WE see that at time t=0 the ball's height is 6 feet so we know the origin of our coordinates is the ground (h=0 feet) So we need to solve this quadratic equation for the value of t that makes the equation 0. There will be 2 solutions, one will be right and the other is usually impossible (all quadratics have two roots)
Using the quadratic formula (google it if you're unfamiliar, Brainly's math editor doesn't show things like that too nicely) I get t = 1.5s. (the other root is -0.25)
Hints: 0.234 divided by 0.78 equals a decimal
The decimal starts with 0.
The ending number is in the tenths
Answer:no solution the lines are parallel they have the same slope
Step-by-step explanation:
8x+2y=14
-8x. -8x
2y= -8x+14
Divide all by 2
Y= -4x +7
8x+2y=4
-8x. -8x
2y= -8x+4
Divide by 2
Y-= -4x+2
Since they both have -4x they have the same slope they never touch making them parallel
One reason is so the teacher can actually see that your working the problem out
