uranmaximum [27]3 years ago
6 0

Answer:

a_{n} = 4n - 11

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

d = - 3 - (- 7) = 1 - (- 3) = 5 - 1 = 4

and a₁ = - 7, hence

a_{n} = - 7 + 4(n - 1) = - 7 + 4n - 4 = 4n - 11

Find m∠MON<br> I have a hard time with theses
fredd [130]

Answer:

m∠MON = 15°

Step-by-step explanation:

The given parameters are;

m∠LON = 77°

m∠LOM = 9·x + 44°

m∠MON = 6·x + 3°

By angle addition postulate, we have;

m∠LON = m∠LOM + m∠MON

Therefore, by substituting the known values, we have;

∴ 77° = 9·x + 44° + 6·x + 3°

77° = 9·x + 44° + 6·x + 3° = 15·x + 47°

77° = 15·x + 47°

77° - 47° = 15·x

15·x = 77° - 47° = 30°

15·x = 30°

x = 30°/15 = 2°

x = 2°

Given that m∠MON = 6·x + 3° and x = 2°, we have;

m∠MON = 6 × 2° + 3° = 12° + 3° = 15°

m∠MON = 15°.

a. "Collinear" means "on the same line". The diagram shows point K on the same line with M and P, so ...

  yes, M, P, and K are collinear

__

b. N, W, and U are the corners of face NUWQ, so point Q is also in that plane.

__

c. The plane MPQ includes face MPQN. The plane TVP includes face TVPM.

Line MP (or PM) is the line where these planes intersect.
