It belongs to the set of real numbers
and as it can be written as a fraction then it is also a rational number.
We first integrate the expression to find the oil leaked since we have an expression for leakage rate.
Integrating:
O(t) = -10000exp(-0.2t); substituting t = 10
O(t) = -1,353 gallons
1,353 gallons of oil leak out in the first 10 seconds.
First you input the equation into the quadratic formula:
__________
x=<span><span><span>−<span>(<span>−2</span>)</span></span>±<span>√<span><span><span>(<span>−2</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(5)</span></span></span></span></span>

Next you simplify the formula:
___
x=<span><span>2±<span>√<span>−16
</span></span></span></span> ------------

This problem has no real solutions.
Answer:
5 : 30
Step-by-step explanation:
Note that 
× 10 = 5
Thus 3 × 10 = 30
Hence
: 3 = 5 : 30
