i really need help with my math assignment it’s normal distributions and i need this to graduate tomorrow if anyone can help it would be deeply appreciated

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

The diagram represents the polynomial 4x2 + 23x – 72. what is the factored form of 4x2 + 23x – 72? (4x + 8)(x – 9) (4x – 8)(x + 9) (4x + 9)(x – 8) (4x – 9)(x + 8)

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cot of 61.6
