Find the H.C.F. of 567 and 255 using Euclid’s division lemma.
Step-by-step explanation:
To find the Highest Common Factor (H.C.F.) of 567 and 255 using Euclid's division lemma, we can follow these steps:
Step 1: Apply Euclid's division lemma:
Divide the larger number, 567, by the smaller number, 255, and find the remainder.
567 ÷ 255 = 2 remainder 57
Step 2: Apply Euclid's division lemma again:
Now, divide the previous divisor, 255, by the remainder, 57, and find the new remainder.
255 ÷ 57 = 4 remainder 27
Step 3: Repeat the process:
Next, divide the previous divisor, 57, by the remainder, 27, and find the new remainder.
57 ÷ 27 = 2 remainder 3
Step 4: Continue until we obtain a remainder of 0:
Now, divide the previous divisor, 27, by the remainder, 3, and find the new remainder.
27 ÷ 3 = 9 remainder 0
Since we have obtained a remainder of 0, the process ends here.
Step 5: The H.C.F. is the last non-zero remainder:
The H.C.F. of 567 and 255 is the last non-zero remainder obtained in the previous step, which is 3.
Therefore, the H.C.F. of 567 and 255 is 3.
Determine the equation of the parabola with focus

(2,5) and directrix
�

x=18.
The equation of the parabola with focus (2,5) and directrix x=18 is (x - 18)² + (y - 5)² = (y - (5 + (18 - 2) / 2))².
A parabola is a conic section, the intersection of a right circular conical surface and a plane parallel to a generating
straight line of that surface.
The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.
The directrix is a straight line perpendicular to the axis of symmetry and placed symmetrically with respect to the focus.
The axis of symmetry is the line through the focus and perpendicular to the directrix.
The vertex of a parabola is the point where its axis of symmetry intersects the curve. It is the point where the parabola changes direction or "opens
up" or "opens down.
The directrix is a fixed straight line used in the definition of a
parabola. It is placed such that it is perpendicular to the axis of symmetry and at a distance from the vertex equal to the
distance between the vertex and focus. It is the line that is equidistant to the focus and every point on the curve.Here's
the solution to the given problem:
The distance between the directrix and the focus is equal to p = 16 (since the directrix is x = 18, the parabola opens to the left, so the distance is measured horizontally)
The vertex is (h,k) = ((18+2)/2,5) = (10,5)
Then we can use the following formula: (x - h)² = 4p(y - k)
Substitute the vertex and the value of p. (x - 10)² = 64(y - 5)
Expand and simplify. (x - 10)² + (y - 5)² = 64(y - 5)
The equation of the parabola is (x - 10)² + (y - 5)² = 64(y - 5).

Suppose that X has a hypergeometric distribution with N = 100, n = 4, and K = 20. Determine the following: a. P(X = 1) b. P(X = 6) c. P(X = 4) d.
The probabilities for the hypergeometric distribution with the given parameters are:
a. P(X = 1) ≈ 0.000407
b. P(X = 6) = 0
c. P(X = 4) ≈ 0.098117
d. P(X = 0) ≈ 1.97e-05
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.
To determine the probabilities for the hypergeometric distribution with the given parameters, we can use the following formula:
P(X = k) = (choose(K, k) * choose(N-K, n-k)) / choose(N, n)
where "choose(a, b)" represents the binomial coefficient, calculated as a! / (b! * (a - b)!)
Let's calculate the probabilities:
a. P(X = 1):
P(X = 1) = (choose(20, 1) * choose(100-20, 4-1)) / choose(100, 4)
= (20 * 80) / 3921225
≈ 0.000407
b. P(X = 6):
P(X = 6) = (choose(20, 6) * choose(100-20, 4-6)) / choose(100, 4)
= (38760 * 0) / 3921225
= 0
c. P(X = 4):
P(X = 4) = (choose(20, 4) * choose(100-20, 4-4)) / choose(100, 4)
= (4845 * 80) / 3921225
≈ 0.098117
d. P(X = 0):
P(X = 0) = (choose(20, 0) * choose(100-20, 4-0)) / choose(100, 4)
= (1 * 77) / 3921225
≈ 1.97e-05
Therefore:
a. P(X = 1) ≈ 0.000407

the positive integers and form an arithmetic sequence while the integers and form a geometric sequence. if what is the smallest possible value of ?
To solve this problem, we need to use the formulas for arithmetic and geometric sequences. The smallest possible value of n is 1 or 3 .
For the arithmetic sequence, we have a common difference of d = 2 (since we are adding 2 to each term to get the next term). So we can write the nth term as an = a1 + (n-1)d, where a1 = 1 is the first term.
For the geometric sequence, we have a common ratio of r = 3 (since we are multiplying each term by 3 to get the next term). So we can write the nth term as gn = g1 * r^(n-1), where g1 = 3 is the first term.
We want to find the smallest value of n such that an = gn. So we set the two formulas equal to each other and solve for n:
a1 + (n-1)d = g1 * r^(n-1)
1 + (n-1)2 = 3^(n-1)
Simplifying the right-hand side, we get:
1 + 2n - 2 = 3^(n-1)
2n - 1 = 3^(n-1)
We can solve this equation by trial and error. For n = 1, the left-hand side is 1 and the right-hand side is 1, so n=1 is a solution. For n=2, the left-hand side is 3 and the right-hand side is 2, so n=2 is not a solution. For n=3, the left-hand side is 5 and the right-hand side is 5, so n=3 is a solution.
Therefore, the smallest possible value of n is 1 or 3. We can check that both of these values work:
a1 + (n-1)d = 1 + 0*2 = 1
g1 * r^(n-1) = 3 * 3^(0) = 3
and
a1 + (n-1)d = 1 + 2*2 = 5
g1 * r^(n-1) = 3 * 3^(2) = 27
So the answer is n = 1 or 3.

Verify each identity. sin²(θ + π/2 ) = -con²θ
To verify the identity sin²(θ + π/2) = -cos²θ, we'll use trigonometric identities and algebraic manipulations:
Starting with the left-hand side (LHS):
sin²(θ + π/2)
We'll apply the sum-to-product formula for sine:
sin(A + B) = sin(A)cos(B) + cos(A)sin(B)
sin(θ + π/2) = sin(θ)cos(π/2) + cos(θ)sin(π/2)
Since cos(π/2) = 0 and sin(π/2) = 1:
sin(θ + π/2) = sin(θ) * 0 + cos(θ) * 1
sin(θ + π/2) = cos(θ)
Now let's simplify the right-hand side (RHS):
-cos²θ
We'll use the identity cos²θ = 1 - sin²θ:
-cos²θ = - (1 - sin²θ)
Expanding the negative sign:
-cos²θ = -1 + sin²θ
Now, comparing the LHS and RHS, we have:
sin(θ + π/2) = cos(θ)
and
-cos²θ = -1 + sin²θ
Both expressions are equivalent, so the identity sin²(θ + π/2) = -cos²θ is verified.

YOU WILL NOT GET THE ANSWER RIGHT. Express your answer as decimal, rounded to the nearest thousandth (three decimal places) in mi/hr - no spaces EXAMPLE: 78.345mi/hr
The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.
To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.
However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.
