Answer:
Mid point is: (2.8;4.9)
Step-by-step explanation:
To find midpoint of a line segment we can use the general equation:

Where the point of the line are: (x₁;y₁) and (x₂;y₂).
In the problem, x₁ = 2.6, y₁ = 5.1 and x₂ = 3 and y₂ = 4.7. Replacing in the equation:

<h3>Mid point is: (2.8;4.9)</h3>
Answer:
The diameter would be 4.456338407...
Step-by-step explanation:
This is because if the formula for circumference is C= D(pi) , to find the diameter it's the opposite. D= C/pi

Answer:
The answer is 1/9 ⇒ the second answer
Step-by-step explanation:
* In the exponential functions we have some rules
(1) b^(-m) = 1/(b^m) (for all nonzero real numbers b)
- If we have negative power we reciprocal the base
to get positive power
(2) (b^m)^n = b^(mn)
- If we have power over power we multiply them
* In our problem: 
- At first change 27 to b^n
∵ 27 = 3 × 3 × 3 = 3³
∴ 
* Lets use rule (2)
∴
⇒ 3 × -2/3 = -2
* Use rule (1)
∴
⇒ reciprocal the fraction to change the sig of the power
* The answer is 1/9
