So -r/4<u><</u>8
treat it as kind of an equal sign so do the sam eto both sides
multily both sdies by 4 to gert rid of fraciton
-r<u><</u>32
multiply by -1
remember when multipy by -1 flip the sign
r<u>></u>-32
The 11th term is 2, 095, 152
Explanation:
This is a geometric sequence, since each term after the first is obtained by multiplying a common ratio,
r
.
The common ratio is
4
. The first term,
a
, is
2
. The number of terms,
n
is
11
.
We use the formula
t
n
=
a
×
r
n
−

to determine the nth term in a geometric sequence.

Hopefully this helps!
Answer:
- 15
Step-by-step explanation:
The answer is for 1st question is “10.4” and for the second question “non of these choices are correct”.
Explanation:
For the 1st question:
tan = opposite / adjacent
tan 30 = x / 18
18 tan 30 = x
x = 10.4
For the 2nd question,
If a triangle as an angle of 90 degree, it is 100% a right triangle.
Hope it helps :), mark me brainliest please!
