Find the slope of the line that passes through (-3,-2) and (-3,2)

fiasKO [112]

Answer:

undefined

Step-by-step explanation:

The x value does not change, which means it is a vertical line

Vertical lines have an undefined slope

we can check using

m = (y2-y1)/(x2-x1)

=(2- -2)/( -3 - -3)

= (2+2)/( -3+3)

when a cannonball is fired, the equation of its pathway can be modeled by h=-16t squared + 128t. find the time it will take for

Rashid [163]

At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.

Thus, the time it will take the cannonball to reach the ground is given by

$-16t^2+128t=0 \\ \\ \Rightarrow t(-16t+128)=0 \\ \\ \Rightarrow t=0\ or\ -16t+128=0 \\ \\ \Rightarrow16t=128 \\ \\ \Rightarrow t= \frac{128}{16} =8$

Therefore, it will take the cannonball 8 seconds to reach the ground.
