Vera_Pavlovna [14]3 years ago
3 0

Answer:

The 4th term in the sequence is -8.

Step-by-step explanation:

The nth term of the sequence B is given by:

B(n) = (-2)^{n-1}

So the fourth term will be given by:

B when n = 4, that is, B(4).

B(4) = (-2)^{4-1} = (-2)^{3} = -8

The 4th term in the sequence is -8.

Find each measure plz help
Rashid [163]

Answer:

m∠QRS = 52°

Step-by-step explanation:

From the given figure,

In right triangles ΔRQT and ΔRST,

QT = TS = 7.5 units [Given]

RT ≅ RT [Reflexive property]

ΔRQT ≅ ΔRST [By HL theorem of congruence]

Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]

m(∠QRS) = 2m(∠QRT)

               = 2×(26°)

               = 52°
