25 points Which of the following coordinate systems is most common?
a. spherical
b. polar
c. cylindrical
d. rectangular
Answers
Answer:
D. Rectangular
Explanation:
This is because rectangular coordinate systems are used in plotting common straight lines graphs with the formulae,
Y = Mx + c
Where y is the vertical coordinate
X is the horizontal coordinate
M is the dlope of the line
C is the y-axis intercept
Answer:
d. rectangular
Explanation:
Because it is the simple one and is used the most in calculations.
For example, if we want to make an equation of straight line, it would be like
here
y=vertical axis
x=horizontal axis
m= slope of straight line
c=point on y axis where line is cutting y axis
Hence, rectangular coordinate system is the simplest one and is used most commonly.

Peggy Annette Whitson was born February 9, 1960, Mount Ayr, Iowa, U.S.
She was the first female commander of the International Space Station.
She holds the record among American astronauts and among women for spending the most time in space, nearly 666 days.
She received a B.S. in biology and chemistry from Iowa Wesleyan College in Mount Pleasant, Iowa, in 1981 and a doctorate in biochemistry from Rice University in Houston in 1985.
She flew into space for the first time on June 5, 2002, as a flight engineer on Expedition 5 to the ISS, aboard the space shuttle Endeavour on mission STS-111.
She, from 2009 to 2012, Whitson was chief of the Astronaut Office, which oversees all NASA astronaut activities, including crew selection and training.
She was the first woman and the first civilian to hold that position.
She was sent into space 3 times.
Her total of 10 career spacewalks and their combined duration of 60 hours 21 minutes were records for a female astronaut.
She retired from NASA in 2018.

Minor scoring is not necessary a reason to machine a brake drum. Option B is correct.
What is a Drum Break?
A drum brake is a type of brake that relies on friction created by a set of shoes or pads pressing outward against a revolving cylinder-shaped element known as a brake drum.
Drum brakes are commonly used to describe brakes in which shoes press on the inner surface of the drum. Drum brakes provide consistent braking force regardless of whether the vehicle is moving forward or backward.
This is due to the fact that drum brakes produce the same braking force in both directions. This kind is typically seen on passenger car rear brakes. Drum brakes were so named because the components were placed in a circular drum that revolved with the wheel.
Inside was a pair of shoes that would be forced against the floor if the brake pedal was pushed.
Therefore, option B is correct.

Carbon dioxide is a harmful substance may be stored there, If a building is too humid.
What is humid?
Humidity is a measurement of the amount of water vapour in the atmosphere. If there is a lot of water vapour in the air, the humidity will be high. As the humidity increases, it feels more humid outside. In weather reports, humidity is frequently described using the word "relative humidity."
It normally has a temperature of at least 90 °F and a relative humidity of at least 30% when the air is hot and humid.
Because excessive humidity slows down perspiration evaporation, humid heat is riskier than dry heat. Patients may endure organ failure, a rapid heartbeat, high blood pressure, and even death if they are not given the chance to cool off.
Thus, it is Carbon dioxide.
