Each transformation t below is linear. find the matrix of t with respect to the standard bases. in each case determine whether the matrix is a projection matrix. (a) for each v in r2, t (v) is the reflection of v across the line y = x.

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

The art class is planning to paint a mural on an outside wall. this figure is a scale drawing of the wall. width: 11 in length: 28 in unit rate: 1.5 ft per in. write the ratio of the area of the drawing to the area of the actual mural. write your answer as a unit rate. show that this unit rate is equal to the square of the unit rate 1.5 ft per in
