Step-by-step explanation:

The Equation of a Line

The equation of the line in slope-intercept form is:

\(y=mx+b\)

Where m is the slope and b the y-intercept.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

\(\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\)

We are given the points (5,2) and (0,-1), thus:

\(\displaystyle y-2=\frac{-1-2}{0-5}(x-5)\)

Operating:

\(\displaystyle y-2=\frac{-3}{-5}(x-5)\)

\(\displaystyle y-2=\frac{3}{5}(x-5)\)

To find the slope-intercept form, we continue to simplify the expression:

Removing the parentheses:

\(\displaystyle y-2=\frac{3}{5}x-\frac{3}{5}\cdot 5\)

\(\displaystyle y-2=\frac{3}{5}x-3\)

Adding 2:

\(\displaystyle y=\frac{3}{5}x-3+2\)

\(\mathbf{\displaystyle y=\frac{3}{5}x-1}\)

Answer:

B. ∆XYZ, in which m∠X = 10° and m∠Z = 25°

Step-by-step explanation:

∆ABC

m∠A = 10°

m∠B = 145°

m∠C = 180° - (m∠A + m∠B )

= 180° - (10° + 145°)

= 180° - 155°

m∠C = 25°

∆XYZ

m∠X = 10°

m∠Z = 25°

m∠Y = 180° - (m∠X + m∠Z)

= 180° - (10° + 25°)

= 180° - 35°

m∠Y = 145°

so,

m∠A = m∠X = 10°

m∠C = m∠Z = 25°

m∠B = m∠Y = 145°

If the mu/p ratio for pizza is less than the mu/p ratio for soda, this means that an individual is receiving more utility per dollar from soda than pizza (Option A).

In other words, the marginal utility of spending one more dollar on soda is greater than spending one more dollar on pizza. This doesn't necessarily mean that the price of pizza is lower than the price of soda (Option B) or that the price of pizza is lower than the price of coke (Option C), as the prices of the two goods could be equal or have different relative prices. It also doesn't mean that the MU of pizza is lower than the MU of soda (Option D), as the MU of each good could be different regardless of their price ratios.

The final answer is: Option A

What is linear algebraic equations?

Unknown quantities can often be determined using linear algebra. Among linear algebra's practical uses are the following: to calculate time, distance, or speed. used by linear maps to translate a three-dimensional image into a two-dimensional plane.

Mathematical structures that can be closed under addition and scalar multiplication are the focus of this area of study, which also encompasses the theory of linear equation systems, matrices, determinants, vector spaces, and linear transformations.

Assume that Dupe is x years old and Olu is y. We may create two linear algebraic equations using the given data:

x + y = 25

(x - 8) = 2(y - 8)

This system of linear equations can be transformed into the following by using a little algebraic trickery:

x + y = 25

x - 2y = -8

To obtain x = 14 and y = 11, construct an augmented matrix and use either Gaussian elimination or Gauss-Jordan elimination.

The number of edges that the prism has is

When a plane intersects a prism, the shape formed is known as the cross section. The cross section of the prism will have the same form as the base if it is divided by a plane that runs horizontally and parallel to the base.

A prism is a 3-dimensional object with two congruent and parallel bases (which are polyggonal) connected by rectangular lateral faces. The number of edges of a prism is equal to the sum of the number of edges of the two bases and the number of lateral faces.

Each base of the prism has n edges, so the two bases together have 2n edges. The number of lateral faces of the prism is equal to the number of edges of one of its bases, so there are n lateral faces. Each lateral face has 4 edges, so the total number of edges of the lateral faces is 4n.

Therefore, the total number of edges of the prism is equal to the sum of the number of edges of the two bases (2n) and the number of lateral faces (4n), which is 2n + 4n = 6n.

In conclusion, the cross section of a prism is an n-sided polygon and the prism has n + 2 edges.

Step-by-step explanation:

Answer:

The length of line segment AB is 5.

Step-by-step explanation:

Envision a right triangle that has one acute vertex at (-4, 2) and the other at (0, 5).  The horizontal distance from the first to the second vertex is 0 - (-4) = 4, and the vertical distance is 5 - 2 = 3.

Then the length of the hypotenuse, according to the Pythagorean Theorem, is

d = √(4² + 3²) = 5

The length of line segment AB is 5.  Note that this is a 3-4-5 triangle, and so 3² + 4² = 5²

Using the Black-Scholes-Merton equation and the concept of risk-neutral valuation, we can show that the price of the security at time t < T is given by c(t, S(t)) = S(0)ke^(k-1)(r+k^2σ^2)(T-t).

To derive the price formula, we start with the Black-Scholes-Merton equation, which describes the dynamics of the price of a security. The equation is given by:

dS(t) = μS(t)dt + σS(t)dW(t)

where S(t) is the price of the security at time t, μ is the drift or expected return, σ is the volatility, W(t) is a standard Brownian motion, and dt represents an infinitesimal time interval.

To price the security, we apply risk-neutral valuation, which assumes that the market is risk-neutral and all expected returns are discounted at the risk-free rate. We introduce a risk-free interest rate r as the discount factor.

Using risk-neutral valuation, we can write the price of the security at time t as a discounted expectation of the future payoff at time T. Since the security pays S(T)k at time T, the price can be expressed as: c(t, S(t)) = e^(-r(T-t)) * E[S(T)k]

To simplify the expression, we need to calculate the expected value of S(T)k. By applying Ito's lemma to the function f(x) = x^k, we obtain: df = kf' dS + (1/2)k(k-1)f''(dS)^2

Substituting S(T) for x and rearranging the terms, we have: d(S(T))^k = k(S(T))^(k-1)dS + (1/2)k(k-1)(S(T))^(k-2)(dS)^2

Taking the expectation and using the risk-neutral assumption, we can simplify the expression to: E[(S(T))^k] = S(t)^k + (1/2)k(k-1)σ^2(T-t)(S(t))^(k-2)

Finally, substituting this into the price formula, we get: c(t, S(t)) = S(t)^k * e^(k-1)(r+k^2σ^2)(T-t)

Therefore, the price of the security at time t < T is given by c(t, S(t)) = S(0)ke^(k-1)(r+k^2σ^2)(T-t).

Answer: Equation using slope intercept from y= -(5/2)x +26

Step-by-step explanation:

Write an equation of the line (in slope-intercept form) that is perpendicular to the line y=(2/5)x-(1/5) and contains the point (-4,16).

The line given is y=(2/5)x-(1/5)

Which we can rewrite in y= mx+b form as

y=(2/5)x-(1/5)

So slope of this line is (2/5)

A line perpendicular will have slope = -(5/2) ,  Which is (1/m)

Equation of new line will be

y = -(5/2)x +b

Now we need to find b

Plug in Point (-4,16)

Replace with the (-4,16) values

16 = (5/2) (-4) +b

solve it, 16=(-10)+b

Step-by-step explanation:

\(q = \frac{2-4t}{t+3}\\\\\)

Cross multiply,

q(t+3) = 2 - 4t        

Use distributive property: a*(b + c) =(a*b) + (a*c)

qt + 3q = 2- 4t

qt + 4t + 3q = 2

Answer:

The opposite of integer 4 units away from -6 is 10.

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

Now consider a number line.

The number that is 4 units away from -6 is -10.

So, the number is -10.

The opposite of -10 will be:

- (-10) = 10

Thus, the opposite of integer 4 units away from -6 is 10.
