A flight wheel 1.5 ft in diameter has an angular velocity of 8 rad / sec. Find the linear velocity of a point on the radian.

Give the value of x in the trigonometric equation:

cos^2 x + cot 2x = (1/2)

A 200.0g metal at 110°C is dipped into 500.0g of cold water at 10.0°C. If the resulting temperature of the mixture is 11.19°C, what is the specific heat of lead in cal/g °C?

Indicate whether the given expression is a polynomial or not.

1. square root of 5

2. 0

3, square root of (5x^2 + 6x^2)

Find the distance that the earth travels in one day in its path around the sun. Assume a year has 365 days and that the path of the earth around the sun is a circle of radius 93 million miles. (The path of the earth around the sun is actually an ellipse, however, has very small eccentricity, so it is nearly circular.)

A football player stands at a distance c behind the middle of the goal. He sees the angle of elevation of the nearer crossbar to be u and that of the farther one to be v. Show that the distance between the goals is c (tan u cot v - 1).

A wall extending east and west is 6 feet high. The sun has an altitude of 49 degrees 31’ and is 47 degrees 20’ east of south. Find the width of the shadow of the wall on level ground.

From a lighthouse a boat was sighted at sea with a bearing of N12°W (North 12 degrees West). The boat was traveling due east at 12 knots per hour. Fifteen minutes later it had bearing at N72°E (North 72 degrees East). How far was the boat from the lighthouse when last sighted?

Two ships leave a harbor at the same time. One ship is travelling N36° E (North 36 degrees East) at 12 mi/h; the other ship travels at 15 mi/h. After three and one-half hours, they are 46 mi apart. In which direction is the second ship traveling?

A moving point P remains always equidistant from Point 1 (-1,0) and Point 2 (0,-2). Express this fact by an algebraic equation.

I 2x + 5 I < I 3x - 7 I

(The Absolute Value of 2x+5 is less than the Absolute Value of 3x-7)

I need some help in this problem:

(x-5) (2-x) (2-3x) > 0

Find the equation of the line which has equal intercepts and passes through the point (-4,9).

A ball is thrown vertically upward from the top of a building 84 feet tall with an initial velocity of 70 feet per second. The distance S (in feet) of the ball from the ground after T seconds is

S = 96 + 80T - 16t^2

After how many seconds will the ball touch the ground?

Note: the problem is a quadratic equation...

A man rows 16 km upstream and back in 9 hours. He can row 1 km upstream in the same time that he can row 4 km downstream. Find the speed of the boat in still water and the speed of the current.

Representation:

x = rate of boat in still water

y = rate of current

x-y = upstream speed

x+y = downstream speed
