Answer:
28 cm
Step-by-step explanation:
Given that :
Area = 791 cm
Base, b1 = 26.5 cm
Base, b2 = 30 cm
Area, A of trapezoid :
A = 1/2 (a + b) h
Where a and b are the bases ;
791 = 1/2(26.5 + 30)h
791 = 0.5(56.5)h
791 = 28.25h
h = 791 / 28.25
h = 28 cm
Answer:
-24x^7
Step-by-step explanation:
Note that (-2)^3 = -8, and so:
(-2 x^2 )^ 3 ·3 x = -8*x^6 * 3*x, or -24x^7

Answer:
z =86
Step-by-step explanation:
The exterior angle of a triangle is the sum of the opposite interior angles
z + z-39 = z+47
2z-39 = z+47
Subtract z from each side
z-39 = 47
Add 39 from each side
z = 47+39
z =86
The marginal revenue of selling the eighth unit is $-4.
A monopolist is the only producer in the industry. A monopolist operates in a monopoly. The monopolist sets the market price of their products.
Marginal revenue is the change in total revenue when quantity sold increases by one unit.
Marginal revenue = change in total revenue / change in quantity sold
change in total revenue = ($3 x 8) - ($4 x 7) = $-4
change in quantity sold = 8 - 7 = 1
Marginal revenue = $-4 / 1 = $4
