What are algebraic expressions?
- In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
- Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is a right circular cone that has a height of 2.6 in and a base with a diameter of 5.7 in.
The volume of a right circular cone is -
V = {πr²h/3}
V = {π(d/2)²h/3}
V = {πd²h/12}
V = {3.14 x 5.7 x 5.7 x 2.6}/12
V = 22.11 in³
Therefore, the volume of a right circular cone is 22.11 in³.

Which statements could he include in his explanation? Check all that apply.
The domain of both functions is all real numbers.
The domain of f(x) is x > 5.
The domain of g(x) is x > 5.
The range of both functions is y > 5.
The range of f(x) is y > 0.
The range of g(x) is y > 0.

Answer:
Hence, option 1 is correct.
Hence, last option is correct.
Step-by-step explanation:
We have given two function
and
Domain is the values x can take and
And range is the values y can take
Hence, x can take any real value in both the functions in f(x) and g(x)
Hence, option 1 is correct
Now, for range
range of f(x) can be any real number
But range of g(x) can be positive number
Hence, last option is correct.
Rest all options are incorrect.
- The domain of both functions is all real numbers.
- The range of g ( x ) is y > 0

Mathew is going to cover the patio with paving slabs. Each paving slab is a square of side 60cm.
Mathew buys 32 of the paving slabs.
A) Does Mathew buy enough paving slabs to cover the patio?
The paving slabs cost £8.63 each
B) Work out the total cost of the 32 paving slabs.
Answers
if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio and £276.16 is the total cost of the 32 paving slabs.
What is a Rectangle ?
A rectangle is a polygon with 4 sides , in which opposite sides are parallel and equal .
It is given that the patio has length of 3.6 m and width of 3 m
Each paving slab is a square having side 60 cm or .6 m
Area of a rectangle is given by
length * width
3.6*3
10.8 m²
Area = 10.8 m²
Area of a slab = 0.6 *0.6 = 0.36 m²
No. of slabs needed = n
10.8 = 0.36* n
n = 30 slabs
So if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio.
If the paving cost costs £8.63
The total cost for 32 slabs will be 32 * £8.63
= £276.16
