In boot camp, a cadet must use a rope swing to cross an obstacle without
falling into the water hazard below. unfortunately, they miss the platform on
the other side and swing back to where they started. if it takes the cadet 4.5
seconds to swing from one side of the obstacle to the other and back, how
long is the rope swing? use the formula:
t=2pie ,square root l over 9.8

The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. find the surface area and the volume of a cube with a side length of 6m

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
