Answer:
<h2> 3600 barrels</h2>
Step-by-step explanation:
Step one
Given data
We are told that the rate of leakage is
60 barrels per minute
time = 1 hours= 60 minute
Required
The quantity of the oil that leaked after time = 1 hour= 60 minutes
Step two:
From
Rate=Quantity/time
Quantity= rate*time
Quantity= 60*60
Quantity= 3600 barrels
Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
