Answer:
∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then translate point C to point B to confirm∠IBE ≅ HCE.

Step-by-step explanation:
Answer: -2.1, -0.5, 5/100, 0.5, √5
Step-by-step explanation:
Start with the negative numbers. Take the absolute value - the ones with the largest absolute value are the farthest from 0, so they are the smallest numbers.
-2.1, -0.5
Then, convert the numbers not in decimals to decimals.
5/100 = 0.05
√5 is about 2.3.
5/100, 0.5, √5
1. The time taken for the water to fall that much is 0.2 s
2. The initial speed of the water is 4 m/s
<h3>1. How to determine the time </h3>
- Height (h) = 20 cm = 20 / 100 = 0.2 m
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) =?
h = ½gt²
0.2 = ½ × 9.8 × t²
0.2 = 4.9 × t²
Divide both side by 4.9
t² = 0.2 / 4.9
Take the square root of both side
t = √(0.2 / 4.9)
t = 0.2 s
<h3>2. How to determine the initial speed</h3>
- Horizontal distance (s) = 80 cm = 80 / 100 = 0.8 m
- Time (t) = 0.2 s
- Initial speed (u) =?
s = ut
Divide both sides by t
u = s / t
u = 0.8 / 0.2
u = 4 m/s
