Air pressure may be represented as a function of height above the surface of
the Earth as shown below.
000121
P(h)= Pe
In this function, Po is air pressure at sea level, and his measured in meters.
Which of the following equations will find the height at which air pressure is
85% of the air pressure at sea level?
Answers
Answer:
a
Step-by-step explanation:
just took it
The following equation 0.85 P₀ = P₀ [tex]\rm e^{-0.00012h}[/tex] will find the height at which air pressure is 85% of the air pressure at sea level
What is Air Pressure ?The pressure exerted by air is called atmospheric pressure.
It is given that
P(h)=P₀ [tex]\rm e^{-0.00012h}[/tex]
Air pressure: P(h)
Height above the surface of the Earth (in meters): h
Air pressure at the sea level: P₀
Height at which air pressure is 85% of the air pressure at sea level:
h=?
P(h)=85% P₀
P(h)=(85/100) P₀
P(h)=0.85 P₀
Replacing P(h) by 0.85 P₀ in the formula above:
P(h)=P₀ [tex]\rm e^{-0.00012h}[/tex]
0.85 P₀ = P₀ [tex]\rm e^{-0.00012h}[/tex]
Therefore Option A is the correct answer.

Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we can find the missing angle by subtracting the measures of the given angles from 180
Thus missing angle = 180 - 34 - 71
180 - 34 - 71 = 75
Which means that the missing angle = 75
Answer:
? = 180 - (angle 1 + angle 2)
? = 180 - (71 + 34)
? = 180 - 105
? = 75°
=> To check is the answer is right, add all 3 angles together and their sum should be 180°

Answers
Answer:
Step-by-step explanation:
From late 2010, Kim Jong-un was viewed as successor to the leadership of North Korea. Following the elder Kim's death in December 2011, state television announced him as the "Great Successor". Kim holds the titles of General Secretary of the Workers' Party of Korea,[7] Chairman of the Central Military Commission, and President of the State Affairs Commission. He is also a member of the Presidium of the Politburo of the Workers' Party of Korea, the highest decision-making body. In July 2012, Kim was promoted to the highest rank of Marshal in the Korean People's Army, consolidating his position as Supreme Commander of the Armed Forces. North Korean state media often refers to him as "the Marshal" or "Dear Respected Leader". He has promoted the policy of byungjin, similar to Kim Il-Sung's policy from the 1960s, referring to the simultaneous development of both the economy and the country's nuclear weapons program.

Two cards are drawn from a deck of 52 cards. What is the probability that the first card
drawn is a king and the second card drawn is a heart, given that the first card is
replaced? (Hint: A deck has 4 kings and 13 hearts)
Answers
Answer:
1) P(First card was a king) = 1/13 2.) 1/4
Step-by-step explanation:
1) P(First card was a king) = n(King)/n(Total) = 4/52 = 1/13
2. P(Heart)13/52 = 1/4
Answer:
1/52
Step by step explanation:
First, find the probability that the first card will be a King. Since there are 4 possible kings, and 52 cards, the probability is 4/52.
Then, find the probability that the second card will be a heart. "given that the first card is replaced" means that there are 13 possible hearts regardless of the suit of the first card. So 13/52 is the probability.
To find the probability of both occurrences, multiply them.
4/52 * 13/52 = 52/2704
52/2704 can be simplified to 1/52. So that is the probability that the first card will be a king and the second card will be a heart.

Answer:
9 for the hypotenuse, [tex]\sqrt{64}[/tex] and [tex]\sqrt{25}[/tex] for the two legs
Step-by-step explanation:
For these types of problems, we need to make sure that the values of legs are as big as possible while keeping the hypotenuse larger than legs because otherwise, it won’t be a right triangle.
So for the hypotenuse, we have to put the largest number in this number bank because the hypotenuse has to be larger than both legs. So the hypotenuse will equal 9. The rest is simple. Get the numbers as large as possible. Since the hypotenuse must be larger than both legs, we cannot use sqrt(81) and sqrt(64) (that would’ve been sweet). So we have to use sqrt(64) and sqrt(25) because sqrt(49) and sqrt(36) are already taken since we can only use a number once.
I'm not an expert at this and I cannot guarentee that this is correct. But I hope that this helps.

If P(A) = 0.43 and P(
BA) = 0.89, find P(A and B).
Answers
Step-by-step explanation:
Me I don't know the answer teacher am waiting for the correction
The required probability of both A and B occurring is 0.3827.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The conditional probability of A provided B has happened, so it can be written as follows:
P(B|A) = P(A and B)/P(A)
Given that P(A) = 0.43 and P(B|A) = 0.89
We can use the formula of conditional probability:
P(A and B) = P(B|A) × P(A)
Substitute the given values in the above formula,
P(A and B) = 0.89 × 0.43
P(A and B) = 0.3827
Therefore, the probability of both A and B occurring is 0.3827.

Answer:
1) 12 (option b)
2) 41, 9, 40 (option a)
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
1) Let the unknown leg be x cm long. Thus,
5² + x² = 13²
Simplify and solve.
25 + x² = 169
x² = 144
x = 12
2) Apply the Pythagorean Theorem.
9² + 40² = 41² = 81 + 1600 = 1681
1681 = 1681
a is true.
Just in case, let's check the other options.
5² + 8² = 9² = 25 + 64 = 81
89 = 81, false
b is false
10² + 11² = 12² = 100 + 121 = 144
221 = 144, false
c is false
3² + 4² = 6² = 9 + 16 = 36
25 = 36, false
d is false
Thus, a is the answer.
