If sin θ = 1 over 4 and tan θ > 0, what is the value of cos θ? (1 point) negative square root of 15 over 4 negative square root of 15 over 4

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

[2, 2.5)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)

(2.5, 3]

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:

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
