Answer:
a[1] = 4
a[n] = -3·a[n-1]
Step-by-step explanation:
The sequence given is not a geometric sequence, since the ratios of terms are -3, -3, 3 -- not a constant.
If we assume that the last given term is supposed to be -108, then the common ratio is -3 and each term is -3 times the previous one. That is expressed in a recursive formula as ...
a[1] = 4 . . . . . . . . . . . first term is 4
a[n] = -3·a[n-1] . . . . . each successive term is -3 times the previous one
Answer: -1
Step-by-step explanation:
10^-3 x 10 = 10^-2
But you need it to be 1/10^3
So 10^-2 x 10^-1 = -2 + -1
= 10^-3
In order to put it in simplest form, the power needs to be positive.
So = 1/10^3
Meaning the missing power is -1
You can factor (x^3 and 6x^2) and (-4x and -24).
So x^2(x+6) - 4(x+6)
(x^2-4)(x+6)
(x-2)(x+2)(x+6)
Answer:
2
Step-by-step explanation:
OK 13-5=8 and that leaves 8k so k must be 2 because since their is no space they are being multiplied together and 8x2=16 :) hope this helps
plz give thanks
Answer:
135000
Step-by-step explanation:
first i took 200% of 54000 (54000 . 2) which is 108000
then found out the 50% which is 27000
then i added them and got 135000 :)
