Answer:
The plane have traveled 1512.9 m from the time took off
Step-by-step explanation:
Acceleration 
Initial speed = u = 0
Final speed = v = 246 m/s
Time = t = 93
We are supposed to find how far would the plane have traveled from the time took off
We will use equation of motion

Hence The plane have traveled 1512.9 m from the time took off
Answer:50mm
Step-by-step explanation:
An equilateral triangle has 3 equal sides. So the 150mm is divided by 3 to get the length of each side
Answer:
45/51
Step-by-step explanation:
SOH CAH TOA
Sin x = Opposite/hyp
Cos x = Adjacent/hyp
Tan x = Opposite/Adjac
Here we're looking for Sin R, so we want to find opposite side over the hypotenuse.
Thus, 
Answer:
The equation of demand function is

Step-by-step explanation:
We have two point demand function
(38000,10) and (42000,8)
Here
=38,000,
=10,
=42000,
=8
The slope of the demand function line is




The equation of demand function is





The original area of the triangle is (18 * 5) / 2 = 45
18 cm decreases by 30% = 18 - 0.30(18) = 12.6
5 cm increased by 20% = 5 + 0.20(5) = 6
so the new area is (12.6 * 6)/ 2 = 37.8
so there is a percent decrease
percent decrease = (original number - new number) / original number....x 100
(45 - 37.8) / 45 = 7.2 / 45 = 0.16.....x 100 = 16%..so there is a 16% decrease
