maintaining the Earth's temperature structure
d.
all of the above
Please select the best answer from the choices provided
A
B
C
D
Answer:
the answer is D.all of the above
Step-by-step explanation:
The ozone layer helps to sustain terrestrial life by absorbing incoming UV radiation.
Option A is the correct answer.
What is an ozone layer?The ozone layer is a layer of gas in the Earth's stratosphere that helps to protect the planet from the harmful effects of ultraviolet (UV) radiation from the sun.
We have,
UV radiation can cause damage to living organisms, such as skin cancer, cataracts, and other health problems.
The ozone layer absorbs much of this radiation, preventing it from reaching the Earth's surface and thus helping to sustain terrestrial life.
Option B is incorrect because the ozone layer is located in the stratosphere, above the troposphere.
Option C is incorrect because while the ozone layer can play a role in maintaining the Earth's temperature, its primary function is to absorb UV radiation.
Option D is incorrect.
Thus,
The ozone layer helps to sustain terrestrial life by absorbing incoming UV radiation.

A measurement is taken to be 13.6 in. and the absolute error is 0.05 in. What
is the percent of error? Round off your answer to 3 decimal places. *
Given parameters:
True value of measurement = 13.6in
Absolute error = 0.05in
Unknown:
Percent of error = ?
Solution:
Error is an inconsistency introduced into a particular data set or reading.
% error = [tex]\frac{absolute error}{true value}[/tex] x 100
% error = [tex]\frac{0.05}{13.6}[/tex] x 100 = 0.368%

Step-by-step explanation:
A taxicab service charges customers by the mile. The graph
shows the number of miles a taxicab drives and the amount of
money the customer pays.
Which statement best describes the rate of change for the
situation?
The amount a customer pays increases $0.50 per
mile driven
The amount a customer pays increases $0.60 per
mile driven
The amount a customer pays increases $12 per mile
driven.
The amount a customer pays increases $21 per mile
driven
Answer:
The second option: The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
As seen on the graph, we are given the points (20,12) and (35,21).
This means that at 20mi driven, the amount paid is $12, and at 35mi driven, the amount is $21.
To find the rate of change we divide the distance driven by the cost to find the cost per mile:
20/12 = 0.6
35/21 = 0.6
The slope is 0.6, so it costs an extra $0.6 for every mi driven. Therefore it is the second option: The amount a customer pays increases $0.60 per mile driven.
Hope this helped!
Answer:
The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
$0.6/mi is the rate of change, y = mx + b, so m.is also called rate of change & b is the initial value of x, in the graph b = 0. making m the subject of the equation, then m(roc) = 0.6.

Hey there!
Let's solve your equation step-by-step.
[tex]\fbox{5y−6=2y(9)−32}[/tex]
Step 1: Simplify both sides of the equation.
[tex]\fbox{5y−6=2y(9)−32}[/tex]
[tex]\fbox{5y+−6=18y+−32}[/tex]
[tex]\fbox{5y−6=18y−32}[/tex]
Step 2: Subtract 18y from both sides.
[tex]\fbox{5y−6−18y=18y−32−18y}[/tex]
[tex]\fbox{−13y−6=−32}[/tex]
Step 3: Add 6 to both sides.
[tex]\fbox{−13y−6+6=−32+6}[/tex]
[tex]\fbox{−13y=−26}[/tex]
Step 4: Divide both sides by -13.
[tex]\fbox{−13y/−13 = −26/−13}[/tex]
[tex]\fbox{y=2}[/tex]

Solve the equation
3/2 - 6x) + 1 = 3 – 5x.
Answer:
x = - 1/2
Step-by-step explanation:
(3/2 - 6x) + 1 = 3 - 5x
-6x + 5/2 = 3 - 5x
5/2 = 3 - 5x + 6x
5/2 = 3 + x
5/2 - 3 = x
-1/2 = x
x = -1/2
Please mark me the brainliest!?!
[tex] \frac{3}{2} - 6x +1 = 3 - 5x \\ [/tex]
Plus sides 6x
[tex] \frac{3}{2} - 6x + 6x + 1 = 3 - 5x + 6x \\ [/tex]
[tex] \frac{3}{2} + 1 = 3 + x \\ [/tex]
Subtract sides -3
[tex] \frac{3}{2} + 1 - 3 = 3 - 3 + x \\ [/tex]
[tex] \frac{3}{2} - 2 = x \\ [/tex]
[tex] \frac{3}{2} - \frac{4}{2} = x \\ [/tex]
[tex]x = - \frac{1}{2} \\ [/tex]
