The function for the area is:
A = 0.5H² + 2H
And if the height is 6ft, then the area is 30ft²
How to write the area function?We know that the area of a triangle is the product between the base and the height over two.
Here the base is 4ft more than the height H, then:
A = B*H/2
A = (H + 4)*H/2
A = 0.5H² + 2H
If the height is 6ft, then the area is:
A = 0.5*(6ft)² + 2*6ft = 30ft²

In the given diagram O is the centre of the circle.If <QRS=105°,what is the value of <PQS? Find it.
Answer:
∠ PQS = 15°
Step-by-step explanation:
PQRS is a cyclic quadrilateral
• the opposite angles of a cyclic quadrilateral sum to 180° , then
∠ QPS + ∠ QRS = 180°
∠ QPS + 105° = 180° ( subtract 105° from both sides )
∠ QPS = 75°
the sum of the 3 angles in Δ PQS = 180° , that is
∠ PQS + ∠ PSQ + ∠ QPS = 180°
∠ PQS + 90° + 75° = 180°
∠ PQS + 165° = 180° ( subtract 165° from both sides )
∠ PQS = 15°

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Smart One smartphone plan cost $20 per month for talk and messaging and $10 per gigabyte of data used each month. A second smartphone plan cost $60 per month for talk and messaging and $5 per gigabyte of data used each month.
Let {C} represent the total cost in dollars and {D} represent the amount of data used in gigabytes. The system of equation can be used to represent this situation are -
C = 20 + 10d
C = 60 + 5d
For same cost -
20 + 10d = 60 + 5d
5d = 40
d = 8
The cost would be -
C = 20 + 10d
C = 20 + 10 x 8
C = 100
Therefore, 8 gigabytes would have to be used for the plans to cost the same. The cost will be $100.

What is the area of triangle XYZ?
The area of the triangle xyz is 33.941...
To calculate area of triangle, we need to take the base and height's measurement.
Formula- 1/2 x Base x Height
However, Area may also be calculated when we know the 3 sides of the triangle.
It is known as "Heron's Formula"
Simply use this 2 step process :
Step 1-
Calculate "S" (which is half of the triangle's perimeter)
S = (side1 + side2 + side3) / 2
Naming the sides as a b and c respectively.
4 inches = a
5 inches = b
7 inches = c
S = ( a + b + c ) / 2
S = ( 4 + 5 + 7 ) / 2
S = 16/2
S = 8
Step 2: Calculating the area of the triangle XYZ
Formula:
Area ( A ) = √S(S−a)(S−b)(S−c)
put the values and you will get the answer.
A = √8(8−4)(8−5)(8−7)
A = 33.941..

Answer:
14 square inches
Step-by-step explanation:
Area of triangle = (h.b)/2
The height and base aren't specified, and no pic is provided
So I'll assume that the height is 4 and base is 7 ( or the opposite)
Area = (4.7)/2
= 14 square inches
If the height is 5 and base 7 ( or the opposite)
Area = (5.7)/2
= 17.5 square inches
If the height is 4 and base is 5 ( or the opposite)
Area= (4.5)/2
= 10 square inches

→The less than symbol (<) is the opposite, it indicates that one value is smaller than another. For example, if we say "A < B," this means that the value of A is less than the value of B.
→The greater than or equal to symbol (≥) indicate that one value is larger than or equal to another. For example, if we say "A ≥ B," this means that the value of A is greater than or equal to the value of B.
→The less than or equal to symbol (≤) indicate that one value is smaller than or equal to another. For example, if we say "A ≤ B," this means that the value of A is less than or equal to the value of B.
These symbols are commonly used in mathematical expressions, equations, and inequalities.
To write "greater than B" in mathematical notation, you would use the greater than symbol (>) followed by the letter B. For example:

Find the nearest tenth?A, I looked online and came across this statistic.
OM is probably perpendicular to CD and EF is perpendicular to ON, and I'm assuming there's more information there.
The chords are similarly split in half by the diameters that intersect them at right angles, so CM = (1/2) CD = 28.
r2 = OM2 + CM2 = 202 + 282 = 1184 r = 474 b; FN is the leg of a right triangle with other leg ON=16 and hypotenuse OF=r because it is a radius; r2 = OM2 + CM2 = 202 + 282 = r = 474 b.
r2 - ON2 = 1184 - 162 = 1184 - 256 = 928 = FN2 = 928
C, By the perpendicular diameter bisecting a chord theorem, EF is twice as large as FN.

Function in math is defined as a rule that gives value of a dependent variable that corresponds to specified values of one or more independent variables.
Here we have given the function called g(x) has the expression -3x² + 18x + 2.
And here we need to find the vertex for the function that can be calculated as,
As we all know that vertex form of a parabola is written as,
=> y = a (x - h)² + k
Here we know that (h, k) is the vertex
Then the given expression is written as,
=> g(x) = -3x² + 18x + 2
When we can be written by completing the square as follows,
=> y = -3x² + 18x + 2
Here we have to take 3 as common term, then we get
=> -3(x² + 6x)+ 2
now, we have to expand the expression within the brackets, then we get,
=> -3(x² + 6x+ 9)+ 2 + 27

What are the rules of longitude and latitude?.
Latitude is always presented before longitude when giving a coordinate. Degrees, minutes, and seconds are used to divide latitude and longitude. While a degree is made up of 60 minutes, a minute is made up of 60 seconds.
Latitude lines run parallel with each other from east to west. The more north you travel, the higher the latitude values. Last but not least, latitude values vary from -90 to +90. However, longitude lines run from north to south. Latitudes are lines that are horizontal and indicate how far away from the equator a location is. East and west directions with reference to the Greenwich, England, meridian are shown using longitudes, which are vertical lines. Cartographers and geographers. The grid system that enables us to locate precise or absolute locations on the surface of the globe is made up of latitude and longitude meridian.

The average ticket price for the concert, expressed in dollars, is given by the equation P = (TP + PR)/(T + ).
The average ticket price, P, in dollars, of all tickets sold to the concert is represented by the equation P = (T + ηR)/(T + η) where T is the original ticket price, R is the price increase, η is the number of tickets sold on the day of the concert, and T + η is the total number of tickets sold to the concert.
In this scenario, before the concert, the theater sells T tickets at a price of P dollars each, and on the day of the concert, the theater increases the ticket price by R dollars and sells η tickets.
Therefore, the average ticket price for all the tickets sold is the sum of the original ticket price and the increased ticket price, divided by the total number of tickets sold.
P = (TP + η(P+R))/(T + η)
P = (TP + ηPR)/(T + η)

How do you use the zero factor property to solve a quadratic equation?.
By applying the Zero Product Property, which asserts that if the product of two numbers equals zero, then at least one of the quantities must also equal zero, quadratic equations in factored form can be solved.
Any factored quadratic equation, such as (a + b)(a b) = 0, can be solved using the Zero Product Property. If a+b=0, then either an or b must also equal zero, according to the zero product property. We can solve problems like (x+2)(x-5)=0 thanks to this fundamental characteristic.
According to the zero product property, if the sum of two quantities is zero, then either one or both of the quantities must also be zero. This equation can be rewritten as (x + 3) (2 x 1) = 0 to help you solve it.
