A social networking site currently has 7,000 actiave memembers.if the site loses 5% of its active members, each month, determine the range and domain of this situation

see the explanation

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

where

y is the number of active members

x is the number of months

a is the initial value (y-intercept)

r is the rate of change

we have

substitute

The domain of the function is the interval [0,∞)

Remember that the number of months cannot be a negative number

Te range of the function is the interval (0,7,000]

Packages A and C

Step-by-step explanation:

To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.

Package A =  3 : 30

Package B = 5 : 60

Package C = 12 : 120

Package D = 16 : 120

Now let's break it down.

Package A = 30/3 = $10 per lift

Package B = 60/5 = $12 per lift

Package C = 120/12 = $10 per lift

Package D = 120/16 = 7.5 per lift

So now we are able to know which packages have the same ratio.

Package A and C cost $10 per lift.
