The function that is graphed is...
B.) y = |x - 3| - 4
Since the lines "|" in the function make it a V shape.
And when you graph the one point where the the 2 lines meet it is.
(-3, -4)
So this answer is correct. :P
Good Luck! :)
Answer:
D 21.80°
Step-by-step explanation:
Let x = measure of the angle
Tan x = 12000/30000 = .4
Arctan .4 = 21.80°
The length of one side is 17 meters because 68÷4=17. The 68 is 68 meters and 4 is how many sides a square has.
Answer:
The correct answer is 10 for lowest average cost and the cost function is 0.2
+ 75x + 20.
Step-by-step explanation:
Average cost function is given by = 
= C(x) = 0.2x + 
+75.
For minimizing we need to find 
C(x) = 0.
⇒ C(x) = 0.2 - 
.
⇒ = 0.2
⇒ = 100.
⇒ x = ±10
⇒ x = 10 ; cost cannot be negative.
Second order derivative is positive which implies the average cost minimizes.
Original cost function is given by C(x) × x = 0.2 + 75x + 20.
