f(x) = 3x - sin 4x

Answers

Answer 1

Graph of f(x) = 3x - sin 4x is using method of adding y-coordinates is attached below.

What is graphing method by adding ordinates?

The function y = 3x - sin 4x is actually the sum of two functions, y = 3x and y = - sin 4x.

For every value in the domain, there is a corresponding value in the range so that the point (x, 3x - sin 4x) is on the graph of y = 3x - sin 4x.

According to the given question:

Follow these steps to graphing the function:

1. Open an Excel file. Label the first column "x-coordinates," the second column "y = 3x," the third column "y = -sin 4x," and the fourth column "y = 3x - sin 4x." Set each column to round to four decimal places.

2. Set up the first column to range from -2pi to 2pi by intervals of pi/4.

3. Fill in the second and third columns by utilizing the equations y = 3x and y = - sin 4x, respectively.

4. Fill in the fourth column by simply adding the second and third columns.

5. Graph y = 3x - sin 4x  by using the x-coordinates from column A and the y-coordinates from column D.

Find the vertex of the parabola y=2(x-1)2+4.

Answers

Answer:

  (1, 4)

Step-by-step explanation:

You want the vertex of the parabola y=2(x-1)²+4.

Vertex form

The vertex form of the equation for a parabola is ...

  y = a(x -h)² +k . . . . . . 'a' is the scale factor; (h, k) is the vertex

Comparing the given equation to the vertex form, we see that ...

  a = 2

  h = 1

  k = 4

Then the coordinates of the vertex are (h, k) = (1, 4).

Part C : Determine the average rate of change between day 2 and day 4. Show your work (4 points )

Answers

Step-by-step explanation:

A

it is an exponential function.

for a linear function the charge rate would have to be constant between any pair of data points.

the change rate is

( f ( interval end ) - f ( interval begin ) ) /

( interval end - interval begin )

between (1, 2) and (2, 4) we have a charge rate of

(4 - 2) / (2 - 1) = 2

between e.g. (3, 8) and (4, 16) we have a charge rate of

(16 - 8) / (4 - 3) = 8

the change rate is therefore not constant, and it is not a linear function.

B

we see

x1 = 1, y1 = 2

x2 = x1 + 1, y2 = y1×2

x3 = x2 + 1, y3 = y2×2

we get the impression that

xn = xn-1 + 1 = x1 + (n - 1)

yn = yn-1 × 2 = y1 × 2^n

so, while going linearly along the x-axis, y increases by the powers of 2.

How many groups of participants would be needed to partially counterbalance a within-subjects experiment with three treatment conditions.

Every participant in an experiment is exposed to every treatment or condition in a within-subject design, sometimes referred to as a repeated measures design.

The term "between-subjects design" is comparable to this within-subjects design. People are solely assigned to one treatment in a between-subjects design. As a result, one therapy would be given to one group of volunteers, while a different treatment would be given to another group. After that, the variations between the two groups would be contrasted.

Answers

The probability that it will be detected in the next hour is 0.04.

For a system, a fault test each hour is a Bernoulli with success defined as detecting a fault.

The probability of success is 0.78

Let 'x' denote the number of tests conducted up to and including the test that detected a fault.

Then x* - Geometry (0.78).

The probability mass function of the random variable x is;

P(x) = { P( 1 - P )ˣ⁻¹   x = 1,2, . . .

         { 0                 otherwise

The Probability that a fault will be detected on the third hour, given that it has gone undetected during the first two hours is;

P(X = 3 / x = 2) = P(X = 3 and x > 2) / P(x > 2)

                        = P( x = 3 ) / 1-  P(x ≤ 2)

                        = P( x = 3 ) /  1-P(x = 1) - P(x = 2)

                        = P(3) /  1-P(1) - P(2)

                        = (0.78)(0.2)² / 1 - (0·78)(0.2) - (0.78)(0.2)

                        = (0.78)(0.04) / 1 - (0.78)(0.2) - (0.78)(0.2)

Answers

If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.

With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).

The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.

Answers:

question one:  6

question two: 1/3

==========================================

Explanation:

The side 12 from triangle A corresponds to the side 4 from triangle B.

The scale factor is A/B = 4/12 = 1/3 which tells us that sides in triangle B are 1/3 as long compared to sides in triangle A. This takes care of the second question.

We'll use this scale factor to determine the missing side of triangle B.

The side 18 in triangle A corresponds to this missing side in triangle B.

Take 1/3 of 18 to get (1/3)*18 = 6 which is that missing side.

Another way to look at it: Take any side of triangle B, triple it, and you'll get a corresponding side of triangle A.

well, 1.53 doesn't really come nowhere near close to round up to 10, so it boils down to 0, so 61.53 will just be 10 + 10 + 10 + 10 + 10 + 10 + 0 or just 60 once rounded up, now, what's 15% of 60?

well, we can get the 15% of 61.53 by just (15/100) * 61.53

however, the exercise is asking on rounding it up to "tens" first

61.53 has "10" six times plus 1.53, the rounding happens with the "surplus"

in this case the surplus is 1.53.

now, for rounding anything the tipover point is at the half, for $10 the half is $5, so if the amount is $5 or more, rounds up to $10, if less than that goes to 0.

1.53 is nowhere near 5, which is the halfpoint or tipover point, because of that, it rounds up to 0, so 61.53 rounded up to "tens" only will be "six tens" only, or 60.

elect the correct answer. A game involves rolling a fair six-sided die. If the number facing upward on the die is a whole number multiple of three, the player wins an amount equal to the number on the die times $20. If the number is not a multiple of three, the player gets nothing. What is the expected value of a player's winnings on each roll?

Answers

The expected value of a player's winnings on each roll is: $30.

How can we calculate the expected value of a player's winnings on each roll?

We can calculate the expected value of a player's value on each winning by first understanding that there are only two multiples of three on the six-sided die. These multiples are 3 and 6.

So, if 3 is obtained facing upward, the player wins 3 × 20 = $60

Also, if the player obtained 6 facing upward, the player wins 6 × 20 = $120

So, the total amount is $180.

However, the question expects us to calculate the expected value of a player's winnings on each roll. Thus, we will have $180 ÷ 6 = $30.
