identify each classification of the real number system that can describe the set of numbers shown {3, 9, 147, 400}

) Integer
) Irrational
) Real
) Rational
) Whole
) Natural​

Answers

Answer 1

Step-by-step explanation:

all of these 4 numbers are

integer (whole numbers positive and negative).

real (every whole number can be written as e.g. 3.0 and is part of the real numbers).

rational (as any whole number can be written as e.g. 3/1 and is part of the rational numbers).

whole (no fractions).

natural (they are in the set of [1, 2, 3, ... infinity) ).

the only thing here they are not is irrational, as to be irrational they would need to have an infinite sequence of digits after the decimal point without any repeating pattern.

Show that f(x)=12x^3-32x^2+17 has a zero between 2 and 3.

Answers

Answer:

Step-by-step explanation:

You could graph it. I'll do that at the bottom. What you need is a value that is - on either 2 or 3 and a plus on the other one.

y=12*2^3 - 32x^2 + 17

y = 12 * 8 - 32*2^2 + 17

y = 96 - 128 + 17

y = -15

Now when x = 3 should give you something above the x axis

y = 12*3^3 - 32*9 + 17

y = 324 - 288 + 17

y = 53

What this indicates is that somewhere between 2 and 3 the graph crosses the x axis. The graph should indication that.

Answer:

  (A) -4 and -2

Step-by-step explanation:

The constant in the function tells you f(0) = 5.

You know that the positive leading coefficient means the value of f(x) will be negative for x-values smaller than some number. The offered answer choices indicate the value x = -4 is a lower bound on the value of c. So, -4 < c < 0, for sure.

To further refine the interval, you would need to know f(-2) and/or f(-1).

  f(-2) = (-2)³ -2(-2) +5 = -8 +4 +5 = 1

Then -4 < c < -2.

Answer:

Angle B is 52 degrees

Step-by-step explanation:

The outer angle 112 adds up with the inner angle to make 180. So angle C is 68. All the angles should add up to 180, so add them all together.

68+4y+3y+7 = 180

75+7y = 180

7y = 105

y = 15

To double-check this, plug 15 into y and add up all the angles, it should add up to 180.

3(15)+7 = 52

4(15) = 60

68+60+52 = 180

Angle 5 will be 150 degrees

Answer:

Angle 5 should be 60

Step-by-step explanation:

Angle 2 and angle 4 are the same because they are Corresponding Angles. so if the lines m and n equal 180 then you subtract 120 from 180 and you get 60 so 5 ,7, 1 and 3 are 60 degrees

The number of times an action is performed between every other person in a group can be calculated using the relation [tex] \frac{n(n - 1)} {2}[/tex] which is 136 times

Using the formular ;

[tex] \frac{n(n - 1)} {2}[/tex] n = number of persons = 17

[tex] \frac{n(n - 1)} {2} = \frac{17(17 - 1)} {2}[/tex]

If g(x)=3x-2, find g(3)-g(-8)

Answers

Answer:

33

Step-by-step explanation:

1. Let's solve for g(3)

Step 1: Plug in the value of x.

[tex]g(3)=3(3)-2[/tex]

Step 2: Simplify.

[tex]g(3)=9-2[/tex] [tex]g(3)=7[/tex]

2. Let's solve for g(-8)

Step 1: Plug in the value of x.

[tex]g(-8) = 3(-8)-2[/tex]

Step 2: Simplify.

[tex]g(-8) = -24 - 2[/tex] [tex]g(-8)=-26[/tex]

3. Now, let's subtract g(-8) from g(3).

[tex]g(3)-g(-8)[/tex] [tex](7)-(-26)[/tex] [tex]7+26[/tex] [tex]33[/tex]

Therefore, the answer is 33.

Answer:

33

Step-by-step explanation:

g(x) = 3x - 2

g(3) = when x of g(x) function is 3.

g(3) = 3(3) - 2

g(3) = 9 - 2

g(3) = 7

g(-8) = 3(-8) - 2

g(-8) = -24 - 2

g(-8) = -26

g(3) - g(-8)

7 - (-26) = 33
