In the set of real numbers, what is the domain of #f (x ... - Socratic
The domain, or allowed values of x, is x>=-5. In interval notation, the domain is [-5,oo). For real numbers, the expression under the square root must be greater than or equal to zero.
Question #2872d + Example - Socratic
A rank-m tensor is a mathematical object that represents N^m real numbers, where N is the dimension of space. rank-0 Tensor: represents a single real number and is usually called a scalar. Examples of rank-0 tensors (scalars) are temperature, density etc. rank-1 Tensor: represents N real numbers and is usually called vectors. Examples of rank-1 tensor (vector) are velocity, force, etc. rank-2 ...
What is the range of 20x+4? - Socratic
Because there are no restrictions on the value of x AND because this is a linear transformation: The Range is the set of all Real Numbers or {RR}
Question #5aa42 - Socratic
See explanation. Between any 2 real numbers there are infinitely many other numbers. To find such numbers you can do the following: Find the common denominator: 1/5=3/15; 1/3=5/15 The number between them is: 4/15
Question #b8278 - Socratic
Basically the same as we do with the real numbers. Perhaps if we rewrite this as: (3+2i)* (1-3i) then we mulitply 3 from the first paranthesis with the both constituents from the second. We do the same thing for the second constituent from the first paranthesis.
If sum_ (n=1)^oo abs (a_ (n+1)-a_n) converges then does the sequence a ...
So if the set of numbers is closed under Cauchy sequences then the limit exists. Such is true of the set of Real numbers, so the assertion that a_n converges is true. Footnote If the set of numbers we were dealing with was the rational numbers QQ, then the condition that: sum_ (n=1)^oo abs (a_ (n+1)-a_n)" " converges is not sufficient.
Question #4c938 - Socratic
Log of a negative number is undefined. There is no solution for this in real numbers. To solve it you would have to deal with complex numbers.
Question #eb249 + Example - Socratic
In mathematics, we would say that x could be all real numbers, or for short, x in RR. Range: This isn't the same as domain. Notice that the curve only goes from -1/2 to +1/2. If you tried to find a point on the curve where the y-value was 2, for example, you couldn't do it, because 2 is outside the function's range.

List all of the the restricted values sqrt 2x - 5? - Socratic
I wrote the form" " hash sqrt (2x - 5) hash" " to get sqrt (2x-5) For the numbers to stay a belong to the set of 'Real numbers' you need to make sure that 2x-5 >=0 2x-5>=0 add 5 to both sides 2x>=5 divide both sides by 2 x>=5/2 So the restricted value are all those that do not comply with x>=5/2 and these are x<5/2
