What is the number 212three in base-two form?

Answers

Answer 1

The correct answer is: B. 10111

To convert the number [tex]\(212_{\text{three}}\)[/tex] to base-two (binary) form, we need to first convert it to base-ten and then convert the base-ten number to base-two.

[tex]\(212_{\text{three}}\)[/tex] in base-ten:

[tex]\[ 212_{\text{three}} = 2 \cdot 3^2 + 1 \cdot 3^1 + 2 \cdot 3^0 = 18 + 3 + 2 = 23_{10} \][/tex]

Now, we convert [tex]\(23_{10}\)[/tex] to base-two:

[tex]\[ 23_{10} = 16 + 4 + 2 + 1 = 2^4 + 2^2 + 2^1 + 2^0 = 10111_{2} \][/tex]

Answer 2

Final answer:

The number 212 in base three (212three) converts to 17 in decimal, which is represented as 10001 in binary notation (base-two).

Explanation:

The number 212 in base three (2123) needs to be converted into base-two form (binary). Converting from base three to base two requires understanding each digit's place value in base three and then converting that to binary. Starting from the rightmost digit to the left, we have:

The units place (30), with a value of 2The threes place (31), also with a value of 2The nines place (32), with a value of 1

So, we have:

2123 = (1 × 32) + (2 × 31) + (2 × 30)

2123 = (1 × 9) + (2 × 3) + (2 × 1)

2123 = 9 + 6 + 2 = 17 in decimal.

Now we need to find the binary representation of 17:

17 divided by 2 is 8 with remainder 1 (20)8 divided by 2 is 4 with remainder 0 (21)4 divided by 2 is 2 with remainder 0 (22)2 divided by 2 is 1 with remainder 0 (23)1 divided by 2 is 0 with remainder 1 (24)

So, the binary equivalent is 1(24)0(23)0(22)0(21)1(20), which is 100012.

Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points)

Part C: Determine the axis of symmetry for h(x). (2 points)

Answers

Part A.

The given equation is:

y = x^2 + 6x + 7

By completing the square:

y = (x^2 + 6x + 9) + 7 – 9

y = (x + 3)^2 – 2

y + 2 = (x + 3)^2

 

Part B.

The vertex form of a parabola is in the form:

y – k = 4p (x – h)^2

Where (h, k) is the vertex (x, y) of the parabola.

Therefore the vertex: (-3, -2)

Since 4p = 1, a positive number, therefore the parabola opens up which makes the vertex (-3, -2) the minima of the graph.

 

Part C.

The Axis of Symmetry is the x - coordinate of the vertex which is x = - 3

Four students get 90s on a test, three get 70s, 2 get 60s and one gets an 80. what is the mean test score in this group?

Answers

The mean score will be given by:
mean=
mean=[90*4+70*3+2*60+80]/10
=[360+210+120+80]/10
=770/10
=77
the mean score is 77

Final answer:

The mean test score for the group is calculated by summing the products of each unique score and the number of students who received it, then dividing by the total number of students. In this case, the mean test score is 77.

Explanation:

To calculate the mean test score for the group, you multiply each score by the number of students who received it, then sum all those products, and finally divide by the total number of students. Four students scoring 90 would contribute 4 x 90 = 360 to the total sum. Three students scoring 70 contribute 3 x 70 = 210. Two students scoring 60 contribute 2 x 60 = 120. One student scoring 80 adds 80 to the sum. The total sum of all scores is 360 + 210 + 120 + 80 = 770. Since there are a total of 10 students (4 + 3 + 2 + 1), the mean score is calculated as 770 ÷ 10 = 77. Therefore, the mean test score in this group is 77.

help me create an extraneous radical equation please using this model!! :) thank you.
[tex]a \sqrt{x}+b + c = d[/tex]

I don't need you to solve it, just help me pick numbers for variable a, b, c, and d to create an extraneous solutuion

Answers

If you are sure that's exactly what the equation is:

b,c,d are all numbers, so indeed, focus on a single number, say 'e'. Also a can't be zero, or there is no equation at all! So, again all numbers can be grouped:

a*sqrt(x) + b+c=d ---> sqrt(x) = f, f some number.

x = f^2 is the solution.

To be extraneous, means that it does not solve the equation.

Why here? Because by definition in mathematics sqrt( f^2) is not f! but abs(f), that is:

sqrt(9)=3,

So you just need to set the numbers to -3: (thinking x=9)

2*sqrt(x) + 7 -4 = -3

this gives: sqrt(x) = -3, from which x= 9, but sqrt(9) = 3.

It's kind of tricky, because many forget the definition that sqrt(a^2) = abs(a).

The same does not happen when looking for roots.

You should ask your teacher to make sure this is what they want.

Let me say that usually extraneous solutions are those which come out after solving an equation but make no sense when substituted in the original equation. But with sqrt(x) and your so particular equation, there is nothing else to say.

x = -360/-8
x = 45 minutes <== plan A

5x + 3y = 360
5(45) + 3y = 360
225 + 3y = 360
3y = 360 - 225

Use newton's method to find the absolute minimum value of the function f(x)=x2+sinx correct to six decimal places.

