To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows:

0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s

Answer:
Part A: 1
Explain: The solution for a pair of lines is where they intersect.
Part B: (3,4)
Explain: (3,4) is the place where the lines intersect.
Answer:
No the triangle are not same because the outer length of triangle is not same
#1 - 2/3
#2 - 1 1/3
#3 - 2/3
#4 - 1 1/2
<span>y=2\3x-17and 4x-6y=-7 implies - 6y= - 4x -7, and then y= (-4/-6)x +7/6 and so
y=2/3x+7/6
but when we have y=ax+b and y=a'x+b', the two lines are parallels if a=a', in our case 2/3=2/3 the lines are parallel
