Answer:
B = 61°
C = 61°
Step-by-step explanation:
The sum of all the angles is 360.
When the angles are formed with straight lines like shown the angles back to back are equivalent or equal.
So you can take 119 and add it by itself to get 238.
You then get 360 and subtract 238 which gets you 122.
Then divide 122 by two and you have the answer for both b and c which is 61.
Answer:
a) 0; b) 4![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
Step-by-step explanation:
a) To compute f o g (0), first evaluate g(x) for x=0 and then evaluate f for x=g(0).
![f \circ g (0)=f(2 \cdot 0)=f(0)=0^2](https://tex.z-dn.net/?f=f%20%5Ccirc%20g%20%280%29%3Df%282%20%5Ccdot%200%29%3Df%280%29%3D0%5E2)
b) To compute a mathematical expression for f o g do the same but instead of 0 use x,
![f \circ g (x) = f( 2 \cdot x)= (2 \cdot x )^2](https://tex.z-dn.net/?f=f%20%5Ccirc%20g%20%28x%29%20%3D%20f%28%202%20%5Ccdot%20x%29%3D%20%282%20%5Ccdot%20x%20%29%5E2)
The answer to that operation is 13
Answer:
3
Step-by-step explanation:
The absolute value means spaces away from zero. -3 is 3 spaces away and 3 is also 3 spaces away. Hope this helps!
