a ball a is thrown vertically upwards at 25 ms from a point p. three seconds later a
second ball b is also thrown vertically upwards from the point p at 25 ms. taking the
acceleration due to gravity to be 10 ms? , calculate

a. the time for which ball a has been in motion when the balls meet
b. the height above p at which a and b meet.

i dont know i just need points

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
