Toby is making a scale model of the battlefield at Fredericksburg. The area he wants to model measures about 11 mi by 7.5mi. He plans to put the model on a 3.25 ft by 3.25ft square table. On each side of the model he wants to leave at least 3 inches between the model and the t...

Physics
A thin, uniform rod is hinged at its midpoint. To begin with, one half of the rod is bent upward and is perpendicular to the other half. This bent object is rotating at an angular velocity of 6.8 rad/s about an axis that is perpendicular to the left end of the rod and parallel...

I was wondering if I could check my answers with someone. I'm a bit confused with interest. I put stars next to the answers I chose. Thank you. An interest rate is a special type of (1 point) loan. **price. bank. service. 2. How does a compound interest rate differ from a ...

Conjecture
what conjecture could be made and proven from the following? sin(3x)/sin(x) - cos(3x)/cos(x) I put it on my calculator and based on the graph I say that as it crosses the y axis the values get larger.

Difficult Trig Word Problem
sorry y(t) =4e(then the exponent -3t) all times sin(2pi*t)

Difficult Trig Word Problem
The displacement of a spring vibrating in damped harmonic motion is given by y(t) = 4e^-3t sin(2pi*t) where y = displacement and t = time with t greater than/equal to zero. Find the time(s) when the spring is at its equilibrium position (y=0). The number "e" is Euler...

Precalculus 2
Similiarly to a question I asked previously I took the same approach. the problem is: what value(s) of theta solve the following equation? cos(theta)sin(theta) - 2 cos(theta) = 0? I let Cos theta = X and sin theta = X unfortunately I end up with something completely odd. Can a...

Triangles
solve any triangles satisfying alpha = 20 degrees b = 10 c = 16 b and c are 2 side values and if I use the pythagorean theorem and I get 18.18? Did I do this right?
