Answer:
The difference between the times is just 6.09
Step-by-step explanation:
Here, we are interested in finding the difference between the times when two athletes finished their races.
While one finished at 24.53, the other finished at 18.44; So the difference between the two will be calculated by subtracting the time which was less from the time which was more;
Mathematically, that would be 24.53 - 18.44 = 6.09
Answer:
h(x) = 1/4x
Step-by-step explanation:
To find the inverse, first we rewrite the function using y instead of f(x):
y = 4x
Next we switch x and y:
x = 4y
Solve for y by dividing both sides by 4:
x/4 = 4y/4
x/4 = y
1/4x = y
