Answer:

C. Cos(28) = \frac{15}{17}

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

Cos(\theta) = \frac{Adjacent}{Hypotenuse}

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

Cos(28) = \frac{15}{17}

Help Please?! I don’t know how to do this
Fofino [41]

Domain 0≤x≤12   this means the domain (x values) are between x=0 and x=12 and you started measuring the degree of temperature starting at a time of 0 and stopped measuring the temperature at a time of 12 hours


Range -4≤y≤4   this means the range (y values) are between y=-4 and y=4. The range is referring to the degree in celcius based on what time you measured it


Hope this helps!
