Eric cell phone service cost $40.00 a month for unlimited calls he also pays $0.02 for each text message he send. whichbis equat
Marianna [84]

Given :

Service cost , c = $40.

Amount paid for each message , m = $0.02 .

To Find :

Equation represents the total cost C in dollars for a month when eric send t text message.

Solution :

Let , total cost be C .

It is an linear equation with slope equal to 0.02 and y-intercept equal to 40.

So ,

C=mt+c\\\\C=0.02t +40

Hence, this is the required solution.

Answer:

-Exponential Decay

-Decay factor is (1-0.05)

Step-by-step explanation:

-Given that the number decreases by a defined rate each year from the initial size by 5%,

-This is an exponential decay function of the form:

y=Ae^{-rt}

Where:

y is the quantity/size after time t

A is the initial size

r is the rate of decay

-Our function can the be written as

y=45000e^{-0.05t}

Hence, the decay rate/factor is 0.05

#Alternatively

The exponential decay can be of the form:

y=ab^x

Where:

y is the size at time x, a is the initial size, x is time and b is the decay factor.

b is of the form b=(1-r),\ \  r=decay\  rate

y=ab^x\\\\y=45000(1-0.05)^x

Hence, the decay factor is (1-0.05)
