The weight of an African elephant is 6x10^6 grams; the weight of a tiger is 3x10^5 grams. How many times heavier is the elephant than the tiger?
Answers
elephant= x times tiger
6 times 10^6=x times 3 times 10^5
divide both sides by (3 times 10^5)
remember that (x^m)/(x^n)=x^(m-n)
so
(6 times 10^6)/(3 times 10^5)=x
(6/3) times (10^6)/(10^5)=x
2 times 10^1=x
2 times 10=x
that would be 2 times 10^1 or 20 times
An acrobat of mass m slides down a vertical rope of height h. For the first three quarter of her descent she grips the rope with her hands and legs so as to produce a fictional force equal to five-ninth of her weight.she then tighten her grip so that she comes to rest at the bottom of the rope. Sketch a (t .v) graph to illustrate her descent
Answers
The acrobat's descent on a time versus velocity graph would show an initial linear increase in velocity due to gravity minus frictional force, followed by a sharp negative slope as she comes to a stop at the bottom.
The acrobat's descent can be analyzed by plotting a time (t) versus velocity (v) graph. Initially, the acrobat experiences a frictional force equal to five-ninths of her weight, which creates constant deceleration. For the first three quarters of the descent, her velocity will increase linearly (assuming constant deceleration) until she tightens her grip, which will cause a sharp decrease in velocity until she comes to a complete stop at the bottom. The graph would show a slope that decreases in magnitude over time and then drops to zero when the acrobat comes to rest.
Example Graph Description:The graph starts at the origin (0,0), indicating that the descent starts from rest.As time progresses, the velocity increases linearly due to the effect of gravity partially opposed by frictional force.Before reaching the bottom, the acrobat applies enough force to stop, leading to a sharp negative slope on the graph that touches the t-axis, indicating a stop.Can someone help me in graphing

Rational exponent is an exponent that is fractional in form. Let us dissect this one by one.
An n root means that the number or the variable has a power raised 1 / n. For example, if we have a square root of x, this means that x^(1/2).
So in this case since this is cube root, therefore our total variable is raised to the power of 1 / 3.
Since it is also raised to the power of 5, therefore the total power is 5 / 3. This makes the variable in the form:
(x^4)^(5 / 3)
To simplify this further, our variable x is raised also to the power of 4, therefore we multiply the powers. Which simplify this further into:
x^20 / 3

Why is expected income a large factor in choosing a retirement plan
Answers
Expected income is crucial in choosing a retirement plan because it influences permanent income for savings, the adequacy of funds against inflation, and financial security post-retirement.
Choosing a retirement plan is a vital financial decision; expected income plays a large role because it directly affects a person's ability to save and sustains their lifestyle after they retire. The idea of permanent income, which is the average annual income an individual expects to receive for the rest of their lives, influences how much they allocate to retirement savings. It's crucial for asset accumulation and ensuring financial security.
Retirement funds sourced from plans like private company pensions or defined benefits can be fixed and may not keep up with inflation, leading to a potential loss of purchasing power over time. Therefore, understanding one's expected income helps in selecting retirement plans that can adjust and possibly increase over time to hedge against inflation. Additionally, individuals must consider the impact of future income changes on their current saving and consumption patterns.
Behavioral economics factors in human psychology and behavior, suggesting that individuals may not always make rational financial decisions due to a lack of self-control or understanding of long-term benefits, influencing retirement plan choices. Thus, expected income is a significant consideration for individuals when choosing a retirement plan, as it determines their ability to save enough to maintain their desired lifestyle in retirement.

A cell phone company wants to place a new cell tower so that it is the same distance from the centers of the three towns. How can the company find where to place the tower? Explain.
Answers
The company can find where to place the tower by determining the point of concurrency of these three (3) towns.
What is a triangle?A triangle refers to a two-dimensional shape that is typically made up of three (3) sides, three (3) vertices and three (3) angles. This ultimately implies that, a polygon that has three (3) lengths of sides is a triangle.
What is a point of concurrency?A point of concurrency can be defined as a single point that is shared by three (3) or more lines, segments, rays, or planes. Thus, a triangle is considered to be concurrent when at least three (3) lines intersect at a single point.
Based on geometry, the point (circumcenter) that is equidistant from the vertices of the triangular tower would be equal in distance from each of the centers of these three (3) towns.Generally, the circumcenter of a triangle can easily be determined by constructing the point of concurrency of the perpendicular bisectors of a triangle.In conclusion, the company can find where to place the tower by determining the point of concurrency of these three (3) towns, so that they all have the same distance from the centers.

Answer:
For the tower to be the same distance from each of the centers, the company must find the point that is equidistant from the vertices of the triangle. This is the circumcenter of the triangle and can be found by constructing the point of concurrency of the perpendicular bisectors of the triangle.
The tower needs to be equidistant from the vertices of the triangle.
The tower should be placed at the circumcenter of the triangle.
To find the circumcenter, find the intersection point of the three perpendicular bisectors of the triangle.

How to find the distance between a point and a line
Answers
Final answer:
To find the distance between a point and a line, you need to find the equation of the line, find the coordinates of the point, substitute the coordinates into the equation, and calculate the perpendicular distance.
Explanation:
To find the distance between a point and a line, you need to use the formula for the distance from a point to a line. Here are the steps:
First, find the equation of the line.
Next, find the coordinates of the given point.
Substitute the coordinates of the point into the equation of the line to find the perpendicular distance from the point to the line.
The distance between the point and the line is the perpendicular distance found in step 3.
For example, let's say the equation of the line is y = 2x + 3, and the coordinates of the point are (4,5). To find the distance between the point and the line:
The equation of the line is y = 2x + 3.
The coordinates of the point are (4,5).
Substituting the coordinates (4,5) into the equation y = 2x + 3 gives 5 = 2(4) + 3, which simplifies to 5 = 11.
The perpendicular distance from the point to the line is |5 - 11|, which is equal to 6.
Therefore, the distance between the point (4,5) and the line y = 2x + 3 is 6 units.

To solve the equation -2x^2 + 3x - 9 = 0, we can use the quadratic formula. This equation does not have any real solutions, but it has complex solutions involving imaginary numbers.
Explanation:To solve the equation -2x^2 + 3x - 9 = 0, we can use the quadratic formula. Substituting the values a = -2, b = 3, and c = -9 into the formula, we can then simplify to find the solutions for x.
The quadratic formula is given by:
x = (-b ± sqrt(b^2 - 4ac)) / (2a)
Substituting the values, we have:
x = (-3 ± sqrt(3^2 - 4(-2)(-9))) / (2(-2))
Simplifying further, we get:
x = (-3 ± sqrt(9 - 72)) / -4
x = (-3 ± sqrt(-63)) / -4
Since the square root of a negative number is not a real number, this equation does not have any real solutions. The equation has complex solutions, which involve the use of imaginary numbers.
