Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive the email increases by a factor of 4 every 9.1 weeks, and can be modeled by a function, f(p) which depends on the amount of time, t (in weeks). Tobias initially sent the chain letter to 37 friends.

Write an exponential function describing this scenario. Use "^" to denote an exponent and "/" to denote a fraction sign.

•EXPONENTIAL MODELS IF THAT HELPS

f(p) = 37*4^(t/9.1)

Step-by-step explanation:

The generic model for an exponencial function is:

P = Po*r^t

Where P is the final value, Po is the inicial value, r is the rate and t is the time.

In our case, the function if f(p), the inicial value is 37, the rate is 4 for every 9.1 weeks and the time is t, in weeks.

As the rate occurs for every 9.1 weeks, we need to use this equation:

P = Po*r^(t/9.1)

This way, when t = 9.1, the rate will occur one time (will be r^1)

So, our final equation is:

f(p) = 37*4^(t/9.1)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
