Answer:
Option d is right
Step-by-step explanation:
A function is called one to one if two x will not have same y value.
In other words, in the domain each x is matched with a unique y and if x1 not equals x2 we have the corresponding y1 will not be equal to y2.
In the graph given, we find that the y value say 1 has preimages in both to the right of y axis and to the left of y axis.
Hence this is not one to one.
This is a function because each x has a unique image. If we draw a vertical line in any part of the graph we find that it cuts only one time the graph of f(x)
Hence f is a function but not one to one. A one to one function need not pass through the origin.
Hence we find that of the options given, a,b and c are wrong.
But option d is right.
Answer:
127 ft
Step-by-step explanation:
split the square diagonally and use the pythagorean theorem
11. 9/20
12. 13/20
13. 12/20
that's if it doesn't have to be in percentage form
The answer is 403, just try simple long division.
Answer:
He can drive 481 miles if David rents his car for three days
Step-by-step explanation:
This is true because if you take the 24.95 and multiply it by 3, because he rented it for three days, you'll get 74.85. Then you'll subtract 200 (the total money that can be spent) by 74.85 you'll get 125.15. Divide the remaining number, 125.15 by 0.26 to get 481.34. Take the decimals away because you don't need it, if you want to be sure it's correct you can multiply 481 by 0.26 to get 125.05 which is lower than 125.15 so it good because if you use 482 besides 481 it will be higher than the amount of money David can spend, that's why 481 is the right answer.
