Answers
Wavelength is 0.00004 cm is the weather like for a violet light a large or small value and how do you know
The frequency of the violet light is [tex]7.495\times10^{14} s^{-1}[/tex].
Given that,
Wavelength λ=0.00004cm
First, we convert cm to nm
0.00004cm =400nm
These are connected by the equation in electromagnetic radiation (light):
c = λυ
where c refers to the speed of light value is 2.998 x [tex]10^{8}[/tex] m/s, λ refers to wavelength (m) and υ refers to frequency ([tex]s^{-1}[/tex]or Hz).
Now, c = λυ
2.998 x [tex]10^{8}[/tex] m/s=400[tex]\times[/tex][tex]10^{-9}[/tex]m[tex]\times\\[/tex]υ
υ=[tex]\frac{2.998\times10^{8} m/s}{400\times10^{-9}m }[/tex]
υ= [tex]7.495\times10^{14} s^{-1}[/tex]
Therefore, The frequency of the violet light is [tex]7.495\times10^{14} s^{-1}[/tex].

Each year, Jennifer's school hosts a student vs. teacher basketball tournament to raise money for charity. This year, there are eight teams participating in the tournament. During the first round, each team plays all of the other teams.
(c) Find a numerical method that you could use regardless of the number of the teams in the tournament to calculate the number of games in the first round.
Answers
A numerical method that you could use regardless of the number of the teams in the tournament to calculate the number of games in the first round is; (n − 1) + (n − 2) +…+ 1.
What is the Numerical Method used?
The first team will play with the other 7 teams.
Then the second team will play with the 6 other teams, as the game between the first and the second team has already been counted.
Similarly, the third team will play with 5 other teams, and so on. Thus, the
total number of games will be 7 + 6 + 5 + 4 + 3 + 2 + 1 = 28.
Therefore, in the first round there will be 28 games.
If there are 8 teams in the tournament, the number of games in the first round is (8 − 1) + (8 − 2) +…+ 1. Therefore, if there are n teams in the
tournament, the number of games in the first round is given by the sequence; (n − 1) + (n − 2) +…+ 1.

Division is one among the four basic operations of arithmetic, the ways in which numbers are combined to make new numbers. the opposite operations are addition, subtraction, and multiplication.
At an elementary level the division of two natural numbers is, among other possible interpretations, the method of calculating the number of times one number is contained within another.7 This number of times needn't be an integer. for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).
The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which is that the number of times the second number is completely contained in the first number, and a remainder, which is that the part of the first number that remains, when within the course of computing the quotient, no further full chunk of the dimensions of the second number can be allocated. for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.
For division to always yield one number instead of a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.

the water level of a lake fell by 11/2 inches during a 12/3-week long dry spell. Find the average rate at which the water level changed every week.
Answers
Every week, the water level dropped by 1.375 inches on average rate.
The average rate is what?
The ratio of "change in the function values" to "change in the interval endpoints" is referred to as the average rate of change of a function f(x) over an interval [a, b]. Specifically, [f(b) - f(a)] can be used to get the average rate of change (b - a). The average rate of change, represented by the symbol A(x), is, in other words, the "ratio of change in outputs to change in inputs." A(x) = (change in outputs), for example (change in inputs)
based on the available facts;
Detailed explanation:
A lake's water level dropped by -11/2 inches throughout the course of a 12-week dry period.
Total fall of water level = -11/2 inches = -5.5 inches
Time of fall = 12/3 week = 4 weeks
Average rate at which water level changed every week=Total fall of water level/Time of fall
=-5.5/4
=-1.375per inch every week
Average rate at which the water level changed every week = -1.375 inches

All pairs of congruent angles, and proportion that relates the corresponding sides for each pair of similar polygons are;

AC/ZX = BC/YX = AB/ZY
What are the congruent angles?
From the attached image, we see that Triangle ABC is similar to Triangle ZYX.
Now, the order of vertices in a similarity statement identifies the corresponding angles and sides. Since we know that ΔABC is similar to ΔZYX, we can take the corresponding angles of this statement and set them congruent to each other.
Now, since the corresponding sides of similar triangles are proportional to each other, we can write a proportion that relates the corresponding sides to each other as;
∠A ≅ ∠Z, ∠B ≅ ∠Y and ∠C ≅ ∠X

Answers
0.0001 is a very tiny possibility that you will get caught driving slower than the posted speed limit.
What is probability?Probability is a branch of mathematics that deals with the numerical representations of the likelihood that an event will occur or that a statement is true. A number between 0 and 1 is the probability of that an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
How can you calculate the probability?By simply dividing the actual favorable amount of possibilities by the entire number of possible outcomes, one can use the probability formula to determine the likelihood of an event.
According to the given data:Given,
radar speed detector is 0.56 mph.
inital speed = 33mph
final speed = 30mph
finding the probability that we clocked at below the speed limit.
so,
p(Z<(inital- final)/speed detector)
p(Z<(33-30)/0.56)
p(Z<5.35)
where Z = 1
p(1 - 0.9999)

Answers
Applying the definition of a midpoint of a segment, the lengths are:
RT = 74 units
RS = 37 units
What is the Midpoint of a Segment?The midpoint is defined as the point that bisects a line segment into two equal halves.
If M is the midpoint of RT, therefore:
RS = ST
RS = 6x + 7
ST = 9x - 8
Substitute
6x + 7 = 9x - 8
6x - 9x = -7 - 8
-3x = -15
x = -15/-3
x = 5
RT = RS + ST [segment addition postulate]
RT = 6x + 7 + 9x - 8 [substitution]
RT = 15x - 1
Plug in the value of x
RT = 15(5) - 1
RT = 74 units
RS = 6x + 7 = 6(5) + 7
RS = 37 units.
