Solve for a. Round to the nearest tenth, if necessary.

Step-by-step explanation:

tanx=12/18

x=arctan(12/18)

tan(90-x)=12/(a+5)

tan(90-arctan(12/18)=12/(a+5)

a+5=12/tan(90-arctan(12/18))

a=12/tan(90-arctan(12/18))-5

a=3

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

i think is g(1)=-1.

hope that i can
