A cannonball is fired at an initial velocity of 85.76m/s elevated at an angle of 45° 1. What is the initial velocity of the cannon ball?

2. How long will it take the cannonball travel before it lands on the ground?

3. What is the horizontal displacement of the projectile?

4. What is the maximum height reached by the cannonball?

5. What is the initial horizontal velocity?

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