Answers

The solution would be like this for this specific problem:

 

f(x) = x^2 + sin(x) 

f '(x) = 2x + cos(x) 

 

The minimum value is at f '(x) = 0, 

 

So, let g(x) = 2x + cos(x) 

Thus, g '(x) = 2 - sin(x) 

x(new) = x - g(x) / g '(x) 
or 
x(new) = x - [2x + cos(x)] / [2 - sin(x)] 

 

Calculation 

x1 = -0.5 - [2 * -0.5 + cos(-0.5)] / [2 - sin(-0.5)] 
= -0.4506266931 
x2 = -0.4501836476 
x3 = -0.4501836113 
x4 = -0.4501836113 

 

This value for x, f(x) = -0.2324655752. 


After converting to 6 decimal places: the minimum point is (-0.450184, -0.232466).

Final answer:

To find the absolute minimum value of f(x)=x^2+sin(x), use Newton's method with Newton-Raphson iteration x_{n+1} = x_n - f(x_n)/f'(x_n). Start with an initial guess and iterate until the result converges to six decimal places, ensuring the second derivative at the critical point is positive.

Explanation:

To find the absolute minimum value of the function f(x)=x^2+sin(x) correct to six decimal places, we can use Newton's method. Newton's method helps to find successively better approximations to the roots (or zeroes) of a real-valued function. First, we need to find the derivative of the function, which gives us f'(x) = 2x + cos(x). We are looking for a critical point where the derivative is zero because this could indicate a potential minimum (or maximum).

Starting with an initial guess, we can apply the Newton iteration formula x_{n+1} = x_n - f(x_n)/f'(x_n) to find a better approximation. In this case, let's choose an initial guess close to the root of f'(x). Since we do not have the specific initial guess, we would theoretically pick a value near the expected minimum and iterate until the difference between consecutive approximations is less than the desired tolerance, which is the change in six decimal places.

The Newton-Raphson iteration would be applied repeatedly until convergence is seen at six decimal places. Note that in practice, one must also check the second derivative f''(x) at the found critical point to confirm it is a minimum (it should be positive).

The quadratic function y = –10x2 + 160x – 430 models a store’s daily profit (y) for selling a T-shirt priced at x dollars. What equation do you need to solve to find the selling price or prices that would generate $50 in daily profit? What method would you use to solve the equation? Justify your choice.

Answers

Daily profit, y, as a function of T-shirts sold, x, is
y = -10x² + 160x - 430

In order to generate $50 in daily profits, the number of T-shirts sold is determined by solving the equation
-10x² + 160x - 430 = 50

Divide through by -10.
x² - 16x + 43 = -5
x² - 16x + 48 = 0

Answer:
This quadratic equation can be solved by factorization.

Explanation:
Note that
48 = 4 x 12, and
4 + 12 = 16
Therefore
x² - 16x + 48 = (x - 4 )(x - 12 ) = 0
The solutions are
x - 4 = 0  => x = 4, and
x - 12 = 0  => x = 12


a. The required equation is x² - 16x + 48 = 0

b. I would use factorisation to solve it and the selling prices that would generate a daily profit of  $50 are $4 and $12 respectively.

a.

The required equation is x² - 16x + 48 = 0

The required equation

Since the quadratic function y = -10x² + 160x - 430 models a store’s daily profit (y) for selling a T-shirt priced at x dollars. Since we require a profit of $50, then y = 50.

So, y = -10x² + 160x - 430

-10x² + 160x - 430 = 50

-10x² + 160x - 430 - 50 = 0

-10x² + 160x - 480 = 0

Dividing through by -10, we have

x² - 16x + 48 = 0

So, the required equation is x² - 16x + 48 = 0

b.

I would use factorisation to solve it and the selling prices that would generate a daily profit of  $50 are $4 and $12 respectively.

The method

To determine the method you would use to solve the equation, you would need to determine the value of the discriminant.

Discriminant

For a quadratic equation ax² + bx + c = 0, the discriminant is D = b² - 4ac

Since x² - 16x + 48 = 0 and its discriminant D = (-16)² - 4 × 48

= 256 - 192

= 48

= 64 > 0 and is a perfect square, so it is factorizable. The equation would have real and distinct roots,

So, x² - 16x + 48 = 0

x² - 4x - 12x + 48 = 0

x(x - 4) - 12(x - 4) = 0

(x - 4)(x - 12) = 0

x - 4 = 0 or x - 12 = 0

x = 4 or x = 12

I would use factorisation to solve it and the selling prices that would generate a daily profit of  $50 are $4 and $12 respectively.

Because 7 > 5, It rounds to 1.751702.

Answer:

The answer is 1.751702

Step-by-step explanation:

In this number there are 11 decimal places which can be found after the decimal point.

1.75170179212

As we want 6 decimal places, we need to look at the digit to the right of sixth decimal place. Therefore:

1.75170179212

So, in this case, the digit in the seventh place is a '7'.

If we want to round a number, there are two ways:

If the digit is less than 5, you leave the sixth decimal as it is.If the digit is equal or greater than 5, you add 1 up to the sixth decimal.

As the seventh decimal is a '7' which is greater than '5'.

We add a 1 to the Sixth decimal place.

As the sixth decimal place was a '1'. When we round it, it will be a 2
