Now let express Mr Mady ending balance after one year algebraically by using this formula

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

Where:

A = Future value

P=Principal

r= Rate

N=Number of period

Let plug in the formula

A = P(1 + 0.0411/4)^4

HOPE THIS HELPSSSS!!!!!!!!!!!!!+

Answer:

-4

Step-by-step explanation:

4n+8-2n=0 2n=-8.n=-4

Explanation:

We'll let you draw the diagram. Here are some possible equations. We have listed the shortest sequence first.

(a) 24 = (10 + 10 + 4) = (8 + 8 + 8) = (10 + 8 + 4 + 2)

(b) 17 = (10 + 3 + 2 + 2) = (10 + 3 + 3 + 3 - 2) = (3 + 3 + 3 + 3 + 3 + 2)

(c) 15 = (11 + 4) = (6 + 6 + 3) = (4 + 4 + 4 + 3)

(d) 27 = (19 + 8) = (19 + 12 - 4) = (19 + 12 + 4 - 8)

In the above case, the possible point system will be:

1st choice vote: 4 points

2nd choice vote: 2 points

In arranging for the turtle to win in this point framework, the point values relegated for 1st choice and 2nd choice votes have to be meet the taking after criteria:

Lets say:

1st choice vote: 4 points

2nd choice vote: 2 points

Thus by the use of these point values, the turtle would have the next chance of winning since 1st choice votes would be worth more point (4 point ) compared to 2nd choice votes (3 point ). This would push individuals to select the turtle as their 1st choice, because it would allow the turtle a better add up to point gains and increase its chances of winning.

We have demonstrated using the Intermediate Value Theorem that the polynomial function has a real zero between 1 and 7.

To apply the Intermediate Value Theorem to the polynomial function f(x) = x^3 - x - 4 and show that it has a real zero between the integers 1 and 7, we need to verify that f(1) and f(7) have opposite signs.

Let's evaluate f(1) and f(7) to determine their signs:

f(1) = (1)^3 - (1) - 4 = 1 - 1 - 4 = -4

f(7) = (7)^3 - (7) - 4 = 343 - 7 - 4 = 332

From the calculations, we can see that f(1) = -4 and f(7) = 332.

Since f(1) is negative (-4) and f(7) is positive (332), they have opposite signs.

According to the Intermediate Value Theorem, if a continuous function changes sign between two points, then it must have at least one real zero between those points.

Since f(1) = -4 (negative) and f(7) = 332 (positive), the polynomial function f(x) = x^3 - x - 4 must have a real zero between the integers 1 and 7.

Therefore, we have demonstrated using the Intermediate Value Theorem that the polynomial function has a real zero between 1 and 7.

The probability of the person's waiting time being between 4 and 5 seconds, given that they have already waited for 3 seconds, is 0.20. Additionally, 15% of the time a person will wait at least 10.80 seconds before a wave crashes.

To determine the mean of the distribution, we use the given information that waves arrive every 6 seconds. This means that on average, a person can expect to wait for 6 seconds before a wave crashes.

The standard deviation is calculated as 0.00 seconds because the waves arrive with a fixed interval of 6 seconds, resulting in no variability in the waiting times.

To find the probability that the next wave will crash at least 1 second after the person arrives, we calculate the proportion of the 6-second interval after the person's arrival time. In this case, it is 1 second divided by 6 seconds, resulting in a probability of 0.17.

Given that the person has already been waiting for 3 seconds without a wave crashing in, we want to find the probability that their total waiting time will be between 4 and 5 seconds. We subtract the probability of waiting less than 4 seconds (3 seconds) from the probability of waiting less than 5 seconds (4 seconds) to obtain the desired probability of 0.20.

To determine the waiting time where a person will wait at least 15% of the time before a wave crashes, we find the corresponding value on the cumulative distribution function (CDF). By identifying the value on the CDF where the probability is 0.15, we can conclude that a person will wait at least 10.80 seconds before a wave crashes 15% of the time.

