This is how you solve the three questions. hope this helps.
Complete question :
The exponential model A=16.2e^0.01t describes the population, A, of a country in millions, t years after 2003. What was the population in 2003?
Answer:
16.2 million
Step-by-step explanation:
Given the equation :
A=16.2e^0.01^t
Where, t = number of years after 2003
The population in year 2003 ; can be obtained thus ;
t = 2003 - 2003 = 0
Put t = 0 in the equation :
A(0) =16.2e^0.01^0
A(0) = 16.2 * 1
A(0) = 16.2
Hence, population in 2003 is 16.2 million
Answer:
1.6% shrinkage
Step-by-step explanation:
907,340 - 875,435 = 31,905
31,905 / 1,988,345 = .0160 = 1.6%

Answer:
-[9\-8 + k] + 5 + 6k - 3k²
Step-by-step explanation:
Since the divisor is in the firm of <em>-</em><em>c</em><em> </em><em>+</em><em> </em><em>x</em><em>,</em><em> </em>where <em>-</em><em>c</em><em> </em>gives you the OPPOSITE terms of what they really, we can use Synthetic Division. The way to do this is to put our <em>c</em><em> </em>in the top left corner, list all the coefficients in our dividend, then perform our operations:
8| -3| 30 | -43 | -49
-- ↓ -24 48 40 >> -[9\-8 + k] + 5 + 6k - 3k²

Remainder
When we perform our operations using synthetic division, we always bring down the first term, then we multiply that term by <em>c</em><em>,</em><em> </em>then depending on the outcome, the integer will term us whether or next operation is to subtract or add. We then repeat this process all the up until we reach the end. If we have a remainder, we set it over the divisor given to us in the problem. After this, our quotient will always be one degree less than what was in the dividend. In the problem, our highest degree term was 3, so our quotient will have a highest degree term if 2, then you keep going down the chart over the next coefficients:
-3k² + 6x + 5 - [9\k - 8]
