Answer:
f^-1(x) = 1/5 x
Step-by-step explanation:
y = 5x
Exchange x and y to find the inverse
x = 5y
Solve for y
1/5x = y
The inverse is 1/5x
Answer:
1.5 min
100 rotations
Step-by-step explanation:
to find 300 rotations time duration use the half-minute,
to find half of a minute divide the amount in one minute (200) by 2
200/2 = 100
then mutiply the 100 times 3 to find the time
100 * 3 = 300
therefore 30 sec (100 rot.) and 3 (3 times)
30 * 3 = 90
90 seconds minus 60 (one minute) is 30
so then it is equal to 1.5 minutes aka 1 min. 30 sec.
How long does it take to complete 300 rotations? 1.5 minutes (1 min. 30 sec.)
How many times does it rotate in a half minute? 100 rotations
hope this helps:)

Answer:
The expression which gives the probability that she will select two red cubes = 5/12 * 4/11 ....
Step-by-step explanation:
According to the statement there are 4 red cubes and 7 white cubes.
The total number of cubes are = 7+5 = 12
If she picks up one red cube then the number of ways of picking up red cubes out of 12 is = 5/12
If she picks up 2nd red cube then the number of ways of picking up 2nd red cube = 4/11
Therefore the expression which gives the probability that she will select two red cubes = 5/12 * 4/11 ....
