Answer:
555 m
Step-by-step explanation:
Because the model should have identical proportions to the real-life tower, the ratio between the height and shadow length of both diagrams should be the same.
Height (model) Height (real)
------------------------- = ------------------------
Shadow (model) Shadow (real)
Math:
0.9 meters x
-------------------- = ---------------------- <----- Ratio
0.2 meters 123.3 meters
4.5 = x / 123.3 meters <----- Divide 0.2 from 0.9
555 meters = x <----- Multiply both sides by 123.3

Can an exponential function be 1?
An exponential function can be equal to 1, but it would have to be a special case.
To determine this:
An exponential function has the form f(x) = ab^x, where a and b are constants. For the function to be equal to 1, the output value of the function must be 1 for all values of x. Therefore, we must have:
[tex]ab^x = 1[/tex]
In order for this equation to be true for all values of x, a and b must be chosen such that:
ab = 1
This means that a and b must be reciprocals of each other. For example, if a = 2, then b = 1/2. In this case, the function [tex]f(x) = 2(1/2)^x[/tex] would be equal to 1 for all values of x.
Another example would be if a = 1 and b = 1. In this case, the function [tex]f(x) = 1(1)^x[/tex] would be equal to 1 for all values of x.
It's important to note that while an exponential function can be equal to 1, it would only be in cases where a and b are reciprocals of each other and not with any other values.

What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The term-to-term rule for the sequence is to subtract 3 each time. If the 13th term is 25, we can use this rule to determine the 15th term.
We know that the 13th term is 25 and the rule is to subtract 3 each time, so:
13th term: 25
14th term: 25 - 3 = 22
15th term: 22 - 3 = 19

8.6 cm2 is the area of a triangle with a base of 4.8 cm and a height of 3.6 cm.
What are triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.
This characteristic is known as the triangle's angle sum property.
If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.
In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.
A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.
The vertex is the intersection of two straight lines. The triangle therefore has three vertices.

What is the solution to F(x)=g(x)
By using the given table we can find the two solutions of the equation:
f(x) = g(x)
are:
x = 1
x = 0.
What is the solution to the equation f(x) = g(x)?Here we have a table for the functions f(x) and g(x), and we want to solve the equation:
f(x) = g(x)
So we just need to find a value of x, such that both functions have the same output.
To check that, just look at the table and find a row (horizontal line) where the values of f(x) and g(x) are the same ones.
If you look when x = 0, we have:
f(x) = 1
g(x) = 1
So x = 0 is a solution.
And for the next row, when x = 1.
f(x) = 0.25
g(x) = 0.25

What is the solution to this system of linear equations XY 6 and Y x =- 10?
The solution to this system of linear equations y - x = 6 and y + x = -10 is (-8, -2).
y - x = 6
⇒y = x + 6
y + x = -10
⇒y = - x - 10
Since both equations are equal to y, equate them.
x + 6 = - x - 10
x + x = - 10 - 6
2x = - 16
Divide both sides by 2
x = -8
Put the value of x in either of the equations
y - x = 6
y - (-8) = 6
y + 8 = 6
y = 6 - 8

How do you solve exponential functions with different bases?
Sometimes we are given exponential equations with different bases on the terms. In order to solve exponential functions with different bases we must know logarithms and how to use them with exponentiation. We can access variables within an exponent in exponential equations with different bases by using logarithms and the power rule of logarithms to get rid of the base and have just the exponent.
What is exponential equationExponential equation is an equation whose power or base number (base) and power contains a variable.
An example of an exponential equation:
32^x-3 = 81^x+5 → the exponential equation with the power contains the variable x
(2x - 5)^x = (2x - 5)^3x-4 → the exponential equation with bases and powers contains the variable x
So, in the exponential equation, it can only be the exponent that contains the variable or it can also be the base and the exponent that contain the variable. This variable is denoted by a letter, it can be from a to z. But, in general, the variable symbol that is often used in questions is the letter x.
The solution to the exponential equation is the set of all x values that satisfy the exponential equation, or we can also call it a set of solutions. So, how to solve the exponential equation varies depending on the form of the equation. The two examples of equations above are two of several forms of existing exponential equations. This means that there are still other forms of exponential equations and each equation has its own way of solving it

Find the exact volume of the solid. Note that the figure is a half-sphere removed from the cylinder. 25mm 15mm
The exact volume of the solid is 963 2/3π cubic cm
How to determine the exact volume of the solid.From the question, we have the following parameters that can be used in our computation:
Shapes = Half-sphere and cylinder
A half-sphere is called a hemisphere, and the volume is calculated as
V₁ = (2/3)πr³
From the given figure (see attachment), we have
r = 14 cm/2
r = 7 cm
Substitute the known values in the above equation, so, we have the following representation
V₁ = (2/3)π * 7³
V₁ = 686/3π
Next, we have the volume of the cylinder to be
V₂ = πr²h
Where
r = 14 cm/2
r = 7 cm
And
h = 22 - 14/2 = 15
So, we have
V₂ = πr²h
Substitute the known values in the above equation, so, we have the following representation
V₂ = π * 7² * 15
V₂ = 735π
The volume of the solid is then calculated as
V = V₁ + V₂
So, we have
V = 686/3π + 735π
Evaluate the sum
V = 963 2/3π

A right triangle has a leg length of square root of 11 and a hypotenuse length of 9. Determine the length of the other leg of the right triangle.
The length of the other leg of the right triangle is √70. The result is obtained by using the concept of the Pythagoras theorem.
What is the Pythagoras theorem?
The Pythagoras theorem states that the square of the hypotenuse of a right triangle is equal to the squares of the other length sides. It can be expressed as
a² + b² = c²
Where
a = baseb = altitudec = hypotenuse (the longest side)Base altitude is also called as legs of the right triangle.
A right triangle has a leg length of √11 and hypotenuse of 9. Find the length of the other leg!
Let's say
a = √11c = 9The length of other leg is b, the shorter side of hypotenuse.
By using the Pythagoras theorem, we get b.
a² + b² = c²
(√11)² + b² = 9²
11 + b² = 81
b² = 81 - 11
b² = 70
b = √70
Hence, the length of the other leg of the right triangle is √70.

How do you find the coordinates of a triangle with midpoints?
To find the coordinates of a triangle with midpoints, you must first calculate the midpoints of each side by averaging the coordinates of the two endpoints.
To find the coordinates of a triangle with midpoints, you first need to calculate the midpoints of each side of the triangle. To do this, take the two endpoints of the side and average their coordinates. For example, if the two endpoints are (x1, y1) and (x2, y2), then the midpoint would be ((x1+x2)/2, (y1+y2)/2). Once you have all the midpoints, you can use the midpoint formula to calculate the coordinates of the triangle. The midpoint formula states that the coordinates of the triangle can be found by taking the average of the midpoints of the three sides.
