The minimum that Nolan would have to spend is $33.84  while the maximum he has to spend is $35.94

10 * 0.84 = 8.4

8 * 1.29 = 10.32

8 * 1.89 = 15.12

The minimum is  = 8.4 + 10.32 + 15.12

= 33.84 dollars.

10 * 1.89 = 18.9

8 * 1.29 = 10.32

8 * 0.84 = 6.72

The sum of the maximum is given as 18.9 + 10.32 + 6.72

= $35.94

Step-by-step explanation:

The total surface area of the cuboid is 143.52 cubic cm

The formula for calculating the surface area of a cuboid is expressed as:

SA = 2(lw + wh + lh)

where

l is the length = 7.2cm

w is the width = 3.1cm

h is the height = 4.8cm

Substitute

SA = 2(7.2*3.1 + 7.2*4.8 + 3.1*4.8)

SA = 2(22.32 + 34.56 + 14.88)

SA= 143.52 square cm

Hence the total surface area of the cuboid is 143.52 cubic cm

The transformation of a function may involve any change. The function f(x) is vertically stretched and shifted 5 units upwards to form h(x).

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Vertical shift

Stretching:

The function f(x)=x^(1/3) is transformed to form the function of  h(x)=(2x)^(1/3)+5. Therefore, the transformation made to the function is,

Vertically stretched by a factor of 2^(1/3) ⇒ 2^(1/3) × x^(1/3) = (2x)^(1/3)

Up by 5 units ⇒ (2x)^(1/3) + 5

Hence, the function f(x) is vertically stretched and shifted 5 units upwards to form h(x).

An equation is called any equality that contains one or more unknown quantities, which are called unknowns, and that are only generally verified for certain values of the unknowns.

Thus, for example: 4x - 2 = 3x + 1~4x−2=3x+1 is an equation because it is an equality in which there is one unknown, xx .

⇝Equation resolution:

[tex] \qquad \sf \dashrightarrow4x - 2 = 3x + 14x−2=3x+1

[tex] \qquad \sf \dashrightarrow4x - 2 = 3x + 14x−2=3x+1[/tex]

We transpose the term 3x to the first member.

3x to the first member.We will have:

[tex] \qquad \sf \dashrightarrow4x - 2 - 3x = 14x−2−3x=1[/tex]

Next we transpose the term -2 to the second member.

We will have:

[tex] \qquad \sf \dashrightarrow4x - 3x = 1 + 24x−3x=1+2[/tex]

[tex] \qquad \sf \dashrightarrow \: x = 3x = 3[/tex]

Let's check that x = 3x=3 satisfies the given equation:

Answer:

The value of x is 3

When x = 3 then both the LHS and RHS of the equation equal to the same number; 10.

Step-by-step explanation:

[tex]4x - 2 = 3x + 1 \\ 4x - 3x = 1 + 2 \\ x = 3 \\ [/tex]

When we substitute the value for x in the expression, we see that the expression represents the same number. i.e

Answer:

D. (f-g)(x) = |7x+1|-6

Step-by-step explanation:

f(x) = |7x + 1| - 8

The basic market graph is attached below.

A market is said to have reached equilibrium price when the supply of goods matches demand.

The equilibrium price is the only price where the plans of consumers and the plans of producers agree, where the amount consumers want to buy of the product, quantity demanded, is equal to the amount producers want to sell, quantity supplied. This common quantity is called the equilibrium quantity.

Quantity of gasoline:

Explanation of graph: The demand curve, D, and the supply curve, S, intersect at the equilibrium point E, with an equilibrium price of 1.4 dollars and an equilibrium quantity of 600.

The equilibrium is the only price where quantity demanded is equal to quantity supplied. At a price above equilibrium, like 1.8 dollars, quantity supplied exceeds the quantity demanded, so there is excess supply.

At a price below equilibrium, such as 1.2 dollars, quantity demanded exceeds quantity supplied, so there is excess demand.

Answer:

Step-by-step explanation:

Considering the definition of an equation and the way to solve it, a person will devote 28 years watching TV and 6 years sleeping.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.

The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true.

To solve an equation, keep in mind:

Being "x" the number of years watching TV, and knowing that:

the equation in this case is:

x + (x+22) =34

Solving:

x + x =34 -22

2x= 12

x= 12 ÷ 2

x=6

As the number of years sleeping will exceed the number of years watching TV by 22, then x +22= 6 +22= 28 years.

Finally, a person will devote 28 years watching TV and 6 years sleeping.

Por definición de perímetro y considerando el cambio de unidades, el perímetro de la caja en pulgadas es 12[(g+y)×2].

El perímetro de un figura geométrica plana se denomina a la longitud de su contorno. El perímetro es, por tanto, una medida de longitud.

En otras palabras, el perímetro de una figura de dos dimensiones es la distancia alrededor de la figura y es el resultado de la suma de los lados de una figura geométrica plana. Por lo que para el cálculo del perímetro es necesario conocer el número de lados de la figura y la longitud de cada uno de esos lados.

Una caja se puede considerar como una figura que tiene cuatro lados con dos medidas diferentes (alto y ancho).

El alto de la caja es "y" mientras que su ancho es "g" pies, por lo que su perímetro P es calculado como:

P= 2g + 2y= 2×(g+y) pies

Luego, se puede aplicar la siguiente regla de tres para realizar el cambio de unidades a pulgadas: si 1 pies equivale a 12 pulgadas, 2×(g+y) pies equivales a cuantas pulgadas?

[tex]P=\frac{2x(g+y) piesx12 pulgadas }{1 pie}[/tex]

The probability that the student will answer 5 correct questions is; P(5) = 0.053

The formula for binomial probability is;

P(X = x) = nCx * p^(x) * (1 - p)^(n - x)

Where;

p = probability of success.

n = number of trials, or the sample size.

x = the number of successes in the probability we are trying to calculate.

Now, we want to find P(5). We are given;

n = 12

x = 5

p = 1/5 = 0.2
