Answer:

Step-by-step explanation:
<u><em>The question in English is </em></u>
An expanding mobile phone company handled eight hundred and fifty thousand calls a day during the quarter. In the next quarter it expects to reach one million and increase quarterly by the same amount over the next two years. How many daily calls do you expect to handle in two years?
Let
x ----> the number  of quarter
y ---> number of daily calls
we know that
we have the points
(0,850,000) and (1,1,000,000)
Find the slope m

The linear equation that represent this situation is

How many daily calls do you expect to handle in two years?
In two years there are 8 quarterly
so
For x=8
substitute

 
        
             
        
        
        
We have 1 square with side length 8 inches, and 4 triangles with a base length of 8 inches and a height of 15.
Surface area = (8 × 8) + 4(0.5 × 8 × 15)
The first part of this equation is the area of the square
The second part is the area of a triangle, multiplied by 4 (because there are 4 triangles)
= 64 + 4(60)
= 64 + 240
= 304 in²
The total surface area is 304 square inches.
