The elephant population in Northwestern Namibia and Ethosha National Park can be predictedby the expression 2,649(1.045)^b where b is the number of years since 1995.
What does the value 2649 represent?
A. The predicted increase in the number of elephants in the region each year.
B. The predicted number of elephants in the region in 1995.
C. The year when the elephant population is predicted to stop increasing.
D. The percentage the elephant population is predicted to increase each year.
WILL GIVE BRAINLEST!!!!!!!
Answer:
b
Step-by-step explanation:
A. makes no sense because the elephant population increases less than 2649 in 6 years.
C. makes no sense because you shouldn't multiply the percent by the year you think the population will stop increasing.
D. the percentage is in the parentheses
The elephant population was 2649 in 1995 and the elephant increase each year by 4.5% (1.045 - 1).
Exponential functionAn exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the elephant population in Northwestern Namibia and Ethosha National Park b years since 1995.
Hence:
y = 2649(1.045)ᵇ
The elephant population was 2649 in 1995 and the elephant increase each year by 4.5% (1.045 - 1).

A fish is swimming at a constant rate toward the ocean floor. The equation
y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.
Which statement best describes the depth of the fish, given this equation?
A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.
C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
Answer:
C.
explanation: if the fish is swimming towards the ocean floor it's descending 7 meter per second because -7x is the constant and 3 is the y-intercept or where the fish started

Answer:
Give the guy above me brainliest he is right!
Step-by-step explanation:
The variable in the given expression is "k", the operation is division, and the constant is "8".
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.
The given algebraic expression is "StartFraction k Over 8 EndFraction". This expression consists of a fraction (k/8), which represents a division operation between two quantities.
Here, the numerator of the fraction is the variable "k" and the denominator is the constant "8".
So, the variable in this expression is "k", the operation is division, and the constant is "8".
Thus, "StartFraction k Over 8 EndFraction" is an algebraic expression that represents a division operation between the variable "k" and the constant "8".

Michael, his wife, and another couple when to Louisville Zoo to get out in the fresh air and see the animals. Each ticket cost x dollars and Michael had to pay $10 to park his car. The total price paid was $90. Write and solve an equation to determine how much each ticket cost.
Step-by-step explanation:
First of all PLEASE PAY ATTENTION in class.
Secondly, I'll show you the method now.
We know that they paid 10$ for their parking and $90 altogether. So we can remove $10 from the $90. This now makes it $80.
We know that Michael, his wife and 2 other people (a couple) went to the zoo, that makes it 4 people total. We can use this number to divide with $80 making it $20. This therefore means that it was 20$ per person.
Here is my explanation in method form.
x = [tex]\frac{90-10}{4}[/tex]
x = [tex]\frac{80}{4}[/tex]
x = 20
