For a geometric sequence with common ratio
, we have
that is, the
-th term in the sequence is the product of the previous term and the common ratio
. So
Then the sum of the first 7 terms is
Notice that
so we can subtract this modified sum from
to get
We're told that
and
, so the sum of the first 7 terms is
Answer:
8 ft
Step-by-step explanation:
The area of a paralellagram is b*h. Since we know the base, 15, we can plug this into an equation.
15(h) = 120.
Divide by 15 on both sides to get you 8.
Answer:
(8-(4*2)) / 1 =0
Step-by-step explanation:
(8-(4*2)) / 1 =0
Answer:
(- 19, - 11, 5, 25)
Step-by-step explanation:
The given function is f(x) = 4x - 7
Now, we have to find the range of the given function for the given domains.
The domains are given as (2 - 5, - 1, 3, 8) i.e. (- 3, - 1, 3, 8).
Therefore, f(- 3) = 4(- 3) - 7 = - 19
f(- 1) = 4(- 1) - 7 = - 11
f(3) = 4(3) - 7 = 5
f(8) = 4(8) - 7 = 25
So, the ranges of the function are (- 19, - 11, 5, 25) (Answer)
The exponent for that would be 13^3.
If the answer is incorrect, then i am sorry.
