Jen is 4/10 meters taller than her sister. Her sister is 9/10 meters tall. How tall is Jen?

mariarad [96]

Add 4/10 to 9/10.

9/10 + 4/10 = 13/10

Simplify 13/10 into a mixed number by subtracting 10 from the numerator and turning it into a whole.

13/10 ⇒ 1 3/10

<u>Jen is </u><u>1 3/10 meters</u><u> tall.</u>

a polynomial function has a zero at -1,2, and 7( all multiplicity 1) write a function in standard form that could represent this

s2008m [1.1K]

Answer:

$x^3-8x^2+5x+14$

Step-by-step explanation:

We have been given the zeroes of polynomial which are -1,2,7

That means the factors are (x+1) (x-2) (x-7)

When we want to a polynomial from zeroes we multiply the factors

$(x+1)(x-2)(x-7)$

$(x+1)(x^2-7x-2x+14)$

$(x+1)(x^2-9x+14)$

$(x^3-9x^2+14x+x^2-9x+14$

$x^3-8x^2+5x+14$

Hence, the required polynomial is:

$x^3-8x^2+5x+14$
