Arnold makes a chart to summarize what happens when light interacts with matter and is reflected. Which idea does Arnold need to correct? In specular reflection, reflected rays move in the same direction. In scattering, light strikes particles in the atmosphere. In diffuse reflection, reflected rays move in different directions. In scattering, long wavelengths are scattered the most.
Answer:
In diffuse reflection, reflected rays move in different directions.
Step-by-step explanation:
Reflection refers to the bouncing off of light from a surface. Reflection can be regular or diffuse.
Regular reflection occurs when light bounces off a well polished surface while diffuse reflection occurs when light bounces off a rough surface.
During diffuse reflection, light is reflected in different directions.
Answer:
In scattering, long wavelengths are scattered the most.

How does the formula for the sample mean differ from the formula for population mean? Multiple choice question. To calculate the sample mean, you divide by the sample number plus one. The formulas are functionally the same, but 'n' (the sample size) is used instead of 'N' (the population size). For sample mean, the sum of values is divided by the number of values minus one.
Answer:
The formulas are functionally the same, but 'n' (the sample size) is used instead of 'N' (the population size).
Step-by-step explanation:
The sample mean is the average value for a set of observations which is derived from a population. While the population mean is the average value for the entire set of observation belonging to a particular study of interest.
The set of observation belonging to a population is denoted by 'N' ; while the sample size is denoted as 'n' :
The mean formula is written thus :
Population mean = Σx / N
Sample mean = Σx / n
Where, x = set of values.

50 Points:
What are the coordinates of the point that is
2/3 of the way from A to B?
Point A: -4,-1
Point B: 5,5
A. 1,2
B. 0,5/3
C. 2,3
D. -1,1
Answer:
(-2,3)
Step-by-step explanation:
For the point to be 2/3 of the way; it means it divides AB into the ratio 2 to 1
Now, we can use the internal section formula to get the coordinates of this point
(x,y) = (nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)
where (m,n) = (2,1)
(x1,y1) = (-4,-1)
(x2,y2) = (5,5)
(x,y) = (1(-4) + 2(-1)/(1+2), (1(-1)+2(5)/(1+2)
(x,y) = (-4-2)/3, (-1 + 10)/3
(x,y) = (-2,3)

sunayana borrowed a sum of Rs 25000 at 12 %p.a simple interest for 1 years 6 months and lent to bishwant at the same rate of compound interest compounded half-yearly for the same interval of time . How much profit did she make
Answer: Rs 275.40
Step-by-step explanation:
Since Sunayana borrowed a sum of Rs 25000 at 12 %p.a simple interest for 1 years 6 months, the total amount that she's expected to pay will be calculated thus:
First, well calculate the interest. This will be:
= PRT/100
= (25000 × 12 × 1.5 / 100)
= 4500
Total amount to be paid back will be:
= Rs 25000 + Rs 4500
= Rs 29500
Since she lent the money to Bishwant, the total amount that Bishwant will pay will be:
A = P(1 + r)^t
where,
A = Final Amount
P= Principal = 25000
r= Rate of interest =
t= Time = 3 cycles
Since it's compounded half yearly, then 1½ywars will be = 1½ × 2 = 3 cycles
The rate will be = 12%/2 = 6% yearly.
We'll then slot the values into the question and this will be:
A = P(1 + r)^t
A = 25000(1 + 0.06)³
A = 25000(1.06)³
A = 25000 × 1.191016
A = 29775.4
Therefore, Bishwant is expected to pay Rs 29775.4
Then the profit that Sunayana is expected to make will be:
= Rs 29775.4 - Rs 29500
= Rs 275.40

Find the height in centimeters of a square pyramid with a volume of 72cm^ 3 and a base edge length equal to the height
Answer:
The height of the pyramid is 6 cm.
Step-by-step explanation:
The volume of a square pyramid is given by:
[tex] V = \frac{1}{3}A_{b}h = 72 cm^{3} [/tex]
Where:
[tex]A_{b}[/tex]: is the area of the base
h: is the height
Since the base edge length is equal to the height, the area of the base is:
[tex]A_{b} = l^{2} = h^{2} [/tex]
Hence, the height is:
[tex] 72 cm^{3} = \frac{1}{3}A_{b}h = \frac{1}{3}h^{2}h [/tex]
[tex] h = (3*72 cm^{3})^{1/3} = 6 cm [/tex]
Therefore, the height of the pyramid is 6 cm.

using your graphing calculator what is the solution to this system?
Answer:
bro i think its 0.75 . -2.25
Step-by-step explanation:
Answer:
Fourth option
Step-by-step explanation:
If you dont have a graphing calculator, we can solve this system using elimination. If we subtract the two linesr functions, we get
[tex](3x - 8y = 29) - (3x + y = - 2) = - 9y = 31[/tex]
So our new equation is
[tex] - 9y = 31[/tex]
[tex]y = - \frac{31}{9} [/tex]
Now since we know what y is, we plug this in back into the equation and solve for x.
[tex]3x - 8( \frac{ - 31}{9} ) = 29[/tex]
[tex]3x + \frac{248}{9} = 29[/tex]
[tex]3x = \frac{13}{9} [/tex]
[tex]x = \frac{13}{27} [/tex]
The answer choice that resembles this mostly is the fourth option.

