Answer:

4x + 2y

Step-by-step explanation:

1. 4x - 3(x - 2y) + 1/2(6x - 8y)

4x - 3x + 6y + 3x - 4y

4x + 2y

2. 4x - 3(x - 2y) + (1/2)(6x - 8y) =

4x - 3x + 6y  + 3x - 4y =

4x + y(6 - 4) = 4x + 2y = 2(2x + y)

Answer: Basically, the answer for the missing numbers are 6 and 12

Step-by-step explanation:

(i) Seems simple, I'll help

1. If 3 * 6 = (2 * 6) + (1 * 6), then simplified, it is 18 = 12 + 6

2. When 18 = 12 + 6, it becomes 18 = 18

The solution of the given equation r = 4g + 7 for g will be g = r/4 - 7/4.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

As per the given equation,

r = 4g + 7

Subtract by 7 on both sides,

r - 7 = 4g

Divide by 4 into both sides as

(r - 7)/4 = (4g)/4

r/4 - 7/4 = g

Hence "The solution of the given equation r = 4g + 7 for g will be g = r/4 - 7/4".

For any ε > 0, there exists a δ > 0 such that for any (a, c) in A x C, if ||(a, c) - (a_0, c_0)|| < δ, then ||(f(a), g(c)) - (f(a_0), g(c_0))|| < ε. This shows that the map f x g is continuous.

To show that the map f x g : A x C -> B x D is continuous, we need to demonstrate that it preserves the continuity of the individual functions f and g.

Let (a_0, c_0) be an arbitrary point in A x C, and let ε > 0 be given. Since f is continuous, there exists δ_1 > 0 such that for any point a in A, if ||a - a_0|| < δ_1, then ||f(a) - f(a_0)|| < ε/2.

Similarly, since g is continuous, there exists δ_2 > 0 such that for any point c in C, if ||c - c_0|| < δ_2, then ||g(c) - g(c_0)|| < ε/2.

Now, let δ = min(δ_1, δ_2). Consider any point (a, c) in A x C such that ||(a, c) - (a_0, c_0)|| < δ. This implies that both ||a - a_0|| < δ and ||c - c_0|| < δ, which in turn implies that ||f(a) - f(a_0)|| < ε/2 and ||g(c) - g(c_0)|| < ε/2.

By the triangle inequality, we have: ||(f(a), g(c)) - (f(a_0), g(c_0))|| = ||(f(a) - f(a_0), g(c) - g(c_0))|| <= ||f(a) - f(a_0)|| + ||g(c) - g(c_0)|| < ε/2 + ε/2 = ε.

a. To determine the value of a Call option with a strike price of $30 that expires at time t = 3, we need to calculate the option value at time t = 0 using the binomial model.

At each time period, there are two possible stock price movements: an upward jump and a downward jump. We can construct a binomial tree to represent these possibilities.

Starting at time t = 0, the stock price is $40. In the first time period, the stock can go up to $80 or down to $20. In the second time period, the stock can either go up to $160 or down to $40 (from $80), and down to $10 (from $20). Finally, in the third time period, the stock can reach $320, $80, $20, or $5.

To determine the value of the Call option at time t = 0, we need to calculate the option value at each node of the tree and work backwards. At the final nodes (t = 3), we compare the stock prices with the strike price of $30. If the stock price is higher than the strike price, the option value is the difference between the stock price and the strike price. If the stock price is lower, the option value is zero. We then propagate these option values back up the tree, applying the risk-neutral probability and discounting factors at each node, until we reach the initial node (t = 0).

b. Using the put-call parity, we can determine the value of the Put option at time t = 0 by considering the Call option value, the stock price, the strike price, and the present value of the strike price. The put-call parity relationship is given by:

Put Option Value + Stock Price - Call Option Value = Present Value of Strike Price.

In this case, we are given the Call option value from part (a) as the value at time t = 0. The stock price at time t = 0 is $40, and the strike price is $30. Since the interest rate is zero, the present value of the strike price is equal to the strike price itself.

Rearranging the put-call parity equation, we can solve for the Put option value:

Put Option Value = Call Option Value + Present Value of Strike Price - Stock Price.

