Fron the table given:
A3 = 112,
A8 = - 3,584
An = A1 *r ^ (n-1)
=> A3 = A1 (r^2) = 112
A8 = A1(r^7) = - 3,584
=> - 3584 / 112 = (r^7) / (r^2)
=> (r^5) = - 32
=> r = - 2
=> A1 (- 2)^2 = 112
=> A1 = 112 / 4 = 28
Answer: a1 = 28
Answer: D
Step-by-step explanation:
A seems complicated and doesn’t make an sense while D is simple
Uhhh , what are we suppose to answer here ?
Here is your answer:
1. These equations are similar because they "both share the same numbers but one is a decimal and the other is a whole number."
2. You have to solve each equation in order to determine which number is greater:
And:
Finally:
Therefore "8,464 is greater than 8.464."
Hope this helps!
