Answer:
is the distance between the point A and point B.
Step-by-step explanation:
Let
A ≡ (x₁, y₁) ≡ (-9 , -8 )
B ≡ (x₂, y₂) ≡ (-6 , -4 )
Now by Pythagoras Distance formula we have
a² + b² = c²

The sum of 3.0478 and 4.92 is
, which have 5 significant digits.
<u>Step-by-step explanation:</u>
We have ,
and
. The significant digits of a number are digits that includes all digits except:
- All leading zeros. For example, "013" has two significant figures: 1 and 3;
- Trailing zeros when they are merely placeholders to indicate the scale of the number and ,
- Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment supports.
Here
and with significant digit rules
. Now, Sum of both numbers = 
⇒Sum of both numbers = 
⇒Sum of both numbers = 
∴ The sum of 3.0478 and 4.92 is
, which have 5 significant digits.
Given
piece of plywood measuring 2 feet 8 inches long by 2 feet 4 inches wide.
What is the area of a piece of plywood .
To proof
Here plywood shape in the form of rectangle.
Formula
Area of rectangle = Length×Breadth
As given in the question
Length =2 feet 8 inches
Breadth = 2 feet 4 inches
First convert feet into inches
1 feet = 12 inches
2 feet 8 inches = 2×12 + 8
= 32 inches
Also
2 feet 4 inches = 2×12 +4
= 28 inches
put is in the above formula
Area of plywood = 32 ×28
= 896 inches²
Therefore option (b) is correct
Hence proved