Plugging in the known values:

Put Option Value = Call Option Value + $30 - $40.

Substituting the Call option value calculated in part (a), we can find the value of the Put option at time t = 0.

In this problem, we are given a binomial model with three time periods and certain stock price movements. We construct a binomial tree to represent the possible stock price paths and determine the value of the Call option at each node of the tree. By comparing the stock prices with the strike price at the final nodes, we calculate the option values at time t = 3 and propagate them back to time t = 0 using the risk-neutral probabilities and discounting factors.

For the Put option, we use the put-call parity relationship to determine its value at time t = 0. By rearranging the equation and substituting the known values, we can find the value of the Put option using the Call option value obtained in part (a). The put-call parity provides a relationship between the values of Put and Call options, stock price, strike price, and the present value of the strike price.

The 83 car stereos had a CD player only.

Given that,

348 car stereos were recently sold in a car audio store.

131 had a CD player, 133 had a cassette player, and 48 had both a CD and a cassette player.

Let's denote the number of car stereos having only a CD player as 'x'.

Using the given data, we can write,

Total number of car stereos with CD player = number of car stereos with CD player only + number of car stereos with both CD and cassette players

Now, using the values from the given data, we get:

131 = x + 48

Solving this equation for x, we get:

x = 131 - 48 = 83

Therefore, 83 car stereos had a CD player only.

The money was in the SACCO for a time of 0.78125 years.

Simple interest is defined as the interest obtained over the principal amount on a certain rate.

Given that,

Amount of money deposited or principal amount = 56,800

Rate of interest = 12% = 12/100 = 0.12

Final amount = 62,125

The formula for simple interest is,

A = P(1 + rt), where A is the final amount, P is the principal amount, r is the interest rate and t is the time.

Substituting,

56800 (1 + 0.12t) = 62125

1 + 0.12t = 1.09375

0.12t = 0.09375

t = 0.78125 years

Hence the time that the money kept for is 0.78125 years.

The value of the given expression [\(87^3+ 13^3/87^2 -87 * 13 + 13^2\)] by simplifying the numerator and denominator using suitable identities is 100.

We will first calculate the numerator:

As  (\(a^3\) + \(b^3\)) = (a + b)(\(a^2\) - ab + \(b^2\)) :

\(87^3\) + \(13^3\) = (87 + 13)(\(87^2\) - \(87 * 13\) + \(13^2\))

= 100(\(87^2\) - 87 * 13 + \(13^2\))

Now, calculate the denominator:

\(87^2 - 87 * 13 + 13^2\)

As,(\(a^2 -2ab +b^2\)) =\((a - b)^2\):

\(87^2 - 87 * 13 + 13^2 = (87 - 13)^2\)

\(= 74^2\)

So by solving the equation further:

\((87^3+13^3) / (87^2- 87 * 13+13^2) = 100*(87^2- 87 *13 + 13^2)/(87^2 - 87 * 13 + 13^2)\)

As we can see the numerator and denominator are the same expressions (\(87^2 - 87 * 13 + 13^2\)). so, they cancel each other:

\((87^3 + 13^3) / (87^2 - 87 * 13 + 13^2) = 100\)

So, the value of the given expression is 100.

Step-by-step explanation:

The gradient of a function points in the direction in which the function increases the fastest because it represents the direction of greatest increase of the function.

The gradient of a function is a vector that points in the direction of the steepest increase of the function at a particular point. This means that if we move in the direction of the gradient, the value of the function increases the fastest.

To understand why this is true, let's consider the definition of the gradient. The gradient of a function f(x) is defined as a vector of partial derivatives:

∇f(x) = (∂f/∂x1, ∂f/∂x2, ..., ∂f/∂xn)

Each component of the gradient vector represents the rate of change of the function with respect to the corresponding variable. In other words, the gradient tells us how much the function changes as we move a small distance in each direction.

When we take the norm (or magnitude) of the gradient vector, we get the rate of change of the function in the direction of the gradient. This means that if we move in the direction of the gradient, the value of the function changes the fastest, because this is the direction in which the function is most sensitive to changes in the input variables.
