(i put a period after a imaginary number)
The expressions can be written as :a. log5.625 ≈ 0.75.
b. log6.4 + log6.12 ≈ 1.67.
c. log3.9^{4} ≈ 2.47.
What is logarithm function?
A logarithm function is a mathematical function that determines the power to which a fixed number, called the base, must be raised to produce a given value and The logarithm function is the inverse of the exponential function. The most commonly used base for logarithmic functions is 10 (log base 10), but other bases such as 2 (log base 2) and the natural logarithm base e (ln) are also used.
a. Since there is no base specified, we assume the base to be 10 by default. Therefore, we can write:
log5.625 = log(5625/1000)
Using the property log(a/b) = log(a) - log(b), we can simplify this expression to:
log5.625 = log(5625) - log(1000)
Using the change of base formula, we can convert the logs to a common base, such as 2 or e:
log5.625 = log(5625)/log(10) - log(1000)/log(10)
Evaluating the logs using a calculator or by simplifying, we get:
log5.625 ≈ 0.75
Therefore, log5.625 ≈ 0.75.
b. Using the property log(a) + log(b) = log(ab), we can simplify the expression:
log6.4 + log6.12 = log(6.4 × 6.12)
Using the change of base formula, we can convert this to a common base:
log6.4 + log6.12 = log(6.4 × 6.12)/log(10)
Evaluating the log using a calculator or by multiplying 6.4 and 6.12 and simplifying, we get:
log6.4 + log6.12 ≈ 1.67
Therefore, log6.4 + log6.12 ≈ 1.67.
c. Using the property log(a^{n}) = n log(a), we can simplify the expression:
log3.9^{4} = 4 log3.9
Using the change of base formula, we can convert this to a common base:
log3.9^{4} = 4 log(3.9)/log(10)
Evaluating the log using a calculator or by simplifying, we get:
log3.9^{4} ≈ 2.47
Therefore, log3.9^{4} ≈ 2.47.

Hodgman Honest is evaluating a new project for her firm, Basket Wonders (BW). She has determined that the after-tax cash flows for the project will be $10,000; $12,000; $15,000; $10,000; and $7,000, respectively, for each of the Years I through 5. The initial cash outlay will be $40.000. For this project, assume that it is independent of any other potential projects that Basket Wonders may undertake. The management of Basket Wonders has set a maximum PBP of 3.5 years for projects of this type. Required: Evaluate this project using payback period technique and advise the management accordingly.
Answer:
To calculate the payback period (PBP) for this project, we need to determine how long it will take for the initial cash outlay of $40,000 to be recovered from the after-tax cash flows.
Year 1 cash flow = $10,000
Year 2 cash flow = $12,000
Year 3 cash flow = $15,000
Year 4 cash flow = $10,000
Year 5 cash flow = $7,000
Total cash inflows for year 1 and year 2 = $10,000 + $12,000 = $22,000
Total cash inflows for year 3 = $15,000
Total cash inflows for year 4 = $10,000
Total cash inflows for year 5 = $7,000
Cumulative cash inflows for year 1 and year 2 = $22,000
Cumulative cash inflows for year 3 = $37,000
Cumulative cash inflows for year 4 = $47,000
Cumulative cash inflows for year 5 = $54,000
It can be seen that the cumulative cash inflows reach the initial cash outlay of $40,000 after year 2, and therefore the payback period for this project is 2 years. Since the payback period is less than the maximum PBP of 3.5 years set by management, this project can be considered acceptable.
So, Hodgman Honest should recommend that Basket Wonders should accept this project as it has a payback period of only 2 years, which is less than the maximum PBP of 3.5 years set by management.
Ricardo took out a single payment loan for $2500 at 7.8% ordinary interest to pay his federal income tax bill. Find the maturity value of the loan if he had to pay it back after 180 days.
Answer:
Therefore, the maturity value of the loan is $2568.75.
Step-by-step explanation:
To calculate the maturity value of the loan, we need to add the interest to the principal.
First, we need to find out how much interest Ricardo will owe for the 180-day period.
The formula for calculating ordinary interest is:
Interest = Principal x Rate x Time
where:
Principal = $2500
Rate = 7.8% = 0.078 (expressed as a decimal)
Time = 180/360 (since the interest is for a 180-day period and the rate is an annual rate)
Time is expressed as a fraction of a year because the rate is an annual rate. In this case, the time is 180/360 because the loan is for 180 days, which is half of a year.
Using the formula above, we can calculate the interest as follows:
Interest = $2500 x 0.078 x 180/360 = $68.75
Therefore, Ricardo will owe $68.75 in interest for the 180-day period.
To find the maturity value of the loan, we add the interest to the principal:
Maturity Value = Principal + Interest = $2500 + $68.75 = $2568.75
Therefore, the maturity value of the loan is $2568.75.

