A barrel had 20 liters of water. Water leaked out from the barrel at a constant rate. After 24 hours, 14 liters of water was lef t in the tank. How many liters of water leaked out per hour? a.0.25 b.0.50 c.1.42 d.3.14
2 answers:
Let speed of water leaking out = x/h water left in the tank after 24h=20-(speedxtime) =20-(24x) =14 20-24x=14 24x=6 x=1/4 Therefore, answer is (a).
Step
<u>Find the amount of water that leaked out from the barrel</u>
Subtract liters from the total of water of the barrel
so
<u>Find the rate of liters of water leaked out per hour</u>
Divide the amount of water that leaked out from the barrel by hours
therefore
<u>the answer is</u>

U just add the exponents. b^8 x b^4 = b^12 hope this helps :)
Y = a(b^x) y=mx + b is the equation of a line. It is a linear function because it has a constant rate of change. y = a(b^x) is an exponential function because it has has an exponent and its rate of change is not constant
