729-243=486

486×3=1458

1458+729=2187(x=7)

1458×3=4374

4374+2187=6561(x=8)

4374×3=13122(average rate of change for interval 8 to 9)

13122+6561=19683(x=9)

Ans: B

a once-popular children's doll is slowly declining in popularity. the quartic function f(x)-0.002x^4 0.025x^3-0.364x^2-7.243x 86
Vilka [71]

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:

f(x) = -0.002x^4 - 0.025x^3 - 0.364x^2 - 7.243x + 86.993

Estimate how many dolls were sold in 2001.

2001 is 2001 - 1993 = 8 years after 1993, so this is f(8).

f(8) = -0.002*8^4 + 0.025*8^3 - 0.364*8^2 - 7.243*8 + 86.993 = 10.361

10,361 dolls were sold in 2001.

How to algebraically find the limit of a function as x approaches infinity?
Sauron [17]

Well... One way you can do this is by testing a set of arrays and see the trend. If I chose to find what y1 is in (100, y1) and what y2 is in (101, y2), I would find the difference between y2 and y1. If y2 - y1 is positive, this means there is a positive relationship and y is also approaching POSITIVE infinity. A negative relation means that it is approaching NEGATIVE infinity. However, it could be approaching a single number like "4" for instance, and you just need to plug in the right number of data sets to make that educated guess.

Formula Example:
5 + 1 / (x + 1) will always approach 5 because "1 / (x + 1) will approach 0".

Hope this helps.

Anwar says that the shape below is a parallelogram. is he correct that a kite is a parallelogram explain
My name is Ann [436]
Short answer: No afraid not.

Opposite sides of a parallelogram must be equal and parallel. The opposite sides of a kit are neither. To make sure you understand, measure the upper left side and the lower right side. The upper left is shorter than the  lower right (even though these sides are opposite one another).

It you extend the upper left line upward and do the same thing to the lower right,  you will get two lines that meet. No parallelogram will do that.