How to solve inequality?To solve an inequality, you need to find the set of values that make the inequality true. The process for solving an inequality depends on the type of inequality and the variables involved. Here are the general steps:
Determine the type of inequality: Is it a greater than (>), less than (<), greater than or equal to (≥), or less than or equal to (≤) inequality?Simplify both sides of the inequality as much as possible using algebraic operations such as addition, subtraction, multiplication, and division. Remember to apply the same operation to both sides of the inequality.If you multiplied or divided both sides of the inequality by a negative number, you need to reverse the direction of the inequality. For example, if you multiplied both sides of x < 3 by -1, you would get -x > -3.If there are variables on both sides of the inequality, move them all to one side of the inequality and simplify.If there are absolute values in the inequality, you may need to split the inequality into two separate cases, one for when the quantity inside the absolute value is positive, and one for when it is negative.Finally, express the solution as an interval of real numbers or as a set of values that make the inequality true. If the inequality is strict (> or <), use an open interval (e.g., (a, b)). If the inequality includes equality (≥ or ≤), use a closed interval (e.g., [a, b]).

What is square?
A square is a geometrical shape that has four equal sides and four equal angles of 90 degrees.
What is cone?
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a pointed top or apex. It looks like a funnel or an ice cream cone.
According to given information:When a plane intersects or slices through a cone, it creates a variety of different shapes depending on the angle of the plane and the position of the cone.
If the plane intersects the cone at an angle perpendicular to its base, it will create a circle. If the plane intersects the cone at an angle that is not perpendicular to its base, it will create an ellipse.
If the plane intersects the cone at an angle that is parallel to one of its generators (the lines that can be drawn from the vertex of the cone to any point on its base), it will create a parabola. If the plane intersects the cone at an angle that is not parallel to one of its generators, it will create a hyperbola.

A brick of mass 2 kg falls through water with an acceleration of 2 ms 2. The total force of the resistance is N.
The calculated value of the force of the resistance is 15.62 N
Calculate the force of the resistanceWe can use Newton's Second Law of Motion to solve this problem. The formula is:
F = m*a
where F is the net force, m is the mass of the object, and a is the acceleration.
In this case, the brick is falling through water, so there are two forces acting on it:
gravity (pulling it down) water resistance (slowing it down).The net force is the difference between these two forces:
F_net = F_gravity - F_resistance
The weight of the object is:
F_gravity = m*g
So, we have
F_gravity = 2 kg * 9.81 m/s^2 = 19.62 N
Now we can use the formula for net force to find the force of water resistance:
F_net = F_gravity - F_resistance
F_resistance = F_gravity - F_net
F_resistance = 19.62 N - m*a
This gives
F_resistance = 19.62 N - 2 kg * 2 m/s^2 = 15.62 N
Therefore, the force of water resistance is 15.62 N.

Option A correctly describes the area of the graph of the function.
How is an area of the graph calculated?
The area of a graph is the area under the function curve enclosed within the X-axis of the graph. Thus, it is the area of the figure formed by enclosing the function graph with the X-axis.
It is the integration of the function polynomial of the possible values of x that the function curve lies in.
Here the function equation is : [tex]f(x) = ( 25 - x^{2} )[/tex]
From the figure, we can see that the value of x varies from -5 to 5.
Initial x-value of integration = minimum value of x
= -5
Final x-value of integration = maximum value of x
= 5
Thus, the area of the graph can be correctly calculated as. :
[tex]Area = \int\limits^{maxX}_ {minX} \, f(x)dx[/tex]
[tex]Area = \int\limits^5_ {-5} \, (25-x^{2} )dx[/tex]

The diameter of the base of a cone is shown on the grid. Each square unit on the grid has a side length of 1 foot. The volume of the cone is approximately 200.96 cubic feet. Determine the height of the cone, and construct it vertically on the grid with respect to the center of the cone's base.
Use 3.14 for .
Answer:
First, we need to find the radius of the base of the cone. We can see from the grid that the diameter is 8 units, so the radius is 4 units (or 4 feet).
Next, we can use the formula for the volume of a cone to find the height:
V = (1/3)πr^2h
Substituting the given volume and radius, and using 3.14 for π, we get:
200.96 = (1/3) x 3.14 x 4^2 x h
Simplifying and solving for h, we get:
h = 200.96 / (1/3 x 3.14 x 4^2)
h = 200.96 / 53.02
h ≈ 3.79 feet (rounded to two decimal places)
To construct the cone vertically on the grid with respect to the center of the base, we can draw a circle with radius 4 units (or 4 feet) centered at the point (4,4) on the grid. Then, we can draw a line from the center of the circle (point (4,4)) up to a point above the circle that is 3.79 units (or 3.79 feet) away from the center. This line represents the height of the cone. Finally, we can connect the endpoint of the line to the points where the circle intersects the grid to complete the cone.

The correct answer is E (-1,-3). Reflection across the x-axis is a transformation that flips the object across an imaginary line that runs through the center of the x-axis.
What is transformation?Transformation in mathematics is the process of changing an object or figure in some way. This includes changing the size, position, rotation or reflection of an object. Transformations can also be used to move a figure from one coordinate system to another. Common transformations include translation, rotation, reflection and scaling.
In this case, the x-axis is the line y = 0. The figure ABCD is reflected across this line, resulting in point A being reflected to E.
When a figure is reflected, the x-coordinates remain the same, while the y-coordinates change sign. This means that the x-coordinate of point A (-1) remains the same, but the y-coordinate (3) changes to its opposite (-3). Therefore, the resulting coordinates of point A are (-1,-3).
Reflection across the x-axis is an example of a transformation. Transformations involve changing the position, size or orientation of a figure, but not its shape. This means that the figure ABCD is still the same shape after being reflected, but its position has changed. After being reflected, the figure is now located on the opposite side of the x-axis.

What is fraction ?
A fraction is a way of representing a part of a whole or a ratio between two quantities. It is written in the form of a numerator and a denominator separated by a horizontal line. The numerator represents the number of equal parts under consideration, while the denominator represents the total number of equal parts that make up the whole. For example, the fraction 3/4 represents three equal parts out of a total of four equal parts. Fractions can be added, subtracted, multiplied, and divided to perform various mathematical operations.
According to the question:
The given fractions can be added if they have a common denominator. In this case, the common denominator is 9x.
So, we need to write the fractions with 9x as the denominator:
2/1 * (9x/9x) = 18x/9x
10/1 * (9/9x) = 90/9x

Let the unknown number Ann thought of = n
(n × 5) + 7 = r
5n + 7 = r
If Jim is given Ann's number n if given the results, r
This means Jim will make Ann's number n the subject of the formula;
5n + 7 = r
Subtract 7 from both sides
5n = r - 7
divide both sides by 5
n = (r - 7) / 5
Therefore, the formula written in terms of n is n = (r - 7) / 5
