See Explanation

Explanation:

Solving (4): 0.84554 as a fraction

The above number is to 5 decimal places, so the fraction equivalent is:

Divide numerator and denominator by 2

Solving (5):

The midpoint, M is calculated as follows:

Where

The distance, D is calculated using:

Solving (1): The expression for f(x) is not clear. So, I'll make use of:

Substitute each value of the domain in

The range is:

Solving (2):

Shape: Open Cylinder

The surface area is calculated as:

Solving (3):  

The value of a is not clear. So, I'll assume that a is a

Given that

Find

Substitute 3a for b

Absolute value of 4a is 4a. So,

Solving (9):

Given

--- Principal

--- Rate

--- Time in years

The amount (A) is calculated as follows:

Hence, the amount at the end of 2 years is:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
