Find the work done by the force f(x)=3x+7 in moving a particle from x=1 to x=3
andrew11 [14]

Answer:

26

Step-by-step explanation:

W = ∫ f(x) dx

W = ∫₁³ (3x + 7) dx

W = (1.5x² + 7x) |₁³

W = (1.5(3)² + 7(3)) − (1.5(1)² + 7(1))

What is the perimeter of a triangle with the side lengths 4 cm, 6 cm, and (3y-2) cm?
jek_recluse [69]

Answer:

Step-by-step explanation:

P = 4 + 6 + (3y - 2)      Remove the brackets

P = 10 + 3y - 2            Combine

P = 8 + 3y

Note 3y must be less than 8. That's because 2 sides of any triangle must be larger than the 3rd side or else you don't have a triangle.
