Two of the most dangerous animals in the enchanted forest are snakes and bears. The population of bears began with 100 bears in

the year 2000 and increases at a rate of 4 bears per year. The population of snakes began at 1 snake in the year 2000 and doubles every year.
Do you think the population of snakes will ever catch up to the population of bears? Why or why not?
If you answered yes, how many years do you think it would take for snakes to outnumber bears?

Answer:

Yes

IT WILL TAKE 8 YEARS.

Step-by-step explanation:

Bear starting population = 100

Bear population rate = 4 per year

Snake starting population = 1

Snake population rate = doubles every year

Bear population model:

y = 4x+100

Where y = new bear population

x = number of years after year 2000

Snake population model :

y = 2^x

Where y = new snake population

x = number of years after year 2000

THE POPULATION OF SNAKES WILL CATCH UP WITH THAT OF BEARS BECAUSE AFTER 7 YEARS THE POPULATION WILL BE EVEN.

After 7 years :

Bear population :

y = 4x + 100

y = 4(7) + 100 = 128

y = 128

Snake population :

y = 2^x

y = 2^7

y = 128

Using random guess in the both models :

After 8 years :

Bear population :

y = 4x + 100

y = 4(8) + 100 = 132

y = 132

Snake population :

y = 2^x

y = 2^8

y = 256

The 3kg object in Figure is released from rest at a height of on a curved frictionless ramp.
yanalaym [24]

The object compresses the spring up to 0.8577m.

<h3>What is Potential Energy?</h3>

Potential Energy is the energy possessed by an object at rest.

The object is falling from the rest and it is assumed that the friction on the ramp is zero and the air resistance is also considered to be zero so only the gravitational force acts and the total potential energy gets converted to Kinetic Energy.

The total amount of potential energy at the top of the ramp is given by

Ep=mgh

Ep=3 * 9.81 *5

Ep=147.15 Joules

This is equal to kinetic energy.

From the formula for elastic potential energy

The distance up to which the spring is compressed is determined

The force constant = 400N/m

147.15 =(1/2)k(x²)

294.3=(400)(x²)

0.73575=x²

x=0.8577 m

So, the object compresses the spring up to 0.8577m.

  • When the object compresses the spring, the potential energy of the spring is converted into Kinetic Energy so it will push the object back again.

Explain how you know that 0.38 is a rational number?
dangina [55]

Answer:

0.38 is a rational number because it can be expressed as fraction, and it isn't a repeating decimal.

Step-by-step explanation:

Repeating decimals aren't rational, and all rational numbers can be expressed as a fraction, or they aren't rational.
