Answer:

3072

Step-by-step explanation:

<u>General form of a geometric sequence</u>:

$a_n=ar^{n-1}$

where:

$a_n$ is the nth term
a is the first term
r is the common ratio

Given values:

first term, a = 3
common ratio, r = 4

Substitute the given values into the formula to create an <u>equation for the nth term</u>:

$\implies a_n=3(4)^{n-1}$

To find the 6th term, substitute n = 6 into the equation:

$\implies a_6=3(4)^{6-1}$

$\implies a_6=3(4)^{5}$

$\implies a_6=3(1024)$

$\implies a_6=3072$

Therefore, the 6th term of a geometric sequence whose 1st term is 3 and whose common ratio is 4 is 3072.

Can you please help me with this question?

Ray Of Light [21]

The answer is A, because function 2 is defined by y=(5/8)x-3, as function 1 is defined by y=(3/4)x+1, meaning that function 1 has both a greater rate of change and a greater y-intercept.
Answer: A.

Sally's $8,800 savings is in two accounts. One account earns 2% annual interest and the other earns 6%. Her total interest for t

sweet [91]

Answer:

In the 2% account, Sally has $2200 and in the 6% account, Sally has $6600.

Step-by-step explanation:

Suppose the amount invested at 2% is $X and the amount invested at 6% is $Y (assuming that the college student invested all his/her income on the two schemes). Therefore:

X + Y = 8800 (The sum of investments is basically the total income).

0.02X + 0.06Y = 440 (The sum of the interest received from the invested amounts is actually the total return).

Now solving these 2 simultaneous equations:

x + y = 8800 (Equation 1)

2x + 6y = 44000 (Equation 2)

From (Equation 1):

x = 8800 - y (Equation 3)

Put (Equation 3) in (Equation 2):

2(8800 - y) + 6y = 44000.

17600 - 2y + 6y = 44000.

4y = 26400

y = 6600.

To find x, substitute y = 6600 in equation 3. This gives:

x = 8800 - y.

x = 8800 - 6600.

x = 2200.

So in the 2% account, Sally has $2200 and in the 6% account, Sally has $6600!!!
