Answer:
A
Step-by-step explanation:
Recall that for a quadratic equation of the form:
The number of solutions it has can be determined using its discriminant:
Where:
- If the discriminant is positive, we have two real solutions.
- If the discriminant is negative, we have no real solutions.
- And if the discriminant is zero, we have exactly one solution.
We have the equation:
Thus, <em>a</em> = 2, <em>b</em> = 5, and <em>c</em> = -<em>k</em>.
In order for the equation to have exactly one distinct solution, the discriminant must equal zero. Hence:
Substitute:
Solve for <em>k</em>. Simplify:
Solve:
Thus, our answer is indeed A.
The value of the 
and 
are 0 and 1.153 .

What is the limiting value of a function?</h3>
Limiting Value of a Function. The function's limit is the value of the function as its independent variable, such as x approaches a certain value called the limiting value. For simple equations, this is similar to finding out the value of y when x has a unique value.
Given that,
f(x) = 
First to calculate the limit value of the given function at x=0.
= 
= 4×0×1 (∵ cos0 = 1)
= 0
Similarly,
= 
= 4×
×cos
= 4××
(∵cos60° = )
= 1.153
Hence, The value of the and are 0 and 1.153.

Answer:
the Palo Duro Canyon is found in the Great Plains of Texas.
Answer:
14
Step-by-step explanation:
If he had 14 then he gave away 6, he'd have 8. 8 plus 4 is 12. He had 14 before giving any away.
X^5 (X to the fifth power) - 4 (x^5 - 4)
