How many complex and real roots are in the problem (x+10)^9.

Katena32 [7]

Answer:

9 roots

Step-by-step explanation:

(x+10)^9 = 0

If you would multiply it out, the highest power is x^9 so the equation has 9 roots

Solving (x+10)^9 =0

Taking the 9th root of each sdie

x+10 = 0

x = -10

The root is -10 with multiplicity of 9

Question 8 Multiple Choice Worth 1 points)

bogdanovich [222]

Answer:

Option B.

Step-by-step explanation:

Note: The function f(x) is not in correct format it must be $f(x)=3^x$ .

It is given that two different plants that grow each month at different rates are represented by the functions f(x) and g(x).

Let as consider the two functions,

$f(x)=3^x$

$g(x)=5x+12$

Now, table of values is

Month(x) $f(x)=3^x$ $g(x)=5x+12$

1 3 17

2 9 22

3 27 27

4 81 32

From the above table it is clear that in first and second month the height of the f(x) plant is less than of g(x).

In month 3, heights are equal.

In month 4, height of the f(x) plant exceed that of the g(x) plant.

Therefore, the correct option is B.

Given that p²,q² are two roots of x²-x+16=0. <br>Form another equation with roots 1/p,1/q.

statuscvo [17]

Answer:

x² -3/4x +1/4 = 0

Step-by-step explanation:

Consider the two equations in factored and expanded forms:

(x -p²)(x -q²) = x² -(p²+q²)x +p²q² = 0 ⇒ p²+q² = 1, p²q² = 16

and

(x -1/p)(x -1/q) = x² -(1/p+1/q)x +1/(pq) = 0

Consider the squares of the sum and product of roots:

constant term: (1/(pq))² = 1/(p²q²) = 1/16 ⇒ 1/(pq) = √(1/16) = 1/4

x-term: (1/p +1/q)² = (p +q)²/(pq)² = (p² +q² +2pq)/(p²q²)

= (p² +q²)/(p²q²) +2/(pq)

= 1/16 +2/√16 = 9/16 ⇒ (1/p +1/q) = √(9/16) = 3/4

Then the equation with roots 1/p and 1/q is ...

x² -3/4x +1/4 = 0
