What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                          Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Anchor  weighing = 100 lbs

   given 3  lb/ft

  the combined weight  = 3( 25 -y ) + 100

                                 = 175 - 3y

    the workdone on small solution is = (175 - 3y)Δy

                      w = ∫₀²⁵ (175 - 3y) dy

                        = 175[y]²⁵₀- 3/2[y²]²⁵₀

                       = 175 [ 25 - 0 ] - 3/2 [ 25²- 0²]

                       = 3437.5  feet - lbs

Answer:

-9x^2+13x+8

Step-by-step explanation:

Combine like terms-

(x^2 + 8x + 8) + (-10x^2 + 5x)

8x+5x = 13x

(x^2 + 8x + 8) + (-10x^2 + 5x)

-10x^2+x^2 = -9x^2

(x^2 + 8x + 8) + (-10x2 + 5x)

The equation of the line is  f(X)=(-1/6)x—(19/6)

What is equation?

In arithmetic, an equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.

Main body:

first linear functions have their general form as y= mx + c, where y belongs to the range and X belongs to the domain, m is the slope, and c is the y-intercept.

So using f(x) =y

Given that f(—5)=-4 , X=—5 and y=-4, hence by substituting into the general eqn y= mx+c, You get

-4= -5m+c ------(1)

Also given that f(1)=—3, X=1 and y=—3, hence by substituting into the general eqn y= mx+c, You get

-3= m+c --—-(2)

Solve equation (1) and (2), simultaneously to find the value of m and c. After which you will substitute into y=mx+c or f(X)=mx+c to get your f(X).

Note: you will get m=—1/6 and c=-19/6, from the simultaneous equations.

Hence f(X)=(-1/6)x—(19/6) and correct option is D.

Yes, y = e^xy  is an implicit solution of the differential equation

(1-xy)y'=y^2

Here,

The differential equation (1-xy)y' = y^2

And,  y = e^xy is an implicit solution of the differential equation

(1-xy)y'=y^2.

What is Differential equation?

A differential equation is a mathematical equation that relates some function with its derivatives.

Now,

To show y = e^xy is an implicit solution of the differential equation

(1-xy)y'=y^2, we have to find the solution of differential equation.

The differential equation is;

\((1-xy)y'=y^2\\\\\\\\\)

\((1-xy) \frac{dy}{dx} = y^2\)

\(\frac{dx}{dy} + \frac{x}{y} = \frac{1}{y^{2} }\)

It is form of  \(\frac{dx}{dy} + Px = Qy\),

Where, P is the function of y and Q is the function of x.

Hence, Integrating factor = \(e^{\int\limits {\frac{1}{y} } \, dy} = e^{lny} = y\)

The solution is;

\(x y = \int\limits {\frac{1}{y^{2} }y } \, dy + c\)

\(xy = lny + c\)

Take c = 0, we get;

\(xy = lny\\\\y = e^{xy}\)

Hence, y = e^xy  is an implicit solution of the differential equation

Step-by-step explanation:

Using the remainder theorem when , when the value of x + 2 is substituted into the polynomial if it's a factor it will produce a result of zero else any number will prove that it's not a factor.

So we have

x + 2 = 0

x = - 2

Substitute the value of x into the polynomial

That's

\(p( - 2) = 2 ({ - 2})^{4} + 6( { - 2})^{3} - 5( - 2) - 10 \\ = 2(16) + 6( - 8) + 10 - 10 \\ = 32 - 48 \\ = - 16\)

Since it leaves a remainder of - 16 (x + 2) is not a factor of the polynomial

The appropriate value for M1 in the linking constraint for product A is $17.

In the given scenario, the decision variable Yi is defined as 1 if the amount of product i produced (Xi) is greater than 0, and 0 if Xi equals 0. This implies that Yi represents whether or not product i is produced. In this case, we are dealing with product A.

The linking constraint is used to ensure that if product A is produced (Yi = 1), then the amount produced (Xi) must be greater than 0. This can be expressed as Xi ≥ Yi * M1, where M1 is a sufficiently large value that ensures the constraint holds.

Since the profit per unit of A is $17, setting M1 equal to this value guarantees that if Yi is 1 (product A is produced), then Xi must be greater than 0 (at least one unit of A is produced). This ensures that the linking constraint is satisfied and reflects the condition that the company can sell all the units it produces.

To find the least-squares solution of the linear system using the projection onto the column space of a matrix A, we can use the formula x = (A^T A)^-1 A^T b, where b is the vector on the right-hand side of the system. In this case, A is the given matrix and b is not specified.

