Answer:
Vertical angles are angles that are opposite each other when two lines intersect each other. And they are always equal.
==> 2y +5 = 4y
==> 4y - 2y = 5
==> 2y = 5
==>

Good luck on your assignment:)
Answer:
t=0.64
Step-by-step explanation:
h = -16t^2 +4t +4
We want h =0 since it is hitting the ground
0 = -16t^2 +4t +4
Using the quadratic formula
a = -16 b = 4 c=4
-b ± sqrt( b^2 -4ac)
----------------------------
2a
-4 ± sqrt( 4^2 -4(-16)4)
----------------------------
2(-16)
-4 ± sqrt( 16+ 256)
----------------------------
-32
-4 ± sqrt( 272)
----------------------------
-32
-4 ± sqrt( 16*17)
----------------------------
-32
-4 ± sqrt( 16) sqrt(17)
----------------------------
-32
-4 ± 4 sqrt(17)
----------------------------
-32
Divide by -4
1 ± sqrt(17)
----------------------------

To the nearest hundredth
t=-0.39
t=0.64
Since time cannot be negative
t=0.64
614.40 because 204.80 divided by 4 is 51.20 and 51.20 multiplied by 12 is 614.40
18/97 to the nearest hundreth is 0.18
