Answer:
Step-by-step explanation:
You know that Ozzie put 4 gallons of gas in his truck.
Notice the you must use:
Then, the first step is to make the conversion from gallons to quarts.
Since:
You get:
Finally, knowing the volume in quarts, you can make the conversion from quarts to liters. This is:
Therefore, Ozzie put 53.2 liters of gas in his truck.
Given:
One of the two roots of the given equation is double the additive inverse of the other.
To find:
The value of k.
Solution:
Let two roots of the given equation are and
.
According to the question,
(Additive inverse of
is
)
If and
are roots of the quadratic equation
then
We have,
Here, a =1, b=k and c=-98.
...(i)
Now,
Divide both sides by -2.
Taking square root on both sides.
Using (i), we get
Therefore, the value of k is either -1 or 1.
