Answer: -2.85
Step-by-step explanation:
To convert 22/20 into a decimal, we must multiply it by 5 to get a denominator of 100.
5(22/20)= 110/100= 1.10
So now lets solve the equation.
-1.75-1.10 = -2.85
Answer:
For 0° ≤ x ≤ 360° we have:
x=0, 360, arccos(1/6), -arccos(1/6)
Step-by-step explanation:
Replace cos(x) by y
6y²-7y+1=0
6y²-6y-y+1=0
6y(y-1) -(y-1)=0
(y-1)(6y-1)=0
Roots:
y=1, cos(x)=1, x=0 and 360
y=1/6, cos(x)=1/6, x=arccos(1/6) and x=-arccos(1/6)
