The eight term of a geometric progression is given by Sn= -[-3(sin^2x + cos^2x)^n + In e. Find the first term and common ratio.​
igor_vitrenko [27]

Answer:

Step-by-step explanation:

Sn= -[-3(sin^2x + cos^2x)^n + In e.

sin^2x + cos^2x = 1  and ln e = 1, so

Sn = -(-3)^n + 1

When n = 8

this = -(-3)^8 + 1

Perform the indicated operation. 4/11÷ 4/9
nordsb [41]

The answer you are looking for is 9/11.

When dividing fractions, you multiply the first value by the inverse of the second value. The inverse is found by simply flipping the numbers of the last fraction. So, the inverse is 9/4. Then, multiply 4/11 and 9/4 to get 36/44. 36/44 simplified (divided by 4/4) is 9/11. Thus making 9/11 the answer.

I hope this helps.
