C. 11
Step-by-step explanation:
We know that Hector is writing the expression in the expanded form.
Now, = 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7
i.e. 7 is multiplied 11 times in order to obtain the result .
Thus, we see that there are 11 terms being multiplied in the expanded form.
Hence, option C is correct.

Answer:

  a. A

  b. B

  c. D

  d. E

  e. C

Step-by-step explanation:

Linear pairs are supplementary, so ...

  ∠2 = 180° -∠1 = 180° -130° = 50° . . . (a)

  ∠6 = 180° -∠7 = 180° -70° = 110° . . . (d)

Vertical angles are congruent, so ...

  ∠5 = ∠7 = 70° . . . (c)

Exterior angles are equal to the sum of the opposite interior angles, so ...

  ∠4 = ∠2 +∠5 = 50° +70° = 120° . . . (e)

__

  ∠1 = ∠3 +∠5

  130° = ∠3 +70°

  ∠3 = 130° -70° = 60° . . . (b)

HII PLEASE HELP ME IN THIS
Rzqust [24]

Step-by-step explanation:

(i) Sum the forces at point M in the x direction.

∑F = ma

-T sin 30° − T sin 30° + 5 N = 0

2T sin 30° = 5 N

T = 5 N

(ii) Sum the forces on the ring in the x direction.

∑F = ma

T sin 30° − N = 0

N = 2.5 N

Sum the forces on the ring in the y direction.

∑F = ma

T cos 30° − mg − Nμ = 0

Nμ = T cos 30° − mg

2.5 μ = 5 cos 30° − 2

μ = 0.932

(iii) Sum the forces on the ring in the y direction.

∑F = ma

T cos 30° − m₁g − m₂g + Nμ = 0

m₂g = T cos 30° − m₁g + Nμ

m (10) = 5 cos 30° − 2 + (2.5)(0.932)

m = 0.466 kg

How do i do this? I dont really know where to start
Alex787 [66]
Well, I don’t necessarily remember how to sketch a plane. However, I can help get you started by defining some words they use and hopefully you will be able to do this on your own!

So this plane is made up of three points, names E, D and B. (Edit: This plane may be made up of four points, because of point A.)

E and B are collinear with A. This basically means that they all are on the same line.

D is a vertex. This basically means that it is a dot that these two lines called rays will shoot out of it. I will attach a picture of a vertex.

CD and FD are called rays. See those little lines above them? I’ll be sure to attached another image so that you know what I’m taking about. Anyway, that means they are rays. Rays are like never ending lines; they start at a point and the line will go on for infinity.

(Edit: where did the point f come from? I really wish you would have attached the full picture...)

Whelp, that’s all I’ve got! Good luck!!

(Edit: looks like I can only attach one picture...I’ll comment the other.)
