Which transformation of figure abcdefgh results in figure a'b'c'd'e'f'g'?

1)a translation 4 units left

2)a reflection over the x-axis

3)a 90° clockwise rotation about the origin

4)a reflection over the y-axis

need plz

4)A reflection over the y-axis.

Step-by-step explanation:

Given :  figure ABCDEFGH results in figure A'B'C'D'E'F'G'.

To find : Which transformation used in figures.

Solution : We have given that  figure ABCDEFGH and  figure A'B'C'D'E'F'G'.

By the reflection rule over y axis : (x ,y ) →→ ( -x ,y ).

We can see from diagram coordinates of  A ( 2 ,-2 ) reflect in to A'( -2, -2),

B ( 4 ,-2)  reflect in to B'( -4, -2) and so on,

Therefore, 4)A reflection over the y-axis.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
