5. in a physics lab, an artifact is dropped from the roof of the school building, 98 feet above the ground. the height ℎ (in feet) of the ball above the ground is given by the function ℎ 푡 = –16푡 ' +98, where 푡 is the time in

The function will  be,

 (in feet)

Step-by-step explanation:

We know that acceleration due to gravity in F.P.S system is given by,

 and if a body is dropped from a height of   feet to fall to the ground then after t seconds it's height above the ground will be given by,

feet [where the acceleration due to gravity is given by g]  provided it is greater than or equal to zero.

here,

and feet

So,

⇒ [in feet]

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".

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
