Answer:
6x - 2
Step-by-step explanation:
f(2x) = 3(2x) - 2
f(2x) = 6x - 2
Area of a triangle is 0.5* perpendicular height* base
0.5*4*8
Where four is the perpendicular height and eight is the base
Therefore, area is equal to 16
Answer:
1/3
Step-by-step explanation:
= y2-y1/x2-x1
3-2/1+2
1/3
I believe the correct answer is 45 degrees. The smallest positive angle <span>θ in QI for which tan θ = 1 would be 45 degrees. We obtain it as follows:
</span>tan θ = 1
<span>θ = tan^-1 (1)
</span>θ = 45 degrees
Hope this answers the question. Have a nice day.
