Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².

To figure this question out, I recommend the FOIL method.
F: First
O: Outer
I: Inner
L: Last
Statement A is true. IH and AG in the FOIL method is the Outer.
Answer:
Demand is inelastic at p = 9 and therefore revenue will increase with
an increase in price.
Step-by-step explanation:
Given a demand function that gives <em>q</em> in terms of <em>p</em>, the elasticity of demand is

- If E < 1, we say demand is inelastic. In this case, raising prices increases revenue.
- If E > 1, we say demand is elastic. In this case, raising prices decreases revenue.
- If E = 1, we say demand is unitary.
We have the following demand equation
; p = 9
Applying the above definition of elasticity of demand we get:

where
- p = 9
- q =



Substituting the values


Demand is inelastic at p = 9 and therefore revenue will increase with an increase in price.
