Answer:

19th term = ar^18

19th term = 774,840,978

Step-by-step explanation:

First term, a = 2

Common ratio, r = 3

nth term of a geometric sequence = ar^(n-1)

19th term = ar^(19-1)

19th term = ar^18

= 2 × 3^18

= 2 × 387,420,489

= 774,840,978

19th term = 774,840,978

Simplify 10 + 1/2 + 6 + 5/6 ​
Olenka [21]

Answer:

17 1/3

Step-by-step explanation:

10 + 6 + 1/2 + 5/6

Turn 1/2 into 3/3 =3/6

10 + 6 + 3/6 +5/6

10 +6 = 16

3/6 +5/6 = 8/6

Put 8/6 into mixed number than add it to 16

8/6= 1 2/6

Finally, add 1 2/6 and 16 it would equal 17 2/6 aka 17 1/3

Help..and give the right reasons and statement
m_a_m_a [10]

The triangles ΔAED and ΔCGF are similar to each other. Then angle ∠A is congruent to angle ∠C.

<h3>What is the SAS similarity theorem?</h3>

ΔABC is similar to ΔDEF  only if the ratio of two sides of ΔABC and the corresponding two sides of ΔDEF is equal and the angle included on both sides are congruent.

Suppose the two sides of ΔABC are AB and BC, and that of DEF is DE and EF, then for SAS similarity, we need

and

∠ABC = ∠DEF

In triangles ΔAED and ΔCGF,

AE = CF

AD = CG

∠E = ∠G = 90°

Then the triangles ΔAED and ΔCGF are similar to each other. Then angle ∠A is congruent to angle ∠C.

More about the SAS similarity theorem link is given below.
