The statement is false. The solution set of a linear system can only be expressed using a parametric equation if the system has at least one solution.

Equation of this sort is known as a parametric equation; it uses an independent variable known as a parameter (commonly represented by t) and dependent variables that are specified as continuous and independent of other variables functions of the parameter Multiple parameters may be utilized as needed.For example, the following equation can be represented as a pair of equations in parametric form rather than the equation in Cartesian form: Parameterization, It effectively differentiates and integrates curves by converting a function into parametric form.

Explanation:

The points b and e are relative max points. They are the highest point for their given neighborhood/region. In other words, they are the peak of the mountain for that little area.

In this case, point b is also the absolute maximum because it is the highest point of every point on the entire curve.

Answer:

Step-by-step explanation:

(2x-5)² = (2x)² - (2x⋅5) - (2x⋅5) + (-5)²

= 4x² - 20x + 25

Answer:

4x^2-20x+25 DOES equal (2x-5)^2.

Step-by-step explanation:

By factoring 4x^2-20x+25, we have:

4x^2-20x+25 = (2x - 5)(2x - 5) because of the order for this multiplication as FOIL, or first, outside, inside, and last.

Firstly, we take the first numbers 2x * 2x = 4x, so we put this down as

4x^2

We then take the outside numbers 2x * -5 = -10x and also put this down

4x^2 - 10x

We then take the inside numbers 2x * -5 = -10x again and put this down

4x^2 - 10x - 10x, or 4x^2 - 20x

We then take the last numbers -5 * -5 = +25 and put this down

4x^2 - 20 + 25

We now know that 4x^2 - 20 + 25 is equal to (2x - 5)(2x - 5), and

(2x - 5)(2x - 5) is equal to (2x - 5)^2.

The heat equation of the temperature of a solid material is a partial differential equation that governs how heat energy is transferred through a solid material.

The mixed boundary conditions in this context refer to a combination of boundary conditions where one end of the solid material is fixed and the other end experiences heat.

In other words, mixed boundary conditions are boundary conditions that consist of different types of boundary conditions on different parts of the boundary of a domain or region. They are a combination of Dirichlet, Neumann and Robin boundary conditions. When applying these boundary conditions, it is important to ensure that they are consistent with each other to ensure a unique solution to the heat equation.

In the case of fixing one end of the solid material and applying heat to the other end, the boundary conditions can be expressed as follows:

u(0,t) = 0 (Fixed end boundary condition)

∂u(L,t)/∂x = q(L,t) (Heat boundary condition)

where u(x,t) is the temperature at position x and time t, L is the length of the solid material, and q(L,t) is the heat flux applied at the boundary x = L.

Answer:

B.

Step-by-step explanation:

Answer:

b. To find the probability a customer who ordered pancakes came to thediner late, we need to look at the intersection of the "pancakes" row and the "late" column. This gives us a probability of 0.1, or 10%

c. To determine whether breakfast choice and meal time are independent, we need to see if the probability of one event changes based on the occurrence of the other event. In this case, it seems that breakfast choice and meal time are not independent, as the probability of being late seems to differ based on what breakfast item the customer chose. For example, the probability of being late is higher for customers who ordered pancakes compared to those who ordered cereal. Therefore, the choice of breakfast item appears to be related to the probability of being late, and so breakfast choice and meal time are not independent.

In MATLAB, you can symbolically solve and plot the solution of the second-order differential equation d^2y/dt^2 = a^2y, with initial conditions y(0) = b and y'(0) = 1, using the symbolic math toolbox.

Here's the MATLAB code to solve and plot the solution:

```matlab

syms t a b y(t)

eqn = diff(y, t, 2) == a^2 * y;  % Define the differential equation

cond1 = y(0) == b;  % Initial condition y(0) = b

cond2 = subs(diff(y, t), t, 0) == 1;  % Initial condition y'(0) = 1

sol = dsolve(eqn, cond1, cond2);  % Solve the differential equation

t_vals = -10:0.1:10;  % Define the interval for plotting

y_vals = subs(sol, t, t_vals);  % Substitute t values in the solution

Given, Angular acceleration α(t) = (6.0 rad/s^4)t^2, Initial velocity u = 0, Final velocity v = ?, Angular displacement θ = 13 × 2π rad = 26π rad. So, it takes 13.6 seconds to make 13 revolutions.

We have the relation, α = (v - u)/t , We know that, α(t) = (6.0 rad/s^4)t^2∴ (v - u)/t = (6.0 rad/s^4)t^2(v - 0)/t = (6.0 rad/s^4)t^2v = (6.0 rad/s^4)t^3 ----(1)

Now, Angular displacement θ = (1/2)(u + v)t

Since the wheel starts from rest, u = 0

∴ (1/2)(0 + v)t = θvt = (2θ)/v

Substitute the value of v from equation (1),

t = (2θ)/((6.0 rad/s^4)t^3)= (θ/(3.0 rad/s^2))^(1/3)t = [(26π)/(3.0 × π^2)]^(1/3)= 13.6 s (approx)

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit. This may enable more competitive pricing on the market or result in larger profit margins.

Second, raising returns to scale can result in better operational effectiveness and resource utilisation. As the company grows in size, it will be able to use resources more wisely and profit from production volume-related synergies.market prices that are competitive.

The answers that  best explains how we check to make sure that this condition is met is: c. Make sure there is similar spread around the sample mean of y.

The equal spread condition states that the residuals (differences between the actual and predicted values of y) should have roughly equal variance at each value of x.

To check if this condition is met, we examine the residual plot, which is a scatterplot of the residuals versus the independent variable x. If the spread of residuals around the mean is roughly equal for all x, then the equal spread condition is satisfied.
