Answer:

1/4

Step-by-step explanation:

The common ratio in a geometric sequence is the number you multiply to previous term to get the term after.

Dividing by a number is the same as multiplying by that 1/number.

So the common ratio here is 1/4.

This is a geometric sequence since you are able to find all the terms in this sequence by multiplying 1/4 to it's previous term.

Examples:

160(1/4)=40

40(1/4)=10

10(1/4)=10/4=2.5

2.5(1/4)=2.5/4=0.625.

1. What is the formula for compound interest?

Rus_ich [418]

Answer:

1. CI = P (1 + $\frac{r}{100}$ )^ n - P

CI = A - P

Where P is Principal

R is interest rate

n is number of years

2. a. Semi annually - four times in a year

b. Monthly - two times in a year

c. annually - once in a year

Step-by-step explanation:

1. Money is said to be lent at compound interest , when the interest has become due at certain fixed period say, one year, half year, etc.., is given not paid to money lender, but is added to sum lent . The amount thus obtained become principal for next month and this process repeat until last period .

i.e CI = Final period - Initial period

or CI = A - P

or CI = P(1+ $\frac{r}{100}$ ) ^n - P

2. (a) Semi annually

A = P (1 + $\frac{r}{4 * 100}$ )^ n × 4

(b) Monthly

A = P (1 + $\frac{r}{2 * 100}$ ) ^ n × 2

A = P (1 + $\frac{r}{100}$ ) ^ n

The question is: "Without actually graphing, describe how the graph of y = ( -2^(x+17) ) - 4.3 is related to the graph of y = 2^

mojhsa [17]

Answer:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Step-by-step explanation:

When functions are transformed there are a few simple rules:

Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
Multiplying the function by a number less than 1 compresses it towards the x-axis.
Multiplying the function by a number greater than 1 stretches it away from the x-axis.
Multiplying by a negative flips the graph.

The graph of $(-2^{x+17}) -4.3$ compares to $2^x$ in the following ways:
