Patricia is studying a polynomial function f(x). three given roots of f(x) are -11 - sqrt 2, 3 + 4i, and 10. patricia concludes that f(x) must be a polynomial with degree 4. which statement is true?

D. Patricia is not correct because both 3 – 4i and -11+ √2i must be roots.

Step-by-step explanation:

The question is obviously incomplete, but if the polynomial has all real coefficients, then Patricia is partially right in that the polynomial has at least degree 4. Complex roots occur in conjugate pairs, so if 3+4i is a root, then so is 3-4i. So we know at a minimum that we can write

where is some real number.

529 and 531

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:
