If a loan is taken out for $278 at 10% and costs the borrower $174.12 in simple interest, how many years was the loan for? ROUND YOUR ANSWER TO THE NEAREST WHOLE YEAR
Answers
Data:
Loan=$278 at 10%
A simple interest is calculated for payments on the initial capital.
If the total interest was $174.12.
If the interest is on a year. You calculated the interes of one year. The 10% of $278:
\(278\cdot\frac{10}{100}=27.8\)In a year the interest is $27.8.
Then, $174.12 divided into $27.8 is the number of years of the loan:

historical data shows that with 68% confidence we can finish a task that follows a normal distribution between 81 and 85 days. what is the standard deviation of the duration of this task?
Answers
The standard deviation of the duration of this task is 4 days
To determine the standard deviation of the duration of the task, we can use the information about the confidence interval and the properties of the normal distribution.
In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. Since the confidence interval provided (81 to 85 days) represents the range within one standard deviation from the mean, we can find the standard deviation by calculating the range between the upper and lower limits of the confidence interval.
The range of the confidence interval is given by:
Range = Upper Limit - Lower Limit
= 85 - 81
= 4
Since this range corresponds to one standard deviation, the standard deviation of the duration of the task is also 4 days.
Therefore, the standard deviation of the duration of this task is 4 days.

P =(-180i + 60j + 80k), the distance between A and O is 10m. solve for rOA
Answers
The vector rOA is approximately -0.048i + 0.024j + 0.039k. This represents the position of point A relative to the origin O when the distance between them is 10m.
To solve for rOA, the distance between point A and the origin O, given vector P = (-180i + 60j + 80k) and a distance of 10m, we need to find the magnitude of vector P and scale it by the distance.
The vector P represents the position of point A relative to the origin O. To find the magnitude of vector P, we use the formula:
|P| = \(\sqrt{((-180)^2 + 60^2 + 80^2)}\)
Calculating this, we get |P| = √(32400 + 3600 + 6400) = √(42400) ≈ 205.96
Now, to find rOA, we scale the vector P by the distance of 10m. This can be done by multiplying each component of vector P by the distance and dividing by the magnitude:
rOA = (10/|P|) * P
= (10/205.96) * (-180i + 60j + 80k)
≈ (-0.048i + 0.024j + 0.039k)
Therefore, the vector rOA is approximately -0.048i + 0.024j + 0.039k. This represents the position of point A relative to the origin O when the distance between them is 10m.

se polar coordinates to find the volume of the solid below the cone z=x^2 y^2 and above the ring 1 x^2y≤
Answers
The volume of the solid below the cone z = x²y² and above the ring 1 ≤ x² + y² ≤ 4 in polar coordinates is (64π/15).
To find the volume of the solid, we integrate the function representing the cone over the region defined by the ring in polar coordinates.
In polar coordinates, the cone equation z = x²y² can be expressed as z = r²cos²(θ)sin²(θ), where r represents the radial distance and θ represents the angle.
The region defined by the ring can be expressed as 1 ≤ r² ≤ 4.
To find the volume, we integrate the function z = r²cos²(θ)sin²(θ) over the region of the ring in polar coordinates.
V = ∫∫∫ r²cos²(θ)sin²(θ) r dr dθ
= ∫[0,2π] ∫[1,2] r³cos²(θ)sin²(θ) dr dθ
= ∫[0,2π] ∫[1,2] r³(cos²(θ))(sin²(θ)) dr dθ
= ∫[0,2π] ∫[1,2] r³cos²(θ)sin²(θ) dr dθ
To evaluate this integral, we can use the property cos²(θ)sin²(θ) = (1/4)sin²(2θ), so the integral becomes:
V = (1/4) ∫[0,2π] ∫[1,2] r³sin²(2θ) dr dθ
Now, we integrate with respect to r:
V = (1/4) ∫[0,2π] [(1/4)r⁴sin²(2θ)] [1,2] dθ
= (1/4) ∫[0,2π] [(1/4)(2⁴ - 1⁴)sin²(2θ)] dθ
= (1/4) ∫[0,2π] [(15/4)sin²(2θ)] dθ
= (15/16) ∫[0,2π] [1 - cos(4θ)]/2 dθ
= (15/32) [θ - (1/4)sin(4θ)] [0,2π]
= (15/32) [2π - (1/4)sin(8π) - 0 + (1/4)sin(0)]
= (15/32) (2π - 0)
= 15π/16

A system of two linear equations in two variables has no solution. What statement is accurate about these two linear equations?

The two linear equations do not cross the x-axis.

The two linear equations do not cross the y-axis.
The two linear equations intersect at exactly one point.
Answers
The right response is that the two linear equation never intersect , because the graph of these two linear equation will be two parallel lines.
How many types of solution are there for two linear equations ?
There are 2 types of solution :
Consistent :
A consistent system is said to be an independent system if it has a single solution.
A consistent system is said to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide, so the equations represent the same line. Each point on the line represents a pair of coordinates that fits the system. So there are an infinite number of solutions.
Non-consistent :
Another type of system of linear equations is the inconsistent system, in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no common points for both lines; therefore, there is no solution to the system and if we draw the graph of these equations then the graphs of both equation becomes parallel to each other.

The two linear equations never intersect.
When a system of two linear equations in two variables has no solution, it means that there is no set of values for the variables that satisfies both equations simultaneously. Geometrically, this corresponds to the two lines represented by the equations being parallel. Since parallel lines never intersect, the statement "The two linear equations never intersect" accurately describes the situation.
If the two linear equations were graphed on a coordinate plane, they would appear as two distinct lines that run parallel to each other without ever crossing or intersecting. This indicates that there is no common point of intersection between the lines, and therefore no solution exists for the system of equations.
It is important to note that this scenario is different from the case where the two linear equations represent the same line. In that case, the equations would be equivalent, and every point on the line would satisfy both equations. However, when there is no solution, it means that the lines do not share any common points and never intersect.

The percent of the field goals did Samuel make will be 77.5%.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

A Voronoi diagram is a division of a plane into areas near each of a given set of objects in mathematics. These things are just infinitely many points in the plane in the simplest scenario (called seeds, sites, or generators). There is a region, known as a Voronoi cell, for each seed that is made up of all points in the plane that are closer to that seed than to any other point. A set of points' Voronoi diagram and Delaunay triangulation are identical.
We are aware that any intersection of half-planes results in a convex region bordered by a collection of linked line segments. Voronoi edges are the line segments that define the limits of Voronoi regions. These edges' termini are known as Voronoi vertices.

• Centre = (0,0)
Finding distance between the two points :-
