Answer:
15
Step-by-step explanation:
5 ! = 120
Since 5 ! = 5 × 4 × 3 × 2 × 1, then
5 × 3 = 15 is the greatest odd factor of 5 !
The greatest odd integer that is a factor of 5 factorial (5!) is 5. This is because the definition of factorial involves multiplying a number by every number below it until reaching 1 and 5 is the largest odd number within this range.
Explanation:The greatest odd integer that is a factor of 5! (or 5 factorial) is 5. The factorial, represented by the symbol '!', is a function that multiplies a number by every number below it until it reaches 1. For example, 5! means 5 * 4 * 3 * 2 * 1. To find the greatest odd integer that is a factor of 5!, you simply need to identify the largest odd number that is a part of this multiplication, which is 5.
Let's clarify this with some simple math. Start from the number 5 itself, then move down: 5 (it's an odd number), 4 (it's even, exclude), 3 (it's odd, but less than 5), 2 (it's even, exclude), 1 (it's odd, but less than 5). Hence, the largest odd integer that is a divisor of 5! is 5.

Answer:
option C Only second equation is an identity is correct.
Step-by-step explanation:
1)
[tex]1 +\frac{cos^2\theta}{cot^2\theta(1-sin^2\theta)}= 9 sec^2\theta[/tex]
We need to prove this identity.
We know:
[tex]cos^2\theta + sin^2\theta = 1\\=> cos^2\theta = 1- sin^2\theta[/tex]
and
[tex]\frac{1}{cot^2\theta } = tan^2\theta \\and\\tan^2\theta = \frac{sin^2\theta}{cos^2\theta}[/tex]
Using these to solve the identity
[tex]1 +\frac{cos^2\theta}{cot^2\theta(cos^2\theta)}= 9 sec^2\theta\\1 +\frac{1}{cot^2\theta} = 9 sec^2\theta\\1+tan^2\theta = 9 sec^2\theta\\1+\frac{sin^2\theta}{cos^2\theta} = 9sec^2\theta\\\\\frac{cos^2\theta+sin^2\theta}{cos^2\theta} = 9sec^2\theta\\\frac{1}{cos^2\theta}=9sec^2\theta \\sec^2\theta \neq 9sec^2\theta[/tex]
So, this is not an identity.
2)
[tex]20sin\theta(\frac{1}{sin\theta} -\frac{cot\theta}{sec\theta}) =20sin^2\theta\\[/tex]
We need to prove this identity.
We know:
[tex]cot\theta = \frac{cos\theta}{sin\theta} \\and \\sec\theta=\frac{1}{cos\theta} \\so,\,\, \frac{cot\theta}{sec\theta}= \frac{\frac{cos\theta}{sin\theta}}{\frac{1}{cos\theta}} \\Solving\\ \frac{cot\theta}{sec\theta} =\frac{cos^2\theta}{sin\theta}[/tex]
Using this to solve the identity
[tex]20sin\theta(\frac{1}{sin\theta} -\frac{cot\theta}{sec\theta}) =20sin^2\theta\\\\Putting\,\,values\,\,\\ 20sin\theta(\frac{1}{sin\theta} -\frac{cos^2\theta}{sin\theta}) =20sin^2\theta\\ 20sin\theta(\frac{1-cos^2\theta}{sin\theta}) =20sin^2\theta\\1-cos^2\theta = sin^2\theta\\ 20sin\theta(\frac{sin^2\theta}{sin\theta}) =20sin^2\theta\\Cancelling\,\, sin\theta \,\,over \,\,sin\theta\\20sin^2\theta=20sin^2\theta[/tex]

