Answer:
255 minutes or 4 hours and 25 minutes.
Step-by-step explanation:
1. yes , it is it is exponential growth, because 1.04^x, and 1.04>1
2. 1.04=1+0.04
0.04 =4% rate of growth
P=5/25=1/5
That's your answer :) Also, in case you are confused, the answer is 1/5 :P
The area of
equals to the sum of areas of the triangles it consists of. So,
![A(\mathrm{PQRST})=A(\mathrm{PQR})+A(\mathrm{PRS})+A(\mathrm{PST})=10.2+11.5+16.3=\boxed{38}](https://tex.z-dn.net/?f=A%28%5Cmathrm%7BPQRST%7D%29%3DA%28%5Cmathrm%7BPQR%7D%29%2BA%28%5Cmathrm%7BPRS%7D%29%2BA%28%5Cmathrm%7BPST%7D%29%3D10.2%2B11.5%2B16.3%3D%5Cboxed%7B38%7D)
2/3 is the simplification form
