Answer:

Using the formula provided, the value of that investment after 10 years is

A = P(1 + r/n) ^nt

   = 4500 x (1 + (4/100)/4)^(10 x 4)

   = 4500 x (1.01)^40

   = 6699.89$

Hope this helps!

:)

The value of that investment after 10 years is $6699.89

\(A = P(1 + r/n) ^{nt}\\\\= 4500 \times (1 + (4/100)/4)^(10 \times 4)\\\\= 4500 \times (1.01)^{40}\)

= 6699.89

The maximum profit is achieved when we sell an infinite number of units, which is not realistic.

The profit function P(x) is given by:

P(x) = R(x) - C(x)

Substituting the given functions for R(x) and C(x), we get:

P(x) = 600,000 + 7000x2 - 10x - (-1301 + 1000x + 200,000)

Simplifying and collecting like terms, we get:

P(x) = 6900x2 + 990x + 198,699

To maximize profit, we need to find the value of x that maximizes the profit function P(x). We can do this by finding the critical point of P(x), which is the point where the derivative of P(x) is zero or undefined.

Taking the derivative of P(x), we get:

P'(x) = 13,800x + 990

Setting P'(x) to zero and solving for x, we get:

13,800x + 990 = 0

x = -0.072

Since x represents the number of units sold, it doesn't make sense to have a negative value. Therefore, we can conclude that the critical point does not correspond to a maximum value of profit.

To confirm this, we can take the second derivative of P(x), which will tell us whether the critical point is a maximum or a minimum:

P''(x) = 13,800

Since P''(x) is positive for all values of x, we can conclude that the critical point corresponds to a minimum value of profit. Therefore, the profit function is increasing to the left of the critical point and decreasing to the right of it.

To maximize profit, we should consider the endpoints of the feasible range. Since we can't sell a negative number of units, the feasible range is [0, ∞). We can calculate the profit at the endpoints of this range:

P(0) = 198,699

P(∞) = ∞

Therefore, the maximum profit is achieved when we sell an infinite number of units, which is not realistic.

In summary, the company should aim to sell as many units as possible while also considering the cost of producing those units. However, the given profit function suggests that there is no realistic value of x that will maximize profit, and the maximum profit is achieved only in the limit as x approaches infinity.

The given statement is 1. Always true

2. Always true

3. Always true

4. Sometimes true

5. Never true

Statement 1: A line and a point are always coplanar.

Answer: Always true.

Reason: This statement is always true because a line and a point can always be found on the same plane. In Euclidean geometry, a plane is a flat surface that extends infinitely in all directions, and any two points on the plane can be connected by a straight line. Therefore, a line and a point will always lie on the same plane.

Statement 2: Congruent angles form vertical angles.

Answer: Always true.

Reason: Vertical angles are formed by the intersection of two lines. When two angles are congruent, it means they have the same measure. If two angles have the same measure and are formed by the intersection of two lines, then they are vertical angles. Therefore, congruent angles always form vertical angles.

Statement 3: Linear pairs that are congruent are right angles.

Answer: Always true.

Reason: A linear pair consists of two adjacent angles that share a common side and form a straight line. If the two angles of a linear pair are congruent, it means they have the same measure. In Euclidean geometry, a straight angle measures 180 degrees. If two angles in a linear pair are congruent and their measures add up to 180 degrees, then each angle must measure 90 degrees, which is the measure of a right angle. Therefore, linear pairs that are congruent are always right angles.

Statement 4: The sum of angles that form a linear pair is less than 180 degrees.

Answer: Sometimes true.

Reason: The sum of angles that form a linear pair is always equal to 180 degrees, not less than 180 degrees. This is based on the definition of a linear pair, which states that the two angles in a linear pair are supplementary, meaning their measures add up to 180 degrees. However, if the statement said "less than or equal to 180 degrees," then it would be always true.

Statement 5: Vertical angles are complementary.

Answer: Never true.

Reason: Vertical angles are not complementary. Complementary angles are two angles that add up to 90 degrees. Vertical angles, on the other hand, are a pair of non-adjacent angles formed by the intersection of two lines. They do not necessarily have any specific relationship to each other in terms of their angle measures. Therefore, vertical angles are not complementary by definition.

Answer:

The correct answer is 210 degrees.

Step-by-step explanation:

It's obviously obtuse so we can rule out 60 degrees. 105 degrees is closer to 90 degrees so we can rule that out. If it was 150 degrees, the angle would not look upside down. So, we can conclude that the measure of the angle would be 210 degrees.

A random variable that has a Binomial (10, 0.8) distribution. The correct selections are:

E(X) = E(Y) False

Var(X) Var(Y) True

P(X = 3) = P(Y = 7) True

P(Y = 10) = 0.810 False

P(X = 1) = 0.2 False

Using the properties of the binomial distribution, we can determine the following:

E(X) = np = 100.2 = 2 and E(Y) = np = 100.8 = 8, so the statement "E(X) = E(Y)" is False.

Var(X) = np(1-p) = 100.2(1-0.2) = 1.6 and Var(Y) = np(1-p) = 100.8(1-0.8) = 1.6, so the statement "Var(X) = Var(Y)" is True.

P(X=3) = (10 choose 3)(0.2)^3(0.8)^7 ≈ 0.201 and P(Y=7) = (10 choose 7)(0.8)^7(0.2)^3 ≈ 0.201, so the statement "P(X=3) = P(Y=7)" is True.

P(Y=10) = (10 choose 10)(0.8)^10(0.2)^0 = 0.1074 and P(X=1) = (10 choose 1)(0.2)^1(0.8)^9 ≈ 0.268, so the statement "P(Y=10) = 0.810" is False and the statement "P(X=1) = 0.2" is False.

Therefore, the correct selections are:

E(X) = E(Y) False

Var(X) Var(Y) True

P(X = 3) = P(Y = 7) True

P(Y = 10) = 0.810 False

P(X = 1) = 0.2 False

None of the statements a, b, c, or d can be determined to be true based solely on x ⇒ y and y ⇒ z.

Given that x ⇒ y and y ⇒ z, we can determine the valid implication between x and z.

To evaluate the possible truth values, let's consider the following cases:

If x is true and y is true:

Since x ⇒ y, the implication holds.

If y ⇒ z, the implication holds.

Therefore, z can be true in this case.

If x is true and y is false:

Since x ⇒ y, the implication does not hold.

The truth value of y ⇒ z is not relevant in this case.

Therefore, we cannot determine the truth value of z.

If x is false:

Since x ⇒ y, the implication holds vacuously, regardless of the truth value of y.

The truth value of y ⇒ z is not relevant in this case.

Therefore, we cannot determine the truth value of z.

Based on the above analysis, we cannot definitively conclude the truth value of z from the given information. Therefore, none of the statements a, b, c, or d can be determined to be true based solely on x ⇒ y and y ⇒ z.

In Mathematics, Probability is defined as the chances of an event will occur in random experiments. In simple words it is defined as the ratio of the number of favorable outcomes and the total number of outcomes. The Probability of an event is denoted by P(E)

Probability(E) = Favorable Outcomes/Total Outcomes

From the above observations,

the probability of choosing one jar from 3 jars = 1/3

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0.

Several real-world scenarios use exponential functions, including population increase, compound interest, radioactive decay, and the spread of diseases. For instance, an exponential function may be used to simulate the expansion of a bacterial population, with the rate of increase being proportional to the population size. Similarly, compound interest, which applies the rate of interest to the principal sum across a number of periods, can be represented by an exponential function.

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0 and k translates the graph of f up when k > 0 and down when k < 0.
