Answer:

-2 ; -1 ; 0 ; 1

Step-by-step explanation:

the inequality is satisfied in this interval [-2.5,1].

We are searching the integers: -2 ; -1 ; 0 ; 1

All the values of x that satisfy the inequality will be;

⇒ x = - 2, - 1, 0, 1

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is given.

Now,

The solution of the inequality are given as;

⇒ x ∈ [- 2.5, 1]

But we can find the integers which satisfy the inequality.

Hence, All the values of x that satisfy the inequality will be;

⇒ x = - 2, - 1, 0, 1

Thus, All the values of x that satisfy the inequality will be;

⇒ x = - 2, - 1, 0, 1

The side length of the smaller square is 3 cm.

Given that:-

Length of the larger square = [tex]3\sqrt{2}[/tex] cm.

We have to find the length of the smaller square.

As the length of the larger square is equal to the diameter of the circle

Hence,

Diameter of the circle = [tex]3\sqrt{2}[/tex] cm

Now,

The diameter of the circle is equal to the diagonal of the square.

Hence, diagonal of the square =  [tex]3\sqrt{2}[/tex] cm

Let the length of the square be x cm.

Hence, by pythagoras theorem, we can write,

[tex]x^2+x^2=(3\sqrt{2} )^2\\x^2+x^2=18\\2x^2=18\\x^2=9\\[/tex]

The factored form of the given algebraic expression by factoring out the Greatest Common Factor is 6y^2 (3y^2 + 4y + 1). Option A is correct.

We are given an algebraic expression:

18y^4 + 24y^3 + 6y^2

We need to factorize by factoring out the Greatest Common Factor.

In the given algebraic expression, we can see that;

6 is the Greatest Common Factor of 18, 24, and 6.

y^2 is the Greatest Common Factor of y^4, y^3 and y^2.

So, we will take the common 6y^2 from the given expression;

18y^4 + 24y^3 + 6y^2

= 6y^2 (3y^2 + 4y + 1)

So, option A is correct.

Thus, the factored form of the given algebraic expression by factoring out the Greatest Common Factor is 6y^2 (3y^2 + 4y + 1). Option A is correct.

Gregg manages a small cleaning business. He has 16 employees. The cleaners get  $13/hour. The cleaning supervisors get paid $18/hour. then Gregg employed 11 cleaners and 5 cleaning supervisors.

Set up a system of equations where c is the number of cleaners and s is the number of cleaning supervisors:

c + s = 16

13c + 18s = 233

Solve by substitution by solving for c in the first equation:

c + s = 16

c = 16 - s

Then, plug in 18 - s as c into the second equation:

13c + 18s = 233

13(16 - s) + 18s = 233

Solve for s:

208 - 13s + 18s = 233

208 + 5s = 233

5s = 25

s = 5

Then, plug in 5 as s into the first equation:

c + s = 16

c + 5 = 16

c = 11

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance.

A mathematical equation is a statement that two amounts or values are equal, such as 6 x 4 = 12 x 2. 2. A noun that counts. When two or more components must be taken into account collectively in order to comprehend or describe the overall situation, this is known as an equation.

Equations come in two varieties: identities and conditional equations. All possible values of the variables result in an identity. Only certain combinations of the variables' values make a conditional equation true. Two expressions joined by the equals symbol ("=") form an equation.

The motel revenue based on the number of rooms rented and group rental are as follows;

(a) The price for renting three rooms is $195

(b) The formula through which the unit rate of a room is found is aₙ = 71 - 3·(n -1)

(c) The function for the revenue, R(n) = 74·n - 3·n²

(d) The most amount that can be made is $456

The number of rooms that gives the most amount is 12 rooms

A revenue is the total amount received for the sale of goods and services

The number of rooms in the motel = 44

The price for renting one room = $71

The price for renting two rooms = $68

The per room group rate = $71 - $3 for each additional room
(a) The amount made if a family rents three rooms is given as follows;

The unit price for two rooms = $71 - $3 = $68

The unit price for three rooms = $68 - $3 = $65

The price for the three rooms is therefore;

$65 × 3 = $195

(b) The formula that gives the rate charged for each room to an organization is an arithmetic progression, which can be expressed as follows;

aₙ = a₁ + (n - 1)·d

Where;

n = The number of rooms the organization plans to rent

a₁ = The first term of the arithmetic progression = 71

d = The common difference = -3

Which gives;

aₙ = 71 - 3·(n - 1)

The price for each room when an organization rents n rooms is therefore;

aₙ = 71 - 3·(n - 1)

(c) The revenue for renting n room is given by the formula;

Revenue, R(n) = Unit rate × Number of rooms

∴ R(n) = (71 - 3·(n - 1)) × n = 74·n - 3·n²

(d) The -ve coefficient of n² in the formula with which the revenue can be found indicates that the function has a maximum value. The number of rooms that gives the most revenue is obtained at the from the derivative of the R(n) as follows;

R'(n) = 74 - 6·n = 0

n = 74/6 ≈ 12

Which gives;

[tex]R_{max}[/tex] = R(12) = 74 × 12 - 3 × 12² = 456

The rate of change of radius of the circle when the radius of the circle is 44 feet is 0.64 ft/s.

The area of the circle with radius R us given by,

A = πR²

It is given that the area is increasing at a constant rate of 178 square feet per second.

dA/dt = 178 ft²/s

Also, A = πR²

Differentiating A with respect to time,

dA/dt = 2πR.dR/dt

The rate of change of the radius is asked when the radius is 44 feet.

So, putting R = 44 ft.

dA/dt = 2π(44)dR/dt

178 = 2π(44)dR/dt

dR/dt = 0.64 ft/s

What is a standard deviation?

Data dispersion in regard to the mean is quantified by a standard deviation. Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

Here, we have

µ = 62 , σ = 5

P ( X < 66 )

By applying the standard deviation formula, we get

Z = ( X - µ ) / (σ/√(n)

Z = ( 66 - 62 ) / ( 5 / √50 )

Z = 5.6569

P (  ( X - µ ) / ( σ/√(n)) < ( 66 - 62 ) / ( 5 / √(50) )

P ( X < 66 ) =  P ( Z < 5.66 )

P ( X < 66 ) = 1

P ( X > 66 )  = 1 - P ( X < 66 )

By applying the standard deviation formula, we get

Z = ( X - µ ) / ( σ / √(n))

Z = ( 66 - 62 ) / ( 5 / √ ( 50 ) )

Z = 5.6569

P (  ( X - µ ) / ( σ / √ (n)) > ( 66 - 62 ) / ( 5 / √(50) )

P ( Z > 5.66 )

P ( X > 66 )  = 1 - P ( Z < 5.66 )

P ( X> 66 )  = 1 - 1

P ( X> 66 )  =  0

Hence, the probability of a sample of 50 cars recording an average speed of 66 mph or higher is 0.

Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).

The sides of the triangular base are:

b1 = 13 in.

b2 = 14 in.

b3 = 15 in.

The triangular base is a right triangle, and so the height is one of our sides. We will use

h = 12 in.

The length of the prism is

l = 20 in.

total surface area = bh + (b1+b2+b3)*l

bh = 12*20 = 240 [tex]cm^{2}[/tex]

l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840 [tex]cm^{2}[/tex]
