Create a class called 'Triangle' with the following member

functions (public) and variables (private).

Variables -- 3 lengths -- all 3 values are floats.

1 bool -- tells if current lengths are valid.

Functions --

Constructor with no arguments (default constructor) -- asks user for

3 values and verifies they are valid. (all 3 > 0, sum of any 2

greater than the 3rd.) Keeps asking until it gets valid values.

Constructor with 3 lengths -- (3 arguments).

These can be used to "set" values from within a function.

It needs to verify the values are legitimate (all 3 > 0, sum

of any 2 greater than the 3rd.) Stores them even if they are

invalid (stores false in bool argument in this case.)

GetTriangle -- "returns" the 3 lengths and boolean value.

Perimeter -- returns the sum (float) of the 3 sides.

Equilateral -- returns if the triangle is/isn't equilateral (bool)

Right -- returns if the triangle is/isn't right (bool)

(overloaded) == operator to test if 2 triangles are similar in size.

Write the classes functions/constructors.

Also write a main function to test the above.

Choose data to run with that will test at least the following:

1) Invalid values (e.g. -1 3 4 and 3 4 8)

2) An equilateral triangle

3) A right triangle

4) A triangle that is neither right nor equilateral

5) 2 identical triangles

6) 2 similar, but different triangles

7) 2 non-similar trianglesHey guyz

Write a program to implement the bisection method, and use it to find a

solution of various equations, to be given to you by your TA. Each equation

will be of the form

ax^n + bx^n-1 + cx^n-2 + .... fx^2 + gx^1 + hx^0 = 0

where the coefficients a,b, etc may be +, -, or 0.

Write the program to accept an equation where the coefficients and exponents

are given by the user a pair at a time, and can have as few as one pair and as

many pairs as they like (up to, say 10.) Store these in a 2-dimensional array

(one row for the coefficients, another for the corresponding exponents.)

Get the array (and the starting points) with a GetData function.

Then pass the array (and a counter for the number of terms) to another

function called Bisect (also pass to it the starting points to evaluate).

This function should calculate the x-value that makes the function evaluate

to approximately zero (your TA will tell you to what tolerance to check)

and will get that value back (along with it's corresponding y-value)

to the main function.

Hey guyz I need help with "Engineering Mechanics Statics" I have assignments due tomorrow. I tried a lot but as I don't know much so I am unable to do it. I can't upload my assignment here, So I recommend you to chat with me & explain me. If any one who is really a master in it can do it then that would be a really great help.

Thank You in Advance!

Q-1) given the vectors in standard position vector v=(5,1) & vector w=(1,3). find the angle between them. then find the parallel & orthogonal components of vector v with respect to vector w.

Q-2) Given the complex number z = sqrt(3) + 3i, write it in trignometric form. determine z^5 & sqrt(z)

Thank You very much for help in advance!!

Q-1) A ship is moving due west at 8 knots. You are in a speed boat \sqrt{2} nautical miles directly southeast of the ship. (Thus your bearing as seen from the ship is 135 degrees.) You need to catch up with the ship, and you can move at a speed of 16 knots. So you take off at a bearing of _____ degrees, and you reach the ship in______ minutes. Enter your answers as decimal expression with at least four digits, or enter mathematical expressions.

Q-2) A flagpole at right angle to the horizontal is located on a slope that makes an angle of 12deg with the horizontal. The pole's shadow is 16 meters long and points directly {\it down} the slope. The angle of elevation from the tip of the shadow to the sun is 20deg. The height of the pole is _____ meters.

solve for x

(5)^(-x/2) = 1/5

Thanks for your help!!

You are driving at a constant speed of sixty miles per hour along a straight road going north. You see a prominent peak at a bearing of 45 degrees, and you know that that peak is 10 miles east of the road. At this time your distance from the peak is 14.1422 miles. Five minutes later you see the peak at a bearing of ______ degrees. After another five minutes the peak is due east of you. At that precise spot there is a historical marker that tells you about the peak. 7 minutes after you pass the marker the peak is at a bearing of ________ degrees. You sit back in your car and reflect on the pleasant fact that the trigonometry class you are taking makes it possible for you to figure out that t minutes after you pass the historical marker the bearing of the peak is _______ degrees. (Enter a mathematical expression involving the variable t.)

Thank You in advance

You are on a stationary fishing boat, and you send out your life boat to retrieve some gear. The boat moves one nautical mile east, and then 1.5 nautical miles northeast. Then it stops. You can see the boat at a bearing of _______ degrees and at a distance of ______ nautical miles.

Hint: Draw a picture. Consider two right triangles. Apply the Pythagorean Theorem and an inverse trig function.

Thank You very much in Advance

You are hiking north along the west shore of a river that's flowing due north. You notice a tree on the far shore at a bearing of 30 degrees. You walk on for another 100 feet and you are stopped by an unclimbable cliff. You contemplate swimming across the river and wonder how wide it is. The tree on the other side now appears at a bearing of 45 degrees. Remembering your trig class, you figure out that the river is ________ feet wide.

Thanks in Advance.

question 1 - Suppose you are entertaining two different job offers. Job A has a

starting salary of $20,000 and assures you of a raise of $1,000 per year. Job

B offers you a starting salary of $23,000, with a yearly raise of $725. Which

job will pay you more over the first ten years? How much more?

Question 2 - The government plans to cut taxes by $100 billion. They expect that

people will spend 95% of every dollar they receive. How much spending does

the government expect to create with its tax cut?

it is widely accepted that at the center of every active galaxy lurks a super massive black hole consuming whole stars at a time. What is the evidence of that?

All quasars exhibit large redshifts in their spectrum. (a) What does this means about their motion relative to us? (b) What does this mean about the distance of quasars? (explain) (c) Why do we think that quasars are now extinct?

Describe the process through which a quasar becomes an active galaxy & subsequently a normal galaxy. What happens to its energy output throughout these stages?

a) Name two ways that astronomers use to distinguish active galaxies from normal ones. (b) Why do active galaxies emit large amount of radio & infrared but less visible light?

2) All quasars exhibit large redshifts in their spectrum. (a) What does this means about their motion relative to us? (b) What does this mean about the distance of quasars?

(e) Why do quasars eventually become much less luminous & at first become active galaxies & later on normal galaxies?

It has been observed that the cosmic background radiation is not exactly isotropic (same in every direction) but has a tiny redshift when observed at one side of the Earth & an equal blueshift at the other. What does this mean?
