Why can a problem with extra information be difficult to solve?

Mathematics

Leni [432]3 years ago

The problems with extra information, are difficult to solve because sometimes, not all data should be used.

Therefore, students begin to doubt the fact that they are not using all the information raised in the problem.


Example:


Problem:

Suppose we have a triangle with a right angle. The problem gives us as data an angle and the sides of the triangle. We want to determine the length of the hypotenuse.

Solution:

Using the Pythagorean theorem we can solve the problem.

The given angle data is an extra information that you should not use for this case.

Let the universal set be the set of integers and let A = {x | x^2 ≤ 5}. Write A using the roster method.
Zarrin [17]

Answer:

Step-by-step explanation:

Given that Z the set of integers is the universal set and

A is given in set builder form.

A = {x | x^2 ≤ 5}

To convert this into roster form, we can find solutions for x

When x^2\leq 5\\|x|\leq \sqrt{5} =2.236

i.e. all integers lying between -2.236 and 2.236

The only integers satisfying this conditions are

-2,-1,0,1,2

Hence A in roster form is

A={-2,-1,0,1,2}

Drag each tile to the correct location. Each tile can be used more than once, but not all tiles will be used.
AysviL [449]

Answer:

y=770-55x --- given

y - 770 = 770 - 55x - 770 ----subtraction property of equality

y = -55x + 770 ---Simplification

y-770/-55 = -55x/-55 --- Division property of equality

-y-770/55=x---Simplification
