The lowest point has a y coordinate of 2. The highest point has a y coordinate of 6. The difference is 6-2 = 4. Cut this in half to get 4/2 = 2 which is the amplitude. This is the vertical distance from the midline (y = 4) to either the peak point or the valley point.

There are 4 sticks, you pick up one stick. How many sticks are left

LenaWriter [7]

There are 3 sticks because:

4 sticks is the total and when you take away 1 stick, it is

4 - 1, which equals 3 sticks

So, the answer is 3 sticks are left.

Question: If u are in high school, why did you ask this question? You already know 4-1=3. Im guessing it was either a joke, or u were helping other people get points. If it is the second one, thx!!

Triangle FGH is translated using the rule (x,y) > (x+3,y-1). What are the coordinates of H ?

Masteriza [31]

Answer: $H'(4,-3)$

Step-by-step explanation:

For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

A Translation is defined as a transformation in which the figure is moved a fixed distance in a fixed direction. In this kind of transformatiosn the size and shape do not change and the figure is not flipped.

In this case you know that the Pre-Image is the Triangle FGH.

You can identify in the picture that its vertex H has these coordinates:

$H(1,-2)$

Where:

$x=1\\y=-2$

Since the rule is:

$(x,y)$ → $(x+3,y-1)$

You can substitute the coordinates of H into the given rule in order to find the coordinates of H'. This is:

$H'=(1+3,-2-1)=(4,-3)$

The difference between two numbers is less than 0.

Serhud [2]

The 2 numbers cannot be positive but the 2 numbers can be both positive and negative like: 2+(-3)= -1. Both numbers can also be negative like: (-3)-(-2)=-1.
