The coordinates of points A
and B are (–7, 5) and (4, –3), respectively.
What is the distance between the points,
rounded to the nearest tenth?

Distance=13.60

Step-by-step explanation:

The Distance between the two points in coordinate system is find by using the distance formula.

If two points and are given:

For the points:

The distance between the points is 13.60

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

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:
