Answer: 8^2 18^2

Step-by-step explanation: The way that you figure out the power is by multiplying the 4x2=8 than the 9x2=18 than you raise them both to the second power.

Answer:

The coordinates of the original triangle are (2,4). (4,1) and (1,1)

Step-by-step explanation:

About the origin, I have to rotate a triangle 90° counterclockwise. Then I translate its image 1 unit left and 2 units down.

The vertices of the final image are (-5,0), (-2,2), and (-2,-1).

We need to get the vertices of the original triangle.

So, start from a triangle with vertices (-5,0), (-2,2), and (-2,-1) and do the reverse to get the original triangle.

So, we will translate the image triangle by 1 unit right and 2 units up and we will get the triangle with vertices (-5 + 1, 0 + 2), (- 2 + 1, 2 + 2) and (- 2 +1, - 1 + 2) ≡ (-4,2), (-1, 4) and (-1,1).

Now, we have to rotate this intermediate triangle by 90° clockwise.

Therefore, the coordinates of the original triangle are (2,4). (4,1) and (1,1) (Answer)

{Since, for 90° rotation the coordinates of all the vertices will interchange their location (i.e. x-value to y-value and y-value to x-value) and a negative sign will be added to the y-coordinate of the interchanged coordinates}

Answer:

16. -197 < -110

17. 167 > -65

18. Mercury, Earth, Mars, Jupiter, Uranus, Neptune

Step-by-step explanation:

It can help to plot these temperatures on a number line. The ones farther to the left are less than ones to their right.

16. -197 < -110 . . . Uranus < Jupiter

17. 167 > -65 . . . Mercury > Mars

18. Reading the graph from right to left, the order greatest to least is ...

Mercury, Earth, Mars, Jupiter, Uranus, Neptune

Not surprisingly, this is the order of these planets outward from the sun.
