Use a graphing utility to graph the polar equation. Find an interval for θ for which the graph is traced only once

r = 2(1 − 2 sin(θ))

-infinity<θ< ???

Use a graphing utility to find the rectangular coordinates of the point given in polar coordinates.

(7.8, 2.18)

with (6.2, 2.47) the answer was

(-4.85,3.86)

Rotate the axes to eliminate the xy-term in the equation. Then write the equation in standard form. (Use xp for x' and yp for y' in your answer. Rotate the coordinate axes through an angle θ with 0 ≤ θ ≤ π/2.)

2x^2 – 3xy – 2y^2 + 5 = 0

So a=2 c= -2 b= -3 and i don't know how to find angle once i get cot 2tetha = -4/3

center at origin

Foci: (±10, 0); asymptotes: y = ± 3/4x

The probability of a sales representative making a sale with any one customer is 1/2. The sales representative makes twelve contacts a day. To find the probability of making three sales, evaluate the term shown below in the expansion of (1/2 + 1/2)^12. (Round your answer to four decimal places.)

12C3 (1/2)^3 (1/2)^9

12C3 (1/2)^3 (1/2)^9

To find the probability of making three sales, evaluate the term shown below in the expansion of (1/2 + 1/2)^12. (Round your answer to four decimal places
