The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

Step-by-step explanation:

Reflected over x = -3, new point : (1,4)

Reflected over y=x, new point = (4,1)

The values of x and y are 31 and 4 respectively

Given the expressions as;

2x-9y=26       (1)

6x-2y=-22      (2)

Make 'x' the subject from (1)

2x = 26 + 9y

x = 26 + 9y/ 2         (3)

Substitute value of x into (2)

6x-2y=-22

6 ( 26 + 9y/ 2) - 2y = -22

expand the bracket

156 + 54y/ 2 - 2y = -22

Find the LCM

156 + 54y - 4y  / 2 =-22

cross multiply

156 + 54y - 4y = -44

collect like terms

50y = -44 - 156

50y = 200

y = 4

Substitute y = 4 in (3)

x = 26 + 9y/ 2

x = 26 + 9(4)/ 2

x = 62/ 2

x = 31

Thus, the values of x and y are 31 and 4 respectively

Step-by-step explanation:

The minimum probability that an outcome falls between 42 and 98, according to Chebyshev's inequality, is at least 0.9184 (or 91.84% when expressed as a percentage).

Chebyshev's inequality states that for any probability distribution, the minimum proportion of values within k standard deviations of the mean is at least 1 - 1/k^2.

In this case, we are given that the mean (μ) of the distribution is 70 and the standard deviation (σ) is 8. We want to find the minimum probability that an outcome falls between 42 and 98, which corresponds to a range of 56 units.

To apply Chebyshev's inequality, we need to determine the value of k. Since we want to find the minimum probability, we want to maximize the range by setting k to its minimum value.

We can use the formula k = (x - μ) / σ, where x is the range we are interested in. Substituting the values, we have:

k = (98 - 70) / 8 = 3.5

Now we can use Chebyshev's inequality to find the minimum probability:

P(|X - μ| ≤ kσ) ≥ 1 - 1/k^2

P(42 ≤ X ≤ 98) ≥ 1 - 1/(3.5)^2

P(42 ≤ X ≤ 98) ≥ 1 - 1/12.25

P(42 ≤ X ≤ 98) ≥ 1 - 0.0816

P(42 ≤ X ≤ 98) ≥ 0.9184

Therefore, the minimum probability that an outcome falls between 42 and 98, according to Chebyshev's inequality, is at least 0.9184 (or 91.84% when expressed as a percentage).

Answer:

The answer is below

Step-by-step explanation:

The equation of the line passing through two points is given by:

\(y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\)

The equation of line AB is:

\(y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-1)=\frac{4-(-1)}{6-7}(x-7)\\\\y+1=-5(x-7)\\y+1=-5x+35\\y=-5x+34\)

The midpoint of two lines is given as:

\(x=\frac{x_1+x_2}{2}, y=\frac{y_1+y_2}{2}\\midpoint\ of\ AB \ is:\\x=\frac{7+6}{2}=6.5, y=\frac{-1+4}{2}=1.5\\ = (6.5,1.5)\)

The equation of line AC is:

\(y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-1)=\frac{5-(-1)}{5-7}(x-7)\\\\y+1=-3(x-7)\\y+1=-3x+21\\y=-3x+20\)

The midpoint of two lines is given as:

\(x=\frac{x_1+x_2}{2}, y=\frac{y_1+y_2}{2}\\midpoint\ of\ AB \ is:\\x=\frac{7+5}{2}=6, y=\frac{-1+5}{2}=2\\ = (6,2)\)

The product of the slope of a perpendicular bisector of a line and the slope of the line is -1. That is m1m2 = -1

The slope of the perpendicular bisector of AB is:

m(-5)=-1

m=1/5

The equation of the perpendicular bisector of AB passing through (6.5,1.5) is:

\(y-y_1=m(x-x_1)\\y-1.5=\frac{1}{5}(x-6.5)\\y=\frac{1}{5} x-8.25\)

The slope of the perpendicular bisector of AB is:

m(-3)=-1

m=1/3

The equation of the perpendicular bisector of AB passing through (6,2) is:

\(y-y_1=m(x-x_1)\\y-2=\frac{1}{3}(x-7)\\y=\frac{1}{3} x-4.33\)

2) The point of intersection is gotten by solving y = 1/5 x -8.25 and y = 1/3 x-4.33 simultaneously.

Subtracting the two equations from each other gives:

0= -0.133x - 3.92

-0.133x = 3.92

x = -29.5

Put x = -29.5 in y = 1/5 x -8.25 i.e:

y = -14.16

The point of intersection is (-29.5, -14.16)

A polygon with n sides is simply referred to as an n-gon.

A polygon with n sides is simply referred to as an n-gon. This naming convention allows for any polygon to be easily identified based on the number of sides it has, without the need for a specific name for every possible number of sides.

For example, a polygon with 3 sides is called a triangle, a polygon with 4 sides is called a quadrilateral, while a polygon with 5 sides is called a pentagon. However, for polygons with sides greater than 12, the names become less commonly used, and n-gon is often used instead as a general term to describe any polygon with n number of sides.

A polygon with a number of sides, n, that does not have a special name is typically referred to as an "n-gon".

