If a pistol bullet is fired vertically at an initial speed of 100 m/s, the height in metres after t seconds is given by h = 100t – 10t2
Find the maximum height attained by the bullet
When does the bullet return to the ground?

160

step-by-step explanation:

idk

i hope i

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

answer: you will have more water.
