Substitute each given value of the variable to find which, if any, is a solution of inequality.
OlgaM077 [116]

Given:

The inequalities are:

a) w

b) t>-25, t=-24, -25, -25.1, -27

To find:

The solution of inequalities by substituting the given values.

Solution:

a) We have,

w

After substituting the given values one by one, we get

-4.3 False statement.

-5.3 False statement.

-8.3 True statement.

-9 True statement.

Therefore the solutions of w are w=-8.3, -9.

b)

We have,

t>-25, t=-24, -25, -25.1, -27

After substituting the given values one by one, we get

-24>-25 True statement.

-25>-25 False statement.

-25.1>-25 False statement.

-27>-25 False statement.

Therefore, the solution of t>-25 is t=-24.

PLEASE HELP The volume of a cube is defined by the function, V(x), where the volume is measured in cubic meters. Find a polynomi
olya-2409 [2.1K]

we have

V(x)=x^3-12x^2+48x-64

we know that

The volume of a cube is equal to

V=b^{3}

where

b is the length side of a cube

Using a graph tool------> find the roots of the polynomial

see the attached figure

x=4

so

x^3-12x^2+48x-64=(x-4)^{3}

therefore

<u>The answer is</u>

the length side of a cube is equal to (x-4)

The board of an internet start up company has sixteen members. if one person is in charge of research and one is in charge of ma
Brilliant_brown [7]

The number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members is <u>240 ways</u>. Computed using permutations.

The permutation is the way of choosing a set of objects from a larger set of objects in a specific sequence.

If we are choosing r number of objects, from n number of objects in a specific sequence, then we follow permutation, and it is given as:

nPr = n!{(n - r)!}.

In the question, we are asked to find the number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members.

Since the position is to be chosen in a specific order, we will follow permutation.

The number of positions to be chosen (r) = 2.

The number of members (n) = 16.

Thus, the number of ways is given as:

nPr = n!{(n - r)!},

or, 16P2 = 16!{(16 - 2)!},

or, 16P2 = 16!/14! = 15*16 = 240.

Thus, the number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members is <u>240 ways</u>. Computed using permutations.
