D will be The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
Answer:
1. b. 2. a. 3. a.
Step-by-step explanation:
1. (f + g)x = f(x) + g(x)
= x^2 + 2x + 4
(f + g)(-1) = (f + g)(x) where x = 1 so it is
(-1)^2 + 2(-1) + 4
= 1 - 2 + 4
= 3.
2. We find (f o g)(x) by replacing the x in f(x) by g(x):
= √(x + 1) and
(f o g)(3) = √(3 + 1)
= √4
= 2.
3. (f/g) c = f(x) / g(x)
= (x - 3)/(x + 1)
The domain is the values of x which give real values of (f/g).
x cannot be - 1 because the denominator x + 1 = -1+1 = 0 and dividing by zero is undefined. So x can be all real values of x except x = -1.
The domain is (-∞, -1) U (-1, ∞)

Step-by-step explanation:
I think you just multiply the numerator by the resipical of the denominator.
Answer:
I believe it is A, d= 6t
It is an odd question though.
-2/5
Step-by-step explanation:
(Im pretty sure although I haven't studied this in a long time. Absolute value is the opposite of a specified x value)
