Answer:
3.5
Step-by-step explanation:
I recommend using a calculator. Divide 7/2.
The simplified form of the function will be (√10 - √10 + √15 - √21 ).
<h3>
What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The expression will be calculated as:-
(√2 + √3 ) ( √5 - √7 ) = √2 (√5 + √7 ) + √3 ( √5 - √7 )
= √2√5 + √2√7 + √3√5 - √3√7
= √10 + √14 + √15 - √21
Therefore simplified form of the function will be (√10 - √10 + √15 - √21 ).

The mean of a sequence of numbers is the average.
The true statement is: 
The given parameters are:
The mean of a dataset is calculated as:
So, we have:
Multiply both sides by m
When the sequence is split into two, we have:
Where:
So, we have:
Hence, the true statement is:

Answer:
Maximum
Step-by-step explanation:
dy/dx = 4 - 4x³ = 0
x³ = 1
x = 1
y = 4 - 1 = 3
There's only one stationary point: (1,3)
Nature:
d²y/dx² = -12x²
x = 1, so -12
Negative means it's maximum turning point
