The conversion factor for converting centimetres to inches (in.) is 0.3937. Thus, the conversion of 167 centimetres to inches is equals to the 68.89 inches.
To convert from one unit to another, multiply by a conversion factor. The centimeter (cm) is the fractional part of the meter, the international standard unit of length, and is approximately equal to 39.37 inches. An inch is a unit of length or distance in measurement system of common American units and British Imperial units. One inch is defined as 1/12 of a feet. To convert a centimeter value to its equivalent inch value, simply multiply the centimeter value by 0.39370078740 (the conversion factor). The formula to convert centimeters to inches is: Inches
= Centimeters × 0.39370078740.
The factor 0.39370078740 is the result of dividing 1/2. So the best formula is inches = centimeters / 2.54. Now we need to convert 175 cm to inches. So, according to the formula, inches = 175 cm / 2.54
= 68.8976377953 ~ 68.89

please help me solve this paragraph proof for geometry, i’ll mark brainliest
Answer:
To prove that AD is a bisector of BC, we need to show that AD divides BC into two congruent segments.
Since AB ≅ AC, we have ∠BAC ≅ ∠CAB by the isosceles triangle theorem.
Since BD ≅ CD, we have ∠CBD ≅ ∠CDB by the same reasoning.
Now, we can use the angle bisector theorem, which states that if a ray bisects an angle of a triangle, it divides the opposite side into segments that are proportional to the adjacent sides.
Applying the angle bisector theorem to triangle BCD with angle ∠BCD, we get:
BD/DC = AB/AC
Since AB ≅ AC and BD ≅ CD, we can substitute and simplify to get:
BD/CD = 1
This implies that BD ≅ CD.
Therefore, AD divides BC into two congruent segments, and AD is a bisector of BC.
Hope this helps!
Suppose we want to compute x ≡ a^b (mod pq) for primes p and q, utilizing the Chinese Remainder Theorem and Fermat's Little Theorem. Select the true statements. The Chinese Remainder Theorem guarantees a unique solution to any system of modular equations. Fermat's Little Theorem allows us to conclude that ap^−1≡1(mod p) for any integer a and any prime p. By CRT,x=(a^b mod p) (q^−1 mod p) q + (ab mod p)(p^−1 mod q) p
By CRT,x=(a^b mod q)(q^−1 mod p) q + (a^b mod q)(p^−1 mod q) p
Ifb≥p, then a^b−p+1≡a^b (mod p)
If b ≡ c (mod p), then a^b≡a^c (mod p)
The true statements are: The Chinese Remainder Theorem guarantees a unique solution to any system of modular equations.
Fermat's Little Theorem allows us to conclude that ap^−1≡1(mod p) for any integer a and any prime p.
The first formula given in the question for computing x using CRT is also true.
Statement 3, "If b≥p, then a^b−p+1≡a^b (mod p)", is not necessarily true. Fermat's Little Theorem states that if p is prime and a is not divisible by p, then a^(p-1) ≡ 1 (mod p). However, this does not extend to arbitrary exponents b.
Statement 4, "If b ≡ c (mod p), then a^b≡a^c (mod p)" is true by Fermat's Little Theorem, which implies that a^(p-1) ≡ 1 (mod p), we can write b = kp + c for some integer k, then
a^b = a^(kp+c) = (a^p)^k * a^c ≡ a^c (mod p)
since a^p ≡ a^(p-1) * a ≡ 1 * a ≡ a (mod p) by Fermat's Little Theorem.

Answer:
Step 1: Given AD || BC and AB || CD.
Step 2: Angle A and Angle C are alternate interior angles, so they are congruent.
Step 3: Angle B and Angle D are alternate interior angles, so they are congruent.
Step 4: Angle B + Angle D = 180 degrees (because Angle A + Angle B + Angle C + Angle D = 360 degrees for a quadrilateral)
Step 5: Since Angle B and Angle D are congruent and their sum is 180 degrees, they must each be 90 degrees.
Step 6: Triangle ABZ and Triangle CDZ are both right triangles, since Angle B and Angle D are each 90 degrees.
Step 7: By the Angle-Angle Similarity Theorem, triangles ABZ and CDZ are similar.
Step 8: Since triangles ABZ and CDZ are similar, corresponding sides are proportional.
Step 9: Therefore, ZB/ZD = AB/CD, since ZB corresponds to AB and ZD corresponds to CD.
Step 10: Given that AB || CD, we know that AB/CD = AZ/CZ (the corresponding sides of similar triangles are proportional).
Step 11: Therefore, ZB/ZD = AB/CD = AZ/CZ.
Step 12: Since Angle A and Angle C are congruent (Step 2), we know that AZ = CZ (since they are opposite sides of an isosceles triangle).
Step 13: Therefore, ZB/ZD = AZ/CZ = 1, which means that ZB = ZD.
Thus, we have proved that ZB = ZD!

