What grade are u? I'm just asking cause the formulas are going with grade I could help if u want me too
The relation between A and B subset is A⊆B
What is Subsets?
A set "X" is said to be the subset of "Y" is each elements of X is present in Y and is denoted by X⊆Y.
It should be noted that In roster notation, the use of the {" and "} character indicates that a set of numbers is a collection of elements, which can either be a finite or infinite collection.
Thus in the given question :
A={summer, autumn, spring, winter}
B={summer, winter}
"summer" and "winter" elements of B which is common and also presents in A therefore, B is subset of A and is denoted as A⊆B.

Answer:
; minimum
Step-by-step explanation:
Given:
The function is, 
The given function represent a parabola and can be expressed in vertex form as:
The vertex form of a parabola is 
, where, 
is the vertex.
So, the vertex is .
In order to graph the given parabola, we find some points on it.
Let 
So, the points are 
.
Mark these points on the graph and join them using a smooth curve.
The graph is shown below.
From the graph, we conclude that at the vertex , it is minimum.
Answer:
42°
Step-by-step explanation:
its 42° because its smaller than 48° and that's the only option smaller lol
The answer is 5.19615242271 but if you round it to the nearest dp its 5.2
