    Is there a way to simplify finding the minimum distance between two objects approach?

    The problem is as follows: Two buggies one orange and the other blue are passing through an intersection with constants speeds of $v_{orange}=6\,\frac{m}{s}$ and $v_{blue}=6\sqrt{3}\,\frac{m}{s}$ respectively. Find the minimum approach in meters between the orange and blue buggies. The...

    Finding the Zeros of This Function

    Hi, Any ideas on how to algebraically find the zeros of this function? f(x) = 0.0002x^3 - 0.08x^2 - 5,000 I can graph the function and see that it has a zero at x = 500, however, how can I analytically solve for that value? Is there a trick to factoring a polynomial like this?

    What is the use of finding time ratio in this problem?

    Dipak goes to his office, covering half of the distance by auto & rest by metro; total time taken by him to cover complete distance is 50 min. If he covers complete distance by metro, it would take 35 mins to reach the office. On a particular day, he goes to his office & returns by auto; find...

    Finding approximately the greatest possible percentage error

    A swamp interferes with the direct measurement of a surveyline AB. Hence, an auxiliary point C is established and the distance AC is measured with an accuracy of 1 part in 1000. Then the angles BAC and ABC are found to be 45 and 30 degrees respectively, with a possible error of 2 minutes in...

    Finding square root of matrix without eigenvector

    A is a 2x2 matrix. (0 -2) (2 0) Find the square root of this matrix. I managed to find one of the square root, because I know A is a 90-degree anti-clockwise rotation stretched by a factor of 2. So I just have to "half" that operation and I get (1 -1) (1 1) However, there...

    Finding Values of the Mean using Static Values with only Means - What is the formula?

    Hey, So I have a question about finding values that make up an average. In the example below each number is an average of three values. in the example below I will explain how the averages are made up. As you can see each A - M is a given mean of three values. The last two values in the mean...

    Finding the absolute extrema problem

    So, this one is more challenging for me to do, since I normally work with equations/functions without sin or pi involved. The problem:y =2sin^(2)x over [-pi/6,pi/3]. How am I suppose to find the absolute extrema with sin and pi involved? Please show steps on how to do so.

    Finding exact value of the sum of two inverses

    Hi, From my textbook, I have an example saying: cos(arcsec(3) + arctan(2)) = (√5 − 4√10)/15 :unsure: Why is it so? If anyone would want to explain, I would be very grateful. If this had been angles, I could recognize, ex: cos(arcsec(2) + arctan(1)) I would have used the sum identity...
