The value of a and b in terms of equation are; a = 3 + b and b = a + 18.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
We are given polynomial, h(t) = 2t - at + bt + 4 represents Mr. Bill's height in metres at 't seconds. "-Mr." Bill is rapidly approaching a tall brick wall which is 100 metres high and will reach the wall in 3 seconds.
h = 100 metres
t = 3 seconds
Now substitute the values;
h(t) = 2t - at + bt + 4
100 = 2(3) - a(3) + b(3) + 4
100 = 6 - 3a + 3b + 4
3a + 90 = 3b
We need to find out if Mr. Bill will clear the wall or slam into it!
h(t) = 2t - at + bt+4 has a remainder of 9 when divided by (t-1) and a remainder of "-36" when divided by (t+2).
When t = 1
Then;
h(t) = 2t - at + bt + 4
9 = 2(1) - a(1) + b(1) + 4
9 = 6 - a + b
a = 3 + b
When time t = -2
Then; h(t) = 2t - at + bt + 4
-36= 2(-2) - a(-2) + b(-2) + 4
-36 = -4 + 2a - 2b + 4
-18 = a - b
b = a + 18

Answer:
15.035 years
Step-by-step explanation:
The exponential function to calculate population growth is
P(t) = Poe^kt
P(t) = Population size after t years = 3.6 million
Po = Initial population size = 2.1 million
k = growth rate = 3.65% = 0.0365
t = time in years = ???
Hence:
3600000 = 2100000 × e ^0.0365t
Divide both sides by 2100000
3600000/2100000 = e^0.0365t
1.7142857143 = e^0.0365t
Find the log of both sides
Log 1.7142857143 = log (e^0.0365t)
Log 1.7142857143 /Log 0.0365 = t
t = 15.035 years
