A bacteria grows exponentially so that it doubles every 12 days. There are 500 bacteria initially. Write a function that models the number of bacteria after t days.

Note is is NOT doubling every day! Careful.

Find the number of bacteria after 60 days.

Answers

Answer 1

Answer:

16000 bacteria after 60 days

Step-by-step explanation:

60 divided by 12 = 5

500 x 2= 1000

1000 x 2 = 2000

2000 x 2 = 4000

4000 x 2 = 8000

8000 x 2 = 16000

Answer 2

The function is, f(x) =  2x/12*t

And, the number is 16000 bacteria after 60 days.

What is function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, given that,

A bacteria grows exponentially so that it doubles every 12 days

let, initially the number of bacteria = x

after 12 days = 2x

i.e. after t days = 2x/12*t

So, the function is, f(x) =  2x/12*t

Now, we have,

60 divided by 12 = 5

So, the number of bacteria will be,

500 x 2= 1000

1000 x 2 = 2000

2000 x 2 = 4000

4000 x 2 = 8000

8000 x 2 = 16000

Hence,   the number of bacteria after 60 days is 16000.

Given that y varies directly with x, use the specified values to write a direct 1 point
variation equation that relates x and y. x = 24 y=-6*

Answers

Answer:

y = - [tex]\frac{1}{4}[/tex] x

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 24, y = - 6

- 6 = 24k ( divide both sides by 24 )

[tex]\frac{-6}{24}[/tex] = k , that is

k = - [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex] x ← equation of variation

Basically it’s 40 miles

Answer:

The answer is D, about 40 miles.

Use the pythagorean theorem.

Distance between Seaside & Landview: 6

Distance between Landview & Oceanfront: 5

Answers

Answer:

Option 3

Step-by-step explanation:

the symbol your question is showing is "greater than or equal to"

when a line includes "or equal to", the circle will be filled in. also, since the symbol is going towards 5, it is considered a greater than symbol. so, you'd want to choose the option with a filled in circle and an arrow pointing to the right.

since option 3 has a filled in circle and has its arrow pointing towards the positive (or right) side of the line, it should be option 3.
