Find the following quotient, and write the quotient in rectangular form, using exact values. 8(cos 90° + i sin 90°)/3(cos 30° + i sin 30°) Express the complex number in polar form

Express the complex number in polar form and use DeMoivreʹs Theorem to find the given power. Write your answer in rectangular form. Give your answer in exact form unless otherwise specified. 29)... Find the angle between the given vectors to the nearest tenth of a degree.

Find the angle between the given vectors to the nearest tenth of a degree. a = 7i + 2j,   b = -6i + 6j In how many seconds will the projectile strike the ground?

A projectile is fired with an initial velocity of 500 feet per second at an angle of 45° with the horizontal. In how many seconds will the projectile strike the ground? (Round your answer to the... How far apart are A and B (to the nearest yard)?

Two points A and B are on opposite sides of a building. A surveyor chooses a third point C 76 yd from B and 102 yd from A,  with angle ACB measuring 55.6°.  How far apart are... How far apart are A and B (to the nearest yard)?

Two points A and B are on opposite sides of a building. A surveyor chooses a third point C 76 yd from B and 102 yd from A,  with angle ACB measuring 55.6°.  How far apart are... How much does the boat weigh?

A force of 501 lb is required to pull a boat up a ramp inclined at 25° with the horizontal.  How much does the boat weigh? With what frequency does the spring oscillate?

Suppose that a weight on a spring has initial position s(0) and period P. If s(0) = -5 in. and P = 2.5 sec, find a function s given by s(t) = a cos ωtthat models the displacement of the weight... Through how many degrees will the larger wheeler rotate if the smaller one rotates 230°?

Two wheels are rotating in such a way that the rotation of the smaller wheel causes the larger wheel to rotate. The radius of the smaller wheel is 10.6 centimeters and the radius of the larger... I got a test question that was asking me to find the x intercept of the function (8-4x)/(x^2-6x+8)

I know that you can solve for the x intercept by solving the numerator, but when I did that and got 2, it said the correct answer was that there was no x intercept. Can someone explain this...

Trying to figure out if this is the best answer to this  question
