**HELP PLEASE** A geometric sequence has 32 as its first time and 1/2 as its fourth term. which of the following functions correctly expresses this relationship in terms of the nth term? a. f(n)=32+1/2(n-1)
b. f(n)=32+1/4(n-1)
c. f(n)÷32•1/2^(n-1)
d. f(n)=32•1/4(n-1)

WILL GIVE BRAINLIEST ​

what i would say the best answer is a. 40.5

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