Problem of Tartaglia (1500-1577): among all positive numbers a, b whose sum is 8, find those for which the product of the two numbers and their difference is largest. (Enter your answers as a comma-separated list.)
a, b = _____
Let x = a - b and express abx in terms of x alone.
As per the information provided, a = 4√3/3 + 4, b = 4 - 4√3/3 the answer can be calculated with optimization method. it will be as follows:
Sum of a and b is 8, we get
a+b=8
b=8−a
Now, let x=a−b
Then we get,
[tex]x=a−(8−a) \\ x=2a−8 \\ x+8=2 \\ 1 \div 2x+4=a
[/tex]
we use this to answer to solve for b
[tex]b=8−a \\ =8−(1 \div 2x+4) \\ =4−1 \div 2x
[/tex]
Now we use the product of two numbers and its difference. This can be expressed as:
[tex]a⋅b⋅x=(1 \div 2x+4)(4−1 \div 2x) \\ x=2 {x}^{2} − \frac{1}{4} {x}^{3} +16x−2x^{2} \\ =−14x^{3} +16x

Thus, this expression that we need to maximize. Take the derivative, set it equal to zero, and solve for x
[tex]−3 \div 4x ^{2} +16=0 \\ 16 =3 \div 4 x ^{2} \\ 643=x \\ 28√3 \div 3=x[/tex]
Now for us to check that this is a maximum, we have to note that the second derivative is

the second derivative is −4√3. Since this number is negative, the point is a maximum.

Consider the following. x = sin(2t), y = -cos(2t), z = 4t; (0, 1, 2pi) Find the equation of the normal plane of the curve at the given point. Find the equation of the osculating plane of the curve at the given point.
The equation of the osculating plane is (-1/3)(x-0) + (1/3)(y+1) + (2/3)(z-8 π) = 0.
First, we find the point on the curve at
[tex]t = 2\pi[/tex]
[tex]x = sin(2(2\pi)) = 0 \\
y = -cos(2(2\pi)) = -1 \\
z = 4(2\pi) = 8\pi[/tex]
So the point on the curve is
[tex] (0, -1, 8\pi)[/tex]
To find the normal plane, we take the cross product of the partial derivatives:
[tex]r_t = (2cos(2t), 2sin(2t), 4) \\
r_t(2\pi) = (2cos(4\pi), 2sin(4\pi), 4) = (2, 0, 4) \\
r_tt = (-4sin(2t), 4cos(2t), 0) \\
r_tt(2\pi) = (0, -4, 0) \\
n = r_t × r_tt = (-16, -8, -8)[/tex]
So the equation of the normal plane is
[tex]-16(x-0) - 8(y+1) - 8(z-8\pi) = 0.[/tex]
To find the osculating plane, we first find the unit tangent and unit normal vectors:
[tex]T = r_t / ||r_t|| = ( \frac{1}{2})cos(2t)i + ( \frac{1}{2}) sin(2t)j + ( \frac{1}{4})k \\
N = n / ||n|| = ( \frac{2}{3})cos(2t)i + ( \frac{1}{3})sin(2t)j + ( \frac{1}{3})k[/tex]
Then the binormal vector is B = T × N, which is
[tex]( \frac{ - 1}{3})sin(2t)i + ( \frac{1}{3} )cos(2t)j + ( \frac{2}{3} )k[/tex]
Finally, the equation of the osculating plane is
[tex]( \frac{ - 1}{3})(x-0) + ( \frac{1}{3})(y+1) + ( \frac{2}{3})(z-8\pi) = 0[/tex]

The final inequality that represents how many blankets Elle can make in her workshop would be:
3x ≤ 52 and x ≥ 16
What is Inequality ?In mathematics, an inequality is a statement that compares two values or expressions using an inequality symbol such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).
An inequality indicates that one value or expression is smaller, greater, or not equal to the other value or expression.
The inequality "y <= 10" states that the value of "y" is less than or equal to 10.
Let "x" be the number of blankets Elle can make in her workshop.
Since each blanket requires 3 ft. of material, the total amount of fleece required for "x" blankets would be 3x ft.
We know that Elle has 52 ft. of fleece in her workshop, so we can set up the inequality:
3x ≤ 52
This inequality states that the amount of fleece required for "x" blankets must be less than or equal to the amount of fleece Elle has available.

What is angle?Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.
To determine the unknown angle measures of △DEF, we can use the fact that the sum of the angles of a triangle is 180°. Thus, if we know two angle measures in the triangle, we can use them to calculate the third.
Let's denote the two known angle measures as m∠D and m∠F. We can use the following equation to solve for the unknown angle measure:
m∠D + m∠F + m∠E = 180°
We can rearrange the equation to solve for m∠E:
m∠E = 180° - m∠D - m∠F
Therefore, once we know the measures of m∠D and m∠F, we can calculate the measure of m∠E.
For example, if m∠D = 40° and m∠F = 65°, then the measure of m∠E would be:
m∠E = 180° - 40° - 65° = 75°
