Yoo pls ! g(a)=2a-1 h(a)=3a-1 find (g•)

For this, you will be multiplying g(-4) and h(-4) together.

Firstly, do the multiplications within the parentheses:

Next, do the subtractions:

Lastly, multiply -9 and -13, and your answer should be

$79500

step-by-step explanation:

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:
