Answer:
2 bears in 2020.
Step-by-step explanation:
We have been given that a new bear population that begins with 150 bears in 2000 decreases at a rate of 20% per year.
We will use exponential decay formula to solve our given problem as:
, where,
y = Final quantity,
a = Initial value,
r = Decay rate in decimal form,
x = Time
Upon substituting our given values in above formula, we will get:

, where x corresponds to year 2000.
To find the population in 2020, we will substitute
in our equation as:



Therefore, 2 bears are there predicted to be in 2020.
Since population is decreasing so population is best described as exponential decay.
The player has a total of 18 goals scored and 6 assists made.
<h3>
Equation</h3>
Equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of goals scored and y represent the number of assists. Since the combined goals and assist is 24, hence:
x + y = 24 (1)
Also:
2x + y = 42 (2)
From equation 1 and 2:
x = 18, y = 6
The player has a total of 18 goals scored and 6 assists made.

Adding two rational numbers results in a positive sum.
Answer:
0.431 inches
Step-by-step explanation:
We were given the following values:
Height the tennis ball was dropped = 100in
Rebound height = 58in
We have to find the rebound ratio
= 58in/100in = 0.58
The formula to be used
Height on nth bounce = Initial height × (Rebound ratio)ⁿ
Where n = number of bounce
Height on the 10th bounce = 100 × (0.58)^10
Height on the 10th bounce = 0.4308042069inches
Approximately, the height on the 10th bounce = 0.431 inches.
75% of 60
OF MEANS times
75/100 * 60
180/4
45
the answer is 45
