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.

vivado [14]

Answer:

-25.

Step-by-step explanation:

What is the difference of outputs for any two inputs that are one value apart?

If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).

Output 2 - Output 1:

Output 3 - Output 2:

Output 4 - Output 3:

Output 5 - Output 4:

So the difference of outputs for any two inputs one value apart are

<u>Answer</u>:

h = 16  ||    solution after squaring: x = -0.683<em> or </em>x = -7.32

<u>steps by fieranswererft</u>:

Given: x^2+8x+5=0

Take half of the x term and square it

  • [8*\frac{1}{2} ]^2=16

  • x^2+8x+16=- 5+16

  • (x+4)^2=-5+16

  • (x+4)^2=11

  • x+4 = \pm \sqrt{11}

  • x = \pm \sqrt{11}-4

  • x = -0.683<em> or </em>x = -7.32
