1000e^.07t = 1800

can someone solve this and expalin how they did it because i am so confused. i will make it 25 points!

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).

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
