Item 1 How do you know when a radical expression is in simplest form? Choose all that apply. No radicands contain fractions. No radicands have terms with exponents. No radicands appear in the numerator of a fraction. No radicands appear in the denominator of a fraction. No radicands have perfect nth powers as factors other than 0. No radicands have perfect nth powers as factors other than 1.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

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:
