Answer:
To simplify computations, mathematicians like to fit an angle's triangle into a circle with radius r = 1.
Step-by-step explanation:
Because the number 1 is called "the unit" in mathematics, a circle with a radius of length 1 is called "the unit circle".
Answer:
Step-by-step explanation:
<u>Is this equation written correctly?:</u>
<u></u>
v(x)=12-2x-5.8
v(x) = -2x+6.2
v(-2) = -2(-2)+6.2
<u>v(-2) = 2.3</u>
v(0) = -2(0)+6.2
<u>v(0) = 6.2</u>
v(-5) = -2(-5)+6.2
v(-5) = 10+6.2
v(-5) = 16.2
