Answer:
Step-by-step explanation:
C^2=a^2+b^2-2abcosC
13^2=10^2+11^2-2×10×11×cos(°)
169=100+121-220cos(°)
220cos(°)=100+121-169
220cos(°)=52
cos(°)= 13/55
°=cos-1(13/55)
°=76.328°
I think it is 5.301 x 10^1
Answer:
- g(-x) = 70 +3x
- -g(x) = -70 +3x
- -g(-x) = -70 -3x
Step-by-step explanation:
Put the minus signs where the problem statement tells you. As with any function, the argument replaces the variable in the function definition. That is, for g(-x), you put (-x) where x is in the definition of the function.
g(-x) = 70 -3(-x) = 70 +3x
-g(x) = -(70 -3x) = -70 +3x
-g(-x) = -(70 -3(-x)) = -70 -3x
