Answer:

The sum of the left turns equals 360 degrees (the turtle has completely rotated around). In math terms, the sum of the external angles of a regular polygon is 360 degrees. Here, we have a 12-sided regular polygon which rotates until the image coincides with the preimage. That is 360/12 = 30 degrees (the outside angle). I think the angle is 30 degrees because the polygon has total of 360 degree then divide it to 12 then you will came up with a 30

2/3g + 1/2g = 14 multi step equations, i need help knowing the steps
MaRussiya [10]
Find the common denominator

It is 6

Multiply everything by 6

2/3*(6)= 4g

1/2 *(6)= 3g

14*(6)= 84

4g +3g = 84

7g= 84


g= 12

The population of a town grows at a rate proportional to the population present at time t. The initial population of 500 increas
Mazyrski [523]

Answer:

The population in 40 years will be 1220.

Step-by-step explanation:

The population of a town grows at a rate proportional to the population present at time t.

This means that:

P(t) = P(0)e^{rt}

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate.

The initial population of 500 increases by 25% in 10 years.

This means that P(0) = 500, P(10) = 1.25*500 = 625

We apply this to the equation and find t.

P(t) = P(0)e^{rt}

625 = 500e^{10r}

e^{10r} = \frac{625}{500}

e^{10r} = 1.25

Applying ln to both sides

\ln{e^{10r}} = \ln{1.25}

10r = \ln{1.25}

r = \frac{\ln{1.25}}{10}

r = 0.0223

So

P(t) = 500e^{0.0223t}

What will be the population in 40 years

This is P(40).

P(t) = 500e^{0.0223t}

P(40) = 500e^{0.0223*40} = 1220

The population in 40 years will be 1220.
