Answer: she would be having $64 on the sixth day

Step-by-step explanation:

Each day,she doubles the number of dollars she saved on the previous day. This amount of money that she saves each day is increasing in a geometric progression. The formula for the nth term of a geometric progression is

Tn = ar^(n - 1)

Where

a is the first term of the sequence

r is the common ratio

n is the number of terms

To determine how much she saves on the sixth day,

n = 6

a = 2

r = 2

T6 = 2×2^(6 - 1)

T6 = 2 × 2^5

T6 = 64

A population is growing continuously at a rate of 5%. If the population is now 3400, what will it be in 17 years? Round to the n
Aleonysh [2.5K]

Answer:

In 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792

Step-by-step explanation:

Here we have that the formula for population presented as follows;

A = P(1+r)^t

Where:

A = Population after growth

P = Original population = 3400

r = 5% = 0.05

t = Time = 17 years

Population growing at a rate of 5% is thus given by the plugging in the above values into the population growth formula thus;

A = 3400 \times (1+0.05)^{17} = 7792.86

Since we are presenting data relating to number of people, we round alwys down as the statistics should represent the number of whole people on ground.

Therefore, in 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792.
