Answer:

he has 10 type of each coin

Step-by-step explanation:

Total number of cents in possession is calculated as;

= 25 + 10 + 5

= 40 cent

Total amount in possession = $4

                                               = 400 cent

Since he has equal number of each cent, let this equal number be "y";

40cent (y) = 400cent

40y = 400

divide both sides by 40

\frac{40y}{40} = \frac{400}{40} \\\\y = 10

Therefore, he has 10 type of each coin

How many times is 5 x 10^6 larger than 5 x 10^4
gayaneshka [121]
<h3>Answer:</h3>

By <em>100 times</em>.

Step-by-step explanation:

Each time something is in Scientific Notation, to every power of 10 something is multiplied by, it grows by 10 times.

By knowing that, if both equations use the same starting number, you can minus the notation section from the larger value, to find the answer.

10^6 - 10^4 = 10^2 ---> 100 times.

Hope that helps, :)

Find all the zeros of f(x) help please
Licemer1 [7]

Since f(6)=0, by the remainder theorem this means that <em>x</em> - 6 divides <em>f(x)</em> exactly. This means there are constants <em>a</em>, <em>b</em>, and <em>c</em> such that

\dfrac{f(x)}{x-6} = ax^2 + bx + c

Multiplying both sides by <em>x</em> - 6 gives

f(x) = (x-6)(ax^2+bx+c) \\\\ 2x^3-19x^2+45x-18 = ax^3 + (b-6a)x^2 + (c-6b)x - 6c

Then <em>a</em>, <em>b</em>, <em>c</em> satisfy

\begin{cases}a=2 \\ b-6a=-19 \\ c-6b=45 \\ -6c=-18\end{cases}

and solving this system gives <em>a</em> = 2, <em>b</em> = -7, and <em>c</em> = 3.

So, we have

2x^3-19x^2+45x-18 = (x - 6) (2x^2 - 7x + 3)

The quadratic term can be factored as

2x^2 - 7x + 3 = (2x - 1)(x - 3)

which leaves us with

f(x) = (x-6)(2x-1)(x-3)

so that the zeros of <em>f(x)</em> are 6, 1/2, and 3.
