Answer:

d. x=-1,2,\:or\:5

Step-by-step explanation:

The given equation is;

x^3-6x^2+3x+10=0

To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator.

The corresponding function is

f(x)=x^3-6x^2+3x+10

The solution to x^3-6x^2+3x+10=0 is where the graph touches the x-axis.

We can see from the graph  that; the x-intercepts are;

(-1,0),(2,0) and (5,0).

Therefore the real solutions are:

x=-1,2,\:or\:5

Compare the values 4x107 is what times as much as 4x103
dezoksy [38]

Answer:

10^{4}

Step-by-step explanation:

4 x 10^7 is 40000000

4 x 10^3 is 4000

We are told that 4x10^7 is something times as much as 4x10^3

So we will work backwards to find the answer,

If you divide 40000000 by 4000 you will get 10000

10000 is the same as 10^4
