Angle B = 68 degrees
Using the Law of Sines
b / sin(B) = c / sin (C)
b = sin (68) * c / sin (49)
b = 0.92718 * 3 / 0.75471
b =

Step-by-step explanation:
ANSWER
The set of the intersection of {
} and {
} is
{
}
EXPLANATION
Let 
{}
and
{}.
The intersection of the two sets are the elements that are in both set A and set B.
The elements that are common to both sets are 2 and 5. So, we write;
{}
Therefore the correct answer is C
Answer:
(x + 2)^2 - 1
Step-by-step explanation:
x^2 + 4x + 1
= (x^2 + 4x + 2 - 2 + 1)
= (x + 2)^2 - 1
Answer:
A) A = 1; B = 0; C = 20
Step-by-step explanation:
The standard form for a quadratic is
Ax^2 +Bx +C=0
We are given
1/4x^2 + 5 = 0
Rewriting
1/4x^2 +0x+ 5 = 0
A = 1/4 B=0 C=5
We can multiply each side by 4
4(1/4x^2 +0x+ 5) = 0*4
x^2 +0x+ 20 = 0
A = 1 B=0 C=20
