The wavelength of red light is exactly the same as the wavelength of violet light, so it is not longer or shorter.
1. First, we need to identify the wavelengths of red light and violet light.
2. Red light has a wavelength of 8x10 to the -7 power meters and violet light has a wavelength of 8x10 to the -7 power meters.
3. Since both wavelengths are the same, the wavelength of red light is not longer or shorter than the wavelength of violet light.
The wavelength of light is measured in meters, and the wavelength of red light is 8x10 to the -7 power meters, while the wavelength of violet light is 8x10 to the -7 power meters. This means that both the wavelengths are exactly the same and the wavelength of red light is not longer or shorter than the wavelength of violet light. This is because the wavelength of light is a fundamental property that determines the color of light and the wavelength of red light and violet light are both the same.-

Given the grid on your work template, plot the points A(4,5) and B(-7,7). Calculate the distance between the 2 points, and find the midpoint.
distance=
u (rounded to hundredths place)
Answer:
distance = 11.1803 units
midpoint : (-1.5, 6).
Step-by-step explanation:
To plot the points A(4, 5) and B(-7, 7) on the grid, we locate the points at the coordinates (4, 5) and (-7, 7) respectively.
The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the values for A and B, we get:
d = √((-7 - 4)^2 + (7 - 5)^2)
d = √(11^2 + 2^2)
d = √(121 + 4)
d = √125
d = 11.1803 (rounded to hundredths place)
The midpoint of two points (x1, y1) and (x2, y2) can be calculated as follows:
x = (x1 + x2) / 2
y = (y1 + y2) / 2
The midpoint of A and B is:
x = (4 - 7) / 2 = -1.5
y = (5 + 7) / 2 = 6
So the midpoint of A and B is approximately (-1.5, 6).
charlie drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took hours. when charlie drove home, there was no traffic and the trip only took hours. if his average rate was miles per hour faster on the trip home, how far away does charlie live from the mountains?
If his average rate was miles per hour faster on the trip home, Charlie lives 480 miles from the mountain.
Let s = his speed to the mountains,
(s+20) = his return speed
The distance each way is the same,
Using the formula,
Distance = speed * time
12s = 8(s+20)
12s = 8s + 160
12s - 8s = 160
4s = 160
s = 160/4
s = 40 mph
So his speed to the mountain is 40mph
then,
Putting the values of speed and times we get,
40 * 12 = 480 miles to the mountains
Therefore, distance between charlie and the mountains is 480 miles.

Consider the function g(x)=−(x−1)^3−2. Which ordered pair lies on the inverse of the function?
(62,−3)
(−4, 123)
(3, 1)
(3,−6)
The ordered pair lie on the inverse of the function is (62,−3).
Option A is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = -(x - 1)³ - 2
The inverse of f(x).
y = -(x - 1)³ - 2
interchange x and y and solve for y.
x = -(y - 1)3 - 2
(y - 1)³ = -2 - x
(y - 1)³ = -(2 + x)
Cuberoot on both sides.
y - 1 = ∛-(2 + x)
y = ∛-(2 + x) + 1
Now,
Substitute in the inverse of g(x).
(62, -3) = (x, y)
(−4, 123) = (x, y)
(3, 1) = (x, y)
(3,−6) = (x, y)
So,
y = ∛-(2 + x) + 1
y = ∛-(2 + 62) + 1
∛-1 = -1
y = -1∛64 + 1
y = -1 x 4 + 1
y = -4 + 1
y = -3
So,
(62, -3) ______(1)
And,
y = ∛-(2 + x) + 1
y = ∛-(2 - 4) + 1
∛-1 = -1
y = ∛(-2 + 4) + 1
y = ∛2 + 1
y = 1.26 + 1
y = 2.26
So,
(-4, 2.26) _______(2)
And,
y = ∛-(2 + x) + 1
y = ∛-(2 + 3) + 1
∛-1 = -1
y = -1∛5 + 1
y = -1 x 1.71 + 1
y = -1.71 + 1
y = -0.71
So,
(3, -0.71) _______(3)
And,
y = ∛-(2 + x) + 1
y = ∛-(2 + 3) + 1
∛-1 = -1
y = -1∛5 + 1
y = -1 x 1.71 + 1
y = -1.71 + 1
y = -0.71
So,
(3, -0.71) ______(4)
Thus,
From (1), (2), (3), (4) we see that,
(62, -3) is the solution to the inverse of g(x).

c. What is the total perimeter of all the shaded triangles in Stage 3?
The total perimeter of all the shaded triangles in Stage 3 is 114 units.
What is midpoint theorem?The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side.
a) The shaded triangle in stage 1 is formed by the three midsegments of the triangle in stage 0 whose side is 16.
As the mid-segment theorem says the mid-segment is parallel and half in length to the third side of the triangle.
Apply the midsegment theorem, the side of the shaded triangle in stage 1 will be half of the side of the triangle in stage 0 i.e.,
16/2 =8
So, the perimeter is 3×8= 24 units
b) Perimeter = Perimeter of small triangle + Perimeter of 3 smaller triangles
= 24+3×3×4
= 60 units
c) Perimeter = Perimeter of small triangle + Perimeter of 3 smaller triangles + Perimeter of 9 smallest triangles
= 24+3×3×4+9×3×2
= 114 units
Therefore, the total perimeter of all the shaded triangles in Stage 3 is 114 units.

