As already described above, the prime polynomial is that which can no longer be factored to yield a much simpler terms. From the given choices, that which cannot be factored is letter C.
Answer:
The correct answer is 10 units.
Step-by-step explanation:
Profit function of a small business is given by P(x) = 0.3
+ 7x - 40, where x is the number of units sold.
The small business intend to make a profit of $60.
To find out the number of units the business has to sell in order to have a profit of $60 is given by,
P(x) = 0.3
+ 7x - 40 = 60
⇒ 0.3
+ 7x - 100 = 0
⇒ 3
+ 70x - 1000 = 0
⇒ x = -70 ±
× 
⇒ x = -70 ± 130 × 
⇒ x = 10 or -
Quantity sold cannot be negative giving us the value of x as 10 units.
I’m pretty sure it’s B. -3/8x - 1/4 :).
60 seconds in a minute, but if you divide 60/3, you’ll get 20. So 20*4=80 gallons/min. If you multiply 80*60=4,800 gallons/hr
