Answer:
B. 2x + 9y = 18
Step-by-step explanation:
If the diameter is d = 8, then we divide that in half to get the radius of r = 4.
If the radius is r = 9, then we double it to get the diameter of d = 18
The formulas are:
- radius = diameter/2
- diameter = 2*radius
I'll let you determine the others.
Answer:
h(-8) = -18
Step-by-step explanation:
It is given that,
h(t)=-2(t+5)^2 --------(1)
<u>To find h(-8)</u>
Substitute t = -8 in equation (1)
h(-8) = -2(-8 + 5)^2
h(-8) = -2(-3)^2
h(-8) = -2 x 9 = -18
therefore the value of h(-8) = -18
But there is no option with value h(-8) = -18

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.
