5x-y=-1 + -5x+3y=25 for two variable elimination quiz

Mathematics
1 answer:
MakcuM [25]3 years ago
6 0

Answer:

(\frac{11}{5},12)

Step-by-step explanation:

The system is

5x-y=-1

-5x+3y=25

We the two equations to get:

5x+-5x+-y+3y=25+-1

We simplify t get

2y=24

We divide both sides by 2 to get:

y=12

We now substitute y=12 in to the top equation to get:

5x-12=-1

5x=11

x=\frac{11}{5}

Set up, but do not evaluate, the integral that represents the length of the curve given by
netineya [11]

Answer:

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Step-by-step explanation:

Arc length of a parametric curve is:

L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt

x = t + cos t, dx/dt = 1 − sin t

y = t − sin t, dy/dt = 1 − cos t

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Or, if you wish to simplify:

L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt

L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt
