I found that it was -1, but everything online is telling me -36.
Answer:
Hey the answer is one.
Step-by-step explanation:
There is a quizlet with 18 of the answers with explanations on it just type in the unit subject and this question and it should pop up.
But on a side note,
I don't know who deleted my answer last time but I was giving you a resource to use if you want to learn the full step by step explanation look on your lesson videos or ask your teacher. This site i have found lets people give one another answers so unless this person and some army is planning on stopping everyone from giving answers i think they should just stop using this site.
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
Answer:
A and C
Step-by-step explanation:
The absolute value of a negative number is positive; I don't know why A and C are identical though
<em><u>Answer:</u></em>
<em><u>y = 5, 3; x = 171, 155</u></em>
<em><u>Step-by-step explanation:</u></em>
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155