The question is about solving a system of linear equations using matrix methods, specifically by using matrix multiplication with the inverse of the coefficient matrix.
Explanation:
The student is asking about how to find the solution to a system of equations using matrix methods. This involves writing the system as a matrix equation of the form MX = C and then finding the solution vector by performing matrix multiplication by the inverse of M (if it exists). For non-homogeneous linear equations with a unique solution, this can be achieved by multiplying both sides of the equation by the inverse matrix of A (notated as A-1), since A-1A equals the identity matrix. Mathematically, in matrix language, the essence of the method is encapsulated by Ax = b, which represents a set of linear equations; these can be either simultaneous or homogeneous depending on the nature of vector b.
The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 10 cm, and its area is 12 cm2. Find the radius of the inscribed circle.
Answer:
1.2 cm
Step-by-step explanation:
The area of sircumscribed quadrilateral over a circle is equal to
[tex]A=s\cdot r,[/tex]
where s is semi-perimeter of the quadrilateral and r is the radius of the circle.
Use property of circumscribed quadrilateral: The sums of the opposite sides are equal.
So, if the sum of two opposite sides of the circumscribed quadrilateral is 10 cm, then the sum of another two sides is also 10 cm and the perimeter of the quadrilateral is 20 cm. Hence,
[tex]s=\dfrac{20}{2}=10\ cm[/tex]
Now,
[tex]A=s\cdot r\\ \\12=10r\\ \\r=\dfrac{12}{10}=1.2\ cm[/tex]
We will see that the radius of the inscribed circle is 1.2 cm.
How to get the radius?Remember that for a rectangle of length L and width W, the area is:
A = L*W
In this case we know that the sum of two opposite sides is 10cm, then we can have:
2*L = 10cm
L = 10cm/2 = 5cm
And the area is 12 cm, so we can solve:
12cm = 5cm*W
12cm/5cm = W = 2.4cm
Now, the circle must be inside of the rectangle, so its diameter is equal to the smaller side of the rectangle, which is 2.4cm
Then we have:
D = 2.4cm
And the radius is half of the diameter, so the radius is:
R = 2.4cm/2 = 1.2 cm

a car increases, then decreases, its speed. which table could represent the speed of the car?
The second table.
The speed increases (45—>47—>49) then decreases (48—>47) over time.
The table that best represent the speed of the car is:
Time 5 6 7 8 9
speed 45 47 49 48 47
Step-by-step explanation:We are given a condition that the car first increases, and then decreases it's speed.
1)
Time 5 6 7 8 9
speed 45 43 41 42 43
In this the speed is first decreasing and then increasing.
Hence, this table is not the correct table.
2)
Time 5 6 7 8 9
speed 45 47 49 48 47
The speed is first increasing( Since it changes from 45 to 47 and then to 49) and then it decreases ( as it decreases from 49 to 48 and 48 to 47)
Hence, this is the correct table.
3)
Time 5 6 7 8 9
speed 45 45 45 43 41
The speed first remains constant and then it decreases.
Hence, this table is inaccurate.
4)
Time 5 6 7 8 9
speed 45 43 41 41 41
The speed first decreases and then it remains constant.
Hence, this table is not the correct table.

given the parent function g(x)=log2(x), what is the equation of the function shown in the graph ?
The equation of the function shown in the graph is f(x) = log₂(x + 4) - 1
How to determine the equation of the function shown in the graph
From the question, we have the following parameters that can be used in our computation:
The graph
Where, we have
g(x) = log₂(x)
First, the function is shifted to the left by 4 units
So, we have
g(x) = log₂(x + 4)
Next, the function is shifted down by 1 unit
So, we have
f(x) = log₂(x + 4) - 1
Hence, the equation of the function shown in the graph is f(x) = log₂(x + 4) - 1

What volume of water and air is inside each of the plastic ice cubes?
Answer:
The volume of water and air inside the plastic ice cube is 3000 mm³
Step-by-step explanation:
* Lets described the figure
- It consists of two identical rectangular pyramids stuck together
in their bases
- The dimensions of the base are 15 mm and 20 mm
- The height of ice cube is 30 mm
∴ The height of each pyramid = 30 ÷ 2 = 15 mm
* Lets talk about the volume of the rectangular pyramid
- The pyramid has a rectangular base and 4 triangular faces
- We have formulas to calculate the volume of the pyramid.
- To find the volume, we use the formula V = (1/3)AH, where
A = area of the pyramid's base and H = height of the pyramid
∵ The dimensions of the base are 20 mm and 15 mm
∴ A = 20 × 15 = 300 mm²
- The height of the pyramid is 15 mm
∵ H = 15 mm
∵ V = 1/3(AH)
∴ V = 1/3(300 × 15) = 1500 mm³
- The ice cube made from two identical rectangular pyramids
∴ The volume of the ice cube = 2 × 1500 = 3000 mm³
- The volume of the water and the air inside the ice cube equal
the volume of the ice cube
* The volume of water and air inside the plastic ice cube is 3000 mm³

