Answer:
1 1/6
Step-by-step explanation:
Given multiplication:
(3√6 - √2)(4√2 - √6)
= 3√6(4√2-√6)-√2(4√2-√6)
= 3√6*4√2 - 3√6*√6 - √2*4√2 + √2*√6
= 12√12 -3√(6*6) -4√(2*2) + √(2*6)
= 12√(4*3) - 3√(36) - 4√(4) + √(12)
= 12*2√3 - 3*6 - 4*2 + 2√3
= 24√3 - 18-8 +2√3
= 24√3 + 2√3 - 18-8
= 26√3 - 18-8
= 26√3 - 26
= 26(√3-1).

<h2>
It takes 3.31 minutes the airplane to climb to a height of 14,000 feet</h2>
Step-by-step explanation:
Angle with horizontal = 15°
Velocity of plane = 272 feet per second angle of ascent is 15 degrees
Velocity of plane = 272 cos 15 i + 272 sin 15 j = 262.73 i + 70.40 j ft/s
Vertical velocity = 70.40 ft/s
Vertical displacement = 14000 ft
We have
Vertical displacement = Vertical velocity x Time
14000 = 70.40 x Time
Time = 198.87 seconds = 3.31 minutes
It takes 3.31 minutes the airplane to climb to a height of 14,000 feet
