Find the area of the square pyramid represented by this net.

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?
