Select the correct answer.
what is the value of (4 x (1/2)-1).
what is the value of t=1

For this case we must substitute the values t = 1,2,3 in the given series:

For

For :

For :

We add:

So, the value is 7.

Option C

Option C.

Step-by-step explanation:

The given expression is

We have to find the sum of 3 terms of the sequence formed.

The given sequence is a geometric sequence.

Explicit formula for this sequence is in the form of

In the given formula first term a = 4

and common ratio r =

Sum of a geometric sequence is represented by the expression,

Therefore, Option C is the answer.

c

step-by-step explanation:

at least i think its

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
