Answer:
10
Step-by-step explanation:
f(x) = 3x + 1
f^-1 = x-1/3 , it is known as inverse function.
f(3)= 3*3 +1
=9+1
=10
To find inverse,
x=3x + 1
y=3x+1
Exchanging the position or x and y
x=3y+1
x-1=3y
.•. y=x-1/3
Answer:
Ron runs the fastest.
Step-by-step explanation:
To see who's the fastest you should convert everyone's speed into one unit (feet per second for this example).
Liz
13 feet per second (doesn't have to be converted).
Ron
He runs 495 feet in 34 seconds, so he runs 495 feet ÷ 34 ≅ 14.55882 feet per second.
Katie
1 mile = 5280 feet. She runs 5280 feet in 506 seconds, so she runs 5280 ÷ 506 ≅ 10.43478 feet per second.
Will
1 minute = 60 seconds. He runs 666 feet in 60 seconds, so he runs 666 ÷ 60 = 11.1 feet per second.
Results
Liz - 13 feet per second
Ron - 14.55882 feet per second
Katie - 10.43478 feet per second
Will - 11.1 feet per second
As the results show, Ron runs the fastest, Liz the second fastest, Will the third fastest and Katie the fourth fastest.
Answer:10 and 11
Step-by-step explanation: Sqrt 100 is 10, sqrt 121 is 11, so sqrt 110 must be somewhere in between
Find the difference between consecutive terms. If all of them in the sequence have the same difference, then it's an arithmetic sequence. The fourth answer, for example, is not an arithmetic sequence. The difference of 14 and 4 is 10 since 14-4=10. The difference of 24 and 14 is also 10. But the difference between 32 and 24 is 8. Since 8 isn't the same as the other differences, it's not an arithmetic sequence. That should be enough for you to determine which of the remaining sequences is arithmetic.
