1) A soccer ball is kicked across a field at an angle of 44° with an initial speed of 21 m/s. i) Write a set of parametric equations for the motion of the soccer ball.
ii) Determine how long the soccer ball was in the air.
iii) Determine how far the soccer ball traveled in the air.
iv) Determine when the soccer ball reached its maximum height.
y Determine the maximum height reached by the soccer ball.

i think it is x = 1.2

do you have the measurements?

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
