 1.-9A + B = 10-> B = 9A -> B = 9.

Thus the function in the transform domain is of:

F(s) = 1/(s - 9) + 9/(s - 9)².

use implicit differentiation to find the derivative dy dx. b. find the slope of the curve at the given point. cos(y)

Answers

The slope of the curve at the given point is approximately -28

What is the derivative of a function?

Geometrically, the derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point. Its calculation, in fact, derives from the slope formula for a straight line, except that a limiting process must be used for curves.

To find the derivative of y with respect to x using implicit differentiation, we need to take the derivative of both sides of the equation cos(y) = 7x^4 - 7.

On the left side of the equation, we can use the chain rule to find the derivative of cos(y) with respect to x:

d/dx[cos(y)] = -sin(y) * dy/dx

On the right side of the equation, we can use the power rule to find the derivative of 7x^4 - 7 with respect to x:

[tex]d/dx[7x^4 - 7] = 28x^3[/tex]

Substituting these expressions into the original equation, we get:

[tex]-sin(y) * dy/dx = 28x^3[/tex]

To solve for dy/dx, we can divide both sides of the equation by -sin(y):

[tex]dy/dx = -(28x^3)/sin(y)[/tex]

To find the slope of the curve at the given point, we need to substitute the values of x and y into the expression for dy/dx.

The slope at (1, π/2). would be

slope = -(28((1)^3))/sin(π/2) = -28.

Suppose That A Vector Y Is Orthogonal To Vectors U And V. Show That Y Is Orthogonal To The Vector U + V.

Answers

A vector Y is orthogonal to vectors U and V, so Y is orthogonal to the vector (U+V).

In the given question,

Suppose that a vector Y is Orthogonal to vectors U And V.

We have to show that Y is orthogonal to the vector U + V.

As to vectors are orthogonal if and only if their dot product is zero.

So Y∙U = 0 and Y∙V = 0.

To prove that Y is orthogonal to the vector(U+V), we have to show that Y∙(U+V) = 0.

As dot product is distributive. Now

Y∙(U+V) = Y∙U + Y∙V

As Y∙U = 0 and Y∙V = 0. So

Y∙(U+V) = 0 + 0

Y∙(U+V) = 0

Hence, Y is orthogonal to the vector (U+V).

Answers

The value of x is 21

The measure of angle B is 28°

The measure of exterior angle ACD is 63°

Calculating the measure of angles

From the question, we are to determine the measure of the angles.

From the given diagram, we can write that

35° + (x + 7)° = 3x° (Exterior angle theorem)

Solve for x in the equation

35° + (x + 7)° = 3x°

35° + x° + 7° = 3x°

35° + 7° = 3x° - x°

42° = 2x°

Divide both sides by 2

42°/2 = 2x°/2

21° = x°

Therefore,

x = 21

The measure of angle B is

Measure of angle B = (x + 7)°

Measure of angle B = (21 + 7)°

Measure of angle B = 28°

The measure of exterior angle ACD

Measure of exterior angle ACD = 3x°

Measure of exterior angle ACD = 3(21)°

Measure of exterior angle ACD = 63°'

Hence, the measure of the exterior angle is 63°

se green's theorem to evaluate the line integral along the given positively oriented curve. c 5y 7e x dx 10x 9 cos(y2) dy c is the boundary of the region enclosed by the parabolas y

Answers

By using Green's Theorem, it can be calculated that

[tex]\int_c(5y+7e^x)dx+(10x+9cos(y^2))dy[/tex] = [tex]\frac{5}{3}[/tex]

What is Green's Theorem?

Green's Theorem gives a relationship between a line integral along a closed curve C and surface integral around plane region D bounded by C

By Green's Theorem,

[tex]\int_c Pdx+ Qdy = \int\int_D (\frac{\partial P}{\partial y} - \frac{\partial Q}{\partial x})dxdy[/tex]

To evaluate [tex]\int_c(5y+7e^x)dx+(10x+9cos(y^2))dy[/tex] using Green's Theorem,

Region is between the parabola [tex]y = x^2[/tex] and [tex]x = y^2[/tex]

To find point of intersection,

[tex]x = y^2\\x = (x^2)^2\\x = x^4\\x^4 - x = 0\\x(x^3 - 1) = 0\\x = 0 \ or \ x^3 - 1 = 0\\x = 0 \ or \ x^3 = 1\\x = 0 \ or \ x = 1[/tex]

Along y- axis the limit of integration is from y = [tex]x^2[/tex] to y = [tex]\sqrt{x}[/tex]

P = [tex]5y + 7e^x[/tex]

[tex]\frac{\partial P}{\partial y}[/tex] = 5

Q = [tex]10x + 9(cos(y^2))[/tex]

[tex]\frac{\partial Q}{\partial x}[/tex] = 10

By Green's Theorem,

[tex]\int_c(5y+7e^x)dx+(10x+9cos(y^2))dy[/tex]

= [tex]\int_{x = 0}^1\int_{y = x^2}^{\sqrt{x}}(10 -5)dxdy\\\\\int_{x = 0}^1\int_{y = x^2}^{\sqrt{x}}5dxdy\\\\\int_{x = 0}^1 5(\sqrt{x} - x^2)\\\\5[(\frac{2}{3})x^{\frac{3}{2}} - \frac{x^3}{3}]_0^1\\\\5(\frac{2}{3} -\frac{1}{3})\\\\\frac{5}{3}[/tex]

One possibility is to build coal-fired power plants, which cost $1300 per kW to construct and have an efficiency of 40 percent. Another possibility is to build clean-burning Integrated Gasification Combined Cycle (IGCC) plants where the coal is subjected to heat and pressure to gasify it while removing sulfur and particulate matter from it. The gaseous coal is then burned in a gas turbine, and part of the waste heat from the exhaust gases is recovered to generate steam for the steam turbine. The construction of IGCC plants costs about $1500 per kW, but their efficiency is about 48 percent. The average heating value of the coal is about 28,000,000 kJ per ton (that is, 28,000,000 kJ of heat is released when 1 ton of coal is burned). If the IGCC plant is to recover its cost difference from fuel savings in five years, determine what the price of coal should be in $ per ton.
