A 4 polygon is a two-dimensional shape with four sides and four angles.
What is polygon?Polygon is a closed figure in a plane made up of straight lines or curved lines that intersect in pairs. A polygon has at least three sides and angles. The sides can be of any length and the angles can be of any measure. Polygons are classified according to the number of sides they have, such as triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), etc. Polygons are used in many fields, from mathematics to engineering.
It is a type of quadrilateral, which is a polygon with four sides. Examples of 4 polygons include squares, rectangles, rhombuses, and trapezoids. All 4 polygons have four sides of equal length, and all their interior angles add up to 360 degrees.

The value of x when y = 1000 is 8.59.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
y = 1.7952 x [tex]2.0657^x[/tex]
Substitute y = 1000
1000 = 1.7952 x [tex]2.0657^x[/tex]
10³ = 1.7952 x [tex]2.0657^x[/tex]
Taking logs on both sides.
log 10³ = log (1.7952 x [tex]2.0657^x[/tex])
3 log 10 = log 1.7952 + x log 2.0657
3 x 1 = 0.25 + 0.32x
3 = 0.25 + 0.32x
0.32x = 3 - 0.25
x = 2.75/0.32
x = 8.59

2An asymptote is a line that a graph approaches but never touches. That line can be vertical, horizontal, or even slanted, and graphs can have multiple types of asymptotes.
3constant of variation (k) is a ratio that represents the relationship between the independent variable (x) and the dependent variable (y). It can be found by dividing y by x, if both of those variables have known values.
$9, 100 is invested in an account earning

Write a function showing the value of the

growth rate can be found from a constant
in the function. Round all coefficients in
the function to four decimal places. Also,
determine the percentage of growth per
year (APY), to the nearest hundredth of a
percent.
Answer: A = P(1 + r/n)^(nt)
Where
A is the future value of the account
P is the initial principal amount, which is $9,100
r is the annual interest rate, which is 3%
n is the number of times the interest is compounded per year, which is 4 (quarters)
t is the number of years
So the function for the value of the account after t years is:
A = 9100(1 + 0.03/4)^(4t)
To determine the percentage of growth per year (APY), we can use the formula:
APY = ( (A/P)^(1/t) - 1) * n
In this case,
APY = ( (A/9100)^(1/t) - 1) * 4
APY represents the annual percentage yield, which is the interest rate taking compounding into account.

Mike's car will be worth £4116 at the start of 2017 as the car decreases in value by 30% every year
How to evaluate for the decreased value of the carAt the start of 2014, Mike's car is worth £12000,
we shall calculate the decreased worth of the same car to the start of 2017 as follows:
At the end of 2014, 30% of £12000 is calculated as;
£12000 × 30/100 = £3600
At the start of 2015, the car will be worth
£12000 - £3600 = £8400
At the end of 2015, 30% of £8400 is calculated as;
£8400 × 30/100 = £25200
At the start of 2016, the car will be worth
£8400 - £2520 = £5880
At the end of 2016, 30% of £5880 is calculated as;
£5880 × 30/100 = £1764
At the start of 2017, the car will be worth
£5880 - £1764 = £4116
Therefore, Mike's car will decrease in value to worth £4116 at the start of 2017.

F(x) = x^2 - x - 1 Over which interval doe f have an average rate of change of zero
The interval over which f(x) = x² - x - 1 has an average rate of change of zero is (1/2, 1/2) as it is the only point at which the average rate of change is zero.
An average rate of change of zero means that the function is not increasing or decreasing over the interval in question. To find the interval over which f(x) has an average rate of change of zero, we need to find the critical points of the function. A critical point is a point at which the function's derivative is equal to zero or is undefined.
The derivative of f(x) = x² - x - 1 is:
f'(x) = 2x - 1
Setting f'(x) = 0, we get:
2x - 1 = 0
Solving for x, we get:
x = 1/2
Since this is the only critical point of the function, it is the point where the function has an average rate of change of zero. To determine the interval, we need to check the sign of the function's derivative on either side of the critical point.
f''(x) = 2 > 0
So x = 1/2 is the minima of the function
f'(x) = 2(1/2) - 1 = 0, at x = 1/2
so f'(x) > 0 for x < 1/2 and f'(x) < 0 for x > 1/2
Therefore the interval over which f(x) has an average rate of change of zero is (1/2, 1/2) or {1/2}.

If the marble has a volume of 18,000 cubic centimeters, what are the dimensions of the marble?
The dimensions of the marble is thus 10∛18 cm when the volume is 18000 cm³.
What is volume?An object's capacity is the amount of material it can hold inside, while an object's volume is the amount of space it takes up. Here, the cubic unit is used to measure either of the two.
Cubic units are used to measure volume. The quantity of cubes needed to completely fill any given figure, such as blocks in a box, is its volume.
As there is no definite shape is given we can assume that the shape is cube.
Volume of cube = a³
given the volume 18000cm³
dimensions of the marble,
a × a × a = 18000
a³ = 18000
a = ∛18000
a = 10∛18

(a) Find an equation of the parabola.
(b) Find the diameter of the opening CD, 11 cm from the vertex.
The equation and diameter CD of the parabola are x=1/10 y^2and 2√110
How to determine the standard equation of the parabola?In this question we have four case of parabolas with vertical axes of reference, whose standard formula is:
a(x – h)2 + k
Where:(h, k) - The vertex of the parabola.
a - Least distance between the vertex and the focus of the parabola.
Please notice that p < 0 when the directrix is above the focus, otherwise p < 0. The vertex is the midpoint of line segment between the directrix and the focus.
Given;
Vertex is at origins (0,0) and latus rectum = 10 and the graph open right so a is positive and the equation is:
x=a (y-k)^2+h.
To write the equation we need to find a using the latus rectum equation.
We substitute the values.Then inverse place of a with 10
Latus rectum=|1/a|
10=|1/a|
a=1/10
The equation:
x=a (y-k)^2+h
x=1/10(y-0)^2+0
x=1/10 y^2
-Assume the distance between C and the center is EC. If E is (11,0) and C is (11, y).
-EC=y
-The equation of the parabola is x=1/10 y^2
Now, Substitute the value of C coordinate, which
x=1/10 y^2
Substitute the value of C coordinate, which is (11, y).
11×10=1/(10×10) y^2
√(y^2 )=√110
y=EC=√110
Because the distance of EC = ED
CD=EC×2
CD=√110×2
CD=2√110
Therefore, the equation of parabola and CD will be x=1/10 y^2 and 2√110
