The plane roughly goes 458 miles an hour, at this rate the plane will travel 3664 miles in 8 hours
Answer:
7.5
Step-by-step explanation:
Given;
- Bert earns $35,000 gross annual salary
- Any amounts earned up to $20,000 are taxed at x%
- Any amounts earned beyond $20,000 are taxed at 20%
- Bert pays $4,500 per annum in income tax
To find x
Amount earned beyond $20,000
= $35,000 - $20,000
= $15,000
That is the amount to be taxed at 20%
Therefore,
x% × 20000 + 20% × 15000 = 4500
200x + 3000 = 4500
200x = 4500 - 3000
200x = 1500
x = 1500/200
x = 7.5
Tan (x + pi/2) = -cot x
<span>tan (pi/6 + pi/2) = -cot (pi/6) </span>
<span>tan (2pi/3) = -cot (pi/6) </span>
<span>-sqrt (3) = -[sqrt 3] <<< so it is true for x = pi/6</span>
Option B correct answer
g(x) =1/3 F(x)
