Which statement BEST expresses a connection between gravity and friction? A. Gravity and friction work together to provide the strong, opposing force that slows a snowboarder's ride. B. Gravity and friction are connected as they are the only two factors influencing speed when snowboarding. C. Gravity and friction are opposing forces; gravity holds a snowboarder in place while friction pulls a snowboarder down. D. Gravity and friction result in successful snowboarding after the transference of gravity into energy and a lubricating water layer produced by friction.

Write a rule to describe each transformation #9 & #11
Answer:
Step-by-step explanation:
Remark
I really don't know what to write to these questions. I can never tell what the problem is. Perhaps it is right at the very beginning. You have to recognize what is taking place. In problem 9, the easiest point to follow is H going to H'. Do you see what is happening? H is sitting on the x axis and then something happens to it and behold, it is now sitting on the y axis. So it has rotated 90 degrees but which way?
Take your finger or a pencil and put it on H. Then make a circular motion to get to H'. You are going clockwise. (keep going in that direction till you wind up where you started. You are going in the direction of one of those old fashioned clocks. Now the trick in a rotation is if you can figure out what one point is doing, you know what all points are doing on the given figure.
So the translation is 90 degrees clockwise. That means the following rule must be operating
(x,y) ===> (y, - x)
H(-3,0) ===> H'(0, - - 3) = H'(0,3)
I(-2,1) =====>I'(1, - - 2) = H'(1,2)
J(0,1) =====>J'(1,0)
G(-3,-3)====>G'(-3, --3) = G'(-3,3)
11
At first you may think that this is a translation of some kind. I thought so at first. D and D' certainly look that way and C and C' also look that way. But B and E are not well behaved. You are looking at a 180 degree rotation
The rule you need here is (x,y) becomes (-x , - y)
I'll leave C and D to you and do one of the B and E
E(3,5)=E'(-3 , - 5)

Answer:
9) (x, y) ⇒ (y, -x) . . . . rotation 90° CW
11) (x, y) ⇒ (-x, -y) . . . rotation 180°
Step-by-step explanation:
9) Distance from the origin to an image point is the same as to the preimage point, but the direction is changed by 90° in the CW direction. For example, J is north of the origin, but J' is east, a direction change of 90° CW.
The transformation describing a 90° CW rotation is the rule ...
(x, y) ⇒ (y, -x)
__
11) Distance and direction to each image point from the origin are equal and opposite of distance and direction to the preimage point. The figure has been rotated 180°. The corresponding rule is ...
(x, y) ⇒ (-x, -y)

how to solve y=-10x+3?
9514 1404 393
Answer:
top down: 13, 3, -7, -47
Step-by-step explanation:
You evaluate any equation by putting the numbers in place of the corresponding variables and following the rules of arithmetic.
For x = -1, put -1 where x is and do the math.
y = -10(-1) +3 = 10 +3 = 13
For x = 0, put 0 where x is and do the math.
y = -10(0) +3 = 0 +3 = 3
For x = 1, put 1 where x is and do the math.
y = -10(1) +3 = -10 +3 = -7
For x = 5, put 5 where x is and do the math.
y = -10(5) +3 = -50 +3 = -47
The table values are 13, 3, -7, -47.
What is the Compound interest on a 10,000 investment the earns 6% compound monthlyfor5 years
Answer:
The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest
Step-by-step explanation:
So the formula for this would be:
A = P(1+r/n)^nt
A = the amount of your principal plus interest, which is the total
P = stands for the principal, which is your original amount invested
r = shows the interest rate in decimal form
n = stands for the number of compounding periods
So to solve for the compound interest we would plug in our numbers in replacement for the letters

Answer: E
Step-by-step explanation:
need an answer, please need an answer, please
Answer:
Step-by-step explanation:
1) 6 and -5
x₁ + x₂ = 6 +(-5) = 1
x₁* x₂ = 6*(-5) = -30
x² -(x₁ + x₂)x + (x₁* x₂)=0
x² - x - 30 = 0
2) 4 and 7
x₁ + x₂ =4 + 7 = 11
x₁* x₂ = 4*7 = 28
x² - 11x + 28 = 0
3) 1 and -10
x₁ + x₂ = 1 +(-10) = -9
x₁* x₂ = 1*(-10) = -10
x² - 9x - 10 = 0
4) -9 and 0
x₁ + x₂ = -9 + 0 = -9
x₁* x₂ = 0
x² - (-9)x = 0
x² + 9x = 0
5)2 and 6
x₁ + x₂ = 2 + 6 = 8
x₁* x₂ = 2*6 = 12
x² -8x + 12 = 0
8) 2 +√3 and 2 - √3
x₁ + x₂ = 2+ √3 + 2 - √3 = 4
x₁* x₂ = (2 + √3)(2 - √3) = 2² - (√3)² 4 - 3 = 1
x² - 4x + 1 = 0

Step-by-step explanation:
Evaluate. {1−[−3−(5+4)]}⋅(−6)
Answer:
-78
Step-by-step explanation:
So we start with the innermost parentheses
(5+4) = 9
{1−[−3−(9)]} x -6
-3 - 9 = -12
{1 - [-12]}
Whenever you subtract a negative, the subtraction and negative cancel each other out, so it turns into addition
1 + 12 = 13
13 x -6 = -78
What are the values of x and y?
(9x - 19y)
(5x - 17)
(3x + 3)º
X =
y =
Answer: x = 10 and y = 3
Step-by-step explanation:
Due to the x rule, (5x - 17) = (3x + 3)
If we add 17 to both sides:
5x = 3x + 20
Take away 3x from both sides
2x = 20
Divide by 2:
X = 10
This means that (5x - 17) = (3x + 3) = 33
Since all angles must add to 360, the top angle = (360- (33*2)) /2
(360-66) /2
294 /2
147
This shows that 9x - 19y = 147
90 - 19y = 147
Minus 90 both sides
19y = 57
Y = 3
So, x = 10 and y = 3
PLEASE HELP PLEAAE HURRY ANS NO LINKS PLEASE I REALLY NEED THE ANSWER
Answer:
3(x+15) is the answer
Step-by-step explanation:
The equation x+15 repeats 3 times so you would have to create an equation to multiply x+15 3 times.
3x+15 is wrong because its only multiplying x by 3 and ignoring 15
x+45 is wrong because it is only multiplying 15 by 3 and ignoring x
x+15 is wrong because it is not multiplied by 3
3(x+15) is correct because it is the only answer that multiples 3 with both terms
Hope this helps
Answer:
Lets say that x is the number 5,
Step-by-step explanation:
5 divided by 15 = 0.33333333333
5 divided by 0.33333333333 = 15
5 + 15 + 5 + 15 + 5 + 15=60
(I know im all over the place with this, but this is just what i do)
60 - 15 = 45
15 + 45 = 60
I know this is random but maybe you may figure it out or get a random hint??, 3(x+15) is 3x + 45
PRETTY SURE ITS 3(x+15) Please give me brainliest i sat here for like 24 mins trying to figure this out :(
