<em>The population on 30th day will be </em><em>134836</em><em>.</em>
Step-by-step explanation:
This is a case of exponential growth. The general form of exponential function is,
where, a and b are constants.
The data points from the question are
Putting the values in the function,
for
----------1
for
------2
Dividing equation 2 by 1,
Putting the value of b in equation 1,
Now the function becomes,
Putting x=30, we get
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = , then
cos30° = =
=
=
( cross- multiply )
2 AC = 12 ×
= 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