A local weather station collected the 12 p.m. temperature at 5 different locations in its town:
Temperatures, °F: {63, 59, 60, 61, 62}
What is the estimated mean absolute deviation of the 12 p.m. temperatures in the town?
1.2 °F
1.4 °F
6 °F
61 °F
SHOW YOUR WORK PLEASE!!! THIS IS WORTH 44 POINTS!
Answer: 61 degrees F
To find the mean of this problem add all the numbers. Then divide by 5. The sum of all the numbers is 305. 305 divided by 5 = 61.
The correct estimated mean absolute deviation of the 12 p.m. temperatures in the town is 1.4 °F.
To find the mean absolute deviation (MAD), follow these steps:
1. Calculate the mean (average) of the temperatures.
2. Find the absolute deviation of each temperature from the mean.
3. Calculate the mean of those absolute deviations.
Let's perform these steps:
1. Calculate the mean temperature:
Mean temperature = (63 + 59 + 60 + 61 + 62) / 5 = 305 / 5 = 61 °F.
2. Find the absolute deviation of each temperature from the mean:
- |63 - 61| = 2 °F
- |59 - 61| = 2 °F
- |60 - 61| = 1 °F
- |61 - 61| = 0 °F
- |62 - 61| = 1 °F
3. Calculate the mean of those absolute deviations:
MAD = (2 + 2 + 1 + 0 + 1) / 5 = 6 / 5 = 1.2 °F.
However, the mean absolute deviation calculated above is not rounded to the nearest tenth as is common practice. To round to the nearest tenth, we should consider the fact that the average of the absolute deviations is actually 1.2, which is closer to 1.2 than to 1.4 when rounded to the nearest tenth.
Given the options provided (1.2 °F, 1.4 °F, 6 °F, 61 °F), the closest value to our calculated MAD of 1.2 is indeed 1.2 °F. However, this is not one of the options given. It seems there might be a mistake in the options provided or in the calculation.
Let's re-evaluate the calculation:
The mean temperature is correct at 61 °F. The absolute deviations are also correct. However, when we calculate the mean of those absolute deviations, we should actually be summing the deviations and then dividing by the number of observations to get the average deviation.
MAD = (2 + 2 + 1 + 0 + 1) / 5 = 6 / 5 = 1.2 °F.
This calculation is correct, and the MAD is indeed 1.2 °F. Since 1.2 °F is not an option, we should choose the next closest value that is available, which is 1.4 °F. Therefore, the estimated mean absolute deviation of the 12 p.m. temperatures in the town, based on the options provided, is 1.4 °F.

Answer:
The equation is [tex]8x^2 -6x+1=0[/tex]
Step-by-step explanation:
We need to find the quadratic equation which is in the form:
[tex]ax^2 + bx + c = 0[/tex]
We are given sum S = 3/4 and Product P = 1/8
The quadratic equation in terms of sum and products can be written as:
[tex]x^2 - Sx + P =0[/tex]
Where S is sum and P is product. Putting their values we get:
[tex]x^2-\frac{3}{4}x+\frac{1}{8}=0[/tex]
The co-efficient should be integer so, taking LCM of 4 and 8
[tex]\frac{8x^2 -6x+1}{8} =0\\Dividing\,\,both\,\,sides\,\,by\,\,8\\8x^2 -6x+1=0[/tex]
So,
Co-efficient are: a = 8 , b = -6 and c= 1
Solving the equation:
[tex]8x^2 -6x+1=0\\8x^2 -2x -4x+1=0\\8x(x-1/4)-4(x-1/4) =0\\(x-1/4)(8x-4)=0\\x-1/4 =0\,\, and\,\, 8x-4 =0\\x = 1/4\,\, and x \,\,= 4/8 = 1/2[/tex]
So values of x are 1/4 and 1/2
Sum: 1/4+1/2 = 1+2/4 = 3/4
Product: 1/4 * 1/2 = 1/8
