Vladimir [108]
F=5.77X10^9(1.032^(y-1985)), we want to know when this is:

2.2X10^12=5.77X10^9(1.032^(y-1985))

381.2825=1.032^(y-1985)

ln(3,812825)=(y-1985)ln(1.032)

ln(3.812825)/ln(1.032)=y-1985

y=1985+ln(3.812825)/ln(1.032)

y≈2027.5  

So GDP will reach 2.2 trillion during the year 2027.

Help!!
klio [65]

Answer:

The answer is 14.

Step-by-step explanation:

Since all of the angles of a triangle add up to be 180, then all you have to do is add the 2 angles together that you have and subtract that number from 180. For example 141+25=166, so, 180-166=14. 14 would be the measure of the third angle.
