The function below models the correlation between the number of hours a plant is kept in sunlight x in the height y, in mm to which it grows. y = 2 + 4x what does the y-intercept of this function represent? a.) the original height of the plant was 4 mm. b.) the original height of the plant was 2 mm. c.) the height of the plant increases by 2 mm for every hour of sunlight it receivesd.) the height of the plant increases by 4 mm for every hour of sunlight it receives.

   B.) the original height of the plant was 2 mm.

Step-by-step explanation:

The given function below models the correlation between the number of hours a plant is kept in sunlight 'x' in the height 'y', in mm to which it grows.

To find the y intercept of the function, we substitute the value of x =0 , we get

Hence, the original height of the plant = 2 mm

Therefore, the y intercept of the function is (0,2)

i.e. the original height of the plant = 2mm.

it 2

step-by-step explanation:

8^1/3=2

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:
