Mathematics

Answer:

46

Step-by-step explanation:

The following discussion assumes that this figure is 2-dimensional, and that "boundary" here means "perimeter."

Assume that the left and right boundaries of the figure are half circles.  Then the "boundary" is the perimeter, that is, the distance completely around a circle of diameter 7; this is the circumference of the circle, and is 7π.  Next, multiply the shown 12 by 2, obtaining 24.

Then the perimeter  /  boundary of the figure is 7π + 24, or about 46.

Consider the set n of positive integers to be the universal set. sets​ h, t,​ e, and p are defined to the right. determine wheth
noname [10]

Answer:

The sets E' and P' are not disjoint.

Step-by-step explanation:

Definition: Two sets are disjoint if their intersection is an empty set.

The sets are defined as follows.

\text{Universal Set}, U=\{n|n \in \mathbb{Z}^+\},$ where  \mathbb{Z}^+$ is the set of positive integers.

H=\{n|n \in \mathbb{N}| n>100\}\\T=\{n|n \in \mathbb{N}| n

We are to determine if the sets E' and P' are disjoint.

E' and P' are the complements of E and P respectively.

Therefore:

E'=\{n|n \in \mathbb{N}| n$ is odd$\}\\P'=\{n|n \in \mathbb{N}| n$ is not prime\}

The intersection

E' \cap P' =\{n|n \in \mathbb{N}| n$ is odd but not prime$\}

Therefore, the sets E' and P' are not disjoint.

When x = -2 h (x) = |-2x-6|
stich3 [128]

Answer:

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

so you must first find what is the x and which one is the y in the function then you will find the answer when you solve the problem

What is the answer to -12 = 4(f-6)
mote1985 [20]

Answer:

Step-by-step explanation:

-12 = 4(-6 + f)

-12 = (-6 * 4 + f * 4)

-12 = (-24 + 4f)

-12 = -24 + 4f

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-4f' to each side of the equation.

-12 + -4f = -24 + 4f + -4f

Combine like terms: 4f + -4f = 0

-12 + -4f = -24 + 0

-12 + -4f = -24

Add '12' to each side of the equation.

-12 + 12 + -4f = -24 + 12

Combine like terms: -12 + 12 = 0

0 + -4f = -24 + 12

-4f = -24 + 12

Combine like terms: -24 + 12 = -12

-4f = -12

Divide each side by '-4'.

f = 3

Simplifying

f = 3

Hope helps you
