Answers
The general form of a quadratic equation is expressed as
ax^2 + bx + c
An example of a quadratic equation is
2x^2 - 4x - 2
The graph of this equation is shown below
The vertex of the graph is value of x and y at the bottom of the curve. Looking at the curve, the vertex is (1, - 4)
The axis of symmetry is the vertical line that divides the curve into two equal halves. The axis of symmetry of this curve is the line, x = 1
The y intercept is the point where the curve cuts through the y axis. From the graph, y intercept = - 2

If the height of a small box is 20cm, list two different Pairs of values which the company can use for the length and width of a small box?
Answers
The volume of the cereal box is 7200 cm³ and the surface area of the cereal box is 2776 cm².
The dimensions of the cereal box are given as:
Length = 25 cm
Width = 8 cm
Height = 36 cm
The volume of the cereal box is:
Volume = l × b × h
V = 25 cm × 8 cm × 36 cm
V = 7200 cm³
The surface area of the cereal box is:
Surface area = 2 l b + 2 b h + 2 h l
S = 2 (25) (8) + 2 (8) (36) + 2 (36) (25)
S = 400 + 576 + 1800
S = 2776 cm²
Therefore, we get that, the volume of the cereal box is 7200 cm³ and the surface area of the cereal box is 2776 cm².

The given exponential function is
[tex]Q=11e^{-0.13t}[/tex]The form of the exponential continuous function is
[tex]y=ae^{rt}[/tex]a is the initial amount (value y at t = 0)
r is the rate of growth/decay in decimal

The fish population of a receding pond is 8,000. The population is expected to decrease at a rate of 8% each year.Which function represents the population of the fish in the pond after x years?
Answers
Answer: f(x) = 8000(0.92)^x
Explanation:
The formula for calculating exponential decay is expressed as
f(x) = P(1 - r)^x
where
f(x) is the population after a period of x
P is the initial population
r is the decay rate
x is the time
From the information given,
P = 8000
r = 8% = 8/100 = 0.08
By substituting r = 0.08 into the equation. We have
f(x) = 8000(1 - 0.08)^x
f(x) = 8000(0.92)^x

In geometry, formal definitions are formed using other defined words or terms. There are, however, three words in geometry that are not formally defined. These words are point, line, and plane, and are referred to as the "three undefined terms of geometry".
a. Defined terms can be combined with each other and with undefined terms to define still more terms. An angle, for example, is a combination of two different rays or line segments that share a single endpoint. Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them.
b. Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the endpoint, and all points extending infinitely to one side of the endpoint.