An isosceles triangle has an angle that measures 134°. Which other angles could be in that isosceles triangle? Choose all that apply. 23 20 72 81
Answer:
23
Step-by-step explanation:
one angle = 134
Other two angles are the base angles which are same.
x + x + 134 = 180 {Angle sum property}
2x + 134 = 180
2x = 180 - 134
2x = 46
x = 46/2
x = 23
Other two angles are 23 , 23
Cuánto dinero me gasto en colocarle baldosas a una sala comedor que tiene 9.30 de largo por 4.20 metros de ancho
La pregunta está incompleta ya que no se da el costo de la colocación de baldosas por m².
Suponga que el costo de los mosaicos por m² = c
Respuesta:
39.06c
Explicación paso a paso:
El costo del embaldosado será:
El costo por m² * área total a embaldosar
Dado que :
La dimensión de la habitación a embaldosar es:
Longitud = 9,30 metros
Ancho = 4.20 metros
El área total de la habitación a embaldosar es = Largo * ancho
Área total de la habitación a embaldosar = 9,30 m * 4,20 m
Superficie total de la habitación a embaldosar = 39,06 m²
Si el costo del mosaico por m² = c
El costo de embaldosar la habitación será:
39,06 * c = 39,06c

Explain how to plot the point (3, –7) on the coordinate plane.On a coordinate plane, point A is (negative 4, negative 1), point B is (negative 4, 1), point C is (5, negative 1), and point D is (5, 2). Point P is at (5, 1). Which point is a reflection of Point P across the x-axis?
Answer:
a) In a coordinate plane, the horizontal axis is the x-axis, and the vertical axis is the y-axis.
So, a point (x, y) is at:
A horizontal distance of x units from the origin.
A vertical distance of y units from the origin.
So the point (3, -7) is at:
3 units at the right from the origin
7 units downwards (because is a -7) from the origin.
The graph of the point can be seen below:
Now we want to find a reflection across the x-axis.
b) For a general point (x, y), a reflection across the x-axis gives:
(x, -y)
So, if our point P is:
P (5, 1)
The reflection across the x-axis just changes the sign of the y-value, which gives:
(5, -1)
Then the correct option is point C:
(5, -1)
Answer:
its C on exgenity

4. Name the first five terms of the arithmetic sequence. a1 = -35, d=4
Answer:
Step-by-step explanation:
We first have to write the equation for the sequence, then finding the first five terms will be easy. Follow the formatting:
[tex]a_n=a_1+d(n-1)[/tex] and we are given enough info to fill in:
[tex]a_n=-35+4(n-1)[/tex] and
[tex]a_n=-35+4n-4[/tex] and
[tex]a_n=-39+4n[/tex] or in linear format:
[tex]a_n=4n-39[/tex] where n is the position of the number in the sequence. We already know the first term is -35.
The second term:
[tex]a_2=4(2)-39[/tex] so
[tex]a_2=8-39[/tex] and
[tex]a_2=-31[/tex]
The third term:
[tex]a_3=4(3)-39[/tex] and
[tex]a_3=12-39[/tex] so
[tex]a_3=-27[/tex] and we could go on like this forever, but the nice thing about this is when we know the difference all we have to do is add it to each number to get to the next number.
That means that the fourth term will be -27 + 4 which is -23.
The fifth term then will be -23 + 4 which is -19. You can check yourself by filling in a 5 for n in the equation and solving:
[tex]a_5=4(5)-39[/tex] and
[tex]a_5=20-39[/tex] so
[tex]a_5=-19[/tex]
A computer company makes a rectangular screen with a diagonal of 20 inches. The width of the screen is 4 inches less than its length. The dimensions of the computer screen are modeled by the equation x2 + (x – 4)2 = 202. What is the value of x, the length of the screen? x = –16 x = –12 x = 12 x = 16
Answer:
Step-by-step explanation:
x = length of screen
x-4 = width of screen
x² + (x-4)² = 20²
x² + (x²-8x+16) = 400
2x² - 8x - 384 = 0
x² - 4x - 192 = 0
use the quadratic formula to solve for x
x = [4 ± √(4²-4·1(-192))]/[2·1]
= [4 ± √784]/2
= 4 ± 28]/2
= 16, -12
-12 is an extraneous solution, so x = 16 inches.
:::::
Exponents need to be marked with a ^. For example, (x-4)² can be written (x-4)^2.
Answer:
x = 16
Step-by-step explanation:
The answer above is correct.
In ΔABC, m < B = 22°, m < C = 52° and a = 30. Find the length of b to the nearest tenth.
Answer:
The length of [tex]b[/tex] is approximately 11.7.
Step-by-step explanation:
The sum of internal angles in triangles equals 180°, as we know the measures of angles B and C, we determine the measure of angle A by algebraic means:
[tex]A = 180^{\circ}-B-C[/tex] (1)
([tex]B = 22^{\circ}[/tex], [tex]C = 52^{\circ}[/tex])
[tex]A = 180^{\circ}-22^{\circ}-52^{\circ}[/tex]
[tex]A = 106^{\circ}[/tex]
The length of [tex]b[/tex] is found by the Law of Sine:
[tex]\frac{b}{\sin B} = \frac{a}{\sin A}[/tex]
[tex]b = a\cdot \left(\frac{\sin B}{\sin A} \right)[/tex]
([tex]a = 30[/tex], [tex]A = 106^{\circ}[/tex], [tex]B = 22^{\circ}[/tex])
[tex]b = 30\cdot \left(\frac{\sin 22^{\circ}}{\sin 106^{\circ}} \right)[/tex]
[tex]b \approx 11.7[/tex]
The length of [tex]b[/tex] is approximately 11.7.
