Answer:
b. a unique real solution
Step-by-step explanation:
A quadratic equation ax² + bx + c = 0 ,
Has two distinct real roots,
If discriminant,
Has two equal real roots,
If D = 0,
Has two imaginary roots or no real roots,
if D < 1,
Here. the given qudratic equation,
By comparing,
a = 4, b = 32, c = 64,
Hence, the equation has two equal real roots or a unique real solution.
i.e. OPTION 'b' is correct.

Answer:
<h2>x = 1.58</h2>
<u>Step-by-step explanation:</u>
base = X
hypotenuse = √5
cos 45° = base / hypotenuse
1/√2 = X / √5
X = √5 / √2
X = 1.58
Answer:
Finite Set
Step-by-step explanation:
A finite set is a set that contains a fixed number of elements, that is, the elements are countable. However, the opposite of a finite set is an infinite set which does not have a fixed number of elements and is uncountable.
Examples of a finite set are
- The set of all past American Presidents
- The set of all persons in China
- The set of birds in Australia
