The speed of the airplane is 
Step-by-step explanation:
we know that

so

To convert m/sec to km/h the factor is 3.6
That means ----> Multiply the speed in m/sec by 3.6 to obtain the speed in km/h

Answer:
£100.32
Step-by-step explanation:
→ In order to work out the multiplier from a increase, you have to add 100 to the percentage and then divide by 100 so,
14 + 100 = 114
114 ÷ 100 = 1.14
→ This means the decimal multiplier is 1.14, now all we do is multiply the multiplier by the cost
£88 × 1.14 = £100.32
Answer:
0
Step-by-step explanation:
f(x) = √(x) + 12
g(x) = 2√(x)
(f-g)(x) = √(x) + 12 - 2√(x)
(f-g)(x) = 12 - √(x)
if x = 144
(f-g)(144) = 12 - √(144) = 12 - 12 = 0
