Answer: It is being dilated by a scale factor of 1/3.
Step-by-step explanation:
The pre-image has the coordinates (0,0) (6,0) (6,-3) and (0,-3) and a transformation has been applied to it to get the coordinates of the image to be (0,0) (2,0) (2,-1) ( 0,-1)
Looking at the coordinates we can see that to get from 6 to 2 you will have to multiply by 1/3 and to get from -3 to -1 you will have to multiply by 1/3.
This means that pre-image was dilated by a scale factor of 1/3.
Answer:
Troll 1: Knight
Troll 2: Knave
Troll 3: Knight
Step-by-step explanation:
Troll 3's statement must be true because if they can only be knights or knaves, unless all of them are knaves, at least one must be a knight. Thus, Troll 3 is a knight.
If Troll 2 is a knight, then Troll 1 is knave, but if that were the case Troll 1's statement would be true, and since knaves do not tell the truth, this assumption is incorrect.
If Troll 2 is a knave, Troll 1 is a knight and his statement can be disregarded since it is conditioned to the possibility of him being a knave.
Therefore, Trolls 1 and 3 are knights and Troll 2 is a knave.
Acid is 0.2*5 = 5* 1/5 = 1 liter. We should multiple mass and concentration (in this conditions). So, 1 liter.
9.945*10^30 Kg - 1.7901*10^32 Kg
This is on average what the mass of a black hole.
I think you mean to say

. If

is in the third quadrant, then

and

. Recall that

We expect

to be negative, so we take the negative root. We end up with

We also know to expect

, so

By definition, we have

and so
