F(n)=2n+5
g(n)=n²-1
Find f(-3) ⋅ g(-3)

she will travel a distance in the range of 3 - 11 miles

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:

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
