P=Ae^kt
225 = 210 * e^(k*(1990-1980)
225/210=e^10k ln(225/210)=10k
k=ln(225/210)/10=0.0069
P = 210*e^(0.0069t)
for 2000 ===> t = 2000-1980=20
P = 210*e^(0.0069*20)
P=241.0749=241
The answer is A (6 √2) Because your formula ends up being 7^2 + x^2 = 11^2
7^2 + x^2 = 11^2
Becomes
49 + x = 121
So subtract 49 on both sides to get x by itself
x = 72
And Find the square root of x
72 = 6 √2

-(10/7)
Step-by-step explanation:
See attached graphic. The slope of the Green Line is cut off in the problem photo, but can be calculated from the graph to find the slope of the Red Line. The answer options are on drugs; pick the one that looks closest.
