(1 point) A curve in polar coordinates is given by: r = 7 + 2 costheta.
Point P is at theta = {16 pi}/ {14}.

a.) Find polar coordinate r for P, with r > 0 and pi r =

b.) Find cartesian coordinates for point P.
x =

y =

c.) How may times does the curve pass through the origin when 0 \lt \theta \lt 2 \pi ?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

493 would be the correct answer

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
