each numbered angle is
1. right angle
2. obtuse angle
Road signs, often known as traffic signs, are posted along the side of roadways or above them to inform and direct drivers. Simple wooden or stone milestones were the oldest types of signs. Later, directional signs with arms were developed, such as the fingerposts used in the United Kingdom and their wooden equivalents in Saxony. Since the 1930s, as traffic volumes have increased, many nations have adopted pictorial signs or have similarly standardized and simplified their signs in an effort to overcome linguistic barriers and improve traffic safety. Such pictorial signals are typically based on international norms and use symbols (often silhouettes) in place of words. These signs were initially created in Europe and have since been adopted in varied degrees by the majority of nations.

Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
The measure of the central angle m∠VWU is 69 degrees
How to find central angles?Central angle is the angle formed by two arms and having the vertex at the centre of a circle.
The diameter of a circle runs from the centre of a circle.
The diameter SU and RT intersect each other at point Q.
Therefore,
m∠VWS = m∠TWU (Vertically opposite angles)
m∠VWU = m∠SWT (Vertically opposite angles)
Hence,
m∠TWU = 111 degrees.
Therefore,
m∠VWU = 360 - 111 - 111 /2
m∠VWU = 360 - 222 / 2
m∠VWU = 138 / 2
m∠VWU = 69 degrees
Therefore, the measure of the central angle m∠VWU is 69 degrees

The half life of the isotope dubnium-263 is 29 seconds. A sample of dubnium-263 was first measured to have 1024 atoms. After t seconds, there were only 32 atoms of the isotope remaining.
Write an equation in terms of t that models the situations
Question based on Khan Academy
The radiactive decay equation in terms of t that models the situation is 32 = 1024e^{(-0.0239/s)t}
What is radioactive decay?Radioactive decay is the spontaneous disintegration of atoms with the emission of radiation.
What is half life of a radioactive isotope?The half life of a radioactive isotope is the time it takes for half the number of atoms in a given sample to disintegrate.
How to Write an equation in terms of t that models the situations?To model the situation, we use the equation for radioactive decay which is given below
[tex]N = N_{0}e^{-{\lambda}t}[/tex] where
N = Number of atoms remaining after t seconds, N₀ = initial number of atoms, λ = decay constant = 0.693/T where T = half life of isotope and t = time of decayGiven that the half life of the isotope dubnium-263 is 29 seconds and sample of dubnium-263 was first measured to have 1024 atoms. Then, after t seconds, there were only 32 atoms of the isotope remaining. we have that
N = 1024 atoms, N₀ = 32 atoms, T = 29 sSo, λ = 0.693/29 s = 0.0239 /s
So, susbtituting the values of the variables into the equation, we have
[tex]N = N_{0}e^{-{\lambda}t}[/tex]
[tex]32 = 1024e^{-(0.0239/s)t}[/tex]
So, the radiactive decay equation in terms of t that models the situation is 32 = 1024e^{(-0.0239/s)t}

The sum of a geometric series with a first term of 3 and a common ratio of 10/9 is;
∑ [tex]3 (\frac{10}{9} )^k^-^1[/tex] where, K = 1 to n.
What is Geometric series?
A geometric series is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.
Given that;
The first term is 3 and the common ratio is 10/9.
Now, A geometric sequence has the form:
a, ar , ar², ar³, . . .
Hence, The nth term of a geometric sequence is;
⇒ ∑ [tex](ar^k^-^1)[/tex] where, k = 1 to n.
Therefore, the sum of geometric series with a first term of 3 and a common ratio of 10/9 is:
⇒ ∑ [tex]3 (\frac{10}{9} )^k^-^1[/tex] where, k = 1 to n.
So, The sum of a geometric series with a first term of 3 and a common ratio of 10/9 is;

After a 25%increase, the price is 300€.how many euros was the increase?
Step-by-step explanation:
the €300 as current price is 125% relative to the original price. in other words : 1.25 times the original price.
to get the amount of the increase we need to get the original price first and then subtract the original price from the current price.
to get the original price we need now to divide the actual price by 1.25 to undo the increase.
the original price
OP = 300/1.25 = €240
the price increase (of 25%) was then
300 - 240 = €60

Ox-3+√23
Ox-3± √51
Ox-3+√41
O x-3+√5
Answer:
x = 3 ± √23
Step-by-step explanation:
Simplify the quadratic equation.
[tex]3x^2-18x+5 = 473x^2-18x+5-47 = 0\\3x^2-18x-42 = 0\\\\a = 3\\b = -18\\c = -42\\\\x = (-(-18)\pm\sqrt{ (-18)^2-4(3)(-42) )} \div 2(3)\\x = (18\pm\sqrt{ 324+504)} \div 6\\x = (18\pm\sqrt{ 828}) \div 6[/tex]
Simplify further.
[tex]x = (18\pm\sqrt{ 23\times 36}) \div 6\\x = (18\pm6\sqrt{ 23}) \div 6\\x = 6(3\pm\sqrt{23}) \div 6[/tex]
Thus, the solution is
x = 3 ± √23
Hope this helps.
x = 3 + √23 and x = 3 - √23 are the two solutions of the given quadratic equation.
What is a Quadratic equation?ax²+bx+c=0, with a not equals to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
To solve for x in the equation 3x^2 - 18x + 5 = 47, we can begin by simplifying the equation:
[tex]3x^2 - 18x - 42 = 0[/tex]
Next, we can divide both sides of the equation by 3 to get:
[tex]x^2 - 6x - 14 = 0[/tex]
To solve for x, we can use the quadratic formula:
[tex]x =\frac{ (-b \pm \sqrt{(b^2 - 4ac))} }{ 2a}[/tex]
In this case, a = 1, b = -6, and c = -14, so we have:
[tex]x = \frac{(-(-6) \pm \sqrt{((-6)^2 - 4(1)(-14)))}}{2(1)} \\x = \frac{(6 \pm \sqrt{(36 + 56))}}{ 2} \\x = (6 \pm \sqrt{92}) / 2[/tex]
Simplifying the radical, we get:
x = (6 ± 2√23) / 2
Dividing both the numerator and denominator by 2, we get:
x = 3 ± √23
Therefore, the two solutions to the equation [tex]3x^2 - 18x + 5 = 47[/tex] are x = 3 + √23 and x = 3 - √23.
