According to the rational root theorem, the numbers below are some of the potential roots of f(x) = 10x3 29x2 – 66x 27. select a

exis [7]

The actual roots of the function $f(x)=10x^{3}+29x^{2} -66x+27$ are -9/2, 3/5 and 1.

Given function $f(x)=10x^{3}+29x^{2} -66x+27$ .

Function is a relationship between two or more variables expressed in equal to form.

The roots of a polynomial function are the zeroes of the polynomial function. A polynomial function is a function that involves only non negative integer powers in an equation.

The polynomial function is given as:

$f(x)=10x^{3}+29x^{2} -66x+27$

factorize the above function

$f(x)=(2x+9)(5x-3)(x-1)$

Now put the function f(x) equal to zero.

f(x)=(2x+9)(5x-3)(x-1)

split the function means put all the expressions equal to zero as under:

(2x+9)(5x-3)(x-1)=0

solve each for the value of x

x=-9/2,x=3/5,x=1

Hence the roots of the function $f(x)=10x^{3} +29x^{2} -66x+27$ are which are also the values of x are -9/2,3/5,1.

A jar contains sugar. The jar and the sugar have a total weight of 850 g. Anna uses 2/3 of the sugar. The jar and the sugar now

maria [59]

Answer:

$J = 370g$

Step-by-step explanation:

Given

Represent the weight of the Jar with J and the sugar with S

Initially, we have:

$J + S = 850g$

After 2/3 of sugar is removed we have:

$J + S -\frac{2}{3}S= 530g$

Required

Determine the weight of the jar

$J + S = 850g$ --- (1)

$J + S -\frac{2}{3}S= 530g$ --- (2)

Simplify (2)

$J + S -\frac{2S}{3}= 530g$

Take LCM

$J + \frac{3S - 2S}{3}= 530g$

$J + \frac{S}{3}= 530g$

Make S the subject in (1)

$J + S = 850g$

$S = 850g - J$

Substitute 850g - J for S in $J + \frac{S}{3}= 530g$

$J + \frac{850g - J}{3}= 530g$

Multiply through by 3

$3 * J + 3*\frac{850g - J}{3}= 530g * 3$

$3J + 850g - J= 1590g$

Collect Like Terms

$3J - J= 1590g-850g$

$2J= 740g$

Make J the subject

$J = \frac{1}{2} * 740g$

$J = 370g$

<em>The jar weighs 370g</em>

If g(x)= square root x-2-3 what is the range of g(x)? A.(0,♾) B. (-1,♾) C. [-2,♾) D. [-3,♾)

Sladkaya [172]

Answer:

Step-by-step explanation:

g(x) = √(x - 2) - 3

The range is all the possible values of g(x). Since we can't take the square root of a negative number, the lowest that g(x) can be is:

g(x) = √0 - 3

g(x) = -3

The highest that g(x) can be is:

g(x) = √∞ - 3

g(x) = ∞

So the range is:

[-3, ∞)