Answer: \(y^4\) + \(\frac{-73}{35}y^2\)- \(2\)

Step-by-step explanation:

Use FOIL:

\(y^4\) + \(\frac{-14}{5}y^2\) + \(\frac{5}{7}y^2\) + \(\frac{-70}{35}\)

Make  \(\frac{-14}{5}y^2\) and \(\frac{5}{7}y^2\) have the same numerator:

\(\frac{-14*7}{5*7}y^2 =\frac{-98}{35}y^2\)

\(\frac{5*5}{7*5} y^2=\frac{25}{35} y^2\)

Then add like terms and simplify:

\(y^4\) + \(\frac{-98}{35}y^2\) + \(\frac{25}{35} y^2\) + \(\frac{-70}{35}\)

\(y^4\) + \(\frac{-73}{35}y^2\)- \(2\)

The height of the hill for the given angle of elevation through which the given condition is satisfied is 460.1 ft

What about angle of elevation?

The angle of elevation is the angle between the horizontal plane and the line of sight or the direction of the observer's line of sight above the horizontal plane. It is measured upwards from the horizontal plane to the object being viewed. The angle of elevation is typically used in trigonometry and geometry to calculate the height, distance, or length of an object or location.

According to the given information:

Given, The given angle of elevation from point A to the top of a hill is \(49^{0}\).

As, we know tan (x) = \(\frac{perpendicular}{base}\)

tan \(49^{0}\) = \(\frac{unknown}{400}\)

The correct formula for the expression is,

Since, Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a function:

f(x) = a cos(bx + c) + d

Here a is the amplitude:

Since, The value of d is the average of maximum and minimum.

Hence,  d = (9 - 5)/2 = 4/2 = 2

And, The value of 'a' is the difference between the maximum value and d.

Hence,  a = -4 -(2) = - 6

Here, the half-period is,

A conditional equation is neither an identity nor a contradiction. It is a statement that is only true under certain conditions.

A conditional equation is an equation that expresses a condition. It has two parts: a hypothesis (or antecedent) and a conclusion (or consequent). The hypothesis states that a certain condition must be met in order for the conclusion to be true. For example, the equation "if x = 4, then x + 1 = 5" is a conditional equation. If the condition (x = 4) is true, then the conclusion (x + 1 = 5) is also true. However, if the condition is false, then the conclusion is also false. Therefore, a conditional equation is neither an identity nor a contradiction, but rather a statement that is only true under certain conditions.

The area inside the loop of the limacon given by r=7−14sinθ is 49π square units.

To find the area inside the loop of the limacon given by the polar equation r=7−14sinθ, we can use the following steps:

Find the points where the curve intersects the x-axis by setting r=0:

0 = 7 - 14sinθ

sinθ = 1/2

θ = π/6 or 11π/6

Find the limits of integration for θ by noting that the loop starts at θ=0 and ends at θ=2π:

θ limits: 0 ≤ θ ≤ 2π

Use the formula for the area of a polar region:

A = 1/2 ∫[a,b] r(θ)² dθ

where r(θ) is the polar equation and a and b are the limits of integration.

Rewrite the polar equation in terms of sinθ and cosθ:

r(θ) = 7 - 14sinθ

r(θ)² = (7 - 14sinθ)² = 49 - 196sinθ + 196sin²(θ)

= 196cos²(θ) - 196cos(θ) + 49

Substitute the limits of integration and evaluate the integral:

A = 1/2 ∫[0,2π] (196cos²(θ) - 196cos(θ) + 49) dθ

= 1/2 (98π)

Simplify the result to get the final answer:

A = 49π

The graph of y = 3x is a straight line that passes through the origin (0,0) and has a slope of 3.

In computer science, a graph is a collection of nodes or vertices, connected by edges or arcs, which represents a set of pairwise relationships between the nodes. Graphs are widely used in computer science and related fields as a way of representing complex networks or relationships between different entities.

Graphs can be directed or undirected. In a directed graph, each edge has a direction and represents a relationship between two nodes that is one-way. In an undirected graph, each edge represents a two-way relationship between two nodes.

Graphs can also be weighted or unweighted. In a weighted graph, each edge has a numerical weight assigned to it, which represents the strength or importance of the relationship between the two nodes it connects. In an unweighted graph, all edges have the same weight.

Graphs can be used to model a wide variety of systems and processes, including social networks, computer networks, transportation systems, and many others. They are also used in many algorithms and data structures, including shortest path algorithms, network flow algorithms, and data mining algorithms.
