The enlarged size of the poster will be 13.5 inches.

A scale factor is defined as the ratio of the scale of a given original object to the scale of a new object that is its representation but of a different size (bigger or smaller).

The scale factor is defined as the proportion of the new image's size to that of the previous image.

Given that Alisha wants to enlarge a photograph to make into a poster for her room. The photograph is 6 inches tall. The poster will be created using a scale of 4.5 inches = 2 inches.

Scale factor = 4.5 / 2 = 2.25

The enlarged size of the poster will be calculated as:-

Size = 6 x 2.25

Number of Combinations

[tex]\displaystyle C(40,3)=\frac{40!}{3!(40-3)!}=\frac{40!}{3!\cdot37!}=\frac{40*39*38}{3*2*1}=40*13*19=9880[/tex]

To write 10 more than a number, we use the mathematical operation of addition and the notation 10 + Number = N+10.

To write 10 more than a number, we need to use the mathematical operation of addition. Addition is the process of combining two or more numbers to find the total or sum.

In this case, we are given the number 5 and we are asked to find the number that is 3 more than it. To do this, we can use the mathematical notation: 10 + Number = N+10.

This notation means that we are adding 10 to a number, which results in N+10. The "+" symbol is the addition operator and it is used to indicate that we are performing an addition operation. The "=" symbol is used to indicate that the result of the addition is N+10.

Another way to write 10 more than a number is to use the phrase "10 plus a number". This phrase indicates that we are adding 10 to a number to get N+10.

Therefore, In short, to write 10 more than a number, we use the mathematical operation of addition and the notation 10 + Number = N+10. This means that we are adding 10 to a number, resulting in N+10. It can also be written as "10 plus N", indicating the same operation.

A linear expression is in polynomials when it is expressed as the product of it's factor

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1. For example, x² is a variable raised to the second power, but x is a variable raised to the first power.

When two linear factors are expressed together the result forms a polynomial.

A polynomial is an expression in which the power of it's variable is higher than 1. quadratic expression is also an example of polynomial.

For example if an expression is given as (x+2)(x+3). The result of the expression will give x²+5x+6 which is a quadratic expression and a polynomial.

The sine function graphed is given as follows:

y = 0.5sin(x - π/4).

The sine function for this problem is defined as follows:

y = Asin(Bx - C).

For which the parameters are given as follows:

The difference between the highest value and the lowest value is of 1, hence the amplitude of the function is givne as follows:

2A = 1

A = 1/2

A = 0.5.

The period of the function is of 2π, hence the parameter b is obtained as follows:

2π/B = 2π

B = 1.

The sine function, without phase shift, should pass through the origin, while the function here was shifted right π/4 units, hence the parameter C is given as follows:

C = π/4.

Hence the function is:

y = 0.5sin(x - π/4).

There are several methods that can be used to solve a system of nonlinear equations, but three common ones are: substitution method, elimination method and graphing method.

Substitution method: This involves isolating one variable in one equation and substituting it into the other equation to eliminate that variable. You can then solve for the remaining variable and substitute it back into the original equation to find the solution.

Elimination method: This method involves adding or subtracting the equations in such a way as to eliminate one of the variables. Then you can solve for the remaining variable and substitute it back into the original equation to find the solution.

Graphical method: This method involves graphing both equations on the same coordinate plane and finding the point of intersection of the two lines. The coordinates of this point will be the solution to the system of equations.

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

Jake is buying baseball cards for his brother in college.

The price of a card is based on its condition.

The table shows the total cost of x number of cards for each condition.

He buys 6 that are in fair condition, 5 that are in good condition, and 2 that are in excellent condition.

The shipping cost for the baseball cards is $4.00.

The expression that represents the total cost of buying and shipping the baseball cards,

= 6(1.75) + 5(9.5) + 2(20.5) + 4

The solution is the set of values for the two variables (x, y) that satisfy both equations.

To solve a system of two equations with two variables that are both quadratic (2nd degree), you can use the following steps:

Write the two equations in standard form, which is ax² + bx + c = 0 for each equation, where a, b, and c are coefficients.

Solve each equation separately for one variable by factoring or by using the quadratic formula.

Substitute the value of one variable from one equation into the other equation, and solve for the other variable.

Substitute the value of the other variable from the previous step back into one of the original equations to find the value of the first variable.

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).

what is circumference ?

Circumference is the distance around the edge of a circle. It can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.

To express the speed of a point on the rim of the wheel in centimeters per second, we first need to find the circumference of the wheel using the diameter. The circumference can be found using the formula: C = 2πr, where C is the circumference and r is the radius of the wheel.

Since the diameter is 14cm, the radius of the wheel is 14/2 = 7cm.

Therefore, the circumference of the wheel is: C = 2π(7) = 14π cm

Next, we need to find the distance traveled by a point on the rim of the wheel in one revolution. This distance is equal to the circumference of the wheel.

So, the distance traveled by a point on the rim of the wheel in one revolution is: 14π cm

To find the speed in centimeters per second, we need to multiply the distance traveled in one revolution by the number of revolutions per minute.

The wheel rotate 2500 revolution per minute.

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).

Circumference is the distance around the edge of a circle. It can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.

We must first determine the circumference of the wheel using the diameter in order to describe the speed of a point on the rim of the wheel in centimeters per second. The formula C = 2r, where C is the circle and r is the radius of the wheel, can be used to determine the circumference.

Therefore, the circumference of the wheel is: C = 2π(7) = 14π cm

a₃x + b₃y + c₃z + d₃ = 0

Now first we need to check the value of Δ

If, Δ ≠ 0, then we can say that the system of equations is consistent and will give us a unique solution.

However, we are concerned with the case when Δ = 0.

If Δ = 0, then we need to find the values of Δ₁, Δ₂, and Δ₃.

If at least one of the three Δ₁, Δ₂, and Δ₃ is not equal to 0 then we say that the equation is consistent.

Now if,

Δ₁ = Δ₂ = Δ₃ = 0, then we need to do the following:-

We need to take any 2 equations and get the values of x and y in terms of z.

Now we need to substitute the value of x and y for these values in the third equation.

If the third equation is satisfied, we can say that they will have infinite solutions but if they don't, then we can say the given system of equations will have no solutions.
