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

I need help I don't understand it at all
DedPeter [7]

Answer:

x = 9

Step-by-step explanation:

Given

5x - 31 = 23 - x ( add x to both sides )

6x - 31 = 23 ( add 31 to both sides )

6x = 54 ( divide both sides by 6 )

x = 9

PLS HELP 20 points and brainliest
4vir4ik [10]

Answer:Since the volume of a cylinder formula involves the radius, you can solve for the radius and double it to find the diameter.

Write the formula. Volume=π⋅radius2⋅height.

Substitute the dimensions of the shape into the formula. Use 3.14 as the value for π. 791.28=3.14⋅r2⋅28.

Solve the equation for the variable.

A rope 16 feet long is cut into two pieces. one piece is used to form a circle and the other used to form a square. find a funct
givi [52]
Circumference of Circle=C, =2(pi)(radius)
Radius of Circle=r
Side of square=x
f(x)=area of circle
g(r)=area of square
16 feet=C+4x
C=16-4x
2(pi)(r)=16-4x
2(pi)(r)=2(8-2x)
(pi)(r)=8-2x
r=(8-2x)/(pi)
x=(8-(pi)r)/2
f(x)=(pi)(r^2)
f(x)=(pi)((8-2x)/(pi))^2
f(x)=((8-2x)^2)/(pi)
f(x)=((64-32x+4x^2))/(pi)
g(r)=((8-(pi)r)/2)^2
g(r)=((64-16(pi)r+(pi)^2(r^2))/4

Domain and range, please help and explain this to me Jim, thanks!!!
SpyIntel [72]

Answers:

Domain = {-24, -6, -4, 4, 21, 47}

Range = {24, 55, 45, 77, 3, 93}

Don't forget about the curly braces.

The domain is the set of all allowed x inputs. So we simply list all the x coordinates of the points given. That's all there is to it. The range is the list of all possible y output values, so we just list the y coordinates. Toss out any duplicate y values. Sorting each set is optional because order doesn't matter in a set.
