A function associates x and y values. The graph of the function is formed by all the points such that x and y are actually associated, i.e. y=f(x).
So, if you choose x=4, you can see that the correspondant point on the graph has a y coordinate that is somewhere between 3 and 4 - much closer to 4 actually.
So, an estimated value could be around 3.75
Answer:
Ryan takes 6n+36m -42 seconds to reach the nth flag for the mth time.
Step-by-step explanation:
It takes Ryan to run from 1st to 6th flag in 30 seconds, so it takes him
30 * 6/3 = 36 seconds to make one complete round.
or it takes 6 seconds to run from one flat to the next.
To reach the nth flag (n=1,2,3,4,5, or 6)
Ryan takes 6(n-1) seconds.
To reach it the mth times, he needs to add 36(m-1) seconds.
So time it takes Ryan to reach the nth flag for the mth time takes
6(n-1) + 36(m-1)
= 6n - 6 + 36m - 36
= 6n+36m -42 seconds
Answer:
S(t)=
Step-by-step explanation:
We are given that
Th braking distance for a certain car moving at velocity v(in m/s) is given by
The velocity of car B(t) t seconds after starting =
We have to find the value for braking distance S(t) after t seconds.
To find the formula for braking distance we will substitute the value of velocity B(t) in place of v in D(v)
Substitute the value of velocity then we get
Then, we get
The formula for the braking distance S(t) after t seconds=
The formula for the braking distance S(t) after t seconds=
