Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive term in the sequence, that is
÷
= 3 ÷
= 30 ÷ 3 = 300 ÷ 30 = 10
This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a =
and r = 10 , thus
=

=
× 
= 3 ×
× 
= 3 × 
Thus
= 3
→ C
Answer:$344
1/5 of 400 is 80 so if you subtract that it would be $320
1/50 of $400 is 8 so if you multiply that by 3,3/50 of $400 is(8*3)24 so $320+$24=$344
Answer:
2 - √3
Step-by-step explanation:
tan45 = 1
tan60 = √3
2 tan 45 - tan 60
2(1) - √3
=> 2 - √3
Answer:
Step-by-step explanation:
1. (a-b-c) (a2+b2+c2-ab-ac-bc). = (a3-b3-c3).
NOTE : this is an identity 11th identity
2. (98)3
That is 98×98×98= 941192
For example. (1)3
That is 1×1×1= 1
Or (2)3
That is 2×2×2= 8. [ 2×2=4. ]. {4× 2 = 8 )
