Answer:
Move the constant to the right. Step 3: Take half of the x-term coefficient and square it. Add this value to both sides. Step 4: Simplify right side. Step 5: Write the perfect square on the left. Step 6: Take the square root on both sides of the equation. Step 7: Solve for x. Solve equation x2 - 4x + 3 = 0.
Step-by-step explanation:
No it doesn’t not represent a function
D is right since a ton equals 2000 pounds
Use tan 2x = 2tan x / (1 - tan^2x)
so tan 60 = 2 tan 30 / 1 - tan^2 30 = 1.7321
cot 60 = 1 / 1.7321 = 0.5774 Answer
