What is the first term of the geometric sequence presented in the table below?
1 answer:
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:
2x+8
Step-by-step explanation:
2 times x = 2x. 2 times 4 = 8.
1. x + 2y -3 =0.
2. x/2 + y/9 = 1/3.
3. 4x-y+7=0.
4. x + y/2 = -1/2.
5. a. 3x-y-1=0.
b. x - y/3 = 1/3.
Answer:
yes
Step-by-step explanation:
because df is -2/3 and ac is -6/9 which is the same as -2/3
