A submarine started at 750 meters below sea level. It rose 50 meters per hour over a 4-hour period. Which expression represents
Cerrena [4.2K]

Answer:

y(t) = 750 -50t

Step-by-step explanation:

We want to model the position of the submarine as a function of time.

Notice that we have a constant amount. The initial depth: 750 meters

 Then we have a factor that varies over time. Every hour the submarine ascends 50 meters. therefore as t increases the depth y(t) of the submarine decreases. Then the factor is:

-50t.

Where t represents the time in hours.

Then the equation that represents the new position of the submarine in relation to the level of the sea:

y(t) = 750 -50t

As accounts manager in your company, you classify 75% of your customers as "good credit" and the rest as "risky credit" dependin
Elena-2011 [213]

Answer:

The percentage of overdue accounts are held by customers in the "risky credit" category is 62.5%

Step-by-step explanation:

Customers in the "risky" category (25% of total accounts) allow their accounts to go overdue 50% of the time on average.

That means that on average, 12.5% of total accounts is overdue.

0.25*0.50 = 0.125

In the "good credit" category only 10% goes overdue. That means 7,5% of total accounts goes overdue in this category.

0.75*0.10=0.075

The total accounts that go overdue is 0.125+0.075 = 0.200.

The percentage of overdue accounts held by customers in the "risky credit" category is:

0.125/0.200 = 0.625 or 62.5%
