Answer:
The answer to your question is z = 
Step-by-step explanation:
Process
I'll solve this problem using proportions, I hope it helps you
We consider the adjacent side of both triangle
Adjacent side small triangle = x Adjacent side big triangle = 10
Proportion of these sides = 
Now, consider the opposite side of both triangles
Opposite side fo small triangle = 2 Opposite side big triangle = x
Proportion = 
Now, equal both proportions and solve for x

x² = 20
x = 
x = 2
Using Geometric mean
x = 
Using the Pythagorean theorem to find z
z² = (√20)² + 2²
z² = 20 + 4
z² = 24
z =

Answer:
(a) The daily total revenue realized from the sale of 210 units of the toaster oven is $6,195.
(b) The additional revenue realized when the production (and sales) level is increased from 210 to 310 units is $1,400.
Step-by-step explanation:
The marginal revenue gives the actual revenue realized from the sale of an additional unit of the commodity given that sales are already at a certain level. The derivative <em>R'</em> of the function <em>R</em> measures the rate of change of the revenue function.
We know that the daily marginal revenue function is given by

(a) To find the the daily total revenue you must:
- Integrate the daily marginal revenue function,
,
where C is a constant.
- Find the value of C, using the fact that if you sell 0 units your daily revenue is $0.


The daily total revenue realized from the sale of 210 units of the toaster oven is
x = 210 units

(b) To find the additional revenue realized when the production (and sales) level is increased from 210 to 310 units you must:
- Find the daily total revenue realized from the sale of 310 units

The additional revenue realized when the production (and sales) level is increased from 210 to 310 units is

The answer is 7850 centimeters since 1m=100 cm. 78.5*100=7850
