Answer:
(a) x > 4 (b) y < -2
Step-by-step explanation:
Domain is referring to the x-values while the range is referring to the y-values.
Since the function (the line) has a circle at the point (4, -2), the function will be exclusive at that coordinate.
The line goes to infinity for the x-values from 4, so you write x > 4 or ∞ > x > 4.
Similarly, the line goes to infinity for the y-values from -2, so you write y < -2 or -∞ < y < -2.
Answer:
(P-12)/2 = L
Step-by-step explanation:
1. Start off with an equation in terms of perimeter
P = (2)(6) + (2)(L)
2. Multiply the two and the six
P = 12+ (2)(L)
3. Move the terms around so only "L" is on one side
(P-12)/2 = L

Answer:
12 years
Step-by-step explanation:
From the formula;
A = P(1 + r)^n
A = Amount = $2733.19
P = Principal = $2150
r = rate = 2%
n = time in years = ???
2733.19 = 2150(1 + 0.02)^n
2733.19/2150 = (1 + 0.02)^n
1.27 = (1.02)^n
Taking logarithm of both sides
log 1.27 = n log 1.02
n= log 1.27/log 1.02
n= 0.1038/0.0086
n = 12 years
Answer:
y=7
Step-by-step explanation:
Since y "b" of the triangle is x and the hypotenuse is 2x, you can divide 14 by 2 and get 7, the answer.
Answer: Second option is not true for a firm in perfect competition.
Step-by-step explanation:
We know that
In perfect competition, number of buyers and sellers are in large number, free entry and exit of firms, it sells homogenous products and can't earn abnormal profit.
In this competition, "Firm is the price taker, industry is the price maker".
and AR = MR as there is constant price fixed by the industry.
Hence, Second option is not true for a firm in perfect competition.
