Answer:
No, to be a function a relation must fulfill two requirements: existence and unicity.
Step-by-step explanation:
- Existence is a condition that establish that every element of te domain set must be related with some element in the range. Example: if the domain of the function is formed by the elements (1,2,3), and the range is formed by the elements (10,11), the condition is not respected if the element "3" for example, is not linked with 10 or 11 (the two elements of the range set).
- Unicity is a condition that establish that each element of the domain of a relation must be related with <u>only one</u> element of the range. Following the previous example, if the element "1" of the domain can be linked to both the elements of the range (10,11), the relation is not a function.
Answer: 1,811 square foot
Step-by-step explanation:
Hi, to answer this question we have to solve the equation given, by substituting P = 4,148 and f=190 in the equation.
P = 1.85s + 4.2f
4,148 = 1.85s +4.2 (190)
Solving for s:
4,148 = 1.85s +798
4,148-798 =1.85s
3,350 = 1.85s
3,350/1.85 =s
s = 1,810.81 = 1,811 square foot (rounded)

Divide 5 by 1.25. That equals 4. Multiply 4 by 20 and that equals 80. So its 80 miles between Longwood and Milltown.
