Consider the arithmetic sequence. -9, -2, 5, 12,... Given that the sequence is represented by the function Rin), what are the values of A1) and the common difference? A (1) = -9 Common difference : 7
B. 1) = -2 Common difference : -7
C. (1) = -2 Common difference: 7
D. A1) = -9 Common difference : -7​

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:

the awnser is visionary

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
