When the ball has traveled a distance of

(2.5,10.5)

Step-by-step explanation:

Given that a ball is thrown verically upwards with an initial velocity. We know that the path is a trajectory as a parabola.

From graph we find that horizontal is in yards and vertical is in feet.

WE have to find the coordinates of A

When ball is thrown upward, acceleration due to gravity is -32 ft/s^2

Since height = s=+h0

we get h0 as initial height.

But without any calculation from the graph we find out these coordinates as

x coordinate = 2.5(since in the middle of 0 and 5)

y coordinate = 10.5(since in the middle of 9 and 12)

(2.5,10.5) is the coordinate of A

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
