The ball's velocity will be represented by the derivative of its distance function:
Now find the times
for which this is equal to 30, i.e. solve
This has two solutions,
, but only one is positive and falls in the interval
. So the velocity reaches 30 cm/s when
.
Answer:
Step-by-step explanation:
Add on both sides and subtract on both sides to leave x's on the left side and independent values on the right.
Solve the fractions.
Convert the mixed fraction to an improper fraction. You can do this by multiplying 1 times 35 and adding 2.
Now use the reciprocal (inverse fraction) and multiply on both sides to isolate x.
You would do 29.85 ÷ 3 which equals 9.95. You would do the in verse operation. Hope I helped you.
By the rule of 3 simple:
53/100 = x/113100
x = 53*113100/100 = 59943
Answer:
15
Step-by-step explanation:
the pattern is like this
start with 1 then add 2 equals 3
start with 3 then add 3 equals 6
so 6 add 4 equals to 10
and the 5th term will be 10 add 5
equals to 15
