Step-by-step explanation:

Two lines are parallel if they have the same slope.

To find the slope of the line that passes through two points, (x_{1}, y_{1}) and (x_{2}, y_{2}), you can use the following formula:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

For the first set of points, (-1, -2) and (4, 4), we can find the slope with the following:

\frac{4 - (-2)}{4 - (1)}

\frac{4 + 2}{4 + 1}

\frac{6}{5}

For the second set of points, (6, 3) and (-1, -3), we can find the slope with the following:

\frac{-3 - 3}{-1 - 6}

\frac{-6}{-7}

\frac{6}{7}

Since the two slopes are \frac{6}{5} and \frac{6}{7}, the two lines are not parallel.

HURRY HELP PLS‼️‼️‼️
Brums [2.3K]

Answer:

Step-by-step explanation:

To solve this problem you need the function

 

h(t) = -16t2 + v0t + h0

where t = time

v0 is the initial velocity, which in our case is 0

h0 = initial height, which in our case is 256

h(t) = 0 since we want to know when the ball will hit the ground.

 

0 = -16 t2 + 256

 

And we can solve for t

 

If we rearrange the terms we see that this is a difference of 2 squares

0 = 256 - 16t2

 

0 = (16-4t)(16+4t)

Setting each factor = 0

16-4t=0       16+4t=4

t = 4             t = -4

 

The second solution is discarded as time cannot be negative.

 

So the ball will hit the ground in 4 seconds.
