Suppose that the position of one particle at time is given by x1=3sin t, y1 = 2 cos t, 0 ≤ t ≤ 2π and the position of a second p
Mashcka [7]

Answer:

there is no collision between the particles

Step-by-step explanation:

for the first particle

x1=3sin t, y1 = 2 cos t, 0 ≤ t ≤ 2π

for the second particle

x2 = -3 + cos t, y2 = 1 + sin t, 0 ≤ t ≤ 2π

then for the collision

x1=x2 → 3*sin t = -3 + cos t → sin t= -1 + (cos t)/3→ 1+ sin t = (1/3)cos t  

y1=y2 → 1 + sin t = 2 cos t → (1/3)cos t  = 2 cos t →(1/3) = 2

since 1/3 ≠ 2 there is no collision between the particles

Which property can be used to expand the expression -2(3/4x+7)?
Mademuasel [1]

Answer:

C

Step-by-step explanation:

The distributive property in algebraic terms is

a(b + c) = ab + ac

given the expression

- 2(\frac{3}{4} x + 7) ← multiply each term in the parenthesis by - 2

= - \frac{3}{2} x - 14
