Each picture shows how a mapping, f, maps elements of a domain onto a range.
deff fn [24]

Answer:

Top left

Step-by-step explanation:

If an x value (domain) leads to more than one y-value (range), it is not a function. In other words, if each input value leads to only one output value, it is a function. It's still a function if the y-value leads to multiple x-values.

A set W of strings of symbols is defined recursively by 1. a, b, and c belong to W. 2. If x belongs to W, so does a(x)c. Which o
Vadim26 [7]

Answer:

a. a(b)c  

b. a(a(b)c)c  

d. a(a(a(a)c)c)c          

Step-by-step explanation:

We are given the following in the question:

a,b,c \in W\\\text{If } x \in W \Rightarrow a(x)c \in W

a. a(b)c

It is given b belongs to W.

b \in W\\\Rightarrow a(b)c \in W

b. a(a(b)c)c

a(b)c \in W\\\Rightarrow a(a(b)c)c \in W

c. a(abc)c

a(abc)c does not belong to W because we cannot find x in W such that a(abc)c belongs to W.

d. a(a(a(a)c)c)c

a \in W\\\Rightarrow a(a)c \in W\\\Rightarrow a(a(a)c)c \in W\\\Rightarrow a(a(a(a)c)c)c

e. a(aacc)c

a(aacc)c does not belong to W because we cannot find x in W such that a(aacc)c belongs to W.

Would 1/5 be greater than 1/3 but less than 2/3
makvit [3.9K]
1/5 = 3/15
1/3 = 5/15
2/3 = 10/15
So no :)

Reason why:
You want to find the common denominator between all three fractions, so all fractions are the same proportions. So in this case, if you multiply 5*3 you get 15, making it the common denominator. Then since you multiplied the 5 in 1/5 by 3 to get 15, and you have to multiply the 3 in 1/3 and 2/3 by 5 to get 15, then you multiply the numerator by the same number.

Sorry I am terrible at explaining things. Hope this helped though!

What is the approximate area of a regular heptagon with a side length of 4 inches and a distance from the center to a vertex of
jok3333 [9.3K]
Split it into 7 triangles. Half-base of each is 2 so the distance of center to the midpoint of the base is (Pythagoras) square root of (4.62 - 22) = 4.162 triangle is this times 2, and with 7 triangles multiply also by 7 to get an approximate area of 58 sq in.
