Which statement best defines the two quantities that are measured to find the rate at which an airplane descends? A) The quantit
Schach [20]

The <em>correct answer</em> is:


C) The quantity of distance measured in feet depends on the quantity of time measured in minutes.


Explanation:


The rate of an airplane's descent would be found using the distance it descends and the amount of time that takes.


In this situation, the amount of time that passes causes the distance the plane descends to change; this means that the distance depends on the time.

Please help! I need the surface area for both. Absurd answer are not tolerated. Thanks if you help!
Natasha_Volkova [10]

Answer:

<h3>Figure 1</h3>
  • Perimeter of base = 5 + 5 + 8 = 18 ft
  • Height = 7 ft
  • Base area = 1/2(8)(3) = 12 ft²

<u>Surface area:</u>

  • S = 18*7 + 2*12 = 150 ft²
<h3>Figure 2</h3>

<u>Surface area of cube:</u>

  • S = 6a² = 6(2.5)² = 37.5 m²

<u>Surface area of prism:</u>

  • S = 2(11 + 9)(7) = 280 m²

<u>Overlapping area:</u>

  • S = 2.5² = 6.25 m²

<u>Surface area of composite figure:</u>

  • S = 280 + 37.5 - 2(6.25) = 305 m²

How do I graph this. I need to find the solution
Sergio039 [100]
To graph y=-7x-3, you're going to make your first coordinate at (-3,0) b/c that is your y-intercept and you will continuously move down 7 and right one.

To graph y=4, you will simply make a horizontal line through the to coordinate (4,0).

Hope that helped.

Find Arc PR<br>Please help and give explanation ​
garri49 [273]
Arc PR is 156 degrees. Since both angles are are making the forming arc they should be congruent. You can put (5x+23)=(9x-21) which is x=11.
Then you plug in 11 into your equation; 5(11)+23=78.
Since the vertex is on the outside of the circle then the arc is forms is 2 times the value of the angle.
78(2)=156

The angle between a 180-pound force F and AB= 5i + 2j is 30.Find the work done by F in moving and object from A to B.
Alexeev081 [22]

Answer:

W=839.464\ ft*lbf

Step-by-step explanation:

The work done is the product of the magnitude of the force applied to the object by the magnitude of the displacement of the object by the cosine of the angle between the force and direction of the displacement. This is:

W=|F|*|r|cos(\theta)

In this case

\theta=30\°

|F|=180 pound force

The magnitude of vector AB is:

|r|= \sqrt{5^2 + 2^2}\\\\|r|= \sqrt{29}\ fr

Finally the work is:

W=180*\sqrt{29}*cos(30\°)

W=839.464\ ft*lbf
