calculus
Each of the sides of a square (S) with an area of 16 is bisected and a smaller square (S2) is constructed using the bisected parts as vertices. The same process is carried out on S2 to construct an even smaller square (S3). What's the area of S3? (Draw a diagram, please?)

Thank you very much!

2 planes parallel to the base of a pyramid cut the pyramid at 1/4 and 2/3 of the height as measured from the base up. If the volume of the pyramid is 100 cubic inches, what is the volume of the middle piece to the nearest tenth?

draw it, it always helps you will see that you need to use Tangent "Opposite over adjacent" tan(angle)=65/20

A tow truck is connected to a 1500 kg car by a cable that makes a 27 degree angle to the horizontal. If the truck accelerates at 0.58 m/s^2, what is the magnitude of the cable tension? Neglect friction and the mass of the cable.

my K value was right. My mistake was when I plugged my values from my ICE table into the expression I used 0.25x^2/1.35-x instead of just x^2/1.35-x. Everything else was right.Thanks anyway
