Tossing a Ball Clayton Kershaw throws a baseball up in the air on
Earth and Pluto. The graphs of both throws are shown
to the left:
Earth = Blue
Pluto = Purple
The baseball is thrown up with an initial velocity of 20
feet/second and 5 feet above the ground.
1. How many seconds pass before the ball hit the
ground on Pluto?
ta
20
30
time (seconds)
2a. What is the maximum height of the baseball on
Pluto?

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".

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
