Answer: Both Technicians

Step-by-step explanation: A drive shaft which is also called the propeller shaft,is a major part of a the drive train/ unit of a vehicle with the role of Transmitting TORQUE POWER TO THE WHEELS,it is usually made up of STEEL.

Drive shaft is elongated,it is round and it requires needle bearing for friction reduction and taping to prevent it from falling off when the shafts are removed during servicing. Both Technicians are correct as both options are needed.

An office building has two elevators. One elevator starts out on the 4th floor, 35 feet above the ground, as it’s defending at a
iren2701 [21]

The system of equations are y = 35 - 2.2x and y = 1.7x

<em><u>Solution:</u></em>

Given that, office building has two elevators.

<em><u>One elevator starts out on the 4th floor, 35 feet above the ground, as it’s descending at a rate of 2.2 feet per second</u></em>

Let "x" be the number of seconds for which the elevator is descending

Therefore, for "x" seconds the descended feet is 2.2x feet

The elevator is at 4 th floor, 35 feet above ground

Therefore, from 35 feet, the elevator has descended 2.2x feet for "x" seconds

Let "y" be the final position of elevator after "x" seconds

Therefore,

y = 35 - 2.2x

<em><u>The other elevator starts out at ground level and is rising at a rate of 1.7 feet per second</u></em>

Here, the elevator is rising at a rate of 1.7 feet per second

Therefore, for "x" seconds, the elevator has raised 1.7x feet

Here the elevator is at ground level, therefore

y = 1.7x

Thus the system of equations are y = 35 - 2.2x and y = 1.7x

Geometry problem in the picture: Find the measure of the angle to the nearest degree
Anit [1.1K]

Answer:

? Is 41 degrees

Step-by-step explanation:

SOH CAH TOA

Hypotenuse is 60

Adjacent is 45

Hypotenuse and adjacent - Cos

(Cos inverse to find the angle)

Cos(?) = a/h

Cos(?) = 45/60

Cos-(45/60) =?

? = 41.40962211

Think carefully about the angle relationship the following represents.
lisov135 [29]

Answer:

See below ↓↓↓

Step-by-step explanation:

<u>Subquestion #1</u>

  • These angles form a linear pair
  • They are supplementary, and add up to 180°
  • 2x + 48 = 180
  • 2x = 132
  • <u>x = 66</u>

<u></u>

<u>Subquestion #2</u>

  • These angles are complementary, and add up to 90°
  • 35 + 4x + 7 = 90
  • 4x + 42 = 90
  • 4x = 48
  • <u>x = 12</u>

<u></u>

<u>Subquestion #3</u>

  • As in #1, they are a linear pair, and are supplementary
  • 3x + 54 = 180
  • 3x = 126
  • <u>x = 42</u>
