Answer:
14 is 62.5 and 15 is 156
Step-by-step explanation:
Answer:
1. -3/5x^41+5/12
2. 14/3 or 80/21 (see explanation in step -by -step explanation)
Step-by-step explanation:
1. For this you just have to simplify it
2. for this one if it is just 2/3 - (-4) then it would be 14/3 but if it is 2/3 - (-4)-6/7 then you get 80/21 ( to solve this you also just simplify it)
Answer:
(A) 5.47 km
(B) 1.38 km
Step-by-step explanation:
The relationship between Pressure (mmHg) and Height (km) is given by the equation below:
p =760 e⁻ 0.145h----------------------------------------------------- (1)
(a) The height of the aircraft can be calculated by making 'h' the subject of equation (1)
In (p/760) = -0.145 h
h = -In (p/760) /0.145
h= In (760/p)/ 0.145------------------------------------------------- (2)
For the aircraft, p =344 mmHg; substituting into (2)
h = In (760/344)/0.145
= 0.7926/0.145
= 5.4662 km
≈ 5.47 km
(b) p= 622 mmHg at the mountain top. Substituting into equation (2) we have:
h = In (760/622)/0.145
= 0.2003 / 0.145
= 1.3813 km
≈ 1.38 km
