The exponential model A=831.1 e^0.022t describes the population,A, of a country in millions, t years after 2003. Use the model t
KIM [24]

Answer:

831.1 million

Step-by-step explanation:

If the exponential model describes the population after 2003 and we must determine the population of the country in 2003 then t=0 because the time only starts after 2003:

A=831.1\cdot{e^(0.022\cdot{0})}

e to the power of 0 is equal to 1:

A=831.1\cdot{e^(0.022\cdot{0})}=831.1\cdot{1}=831.1

The population in 2003 is 831.1 million

Does 24, 7, and 26 form a right triangle
const2013 [10]

Answer:

No. It is an obtuse triangle.

Step-by-step explanation:

If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.
