Write an equation to represent the relationship between the step number, n, and the number of dots, y.
KengaRu [80]

The equation that represents the relationship between step number and the number of dots is y=5^n.

Solution:

Let the number of dots be y.

Step number 0: Number of dots = 1

y = 1

Using exponential rule: a^0=1

y=5^0

Step number 1: Number of dots = 5

y = 5

y=5^1

Step number 2: Number of dots = 25

y = 25

y=5^2

Step number 3: Number of dots = 125

y = 125

y=5^3

Note that in step number 0 the power is 0, 1st step power of 5 is 1, 2nd step power of 5 is 2 and the third step power of 5 is 3.

If the process goes on up to n steps, then power of 5 is n.

∴ Step number n:

y=5^n

Number of dots = 5^n.

Hence the equation that represents the relationship between step number and the number of dots is y=5^n.

Find the amount accumulated if $50000 is invested for 20 years at a rate of 7% compunded daily?
pickupchik [31]
So to find this we need to use the compound interest formula which is A=P(1 + r/n) ^nt
P = principal amount
R = percentage rate
N = number of times it is compounded yearly
T = time

So you plug in the numbers for the formula

50,000(1 + 0.07/ 365) ^0.07*365

The answer would be $202,732.78
I hope this helps :)
