Well the position function is:

h(t)=-16t^2+256

It will hit the ground when h(t)=0

-16t^2+256=0  factor out -16

-16(t^2-16)=0  factor difference of squares...

-16(t+4)(t-4)=0, since t>0

t=4 seconds

Volume of rectangular prism is first edge*second edge*third edge (product of
prism dimensions) 
1st edge has 4 small cubes , edge of the small cube=1/4,
so 1st edge of the large cube =1/4*4=4/4 (it could be written as 1)
2d edge has 3 small cubes , so  2d edge= 3*1/4=3/4
3d edge has also 3 small cubes , so 3d edge= 3*1/4=3/4
Volume= first edge*second edge*third edge=4/4*3/4*3/4=1*3/4*3/4=9/16
Answer 4/4*3/4*3/4=9/16

Answer:

y - 3 = - 4 ( x + 4)

Step-by-step explanation:

(-4,-3) and (4,1)

Slope = (1 + 3)/(4 + 4) = 2/8 = 1/4

Perpendicular lines, slope is opposite and reciprocal so slope of the line that is perpendicular to the given line is -4

Equation in point slope form, passing thru (-4 , 3)

y - 3 = - 4 ( x + 4)
