Answer:
Step-by-step explanation:
The formula for a geometric series is aₙ = a₁rⁿ⁻¹.
This is analogous to the exponential series y = a₀rⁿ.
The difference it that, in a geometric series, n must be positive.
Thus, the graph of a geometric series starts somewhere on the y-axis and either increases exponentially or decreases asymptotically to the x axis.
In Graph A , the successive values of y are 5/2⁰, 5/2¹, 5/2² and 5/2³. This is an example of exponential decay.
In Graph B, the successive values of y are 3¹, 3² and 3³. This is an example of exponential growth.
In Graph C, the successive values of y are 2¹, 2², 2³, and 2⁴, another example of exponential growth.
In Graph D, the successive values of y are 1, 2.5, 4, 5.5. and 7. There is a constant difference of 1,5, so this represents an arithmetic series.
could represent a geometric series.
Answer:
Option B - and
Step-by-step explanation:
Given : The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride, x. The Splash water park charges an entry fee of $60 and an additional $3 per ride, x.
To find : Which system of equations could be used to determine the solution where the cost per ride of the two amusement parks, y, is the same?
Solution :
Let x be the number of rides and
y be the cost per ride.
According to question,
The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride.
The equation form is
The Splash water park charges an entry fee of $60 and an additional $3 per ride.
The equation form is
Therefore, The required system of equations form are
and
So,Option B is correct.
