The profit in a business in one year was $35,000. what must be the profit the second year in order that the average for the two years may be $37,500?

Average of the 2 years is (year1+year2)/2

year1=35000
year2=?average=37500

so

(year1+year2)/2=37500
(35000+?)/2=37500
times 2 both sides
35000+?=75000
minus 35000 both sides
?=40000

the profit in 2nd year must be $40,000

Step-by-step explanation:

We are given the position function and need to find the value of t when h<17.

Create an inequality that represents this situation:

The "less than" sign makes this very specifically a conjunction problem as opposed to a disjunction. That's important to the solution. But we'll get there.

The simplest way to solve this is to subtract 81 from both sides:

then divide both sides by -16:

Notice now that the sign is facing the other way since we had to divide by a negative number. Now it's a disjunction. The solution set to this inequality is that t>2 or t<-2. First and foremost, time will never be negative, so we can disregard the -2. Even if that was t<2, the more time that goes by, the greater the time interval is, not the lesser. It's the "<" that doesn't make sense, not only the -2. The solution to this inequality is

t > 2 sec. That means that after 2 seconds, the height of the ball is less than 17 feet.
