It’s starting to get colder at night, so Sam decides to remove the goldfish from the pond in his backyard. He tries to catch the fish with a net; however, even though he can clearly see the fish in the water, he misses it. He infers that he missed because the light is being refracted. What is causing the refraction?
1: The air and the water are different colours.
2: The air and the water have different densities (and media).
3: The water is reflecting the light.
4: The air is reflecting the light.
EXPLAIN YOUR ANSWER
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. Which would make him see the fish in a spot that its not at. So 2 is the correct answer.

Which of the following is equivalent to 7-2(x+2)<-4-3(1 - x)?
Answer:
2 < x
Step-by-step explanation:
7-2(x+2)<-4-3(1 - x)
Distribute
7 - 2x-4 < -4 -3 +3x
Combine like terms
3 -2x < -7 +3x
Add 2x to each side
3-2x +2x< -7+3x+2x
3< -7+5x
Add 7 to each side

Between 1998 and 2018, inflation for prices of goods and services has been about 51%. Suppose a salon charged $18 for a basic haircut in 1998 and has been raising prices by a steady percentage each year to keep up with inflation.
Answer: $22.12
Step-by-step explanation:
I just did the compound interest formula which is
starting amount * (1. interst rate) ^ number of years
example if you have 100$ and you want to know how much it is worth if it appretiates by 7% of a period of 20 years it would look something like this;
100 * (1.10) ^20 = 672.74$
but since you have to figure out what it was in 2008 which was exactly half way in the period you divide the exponent by half so your formula should be;
I know the answer is right because I asked my teacher and it's correct.
REAL EXAMPLE: 18 * (1.51) ^.5 = 22.12$
The amount should be $22.12.

What is the following product? RootIndex 3 StartRoot 24 EndRoot times RootIndex 3 StartRoot 45 EndRoot RootIndex 3 StartRoot 69 EndRoot 4 (RootIndex 3 StartRoot 6 EndRoot) 6 (RootIndex 3 StartRoot 5 EndRoot) 6 (RootIndex 3 StartRoot 10 EndRoot)
Answer:
Answer is C
Step-by-step explanation:
The result of product [tex]\sqrt[3]{24} \times \sqrt[3]{45}[/tex] is [tex]6\sqrt[3]{5}[/tex].
The product is represented as:
[tex]\sqrt[3]{24} \times \sqrt[3]{45}[/tex]
Multiply the roots
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= \sqrt[3]{24\times 45}[/tex]
Rewrite the above expression as:
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= (24\times 45)^{1/3}[/tex]
Expand 24
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= (3 \times 8 \times 45)^{1/3}[/tex]
Express 8 as 2^3
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= (3 \times 2^3 \times 45)^{1/3}[/tex]
So, we have:
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 2(3 \times 45)^{1/3}[/tex]
Express 45 as 9 * 5
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 2(3 \times 9 \times 5)^{1/3}[/tex]
Express 9 as 3^2
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 2(3 \times 3^2 \times 5)^{1/3}[/tex]
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 2(3^3 \times 5)^{1/3}[/tex]
So, we have:
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 2\times 3(5)^{1/3}[/tex]
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 6(5)^{1/3}[/tex]
Rewrite as:
[tex]\sqrt[3]{24} \times \sqrt[3]{45}= 6\sqrt[3]{5}[/tex]
Hence, the result of product [tex]\sqrt[3]{24} \times \sqrt[3]{45}[/tex] is [tex]6\sqrt[3]{5}[/tex]

We gave a national verbal proficiency test that has a mean score of 500 with a standard deviation of 75. What raw score would correspond to the 60th percentile
Answer:
519
Step-by-step explanation:
Let's assume that the scores for the national verbal proficiency test follow a normal distribution.
Mean score (μ) = 500
Standard deviation (σ) = 75
According to a Z-score table, the score for the 60th percentile is roughly z = 0.253
For any score "x", the z-score is given by:
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
For z = 2.53:
[tex]0.253=\frac{X-500}{75}\\X=519[/tex]
The raw score to the 60th percentile is 519.

Answer:
106 degrees
Step-by-step explanation:
Since all the angles add up to 360 degrees we can find the value of x first and then substitute that value into angle VUX (12x+10)
11x + 1 + 12x + 10 + 75 + 90 = 360
23x + 176 = 360
23x = 184
x = 8
when x = 8,
<VUX = 12x + 10 = 12(8) + 10 = 106 degrees
Answer:
∠VUX = 106º
Step-by-step explanation:
Once the Quadrilateral add up to 360,
[tex]360\º=90\º+11x+1+75\º+12x+10\\360\º=176\º+23x\\8\º=x[/tex]
The measure of ∠VUX is [tex]12x+10[/tex]
Once [tex]x=8\º[/tex]
[tex]12(8)+10\\106[/tex]

The mystery number is a three-digit number. Its digits are 3, 6, and
2.
• The 6 has a digit on its left and on its right.
• The 2 is not the last digit.
What is the mystery number?
Answer:
263
Step-by-step explanation:
Let the number = xyz
The 6 has a digit on its left and on its right. It must be the middle number.
y = 6, so the number is x6z.
The 2 is not the last digit. It must be the first digit.
x = 2, so the number is 26z.
The remaining digit — 3 — must be the last digit.
z = 3, and the number is 263.
The mystery number is 263.

What number can be added to the right side of the equation to change it to a function with one real zero
Answer:
+3
Step-by-step explanation:
Where the graph crosses the x axis is where the real zeros exist. The parabola's minimum is at point (-3,-3) by adding a +3 to the right side of the equation will raise the minimum to point (-3,0) therefore giving it only one point where it touches the x axis. Then the parabola will only have one zero, the minimum of the parabola.

Use the information provided to write the equation of each circle.
Answer:
( x - 8 )^2 + ( y + 16 )^2 = 4; Option C
Step-by-step explanation:
~ We know that the standard circle equation ( x - a )^2 + ( y - b )^2 provided r ⇒ radius of the circle, centered at ( a, b ) ~
1. With that being being said, we are given the center with coordinates (8, -16), that can be plugged into this circle equation as a and b, while x and y are kept such: ( x - 8 )^2 + ( y - ( - 16 ) )^2 ⇒ simplified to be ⇒
( x - 8 )^2 + ( y + 16 )^2
2. Given the radius 2, it is convenient for us that we can simply substitute this value of r into the circle equation: ( x - 8 )^2 + ( y + 16 )^2 = 2^2
3. Now let us square the radius 2, as to simplify to ⇒
Answer: ( x - 8 )^2 + ( y + 16 )^2 = 4
