Answer:
I say C because it forms a trench and a trench is when one plate is pushed, or subducts, beneath another.I also did my research and it said " If a convergent boundary involves a continental landmass and an ocean basin, a subduction zone forms. Subduction occurs where a plate moves underneath the other."

the speed of light is approximately 3 x 10 to the 8th power meters per second, while the speed of sound is approximately 3.4 meters per second. How many times faster is the speed of light than the speed of sound?
Answer:
The speed of light is 8.8x10⁵ times faster than the speed of sound.
Step-by-step explanation:
We can find how many times faster (R) is the speed of light than the speed of sound as follows:
[tex] R = \frac{c}{v_{s}} [/tex]
Where:
c: is the speed of light = 3x10⁸ m/s
[tex]v_{s}[/tex]: is the speed of sound = 340 m/s (the value given in the statement, 3.4 m/s, is wrong)
[tex]R = \frac{3 \cdot 10^{8} m/s}{340 m/s} = 8.8 \cdot 10^{5}[/tex]
Hence, the speed of light is 8.8x10⁵ times faster than the speed of sound.
I hope it helps you!
What are the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right?
The coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
Case 1: If the point is in first quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 2: If the point is in second quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 3: If the point is in third quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 4: If the point is in fourth quadrant:Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Case 5: For points on axesYou can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.
Case 6: On originNo effect as we assumed rotation is being with respect to origin.
For this case, the point (-9,4) (present in second quadrant) is rotated by 90 degrees.
This rotation can be either clockwise, or counterclockwise.
Thus, for each case, we have:
case 1: Clockwise rotation:Then (x,y) → (y, -x), therefore, (-9,4) → (4, 9)
case 2: Counterclockwise rotation:Then (x,y) → (-y, x), therefore, (-9,4) → (-4, -9)
Now, when shifting to right by 4, that means, we're making no changes vertically, but old x-coordinates are increased by 4 to make them shift to right side as value of x increases as we go more and more to the right side with respect to the origin and in defaultly oriented cartesian space.
Thus, we have:
case 1: Clockwise rotation:
After translation of 4 units right:
(4, 9) → (4+4, 9) = (8,9)
case 2: Counterclockwise rotation:After translation of 4 units right:
(-4, -9) → (-4+4, -9) = (0,-9)
Thus, the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)

Select ALL expressions that are equivalent to -6. *
-7 + 13
-10 - (-4)
26 - 32
16 - 10
3 - ( - 3)
Answer:
The terms equivalent to - 6 are
- 10 - ( - 4)
26 - 32
Answer:
Only the 2nd and 3rd expressions are equal to -6
Step-by-step explanation:
The only way to do this is evaluating ot actually doing each expression:
Some key skills needed are subtraction with negative numbers, distributing the negative properly, and addition.
The first one is -7+13. This can be rewritten as 13-7. And this is 6, so it is not equal to -6. The 2nd one is -10-(-4). You have to distribute that minus sign after the -10 to the -4. Think of the subtraction symbol I mentioned as -1. -1(-4) is 4 since the negative signs cancel out. It would then be -10 + 4 which -6. So this works. This one is 26 - 32. You have to subtraction here. 26 - 32 is the opposite of 32 - 26. 32 - 26 is 6, so 26 - 32 would be -6. So the 3rd one is another one eqial to -6. This is simple subtraction. 16 - 10 is 6, so this one definitely does not work. This uses the same skill as number 2. Think of the minus sign after the positive 3 as a -1. -1(-3) is 3, so it would be 3 + 3 which is 6.Only the 2nd and 3rd ones work. Hope you understood and have a nice day!!

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)
Answer:
Part A: 0,6 1, 5.5 2,5.0 3,4.5 4,4.0 5,3.5 6,3.0

Part C: 0,6 1,5.7 2,5.4 3,5.1 4,4.8 5,4.5 6,4.2, this would still be a function, just at a slower rate of speed.

8 + 3x = 14
Answer:
x=2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Step-by-step explanation:
This is a linear equation, and we will need to get the variable by itself.
Let's calculate!
[tex]8+3x=14\\3x=14-8\\3x=6[/tex]
Now we divide both sides by 3. Dividing 3 by 3 is just 1, and we don't need to write the 1, and 6 divided by 3 is two! So your equation will look like this:
[tex]3/3x = 6/3\\x=2\\[/tex]
