Y= v^2/2a solve for v

Answers

Answer 1

Solve for v:
Y = (a v^2)/2

Y = (a v^2)/2 is equivalent to (a v^2)/2 = Y:
(a v^2)/2 = Y

Divide both sides by a/2:
v^2 = (2 Y)/a

Take the square root of both sides:

Answer: v = sqrt(2) sqrt(Y/a) or v = -sqrt(2) sqrt(Y/a)

Answer 2

Final answer:

To solve for v in the equation y = v²/2a, multiply both sides by 2a and then take the square root of both sides which gives v = √(2ay).

Explanation:

The question requires us to solve the equation y = v²/2a for the velocity v. To isolate v, we multiply both sides of the equation by 2a, then take the square root of both sides.

Multiply both sides of the equation by 2a: 2ay = v²Take the square root of both sides to solve for v: v = √(2ay)

This mathematical process makes v the subject of the equation based on the given formula from kinematics. It's important to note that v will have two values, one positive and one negative, since taking the square root of a number yields both a positive and negative result.

The office of student services at a large western state university maintains information on the study habits of its full-time students. their studies indicate that the mean amount of time undergraduate students study per week is 20 hours. the hours studied follows the normal distribution with a standard deviation of six hours. suppose we select a random sample of 144 current students. what is the probability that the mean of this sample is less than 19.25 hours?

Answers

Answer: 45.03%

To find the answer for this problem, you first need to find the z-score for a value of 19.25.

The z-score is the number of standard deviations from the mean.

Here is the work for our z-score:

19.25 - 20 = -0.75 / 6 = -0.125

Now, you just have to use a standard normal distribution table and look up the probability for a z-score of -0.125. I used the average of the probability for z-scores of -0.12 and -0.13 to get 45.03%.

Final answer:

There is a 22.66% probability that the mean study time of a random sample of 144 students at the large western state university will be less than 19.25 hours.

Explanation:

To solve this problem, we need to use the formula for the z-score, which is (X - μ) / (σ / √n), where X is the sample mean, μ is the population mean, σ is the standard deviation, and n is the sample size.

Here, n=144, μ=20, σ=6 and X=19.25. Substituting these values into the formula, we get z = (19.25 - 20) / (6/√144) = -0.75.

The z-score tells us how many standard deviations the value is away from the mean. A negative z-score indicates that the data point is less than the mean.

To find the probability, we need to look up this z-score in the z-table, which gives the area to the left of the z-score on a standard normal distribution. The value associated with z=-0.75 on the table is approximately 0.2266, or 22.66%.

So, there is a 22.66% probability that the mean study time of a random sample of 144 students will be less than 19.25 hours.

What is the area of a triangle?

The area of a triangle is half the product of its base and its height.

[tex]Area \triangle = \dfrac{1}{2}\times base \times height[/tex]

In order to solve the problem, we will divide the given figure into two parts such that the first one will be a right-angled triangle while the second one is a semi-circle as shown below.

As we can see in the ΔABC, the height of the triangle is 3 units, while the length of the base of the triangle is 6 units. therefore, the area of the triangle can be written as,

[tex]\begin{aligned}\triangle ABC &= \dfrac{1}{2} \times height \times base\\\\&= \dfrac{1}{2} \times BC \times AB\\\\& = 0.5 \times 3 \times 6\\\\& = 9\rm\ unit^2 \end{aligned}[/tex]

Now, if we look at the semi-circle we will find that the diameter(BC) of the semi-circle is 3 units, therefore, the area of the semi-circle can be written as,

[tex]\begin{aligned}\text{Area of Semi-circle} &= \dfrac{\pi}{2}d^2\\\\ &= \dfrac{\pi}{2}(3)^2\\\\&= 14.137\rm\ units^2 \end{aligned}[/tex]

Further, in order to get the total area of the figure, simply add the two areas, therefore,

The area of the figure = Area of triangle + Area of the semi-circle

= 9 + 14.137

= 23.137 units²

Hence, the area of the figure that is made up of a triangle and a semicircle is 23.137 units².

Perpendicular lines refers to a pair of straight lines that intercept each other. The slopes of this lines are opposite reciprocal, meaning that it's multiplication is -1.

On this case they give you the equation of a line and a point, and is asked to find the y-intercept of the line that is perpendicular to the given one, and that passes through the given point.

The slope of the given line is -5/2, which means that the slope of a line perpendicular to this one, needs to be 2/5. Now you need to find the value of b or the y-intercept by substituting the given point into the formula y=mx+b, where letter m represents the slope.

y=mx+b Substitute the values of the given point and the slope

In the table below, x represents miles traveled and y represents the cost to travel by train.

What is the y-intercept of this function?

2.25
4.00
6.50
17.13

Answers

Answer:

Option B. 4

Step-by-step explanation:

By the table mentioned by you in the comments that the correct table is

x(miles) 2 5 8 12

y(cost) 8.5 15.25 22 31

As we know that the standard equation of a linear function is represented as

y = mx + c

For the points (2, 8.5) and (5, 15.25)

[tex]Slope(m)=\frac{15.25-8.5}{5-2}=\frac{6.75}{3}=2.25[/tex]

y = 2.25x + c

This function passes through (2, 8.5)

8.5 = 2.25×2 + c

c = 8.5 - 4.5 = 4

Therefore, y- intercept of the function will be option B. 4.

The y-intercept of this line is (4). Therefore, the estimated y-intercept of the function represented by the given data is 4.