The least-squares solution of a linear system Ax=b is the vector x that minimizes the Euclidean distance between Ax and b. Geometrically, this corresponds to finding the projection of b onto the column space of A. The formula x = (A^T A)^-1 A^T b gives us the coordinates of the projection in terms of the columns of A. In other words, we are finding the coefficients that give us the linear combination of the columns of A that best approximates b.

In this specific case, we are given the projection of some vector onto the column space of a matrix A. We cannot find the least-squares solution without knowing b. However, if we had both the projection and b, we could use the formula x = (A^T A)^-1 A^T b to find the least-squares solution.

Step-by-step explanation:

a) Median will be an appropriate measure for the distribution. b) Mean will be an approprate measure for the distribution.

Here we already have the data available to us. From the data, we can clearly see that

Mode < Mean < Median

Hence this is a negatively skewed distribution.

Therefore the appropriate measure of central tendency for this distribution will be the median. The median will tell us the point at which the frequency is divided by 50%.

Hence we can say that the median will a more appropriate measure.

Now if the data has another aspect of sex included, then the frequency column would be divided into separate columns with each gender identity taking up its own column.

Since now this will become multivariate data, the best measure of central tendency will be Mean.

The difference in the measure of central tendency will depend upon how skewed the data for every sex will be. For example, if in a country, men preferred to be educated over women, then the mean for men will be a lot higher than that of women. On the other hand, the EDUC for women will be a lot lower.

With Alpha set to .05, increasing the sample size would not directly reduce the probability of a Type I error. The probability of a Type I error is determined by the significance level (Alpha) and remains constant regardless of the sample size.

However, increasing the sample size can indirectly affect the probability of a Type I error by increasing the statistical power of the test. With a larger sample size, it becomes easier to detect a statistically significant difference between groups, reducing the likelihood of falsely rejecting the null hypothesis (Type I error).

Increasing the sample size generally decreases the probability of a Type II error, which is failing to reject a false null hypothesis. With a larger sample size, the test becomes more sensitive and has a higher likelihood of detecting a true effect if one exists, reducing the likelihood of a Type II error. However, it's important to note that other factors such as the effect size, variability, and statistical power also play a role in determining the probability of a Type II error.

We can use the formula for exponential growth to find the rate at which the sunfish gains mass:

M(t) = M(0) * e^(kt)

where:

M(0) = the initial mass of the sunfish (which we don't know)

k = the growth rate constant (which we also don't know yet)

t = the elapsed time since the sunfish was born (in days)

e = the mathematical constant approximately equal to 2.71828...

We are given the formula for M(t), which is:

M(t) = 4 * (81/49)^t

This means that M(0) = 4 * (81/49)^0 = 4.

To find the growth rate constant k, we can use the fact that the sunfish gains 2/7 of its mass every day. This means that the daily growth rate is 2/7 of the current mass. In other words, the daily growth rate is:

(2/7) * M(t)

We can relate this to the exponential growth formula by taking the derivative of M(t) with respect to t:

dM/dt = k * M(t)

Taking the derivative of M(t), we get:

dM/dt = ln(81/49) * 4 * (81/49)^t

Setting this equal to the daily growth rate, we get:

(2/7) * M(t) = ln(81/49) * 4 * (81/49)^t

Simplifying this expression, we get:

k = ln(81/49) * 4/7

Using a calculator, we can evaluate this expression to get:

k ≈ 0.0919

Therefore, the rate at which the sunfish gains mass is given by:

dM/dt = 0.0919 * M(t)

To find out how much mass the sunfish gains in one day, we can substitute M(t) = 4 * (81/49)^t into this formula and evaluate it at t = 1 (since we want to know the daily rate of change):

dM/dt = 0.0919 * 4 * (81/49)^1

dM/dt ≈ 0.54

This means that the sunfish gains 0.54 milligrams every day. To express this as a fraction of its mass, we can divide by the current mass:

(0.54/4) ≈ 0.1375

So the sunfish gains approximately 2/7 (or 0.2857) of its mass every 2.08 (or 7/2.54) days. Rounded to two decimal places, this is 0.14 or approximately 2/7 of its mass every 2.08 days.

Answer: -3/5, -3/8, -1/4, 1/8, 1/5

Step-by-step explanation:

Since f'(5) = 8 and f'(10) = -3, we can conclude that the function f(x) has a local maximum at x = 5 and a local minimum at x = 10.

This is because the sign of the derivative of a function changes from positive to negative as we move from left to right through a local maximum, and changes from negative to positive as we move from left to right through a local minimum.

In this case, since f'(5) = 8 (positive) and f'(10) = -3 (negative), the slope of the tangent line to the graph of f(x) is increasing at x = 5, indicating a local maximum, and decreasing at x = 10, indicating a local minimum. Therefore, we can conclude that f(x) has a local maximum at x = 5 and a local minimum at x = 10.
