Answer:
The Maximum value is
Step-by-step explanation:
Given,
(equation-1)
Differentiate above equation with respect to 'x',
--- (equation 2)
Again differentiate above equation with respect to 'x',
------- (equation 3)
From equation-2 we see,
The value of , , .
Now, for maximum or minimum, the first derivative must be 0.
For maximum,
So,
Using the quadratic formula, we find the roots of
or
For ,
Which is minimum value at
And for ,
Which is maximum value at
Plug in equation-1,
So the Maximum value is
a) If the motorcycle starts from rest, then we have an initial speed equal to zero (V0 = 0), with this we can choose a formula that does not contain the initial speed, now we also know that what it asks us is the time that it takes a certain speed to pass, so the formula we will use will be:
Clearing "t"
The distance is in Kilometers, we first need to pass this distance in meters, so we'll need to do our conversion:
1.6 km = 1600m
Substituting our data into the formula:
So the motorcycle will take 84.32 seconds to travel 1600 meters.
b) Since we are asked to obtain the speed in the time it took for the 1600 meters, we are going to use the following formula.
Substituting our data:
In order to express the final result of the speed, in terms of km/h, we would only apply the conversion factors.
There are two months that begin with the letter M (March, May)
So the probability is 2/12 = 1/6 ≈ 0.17 rounded to the nearest hundredth.

Answer
its d
Step-by-step explanation:
Answer:
Used car have the highest range of 75
Step-by-step explanation:
Yeah the type of car that have the highest range In monthly sales.
we know that
The range is the difference between the highest and the lowest value
First we,
calculate the range in monthly sales for the new car
highest value=51
lowest value=20
range=51-20
range=31
Secondly,we
calculate the range in monthly sales for used car
highest value=87
lowest value=12
range=87-12
range=75
