B infinite solutions,
Because both left hand and right hand sides are equal
Answer:
<h2>w² - 2(w)(1) + 1² = w² - 2w + 1 = (w - 1)²</h2>
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
We have
w² - 2w = w² - 2(w)(1)
We must add 1²
w² - 2(w)(1) + 1² = (w - 1)²
Answer:
15 gallons
Step-by-step explanation:
Given that:
Pumping rate is modeled by the equation :
Q(t)=45-t gallons per minute ; where t is in minutes
Number of gallons in tank after 30 minutes ;
Q(t)=45-t
Q(30) = 45 - 30
Q(30) = 15
Hence, Number of gallons in tank after 30 minutes is 15 gallons
Answer:
Rational
Step-by-step explanation:
The number comes to a stop (doesn't keep going), so it would be rational.
