Okay so this means g(x) is 12 times f(x)
g(x)=f(12x)= 12(6x-10)
g(x)=72x-120
1,600 800+800=1,600 this is your answer
Answer:
1. Cellphone screen - plane
2. edge of a wall - line
3. grain of sell - point
4. strand of straight hair - line
5. Tip of a crayon -point
Step-by-step explanation:
1. Cellphone screen - It represents a 2 D plane surface. Hence it is a representation of a plane
2. edge of a wall - It is representation of a line
3. grain of sell - It is representation of a point
4. strand of straight hair - It is representation of a line
5. Tip of a crayon - It is representation of a point
Answer:
Pretend that H is the midpoint of AB, connect O and H
=> OH is the median of ΔOAB
Since we know that OA = OB => ΔOAB is an isosceles triangle
=> OH is also the height of ΔOAB
=> ∠OBA = ∠OAB = (180° - ∠AOB)/2 = (180° - 120°)/2 = 60°/2 = 30°
Now look at ΔOHB (that you create by connecting O and H)
We have:
cos30° = BH/OB
=> BH = cos30° · OB = √3/2 · x = (√3 x)/2
Because we have H as the midpoint of AB, we know that:
AB = 2 · BH = 2 · (√3 x)/2 = √3 x
So the answer is B
