your answer is incorrect. The correct answer is and
.
Step-by-step explanation:
If a quadratic function is and a>0, then minimum value of the function at point
.
The given function is
Here, a=1, b=b and c=182. So.
Put in the given function to find the minimum value of the function.
We know that minimum value is 13. So,
Taking square root on both sides.
The value of b is 26.
So, the given function is
Now, add and subtract square of half of coefficient of x.
On comparing with , we get
Therefore, your answer is incorrect.
A tank with capacity T gallons is empty. Tank will be filled in minutes
<u>Solution:</u>
Given, A tank with capacity T gallons is empty.
We have to find how many minutes will tank be filled?
Now, Water flows into the tank from pipe X at the rate of X gallons per minute,
And water is pumped out by pipe Y at the rate Y gallons per minute,
Then, together in one minute the amount of water filled will be x – y gallons [as X is greater than Y]
Now, the time take to fill tank =
Hence tank will be filled in minutes
