Answer:
k = 12
Step-by-step explanation:
Given:
The equation 
To find:
Value of
for which the given equation has one distinct real solution.
Solution:
The given equation is a quadratic equation.
There are always two solutions of a quadratic equation.
For the equation:
to have one distinct solution:

Here,
a = 2,
b = -k and
c = 18
Putting the values, we get:

The equation becomes:

And the one root is:

The jeep gets 22 miles per gallon...
he has 5 gallons in the tank already....
buys gas at 1.25 per gallon.....spends $ 22...so he buys 22 / 1.25 = 17.6 gallons
so he has a total of (5 + 17.6) = 22.6 gallons....at 22 miles per gallon =
22.6 * 22 = 497.2 miles <==
Answer:
Step-by-step explanation:
274.04/34=8.06(21)=169.26
Answer:
No Side Is Being Favored Since The Die Is A Fair Six-Sided Die.
So Each Number Has The Same Chance Of Being Rolled.



which means either

or

. The equation has no solution, since

is always bounded between -1 and 1. The second has one solution at

, and any number of complete revolutions will also satisfy this equation, so in general the solution would be

where

is any integer.
So you could choose

and

.
