Answer:
10,361 dolls were sold in 2001.
Step-by-step explanation:
Number of dolls sold in x years after 1993:
The number of dolls sold in x years after 1993 is given by:
Estimate how many dolls were sold in 2001.
2001 is 2001 - 1993 = 8 years after 1993, so this is f(8).
10,361 dolls were sold in 2001.
Answer:
graph A
Step-by-step explanation:
A graphing calculator can plot this function for you.
If you divide numerator and denominator by 25, you get ...
r = 1/(0.4 -sin(θ))
This will have asymptotes at θ = arcsin(0.4). At those values of θ, the value of r will change sign, so the graph cannot be a parabola or ellipse.
The graph of the hyperbola is the appropriate choice.
