If ax^3+bx^2+cx+d is divided by (x-2) the coefficients of quotient are 4,5,6 and the remainder is 0, then the polynomial is

Step-by-step explanation:

Polynomial = (4x² + 5x + 6)(x - 2) = 4x³ - 3x² - 4x - 12.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

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:
