The answer should be B. The range is the Y Axis. and those points are on the Y Axis.
Answer:
7892 dolphins
Step-by-step explanation:
let P denote the dolphin population.
-Notice this is an exponential decay and is denoted as:
Where;
- is the population at time t
- t is the time
- r is the rate of decay or decrease in population
- is the initial population size.
#Given t=30yrs, =20000 and r=3.1%, the population after 30 years is estimated as:
Hence, the dolphin population after 30yrs is approximately 7892
Answer:
The solution is B) (3, 1).
Step-by-step explanation:
For the system of equations given, there are few different ways to solve. Since the second equation y = 2x - 5 is already solved for 'y', we can use substitution and place the expression '2x - 5' in for 'y' in the first equation and solve:
2x - 5 + 2 = x
We can also solve for 'y' in the first equation and then set the two equations equal to each other:
y + 2 - 2 = x -2 or y = x -2 so, 2x -5 = x - 2
Either way, when we solve for 'x', we get:
2x - 3 = x or -3 = -x, so x = 3
Plugging in the value of 'x' into the second equation:
y = 2(3) - 5 or y = 6 - 5 or y = 1
The ordered pair (x, y) would be (3, 1).
Answer:
(1,-5)
Step-by-step explanation:
recall that for any function g(x), we can equate the function to y,
i.e y = g(x), where any point (x,y) that satisfies the equation is considered a point on the graph
in our case we are given, that g(1) = -5, rearranging:
-5 = g(1)
if we compare this with the the equation above y = g(x),
we can see clearly that y = -5 and x = 1.
and from our reasoning given in the paragraph above, we can say that (1,-5) is a point on the graph.
A1 = 3 and an = an − 1 − 3
a1 = 2 and an = an − 1 + 0.5