A polygon is a geometric object with two dimensions and a finite number of sides. A polygon's sides are made up of segments of straight lines that are joined end to end. As a result, a polygon's line segments are referred to as its sides or edges. Vertex or corners refer to the intersection of two line segments, where an angle is created. Having three sides makes a triangle a polygon. A circle is a plane figure as well, but it isn't regarded as a polygon because it's curved and lacks sides and angles. So, while all polygons are two-dimensional shapes, not all two-dimensional figures are polygons.

For example, a polygon with 5 sides would be called a pentagon, but a polygon with 7 sides would simply be called a heptagon or a 7-gon.

Answer:

q = infinite amount of solutions

Step-by-step explanation:

Step 1: Write equation

8q + 12 = 4(3 + 2q)

Step 2: Solve for q

--------------------------------------------------------------

We see here that you can plug in any number q and it would render the equation true. You can also look at it as 2 linear lines that are same, and the same line has infinite amount of solutions.

Step 3: Check

Plug in q to verify it's a solution.

8(0) + 12 = 4(3 + 2(0))

0 + 12 = 4(3 + 0)

12 = 4(3)

12 = 12

8(1) + 12 = 4(3 + 2(1))

8 + 12 = 4(3 + 2)

20 = 4(5)

20 = 20

We also see in the check step that any value q works.

The solution to the equation 8q + 12 = 4(3 + 2q) is Q can be any real number.

We have,

To solve for Q in the equation 8q + 12 = 4(3 + 2q), we can follow these steps:

Step 1: Distribute the 4 to the terms inside the parentheses:

8q + 12 = 4 * 3 + 4 * 2q

Simplifying further:

8q + 12 = 12 + 8q

Step 2: Combine like terms on both sides of the equation:

8q + 12 = 12 + 8q

Step 3: Subtract 8q from both sides of the equation to isolate the q term:

8q - 8q + 12 = 12 + 8q - 8q

Simplifying further:

12 = 12

Step 4: Since both sides of the equation are equal, the equation is true for all values of q.

This means the solution is all real numbers.

Therefore,

The solution to the equation 8q + 12 = 4(3 + 2q) is Q can be any real number.

This is an incredibly long time, equivalent to about 111,000,000 years!  even with the ability to compute, store, and check for collisions at a rate of 2,000,000 instances per second, finding a collision in SHA3-256 with a probability of at least 1/100,000 is practically impossible.

The probability of finding a collision in a hash function with n-bit output, such as SHA3-256, is roughly proportional to the square root of the number of possible hash values is \(2^{(n/2)\).

SHA3-256, n is 256, so the number of possible hash values is

\(2^{(256/2)} = 2^{128.\)

Let t be the number of seconds we need to run the computation. In one second, we can compute 2,000,000 instances of SHA3-256.

In t seconds, we can compute 2,000,000t instances of SHA3-256.

The number of pairs of hash values that we can generate from 2,000,000t instances is

(2,000,000t choose 2) = (2,000,000t) × (2,000,000t - 1)/2.

To have a probability of at least 1/100,000 of finding a collision, we need the number of pairs of hash values to be at least 100,000 times the number of possible hash values, which is:

(2,000,000t) × (2,000,000t - 1)/2 >= 100,000 × 2¹²⁸

Simplifying and solving for t, we get:

\(t > = \sqrt{((100,000 \times 2^{128})/(2,000,000)^2 - 1/2,000,000)} \approx 3.52 \times 10^{15} seconds\)

The probability at least 1/100,000 of finding a collision is 2.12 x \(10^{29\) seconds is approximately \(6.73 x 10^{21\) years

In cryptography, a collision occurs when two different inputs produce the same hash output.

The probability of finding a collision increases as the number of inputs increases, and this is what we want to calculate.
Assuming we can compute, store, and check for collisions 2,000,000 instances of SHA-3 (SHA3-256) in one second, we can compute the number of possible inputs that can be hashed in a given time frame.

If we assume a year contains 31,536,000 seconds, then in one year we can compute:
2,000,000 * 31,536,000 = 63,072,000,000,000
That is 63.07 trillion inputs hashed in one year.
Next, we need to calculate the probability of finding a collision among all these inputs.

To do this, we can use the birthday paradox formula, which states that the probability of finding a collision in a set of n items is approximately \(n^2\)/\(2^{(k+1)\).

Where k is the number of bits in the hash output.

For SHA3-256, k = 256.
So, the probability of finding a collision in our set of hashed inputs is:
63,072,000,00 / 2(256+1) = 0.01266
This is an extremely small probability, which means it would take a very long time to find a collision with a probability of at least 1/100,000.

In fact, we would need to compute and store billions of times more hashes than what we can currently achieve in a year.
Therefore, to answer your question, we can say that even with the ability to compute, store, and check for collisions 2,000,000 instances of SHA-3 (SHA3-256) in one second, it would take an impractical amount of time to find a collision with a probability of at least 1/100,000.

Differentiate the position vector r with respect to time t to find the velocity vector u.
Since r=8e', differentiate r with respect to t:
u = dr/dt = d(8e')/dt = 0 (because e' is a unit vector, its derivative is 0)

Differentiate the velocity vector u with respect to time t to find the acceleration vector up.
