Answer:
81.7
Step-by-step explanation:
90.7-18 divided by 2 = 81.7 or 82 simplified
Answer:
The equation i.e. used to denote the population after x years is:
P(x) = 490(1 + 0.200 to the power of x
Step-by-step explanation:
This problem could be modeled with the help of a exponential function.
The exponential function is given by:
P(x) = ab to the power of x
where a is the initial value.
and b=1+r where r is the rate of increase or decrease.
Here the initial population of the animals are given by: 490
i.e. a=490
Also, the rate of increase is: 20%
i.e. r=20%
i.e. r=0.20
Hence, the population function i.e. the population of the animals after x years is:
P(x) = 490(1 + 0.200 to the power of x
Answer
54 degrees
Step-by-step explanation:
Using angle sum property(angles in a triangle add up to 180),
y+y+72=180
2y+72=180
2y=180-72
2y=108
y=108/2
y=54 degrees
