The value of y is 58 and RS is 55.25 and ST is 17.5.

Equation is an expression that consists of variables, constants, and operators, and expresses a relationship between them. It is a mathematical statement that two expressions are equal. Equations can be used to solve a wide variety of problems in mathematics, science, engineering, and other fields. Examples of equations include the Pythagorean Theorem, the equation of a circle, and the equation of a line. Equations can be written in a variety of forms, such as symbolic, graphical, and numerical.

The value of y can be found by solving the equation 8y+4=58. By subtracting 4 from both sides, we get 8y=54.

Dividing both sides by 8, we get y=6.75.

Therefore, RS=8y+4=8(6.75)+4=55.25 and

ST=2y+4=2(6.75)+4=17.5.

Using equation, the number of large drinks is 126.

A drink stand is selling small drinks for $2 each and large drinks for $4 each. One day, a total of 150 drinks were sold for $552.

The number of large drinks sold can be calculated as follows:

Using equation,

let

x = number of small drinks

y = number of large drinks

Hence,

2x  + 4y = 552

x + y = 150

multiply equation(ii) by 2

2x  + 4y = 552

2x + 2y = 300

subtract equation(ii) from equation(i)

2y = 252

divide both sides by 2

y = 252 / 2

y = 126

Therefore,

number of large drinks = 126

The length of the triangle DEF f is 4.3 units.

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

The sine law can be used to find the side of a triangle. Therefore, let's find the side f of the triangle using sine law.

Therefore,

a / sine A = b / sin B = c / sin C

Hence,

e / sin E = f / sin F

E = 180 - 104 - 52

E = 24 degrees

Therefore,

1.8 / sin 24 = f / sin 104

cross multiply

1.8 sin 104 = f sin 24

divide both sides by sin 24

f = 1.8 sin 104  / sin24

f = 1.8 × 0.97029572627 / 0.40673664307

f = 1.7465323073 / 0.40673664307

The value of (fxg)(-3) if f(x)=5x-1 and g(x) =2x^2+1 will be 94.

A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Let A & B be any two non-empty sets; mapping from A to B will be a function only when every element in set A has one end, only one image in set B. It is a relation “f” in which each element of set “A” is mapped with only one element belonging to set “B”. Also in a function, there can’t be two pairs with the same first element.

f(x)=5x-1

g(x) =2x^2+1

A contour map/ plot is a way of representing a function with a two-dimensional input and a one-dimensional output.

Contours are obtained by intersecting the surface with the horizontal plane using the equation z = c. So the contour equation at height c is f(x,y) = c.

There are three types of contour lines displayed on the map:

Intermediate, Index, Supplement. The index line is the thickest contour line, and the points along the line are usually function numbered. Contours do not branch or split. Page 5 Steep slopes are represented by dense contour lines. Contour lines never intersect, but they can touch.

Omar needs to invest $9,788, to the nearest dollar, for the value of the account to reach $32,400 in 20 years

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

Given:

Omar is going to invest in an account paying an interest rate of 6% compounded monthly.

A =  $32,400 in 20 years

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for P

P = A / (1 + r/n[tex])^{nt}[/tex]

P = 32,400.00 / (1 + 0.06/12[tex])^{(12)(20)}[/tex]

P = 32,400.00 / (1 + 0.005[tex])^{240}[/tex]

P = $9,787.91

P = $9788  to the nearest dollar.

The volume of a cone is given by the formula V = (1/3) * π * r^2 * h Where the volume of this cone is approximately A:2016.

The volume of a cone is a measure of the amount of space inside the cone.

It is calculated using the formula: V = (1/3) * π * r^2 * h, where V is the volume, r is the radius of the base of the cone, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14).

The volume of the cone is the amount of space inside the cone, and is measured in cubic units (such as cubic centimeters, cubic meters, etc.).

From the diagram, we can see that the radius of the base of the cone is 4 and the height is 8. Plugging these values into the formula, we get:

V = (1/3) * π * 4^2 * 8

V = (1/3) * π * 16 * 8

No, V is not a vector space with the operations defined in this way. Because the operations defined in this question do not satisfy the properties required for V to be a vector space.

A vector space is a collection of objects (vectors) that can be added together and multiplied ("scaled") by numbers, called scalars. These operations must satisfy certain properties to be considered a vector space.

For example, one of the properties is the associativity of vector addition, which means that (u + v) + w = u + (v + w) for any vectors u, v, and w in V. However, with the given definition of +, we have (U + V) + W = (UV-1) + W = U(VW-1) which is not equal to U + (V + W) = U(VW-1)

Another property is the distributivity of scalar multiplication over vector addition, which means that c(u + v) = cu + cv for any scalar c and any vectors u and v in V. But with the given definition of ., we have C(U+V) = C(UV-1) which is not equal to C.U + C.V = CUV-1

Furthermore, with the definition given the additive identity and the existence of additive inverse are not guaranteed.

Therefore, V is not a vector space with the operations defined in this way.

Simplification is the process of making an expression or equation simpler and easier to understand or work with. In mathematics, simplification often involves combining like terms, removing unnecessary operations, or reducing the number of terms in an expression. The goal of simplification is to obtain an equivalent expression that is clearer, more manageable, and easier to interpret.

Here ,

is the step by step process:

(6x ^ 3 - x ^ 2 - 14x + 5):(2x - 1)

Step 1: Divide 6x^3 by 2x and write the quotient 3x^2.

Step 2: Multiply the denominator (2x - 1) by the quotient (3x^2)

Step 3: Subtract the result from the numerator and bring down the next term of the numerator ( x^2)

Step 4: Repeat the process by dividing the x^2 by 2x and write the quotient -x.

Step 5: Multiply the denominator (2x - 1) by the quotient (-x)

Step 6: Subtract the result from the numerator and bring down the next term of the numerator ( -14x)

Step 7: Repeat the process by dividing the -14x by 2x and write the quotient -7

Step 8: Multiply the denominator (2x - 1) by the quotient (-7)

Step 9: Subtract the result from the numerator and bring down the next term of the numerator (5)
