first of all you need to find the missing length on the adult version. so the work would be: -add up all the known sides of adult so (56+56+35)=147
-then take the total perimeter and subtract so 167-147=20
-then you need to compare the two known sides of both the adult and kids version. so that would be the bottom line EM. They are 35 and 14 so divide 35/14=2.5
Now you know the dilation so you can figure out the missing side GA on the childs by taking the missing side from the adult dividing by the dilation 2.5 to get the answer so 20/2.5= 8
Notice that the height of the pine cone when it hits the ground is zero. So, to find the tame it takes for the pine cone to hit the ground, we just need to replace the height, , with 0 in the function, and solve for time :
Since time cannot be negative, the solution is seconds.
Since 1.5 second is significantly less than 2 seconds, we can conclude that <span>2 seconds is not a reasonable answer to this model.</span>
