What is the expression in mathematics?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations that can be evaluated to a specific value or result. Expressions can be simple or complex, and they can be used to represent mathematical relationships or to perform calculations.

Let c represent the number of ceramic pottery pieces in each box, and let p represent the number of handpainted plates in each box.

To find the total number of ceramic pottery pieces that Solana bought, we can use the following expression:

c* (50 + 58) = c*108

This expression shows that the total number of ceramic pottery pieces is equal to the number of ceramic pottery pieces in each box multiplied by the total number of boxes of ceramic pottery that Solana bought.

Alternatively, we can use the following expression:

c50 + c58 = 108*c

This expression shows that the total number of ceramic pottery pieces is equal to the product of the number of ceramic pottery pieces in each box and the number of boxes Solana bought on Monday plus the product of the number of ceramic pottery pieces in each box and the number of boxes Solana bought on Thursday.

Similarly, to find the total number of handpainted plates that Solana bought, we can use the following expression:

p* (40 + 46) = p*86

This expression shows that the total number of handpainted plates is equal to the number of handpainted plates in each box multiplied by the total number of boxes of handpainted plates that Solana bought.

Alternatively, we can use the following expression:

p40 + p46 = 86*p

This expression shows that the total number of handpainted plates is equal to the product of the number of handpainted plates in each box and the number of boxes Solana bought on Monday plus the product of the number of handpainted plates in each box and the number of boxes Solana bought on Thursday.

c) Diagonal plane - ellipse or parabola

What is a cone?

A cone is a three-dimensional geometric shape that narrows smoothly from a flat base (typically circular base) to a point called the apex or vertex (which creates an axis to the center of the base).

Cross section of a cone:

A cross section is a representation of a shape's axis of symmetry intersected by a plane. When a plane cuts a solid, such as a cone, cylinder, or sphere, it creates a shape known as a cross-section. Depending on how the plane cuts the cone, the cross-section of a solid, such as a cone, can be a circle, a parabola, or a triangle.

When a cone's cross-section is split horizontally, it is circular.

When a cone is cut vertically, its cross-section is an isosceles triangle, and this plane slices through the center of the cone.

When a cone is cut vertically, the cross-section is parabolic except for the plane running through the center.

One equation that represents the total value of the coins in cents is:

0.25x + 0.10y = 995

where x is the number of quarters and y is the number of dimes.

Another equation that represents the total number of coins is:

x + y = 47

These two equations make up a system of equations that can be used to find the number of quarters and dimes that add up to $9.95 and have a total of 47 coins.

Answer:

[tex]\begin{cases}x+y=47\\0.25x+0.1y=9.95\end{cases}[/tex]

Step-by-step explanation:

To solve this problem, we can create and solve a system of equations.

Define the variables:

Values of the coins:

Given there are a total of 47 coins:

[tex]x+y=47[/tex]

Given there is a total of $9.95 in quarters and dimes:

[tex]0.25x+0.1y=9.95[/tex]

Therefore, the system of equations that represents the problem is:

[tex]\begin{cases}x+y=47\\0.25x+0.1y=9.95\end{cases}[/tex]

To solve the system of equations, rewrite the first equation to isolate y:

[tex]y=47-x[/tex]

Substitute this into the second equation to eliminate y:

[tex]0.25x+0.1(47-x)=9.95[/tex]

Solve the equation for x to find the number of quarters:

[tex]\begin{aligned}0.25x+0.1(47-x)&=9.95\\0.25x+4.7-0.1x&=9.95\\0.15x+4.7&=9.95\\0.15x&=5.25\\x&=35\end{aligned}[/tex]

Therefore, there are 35 quarters.

Substitute the found value of x into the first equation and solve for y:

[tex]\begin{aligned}35+y&=47\\y&=12\end{aligned}[/tex]

Therefore, there are 12 dimes.

From the explicit rule the first three terms of sequence is 16, 16.5, 17.

       = 16.5

F(3) = 16 + (1/2) (3-1)

      = 16 + 1/2 x 2

Using Pascal's triangle we can find the binomial coefficient, by which we get 1m^4 + 16m^3 + 96m^2 + 128m + 256

Pascal's triangle is a triangular array of numbers in which each number is the sum of the two numbers directly above it. It is named after the French mathematician Blaise Pascal, who studied its properties in the 17th century. The rows of the triangle are numbered starting from 0, and the first number in row n is always 1. The other numbers in row n are the sum of the corresponding number in row n-1 and the number directly above it. The nth number in the kth row of Pascal's triangle is denoted by C(n,k) and it is called binomial coefficient, it is also denoted by nCk. It is used in many areas of mathematics, particularly in combinatorics and algebra, and it can be used to expand binomial expressions using the binomial theorem.

The binomial theorem states that for any non-negative integer n and any binomial expression (a+b)^n, the expansion is given by:

(a+b)^n = C(n,0)a^n*b^0 + C(n,1)a^(n-1)*b^1 + C(n,2)a^(n-2)b^2 + ... + C(n,n)a^0b^n

where C(n,k) = n!/(k!(n-k)!) is the binomial coefficient, which can be found using Pascal's triangle.

Using this theorem:

(m+4)^4 = C(4,0)m^44^0 + C(4,1)m^34^1 + C(4,2)m^24^2 + C(4,3)m^14^3 + C(4,4)m^0*4^4

Using Pascal's triangle we can find the binomial coefficient:

C(4,0)=1, C(4,1)=4, C(4,2)=6, C(4,3)=4, C(4,4)=1

So the expanded form of (m+4)^4 is:

1m^4 + 4m^34 + 6m^24^2 + 4m4^3 + 14^4
