False.

e is an irrational number, then it cannot be the ration of two integer numbers.

That expression is only an approximation to the value of e.

How many complex roots does the polynomial equation have? −3x4−7x+17=0
zimovet [89]

1) There are two complex roots. A is correct.

2) The function has three real zeros. The graph of the function intersects the x-axis at exactly three locations. D is correct

3) There are four complex roots. B is correct.

4) C is correct.

5)

Step-by-step explanation:

1) Number of complex root.

We can not factor it completely. Because it's prime equation. We will make the graph of  and then see the x-intercept of the graph.

Because number x-intercepts are the zeros of polynomial. Please see the attachment for graph. In graph we can see it cuts only two points but their highest degree is 4. Maximum possible roots are 4 but only 2 are real and 2 are complex.  

Thus, There are two complex roots.

2) This is cubic polynomial function.

Maximum number of zeros should be 3.

Please see the graph with attachment.

Zeros is a value of x where graph cuts x-axis. In graph we can see graph cuts x-axis at three points.

Thus, The function has three real zeros. The graph of the function intersects the x-axis at exactly three locations.

3) This is 4th degree polynomial.

Maximum number of zeros should be 4.

Please see the graph of polynomial.

Zeros is a value of x where graph cuts x-axis. In graph we can see doesn't cut x-axis at any points.

Thus, The function has four complex zeros. The graph of the function does not intersects the x-axis at any point.

4) We are given 3 degree polynomial. We need to factor it. First we split middle term and then factor it.

Now we factor quadratic part using quadratic formula

Complete factor of f(x)

Thus,

5) This is cubic polynomial. We need to factor it.

First we make two group and then factor it

Thus, complete factor of f(x) is (x+3)(x+4i)(x-4i)

There are nine tennis balls and three cans what is the rate of number of tennis balls to number of cans
Gennadij [26K]

Answer:

That's a simple question.

Well, we know that the number of tennis ball are 9 which are to be put in 3 cans

So the  the rate of number of tennis balls to number of cans will be= number of balls/number of cans= 9/3


In order to find out the number of balls per can just simplify them= number of balls/number of cans =9/3 = 3 balls per can

So there will also be 3 tennis balls in one can

Find the probability distribution for the following function: P(x) = x/10 for x = 3, 5, and 7
Gemiola [76]

Answer:

3/10. 1/2 and 7/10

Step-by-step explanation:

For P(x) = x/10

When x = 3;

Then;

P(3) = 3/10

When x = 5

Then;

P(5) = 5/10

       = 1/2

When, x = 7

Then;

P(7) = 7/10

What is the equation?
zavuch27 [327]

Answer:

\displaystyle 5x + 6y = 72\:or\:y = -\frac{5}{6}x + 12

Step-by-step explanation:

Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 1⅕ becomes −⅚, and we move forward with plugging the information into the Slope-Intercept formula:

\displaystyle -8 = -\frac{5}{6}[24] + b \hookrightarrow -8 = -20 + b; 12 = b \\ \\ \boxed{y = -\frac{5}{6}x + 12}

To write this in Linear Standard Form, perfourm he following:

y = −⅚x + 12

+ ⅚x + ⅚x

___________

⅚x + y = 12 [We cannot leave the equation this way, so multiply the equation by the denominatour to eradicate the fraction.]

6[⅚x + y = 12]

\displaystyle \boxed{5x + 6y = 72}

I am joyous to assist you at any time.
