Which shows a function for the sequence 16, 8, 4, 2, …?
A. f(x)=16 ∙ (2) (^x−1)
B. f(x)=16 ∙ ( 1/3 ) ^(x−1)
C. f(x)=16 ∙ ( 1/2 ) ^(x−1)
D. f(x)=16∙ ( 1/4 ) ^(x−1)

C

Step-by-step explanation:

16, 8, 4, 2, …

a = 16

r = 8/16 = ½

f(x) = 16 × (½)^(x - 1)

i think the answer is true

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
