Answer:
Use multitape Turing machine to simulate doubly infinite one
Explanation:
It is obvious that Turing machine with doubly infinite tape can simulate ordinary TM. For the other direction, note that 2-tape Turing machine is essentially itself a Turing machine with doubly (double) infinite tape. When it reaches the left-hand side end of first tape, it switches to the second one, and vice versa.
The answer is B. 6m^3n^5. Hope I actually helped!
This question is very oddly worded. The domain is the set of x-values, but this is a set of (x,y) ordered pairs.
I'm reading this question as "Here's a function, { (1,5), (2,1), (-1,-7) }. If this is reflected over the x-axis, what's the range?"
Assuming that is the question that is meant to be asked, reflecting a function over the x-axis will just change the signs of the y-values.
(1,5) -> (1,–5)
(2,1) -> (2,–1)
(-1,-7) -> (-1,+7)
I'd pick the third option.
Answer:
The whole tank cost $55.13
Step-by-step explanation:
All you have to do is multiply the fraction and cost, to ge thte total cost
15 3/4 also equals 15.75 (it will be easier to multiply two fractions)
now each gall of the 15.75 costs 3.50 so we multiply the number of gallons by the cost
15.75 x 3.50 = 55.125
but now we must round since there isnt .125 cents
so
55.13 is the cost
