a ball is thrown downward from the top of a 120-foot building with an initial velocity of 16 feet per second. the height of the ball h in feet after t seconds is given by the equation h= -16t squared - 16t + 120. how long after the ball is thrown will it strike the ground? the time is takes for the ball to strike the ground is about __ seconds

step-by-step explanation:

4+4+2x

or

2x+8

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
