W i directly proportional to the cube root of X
X i increaed by 50%
Work out percentage increae in W

Answer:

3 units.

Step-by-step explanation:

In the equation x = 1/12 (y-1)², the vertex of the parabola is at the point (1,1). The focus of the parabola is located a distance called the "focal length" from the vertex.

The focal length is given by the formula f = 1/(4*p), where p is the coefficient of the x term in the standard form of the equation of the parabola.

In this case, the coefficient of the x term is 1/12, so the focal length is f = 1/(4*(1/12)) = 3. This means that the distance from the focus to the vertex is 3 units.

The level of a line's slope indicates its steepness.

The slope is computed mathematically as "rise over run" (change in y divided by change in x).

In accordance with the slope equation, the slope of such a line may be determined by dividing the rise of the line between two positions by the run of the same line between the same two sites.

The above equation is a standard straight-line equation, and we are asked to change it to slope-intercept form, which is given as y = mx + c. "m" denotes the slope of the line and "c" denotes its intercept.

Now, let's take an example ,

2x - 3y ≤ 12

or, - 3y ≤ 12 - 2x

or, 3y ≤ 2x - 12

or y ≤ (2/3)x - 4

So, here slope (m) = 2/3, graph is shown below:

a) Differential equation (initial value problem) for the mass of the copper sulfate would be dm/dt = 0

b) m(t)=0

What is Differential equation?

A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions. Applications typically use functions to describe physical quantities, derivatives to indicate the rates at which those quantities change, and differential equations to create a relationship between the two.

a) Solution is flowing out of the tank. This can be expressed mathematically as:

dm/dt = (flow rate of solution into tank) - (flow rate of solution out of tank)

= (2 l/min) - (2 l/min)

= 0

Therefore, the differential equation for the mass of the copper sulfate in the tank is:

dm/dt = 0

This is a simple differential equation with a constant coefficient of 0, and it can be easily solved by integrating both sides of the equation with respect to time.

b. To solve the differential equation, we can write:

m(t) = integral(0, t, dm/dt)

= integral(0, t, 0)

= 0

Since the coefficient of the derivative is 0, the solution to the differential equation is a constant function with a value of 0. This means that the mass of the copper sulfate in the tank will remain constant over time, regardless of the flow rates of the solution into and out of the tank.

The mean of 1, 2, 3, 4, and 5 is 3, and the standard deviation is 1.58.

To find the mean, you add up all the numbers and divide by the number of numbers you have.

To find the standard deviation, you first find the difference between each number and the mean, square each of these differences, add them up, and divide by the number of numbers you have. Then, you take the square root of this result.

Mean = (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3

Standard deviation = sqrt(((1 - 3)^2 + (2 - 3)^2 + (3 - 3)^2 + (4 - 3)^2 + (5 - 3)^2) / 5) = sqrt((4 + 1 + 0 + 1 + 4) / 5) = sqrt(10 / 5) = sqrt(2) = 1.58

Yes, since the midpoint of a line segment is at an equal distance from the two endpoints, it is said to be equidistant from them.

A point is said to be equally far from a group of objects if there is an equal distance between it and each member of the group.

The perpendicular bisector of two specified (different) points is their location in two-dimensional Euclidean geometry. The locus of points equidistant from two provided points in three dimensions is a plane, and generalizing further, the locus of points equidistant from two given locations in n-dimensional space is a (n1)-space.

The circumcenter of a triangle is a location that is equally spaced from each of the three vertices. This point exists in every non-degenerate triangle. The circumcentre of cyclic polygons is equally far from all of the vertices, and this conclusion may be generalized to them.

Application of the concept of fractions in real life

In real life, the concept of a fraction is often used when we want to talk about a part of a whole, a part of something, a part of a group of people, etc.

In the problem above it is stated that initially the bunny has food, which will be eaten in the morning and at night, and some food was left over.

If x is the total food for the bunny, then the given problem can be written mathematically as follows:

breakfast (a) : a = 1/2x

dinner (b)

food left (c) : c = 1/5x

Then the mathematical expression that describes the above situation is as follows:

x = a + b + c

  = 1/2x + b + 1/5x --> then we make the denominators the same, so it becomes:

           x = 5/10x + b + 2/10x

              = 7/10x + b

x - 7/10x = b

The average age of lifeguards in Ocean City is significantly greater than 24 years at a 5% level of significance.

What is Standard deviation?

Standard deviation is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.

To determine whether there is evidence to support the claim that the average age of lifeguards in Ocean City is greater than 24 years at a 5% level of significance, we need to perform a one-tailed t-test. A one-tailed t-test is used to test whether the mean of a sample is significantly greater than (or less than) a certain value.

To perform the t-test, we first need to calculate the t-statistic, which is defined as:

      [tex]t = (mean - null value) / (standard error / \sqrt{n} )[/tex]

where mean is the mean age of the sample of lifeguards, null value is the value that the null hypothesis is testing against (in this case, 24 years), standard error is the standard error of the mean age, and n is the number of lifeguards in the sample.

Plugging in the values from the problem, we get:

           [tex]t = (24.7 - 24) / (standard \ error / \sqrt{36} )\\\\= 0.7 / (standard\ error / 6)[/tex]

The standard error of the mean is a measure of the variability of the sample mean, and is calculated as:

   [tex]standard \ error = population \ standard\ deviation / \sqrt{(n)}[/tex]

Plugging in the values from the problem, we get:

standard error = / sqrt(36) = / 6 =

Substituting this value back into our expression for t, we get:

    t = 0.7 / ( 6)

      = 1.8

For a one-tailed t-test at a 5% level of significance, the critical value is 1.645. This means that if the t-statistic is greater than 1.645, we can reject the null hypothesis and conclude that there is evidence to support the claim.

So we can reject the null hypothesis and conclude that there is evidence to support the claim that the average age of lifeguards in Ocean City is significantly greater than 24 years at a 5% level of significance.
