Answer:
Step-by-step explanation:
we know that
To find the the rate per studen, we need to divide the total amout spent by the number of students
so
Let's start by first remembering what a "geometric sequence" is. A geometric sequence is a sequence of numbers that multiply by the same number each time. For example,
2, 4, 8, 16
is a geometric sequence since each number is multiplied by 2 from one to the next, but
2, 4, 6, 8
is NOT a geometric sequence. We are adding 2 each time, but not multiplying, so it doesn't count. We have to be multiplying to have a geometric sequence.
[A] Let's look at A, are we multiplying by the same thing?
6*3 = 18
18*3 = 54
54*3 = 162
162*3 = 486
Yes! We are multiplying by 3 each time. This is a geometric sequence!
[B] Are we multiplying by the same thing?
2*3/2 = 3
3*3/2 = 9/2 which is not 5.
NOPE
[C] Are we multiplying by the same thing?
2*5/2 = 5
5*5/2 = 25/2 which is not 8
NOPE
[D] Are we multiplying by the same thing?
-4*1/2 = -2
-2*1/2 = -1
-1*1/2 = -0.5
-0.5*1/2 = -0.25
-0.25*1/2 = -0.125
Yep, we are multiplying by 1/2 each time! This is a geometric sequence!
Answer:
x=6
Step-by-step explanation:
When we multiply exponents with the same base we add the exponents
When we divide exponents with the same base we subtract the exponents
4^3 * 4^3 ÷4^3 *4^3
We will work from left to right
Multiply means add
4^(3+3) ÷4^3 *4^3
4^6÷4^3 *4^3
Now divide means subtract
4^6÷4^3*4^3
4^(6-3)*4^3
4^3 *4^3
4^3*4^3
Multiply means add
4^(3+3)
4^6
4^6 = 4^x
The bases are the same so the exponents must be the same
x=6
