Answer:
first we find the common difference.....do this by subtracting the first term from the second term. (9 - 3 = 6)...so basically, ur adding 6 to every number to find the next number.
we will be using 2 formulas....first, we need to find the 34th term (because we need this term for the sum formula)
an = a1 + (n-1) * d
n = the term we want to find = 34
a1 = first term = 3
d = common difference = 6
now we sub
a34 = 3 + (34-1) * 6
a34 = 3 + (33 * 6)
a34 = 3 + 198
a34 = 201
now we use the sum formula
Sn = (n (a1 + an)) / 2
S34 = (34(3 + 201))/2
s34 = (34(204)) / 2
s34 = 6936/2
s34 = 3468 <=== the sum of the first 34 terms:
Answer:
375
Step-by-step explanation:500 equals 100% divide by 4 its 125 times 3 equals 375, your welcome
Answer:

Step-by-step explanation:
Using the trigonometric identities
secx = 
, cosecx = 
cotx = 
, tanx = 
Consider the left side
secA cosecA - cotA
= 
× 
- 
= 
-
= 
= 
( cancel sinA on numerator/ denominator )
= 
= tanA = right side ⇒ proven
Answer:
Step-by-step explanation:
This number is much larger than 1. You need to start at the decimal and move left (that's how scientific notation works for numbers larger than 1.)
So the answer is 1.0054 * 10 ^7
The person doing this started at the 1 and moved right until he/she hit the decimal. Wrong direction.
