Years since the tree was planted, x

Height of tree in feet, y

2, 17, 3, 25, 5, 42, 6, 47, 7, 54, 9, 69

Using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?

Answer/explanation:

There is no good prediction for the height of the tree when it is 100 years old. If you analyze careful in details the regression calculator you realize that it probably will not valid that far in to the future say 100 years.

Divide x^4+3x^3-2x^2+4 by x-2<br><br>which answer shows the correct synthetic division and quotient
arsen [322]

Answer:

option-A

\frac{x^4+3x^3-2x^2+4}{x-2}=x^3+5x^2+8x+16+\frac{36}{x-2}

Step-by-step explanation:

we are given

divisor is

=x^4+3x^3-2x^2+4

Dividend is

=x-2

so, we can use synthetic division

so, we can write our expression as

\frac{x^4+3x^3-2x^2+4}{x-2}=x^3+5x^2+8x+16+\frac{36}{x-2}

so,

option-A

Prime factors of 100:2*2*5*5
No factors are in common, so this is the most simplified state.

What are the zeros of the function g(x) = (x + 6) (x – 4)(x + 2) ?
vitfil [10]

9514 1404 393

Answer:

  x in {-6, -2, 4}

Step-by-step explanation:

The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.

  x +6 = 0   ⇒   x = -6

  x -4 = 0   ⇒   x = 4

  x +2 = 0   ⇒   x = -2

The zeros of the function are the x-values -6, -2, and 4.
