Answer:
4092
Step-by-step explanation:
r = 2
a1 = 4×(2)^(1 - 1) = 4
S10 = a1×((1 - r^10)/(1 - r)
= 4×((1 - 2^10)/(1 - 2))
= 4×((1 - 2^10)/-1)
= 4×(-(1 - 2^10))
= -4×(1 - 2^10)
= -4 + 4 × 2^10
= -4 + 2^2 × 2^10
= -4 + 2^12
= -4 + 4096
= 4092
A is true. Thus D is also true. The result of the synthetic division shows C is true.
The appropriate choices are ...
A. (x - 2) is a factor of 3x² - 11x + 10
C. (3x² - 11x + 10) ÷ (x - 2) = (3x - 5)
D. The number 2 is a root of F(x) = 3x² - 11x + 10
