Find the geometric mean of 24 and 45.
Answers
The geometric mean of 24 and 45 is equal to 32.86.
Given the following data:
Numbers = 24 and 45.What is geometric mean?Geometric mean is an average value that is used to indicate the central tendency of a data set containing a group of numbers, especially by determining the product of their values.
Mathematically, geometric mean is given by this formula:
[tex]G=\sqrt[n]{x_1x_2...x_n}[/tex]
Substituting the given parameters into the formula, we have;
[tex]G = \sqrt[2]{24 \times 45} \\\\G = \sqrt{1080}[/tex]
G = 32.86.

Line segmentsAB and XY are translated 2 units left and 3 units down to form line segments A'B' and X'Y'. Enter the distance, in units, between line segmentsA'B' and X'Y'.
Answers
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would show you how to answer it.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Translation is the movement of a point up, down, left or right. Translation is a rigid transformation, that is it preserves the shape and size of the figure. Types of rigid transformation are rotation, reflection, and translation.
If the distance between Line segment AB and line segment XY is 2 units and then both line segments are translated 2 units left and 3 units down to form line segments A'B' and X'Y'. The distance between the newly formed line segments A'B' and X'Y' would still be 2 units.

The value of a car decreases by 5% each year. Sophie bought a car two years ago for £10000. Work out the value now.
Answers
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]
[tex]y=10000\left(1-0.05\right)^2[/tex]
[tex]y=10000\left(0.95\right)^2[/tex]
On further simplification, we get
[tex]y=10000(0.95)(0.95)[/tex]
[tex]y=9025[/tex]
Therefore, the present value of the car is £9025.

Graph the image of the figure using the transformation given.

Answers
The original image undergoes reflection across x=-3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
In the given graph DEFG is the original image.
D'E'F'G' is the new image after the transformations applied.
A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.
Under reflection, the shape and size of an image is exactly the same as the original figure.
This type of transformation is called isometric transformation.
Hence, the original image undergoes reflection across x=-3.

$420 is divided between A, B and C. B receives $20 less than A, and C receives half as much as A and B together. how much does each receive?
Also could you explain the answer?
Answers
Answer:
A = $150
B = $130
C = $140
Step-by-step explanation:
Let the amount received by a be $x
b receives $20 less than a;
we have that;
b = x - 20
c receives half of Sum A and B
c = (x + x-20)/2
c = (2x-20)/2
c = x - 10
Add all and it gives 420
x - 10 + x -20 + x = 420
3x -30 = 420
3x = 420 + 30
3x = 450
x = 450/3
x =$150
a = 150
b = x - 20; 150 - 20 = 130
c = x-10
c = 150-10
c = $140
