Answer:
A relation is a subset of cartesian product of two non empty sets whereas A function is a type of relation in which every element of first set has one and only image in the second set.
In a relation an element of the first set can have many images in the second set whereas in a function the first element can have only one image in the second set.
The given relation is not a function as the element 1 is related to 3 different elements in the second set.
Domain={1}
Range={7,14,21}
Answer:
66°59'57.4379"
Step-by-step explanation:
A suitable calculator can find the angle whose sine is 0.9205 and convert that angle to degrees, minutes, and seconds
θ = arcsin(0.9205) ≈ 66.999288° ≈ 66°59'57.4379"
___
Multiplying the fractional part of the degree measure by 60 minutes per degree gives the minutes measure:
0.999288° ≈ 59.95730'
And multiplying the fractional part of that by 60 seconds per minute gives the seconds measure:
0.95730' = 57.4379"
In total, we have 66°59'57.4379"

Answer:
Martin's Bowling cost = $5x
Isabelle Bowling cost = $5x + 3
where x is the total games Martin and Isabelle played.
Step-by-step explanation:
As given,
There are 2 people - Martin and Isabelle
Each game costs = $10
Let they both play total games = x
⇒total game cost = $10x
As they split the cost , it means the cost is divided into half
⇒Martin game cost = $5x
Isabelle game cost = $5x
Also, given that Isabelle pays $3 to rent shoes.
⇒$3 is added to the Isabelle game cost
∴ we get
Isabelle game cost = $5x + 3
so, we get
Martin's Bowling cost = $5x
Isabelle Bowling cost = $5x + 3
A for the first one and D for the second
