Question

The difference between the squares of two numbers is 8.

Twice the square of the first number increased by the square of the second number is 19.

Find the numbers.

Answer #1

We can let number as x and y.

So difference of their square is 8.

So we can write:

.........................................(i)

We can write second equation as:

From equation (i)

From equation (i) we have:

So numbers are and

Suppose two estimators of a parameter are both unbiased, but the
first estimator has twice the variance of the second. Then the
ratio of the mean square errors of the estimators is given by
(first/second): __________________.

The sum of three numbers is 30. One of the numbers is 5 more
than twice a second number and 5 less than the third number. What
are the numbers?

One
gram of wheat on the first of 64 squares of a chess board . On the
second square two grams of wheat , on the third square four grams
of wheat , on the fourth square eight grams of wheat , the amount
doubled for each remaining square, how many grains of wheat should
be placed on square 14 ? Also the total number of grains of wheat
on the board at the time and their total weight in...

How could I mathematically prove these statements?
1.If the difference of two numbers is even then so is their
sum.
2. If a sum of several numbers is odd, then at least one of the
numbers is itself odd.
3. If a square number is even then so is its square root.

Using a) a difference of squares and b) a perfect square
trinomial; Explain in details the pattern that allows
one to recognize the binomial or trinomial as having special
factors. Illustrate with examples of a binomial or trinomial
expression that may be factored using the special techniques you
are explaining.

Find three positive numbers whose sum is 12, and whose sum of
squares is as small as possible, (a) using Lagrange multipliers
b)using critical numbers and the second derivative test.

Consider a gameboard that has 9x9=81 squares. You put one grain of
sand on the first square of the gameboard, two grains on the second
square, four grains on the third square, continuing until you have
filled the board. Compute the total number of grains needed to do
this to see why the task, seeming simple, can not be completed.
A. 1.21 x 10^24 grains of sand
B. 2.42 x 10^24 grains of sand
C. 1.00 x 10^6 grains of...
