Answer:
290
Step-by-step explanation:
first you multiply 27 times 13 and get 351.you then subtract 351 from 61 and get 290.
Answer: Choice A
Note: the range should be
. See explanation below.
===================================================
We can plug in any real number for x to get some output for y. The domain is the set of all real numbers in which we say
which is interval notation. It represents the interval from negative infinity to positive infinity.
The range is the set of possible outputs. The smallest output possible is y = -5 which occurs at the vertex (3,-5). We can get this y value or larger. So we can describe the range as the set of y values such that
and that translates to the interval notation
.
The square bracket says "include this endpoint" while the curved parenthesis says to exclude the endpoint. Your teacher mistakenly wrote
for choice A, when they should have written 
I think either your teacher made a typo or somehow the formatting messed up. Either way, choice A is the closest to the answer.
Answer
Basically you need to know how many hours to work then I think it would help your problem.
Step-by-step explanation:
Answer:
{x∈R |
, x∉Z}
Step-by-step explanation:
Given the function y=3tan(2/3x)
We know that tangent is a function that's continuous within it's domain but not continuous on all real numbers
Also, the roots of y=3tan(2/3x) is
where n is an integer
Note that the domain of the function cannot be within 
Therefore, {x∈R |
, x∉Z}
Roughly 24, but there's possibly like nine more. I got 24 without getting too confused
