If n is rational, it means that
Therefore when we do n² we can write it as
Remember that the product of two integer numbers is also an integer, therefore we can guarantee that
Then we can confirm that n² is the quotient of two integers and the denominator is not zero, therefore, n² is always rational, it cannot be an irrational number
Hey there!
The range of a function consists of all the y values the function has in its graph.
Notice in the graph your y values in the function range from 3 to infinity since the graph goes on infinitely upwards and then decreases to a steady y value of 3.
Therefore, your range in interval notation would be [3,∞) since the value of three is included.
Hope this helps and have a wonderful day! :)
357 I think is the right answer.Since the thermometer reading was 7°F greater than 350. The thermometer reading is 359+7=357
Answer:
A
Step-by-step explanation:
To find surface area of a cylinder, find the 2 circles which is the formula a=pi(r)^2, when you get that, multiply that by 2 because both sides count. Than the middle which I would imagine like a soda can. Cut a line right down the middle and hen you take it out, it looks like a Rectangle. Find the circumvented of the circle which would be pi(d)=circumfrence. Now after that you found the top side now the other side is 12 as shown here on the model and multiply thm together you’ll get 84 pi. Now those 2 circles would add up to 32 pi. Add them together youll get 116 pi. Now pi could be any but I’d Use 3.14 which will get you about to A becuase after all 3.14 is an approximate.
<span>Given
Situation:
=> There are 408 total of ticket sold for a school play
=> 3 times of the tickets are sold to students compare to the adults
=> So the ratio of the given situation is 1 : 3
=> Now, 1 + 3 = 4
Since, we need 4 parts, let’s divide 408 by 4
=> 408 / 4 = 102 – the number of tickets for adults
=> 102 x 3 = 306 – the number of tickets for students
=> 102 : 306</span>