To find the y-intercept of the function from the provided table, we look for the point where (x = 0), which represents the cost when no miles are traveled.

However, in the given table, there is no entry for $x = 0$, which means we don't have a direct value for the y-intercept from the given data.

To estimate the y-intercept, we can use the concept of linear interpolation.

We can assume that the relationship between miles traveled and cost is linear, so we can find the slope of the line passing through two consecutive points and use it to estimate the cost when (x = 0).

Using the points (2, 8.5) and (5, 15.25) from the table:

[tex]\[ \text{Slope} = \frac{{15.25 - 8.5}}{{5 - 2}} = \frac{6.75}{3} = 2.25 \][/tex]

Now, we can use the slope and one of the points to find the y-intercept using the point-slope form of the equation of a line: [tex]$y - y_1 = m(x - x_1)$.[/tex] Let's use the point (2, 8.5):

y - 8.5 = 2.25(x - 2)

y - 8.5 = 2.25x - 4.5

y = 2.25x + 4

The y-intercept of this line is (4). Therefore, the estimated y-intercept of the function represented by the given data is [tex]$\boxed{4.00}$[/tex].

Find the number of moles in 508 g of ethanol (C2H5OH).

Answers

To find the number of moles we start by calculating the molar mass:
M(C2H5OH) = 2*M(C) + 6*M(H) + M(O)
M(C2H5OH) = 2* 12.01 + 6* 1.008 + 16
M(C2H5OH) = 46.068g

This is mass of one mole of ethanol. Total mass of ethanol can be calculated by using formula:
m = N * M
Where:
m = total mass
N = number of moles
M = molar mass

We rearrange formula for N:
N = m / M
N = 508 / 46.068
N = 11.03

508g of ethanol contains 11.03 moles.

cant put it all in h

Answers

The correct answers are a) given; b) substitution property; c) subtraction property of equality; d) division property of equality; and e) reflexive property of equality.

Explanation:
The first line of your proof just restates what was given to us; therefore the reason is "given."

Between the first step and the second step, 11x was changed to 88; this is because x=8, and we substitute that in for x. That would give us 11*8=88, with the justification being substitution.

Between the second line and third line, 88 is cancelled from the left side and the -1 becomes -89; this happens because in order to cancel a positive 88, you must subtract it from both sides. This is the subtraction property of equality.

Between the third line and fourth line, -6 is cancelled from the left side and on the right side, -89 is changed to 89/6. This happens because in order to cancel the -6 that is beside the y (which means multiplication), we must divide both sides; this is the division property of equality.

The last step is to rewrite the equation with y on the left and the answer on the right; the reflexive property allows us to do that.

Final answer:

The correct properties of equality used to solve the equation given x = 8 are Given, Substitution Property, Subtraction Property of Equality, Division Property of Equality, and Symmetric Property of Equality.

Explanation:

The student has shared the steps of solving an equation and is asking for the correct sequence of properties used to solve it:

Given: 11x - 6y = -1; x = 8Substitute x: 88 - 6y = -1Subtract 88 from both sides: -6y = -89Divide by -6: y = 89/6State that 89/6 = y

The correct properties of equality should be applied as follows:

Given: Both the equation and x = 8 are provided information.Substitution Property: x = 8 is substituted into the equation for x.Subtraction Property of Equality: 88 is subtracted from both sides of the equation.Division Property of Equality: Both sides of the equation are divided by -6 to solve for y.Symmetric Property of Equality: Rearranges the equation to y = 89/6 for clarity.

B) -5: (-5 - -5)/(2 - 0) = 0/2 = 0
C) 0: (0 - -5)/(2 - 0) = 5/2 = 2.5
D) 1: (1 - -5)/(2 - 0) = 6/2 = 3
E) 2: (2 - -5)/(2 - 0) = 7/2 = 3.5
Now taking into consideration the mean value theorem, the value of the function f'(x) has to have the value equal to the average slope between the two points at at least one point between the two given values. For options A, B, C, and D it's possible for f'(x) to return values that make that slope possible. However, for option E, the mean value theorem indicates that f'(x) has to have the value of 3.5 for at least 1 point between x=0 and x=2. And since we've been told that f'(x) is less than or equal to 3 for all possible values of x, that is in conflict and f(2) can not have the value of 2.

Final answer:

Using the Mean Value Theorem, we can determine the possible values for f(2) which is D) 1

Explanation:

To find the possible values for f(2), we can use the Mean Value Theorem. Taking into consideration the mean value theorem, the value of the function f'(x) has to have the value equal to the average slope between the two points at at least one point between the two given values.

Since f(0) = -5 and f'(x) is less than or equal to 3 for all x, we know that f(2) must lie between -5 and -5 + 3(2) = 1.

Therefore, 1 is not a possible value for f(2), making the correct answer choice D) 1.

simplest form of the expression
3sqrt750+3sqrt2058-3sqrt48
can someone explain

Answers

First, you have to decompose the numbers under the square root:
750 = 2·3·5²
2058 = 2·3·7³
48 = 2⁴·3

Then, enlight all the exponents multiple of 2 (which is the index of the root):
3·√(2·3·5²) + 3·√(2·3·7²·7) + 3·√(2⁴·3)

At this point, you can take outside the square root everything that has an even number, and doing so you have to halve the exponent; you'll get:
3·5·√(2·3) + 3·7·√(2·3·7) + 3·2²·√3

You can now multiply:
15√6 + 21√42 + 12√3
which is the simplest form of your expression.
