one is the biggest common multiple. multiplying into 2 twice and 3 three times.
Answer:
Tan30° = 4/y
Tan30° = 1/root3
Therefore 4/y = 1/root3
Which gives the value of y 4root3
Which is 6.92 (approx)
As for x
Sin30 =4/x
1/2=4/x
X=8
The answer to the question is B.
<h3>

is the recursive formula of the geometric sequence</h3>
<em><u>Solution:</u></em>
<em><u>Given geometric sequence is:</u></em>
-0.6, 3 , -15, 75
We have to frame the recursive formula
Find the common ratio

Thus common ratio is -5
<em><u>The nth term of geometric sequence is given as:</u></em>

Where,
n is the nth term
a is the first term of sequence
r is common ratio
From sequence,
a = -0.6
r = -5
Therefore,

Where, n = 1 , 2 , 3 , 4 , .....
Thus the recursive formula is found
