Answer:
0.3125
Step-by-step explanation:
If it decreases by 50% each time it hits the ground then all you have to do is divide 10 by 2 (50%) each time it bounces.
10 / 2 = 5 (first bounce)
5 / 2 = 2.5 (second bounce)
2.5 / 2 = 1.25 (third bounce)
Ect. . .
Until on the fifth bounce it is 0.3125m high.
Basically your negatives beside each other turn into a positive because two negatives equals a positive
Answer:
option 2
Step-by-step explanation:
The problem can be solved using Pythagoras' identity for a right triangle.
The angle between due East and due North is 90°
The solution here involves using the Cosine rule.
let x be the direct distance between house and office, then
x² = 17² + 21² - 2(17)(21)cos90° → option 2
Note that since cos90° = 0 the equation reduces to
x² = 17² + 21² ← Pythagoras' identity
