The answer is a.  (-2, 4). The horizontal line is the x-axis, and the vertical line is the y-axis, so the coordinate points would be (x, y) and (-2, 4) fit those coordinates. Hope this helps! :)
        
                    
             
        
        
        
1 times 10 is 10. 10 times 10 is 100. So for those 3 models, the base is 10. All grids relate to the base 10 number system, because from left to right, the shaded part is getting bigger (increasing) by multiplying by 10. Hope this helps!

Answer:
f(n) = 2.8n + 0.7
Step-by-step explanation:
The form of the linear function is f(x) = m x + b, where
Let us solve the question
∵ The rule of the arithmetic sequence is a = 3.5 + 2.8(n - 1), where
 = 3.5 + 2.8(n - 1), where
- a is the nth term ⇒ output is the nth term ⇒ output
- n is the number of the term ⇒ input
→ To write it as a function replace a by f(n)
 by f(n)
∵ a = f(n)
 = f(n)
∴ f(n) = 3.5 + 2.8(n - 1)
→ Simplify the right side to make it in the form of the function above
∵ f(n) = 3.5 + 2.8(n) + 2.8(-1)
→ Remember (+)(-) = (-)
∴ f(n) = 3.5 + 2.8n - 2.8
→ Add the like terms in the right side
∵ f(n) = 2.8n + (3.5 - 2.8)
∴ f(n) = 2.8n + 0.7
 
        
             
        
        
        
Answer:
The maximum error in  calculating the surface area of the box is 152 square cm.
Step-by-step explanation:
We are given the following information in the question:
The dimensions of a closed rectangular box are measured  as 80 cm, 60 cm, 50 cm, respectively.
Possible error = 0.2 cm
Surface area of rectangular box = 

where l, b and h are the length, breadth and height of the rectangular box respectively.
Change in area =

Putting the values, we get,
Change in area =

The maximum error in  calculating the surface area of the box is 152 square cm.