What is meant by right angled triangle?The term "right triangle" refers to a triangle with an interior angle of 90 degrees. The hypotenuse, the side that faces the right angle and is also the side with the longest side in a right triangle, and the height and base are the two arms of the right angle.
It is 90 degrees at a right angle. Angles smaller than 90 degrees are considered sharp angles. More over 90 degrees is considered an obtuse angle. Additionally, these angles aid in categorizing the various triangular varieties.
ΔABE = 180 degree
Let the equation be
∠A + ∠B + ∠E = 180 degree

A scuba diver is hired to take underwater photos. He begins swimming straight downward from an elevation of -5 meters relative to sea level. His elevation changes at a constant rate of 2.5 meters per minute. When he stops, his camera is still in a safe depth for use. For how many minutes could he have been swimming? Graph the solution set. Show your work.
Step-by-step explanation:
The scuba diver's elevation after t minutes can be represented by the equation y = -5 + 2.5t. The camera is in a safe depth for use when y is greater than or equal to 0, so we want to find the value of t when y is equal to 0.
Solving for t:
0 = -5 + 2.5t
5 = 2.5t
t = 5/2.5
t = 2
So the scuba diver could have been swimming for 2 minutes.
The graph of the solution set would be a line with slope 2.5 and y-intercept of -5, and the x-axis (y = 0) would be the line where the diver's depth is equal to sea level. The solution to the problem would be the point on the graph where y = 0 and x = 2.
if i'm given 3 points and found a vector projected onto another vector, how do i know those 3 points lie on the same line?
If you have three points in space , we can use direction vector , check if vectors are collinear or proportional to know those 3 points lie on the same line.
If you have three points in space and you find a vector that is projected onto another vector from each of these three points, it is possible to determine if the three points lie on the same line. Here's how you can do it:
Find the direction vector: Calculate the direction vector from one of the points to the other two points.
Check if the projection vectors are collinear: If the projection vectors from all three points are collinear, it means that they are all pointing in the same direction and are proportional to each other.
Check if the projection vectors are proportional: If the projection vectors are proportional, it means that they are all pointing in the same direction, and the three points are on the same line. Note that in order to determine if the projection vectors are proportional, you would need to know the magnitude of the projection vectors.
If the three points do lie on the same line, the direction vector found in step 1 will be proportional to the projection vectors found in step 2 and step 3, and all three points will lie on the same line in space.

Answer
He would need 54 ft² material to cover the one rectangular side of the tent with the rip and 213 ft² to recover the whole tent including the bottom. The volume of the tent is 189 ft³.
Part A
He would need 54 ft² material to cover the one rectangular side of the tent with the rip. As we have to find the area of a rectangular side of a rectangle we will use the formula Area= Length × Width
∴ Area of a Rectangle = length of the rectangle × width of the rectangle
A = 9 × 6
A = 54 ft²
Part B
David's dad would need 213 ft² material to recover the whole tent including the bottom. We know that the 2 sides of the tent are 54 ft² each. So, the total is 54 × 2 = 108 ft².
We will now find the area at the bottom of the tent
A = 7 × 9
A= 63 ft²
We will now find the area of the triangular sides
Triangle Area = 1÷2 × b×h
A = 1÷2 × 7 × 6
A = 1÷2 × 42
A = 21 ft²
As there are 2 triangular sides so we have to multiply it by 2
∴ 21 × 2 = 42 ft²
Add all the sides together 108 63 + 42 = 213 ft²
Part C
The volume of the tent is 189 ft³. It can be found by applying the formula V= b×h
Triangle area = 1÷2 × bh
A = 1÷2 ×7 × 6
A= 1÷2 × 42
A= 21
With a=21 as B and h= 9ft and applying the formula v=Bh

Suppose EL=24, DM = 12, and FM = 6.
Find the following lengths.
Note that the figure is not drawn to scale.
Answer:
DK = 18
MJ = 3
ML = 8
Step-by-step explanation:
In this problem, we need to use the Median of a Triangle Formula. This formula states that EM/EL = FM/JF = DM/DK = 2/3. To implement this into our question, we can write ML/EL = 1/3, so we get that ML = 24/3 = 8. We also know that MJ/FM = 1/2, so MJ = 6/2 = 3. Finally, DM/DK = 2/3, so DK = (12*3)/2 = 18.

If a battery has a radius of 4 millimeters and a height of 32 millimeters, approximately what is the area of the surface to be covered by the label? Use 3.14 for and round to the nearest hundredth.
The surface area to be covered by the label is 904.32 mm²
Assuming the shape of the battery is cylindrical.
The dimensions of the cylindrical battery:
radius r = 4 millimeters
