Because cos(x) = 1/sec(x), therefore
cos(48) = 1/1.4945 = 0.6691
The angle 48° is in quadrant 1, therefore cos, sin, tan, sec, csc and cot functions are all positive.
Note that sin(90° - x) = cos(x).
Therefore
sin(90 - 48) = cos(48)
sin(42°) = cos(48°) = 0.6691
Because csc(x) = 1/sin(x), therefore
csc(42°) = 1/sin(42°) = 1/0.6691 = 1.4945
Answer: 1.4945
10 + 1/2*4*48 => 10 + 2*48 => 10 + 96 = 106.
Answer:
Emilio needs less than 1 stick of butter
Step-by-step explanation:
Emilio needs 1/2 stick of butter to make cornbread . He also needs 1/4 stick of butter to make apple muffins . Does Emilio need more than I stick of butter to make both recepes or less than 1 stick of butter ? How do you know?
Cornbread = 1/2 stick of butter
Apple muffins = 1/4 stick of butter
Total sticks of butter = cornbread + apple muffins
= 1/2 + 1/4
= (2+1) / 4
= 3/4 stick of butter
= 0.75 stick of butter
0.75 stick of butter is less than 1 stick of butter
Therefore,
Emilio needs less than 1 stick of butter
