Answer:

We can say that the given equation has no extraneous solutions.

The correct option is A.) 0

Step-by-step explanation:

the given equation is [tex]\frac{9}{n^{2} +1} = \frac{n+3}{4}[/tex]

this equals to [tex]36 = (n^{2} +1)(n+3) = n^{3} + 3n^{2} + n + 3[/tex]

therefore [tex]n^{3} +3n^{2} +n+3 = 36 \hspace{0.3cm}\Rightarrow \hspace{0.3cm}n^{3} +3n^{2} +n-33=0[/tex]

Solving the equation through Newton-Raphson method we get n  [tex]\approx[/tex]  2.3845.

Answer:

53.284 kg

Step-by-step explanation:

62 kg - 8.716kg = 53.284 kg

Hope it helps you in your learning process.

Answer:

53,284 grams

Step-by-step explanation:

Kilograms resemble a thousand grams. Therefore:

Desk = 62000

Chair = 17000

So then the heaviest object is the desk and the lightest is the computer.

So:

62000grams -8716grams = 53284grams

Answer:

[tex]x = - 5[/tex]

or

[tex]x = 2[/tex]

Step-by-step explanation:

We want to solve ;

[tex] {12}^{ {x}^{2} + 5x - 4} = {12}^{2x + 6} [/tex]

We equate the exponents, because is the same on both sides.

[tex] {x}^{2} + 5x - 4 = 2x + 6[/tex]

We group and rewrite in standard form to get:

[tex] {x}^{2} + 5x - 2x - 4 - 6 = 0[/tex]

[tex]{x}^{2} + 3x- 10= 0[/tex]

[tex] {x}^{2} - 2x + 5x - 10 = 0[/tex]

[tex]x(x - 2) + 5(x - 2) = 0[/tex]

[tex](x + 5)(x - 2) = 0[/tex]

[tex]x = - 5 \: or \: x = 2[/tex]

The solutions are x = 2 and x = -5.

To solve the equation [tex]12^{x^{2} +5x-4}[/tex] = [tex]12^{2x+6}[/tex], we first note that since the bases are the same, we can equate the exponents:

⇒ x² + 5x - 4 = 2x + 6.

Next, we move all terms to one side to form a quadratic equation:

⇒ x² + 5x - 4 - 2x - 6 = 0

Simplifying this gives us:

⇒ x² + 3x - 10 = 0

We can now solve this quadratic equation using the quadratic formula, which is defined as:

⇒ x = (-b ± √(b² - 4ac)) ÷ 2a

For our equation, a = 1, b = 3, and c = -10. Substituting these values into the quadratic formula:

⇒ x = (-3 ± √(3² - 4 × 1 × (-10))) ÷2 × 1

⇒ x = (-3 ± √(9 + 40)) ÷ 2

⇒ x = (-3 ± √49) ÷ 2

⇒ x = (-3 ± 7) ÷ 2

This gives us two solutions:

⇒ x = (4) ÷ 2 = 2

⇒ x = (-10) ÷ 2 = -5

So, the solutions are x = 2 and x = -5.

Answer: 200

Step-by-step explanation:

120 divided by 3/5 is the same thing as 120 times 5/3.

So 120 x 5 = 600

And 600 divided by 3 is 200

The result of the division 120 divided by 3/5 is : 200.

Here, we have,

given that,

What is 120 divided by 3/5

we know that,

120 divided by 3/5 is the same thing as 120 times 5/3.

i.e. 120 ÷ 3/5

=> 120 × 5/3

now, we know that,

So 120 x 5 = 600

=> 600/3

And 600 divided by 3 is 200.

so, we get,

Hence, The result of the division 120 divided by 3/5 is : 200.

The polygon that is formed is a rectangle. Because all sides are horizontal or vertical line segments, she can count to find the distance. She should find the distance of each side and add them together. The total distance around the rectangle is 18 units.

Step-by-step explanation:

The calculation of the distance between the points is simplified, given

that the points are on the same perpendicular or horizontal line.

Correct response:

The given points can be presented as follows;

A(-2, 2), D(-2, -2), B(3, 2), and C(3, -2)

By observation, given that there are two pairs of points that have the

same x-coordinates, and two pair of points have the same y-coordinates,

we have;

The distance between two points is given by the difference between the variables that are not the same as follows;

Distance between point (-2, 2), and (-2, -2), AD = 2 - (-2) = 4

Distance between points (3, 2), and (3, -2), BC = 2 - (-2) = 4

Distance between points (-2, -2), and (3, -2), CD  = 3 - (-2) = 5

Distance between points (-2, 2), and (3, 2), AD = 3 - (-2) = 5

Final answer:

To find the total number of heartbeats in an hour, multiply the heartbeats per minute by 60. For Judy, her heart beats around 4200 times in an hour.

Explanation:

Judy's heart beats 70 times a minute. To calculate how many times her heart beats in an hour, you can use the following formula:

Heartbeats per hour = Heartbeats per minute x 60 minutes

Heartbeats per hour = 70 x 60 = 4200 times

25.8

6 out of 10 is 60% so 60% percent of 43 is 25.8

The height of the tree is 25.8 feet which is casting a shadow of 43 feet long.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A tree casts a shadow that is 43 feet long, and boy cast shadow of 10 feet who is 6 feet tall.

Assuming the height of the tree to be x.

∴ 43 : 10 : : x : 6.

43/10 = x/6.

10x = 258.

x = 25.8 feet.

So, the height of the tree is 25.8 feet.

Answer:

The given expression simplifies to 84x - 16y - 35

Step-by-step explanation:

The given equation is 2 ( 14x - 3y + 28x - 5y - 17.5)

The given equation simplifies to

28x - 6y + 56x - 10y  - 35

which is equal to

84x - 16y - 35

The expression 2 (14x - 3y + 28x + 12.2 - 5y - 17.5) simplifies to 84x - 16y - 10.6.

The expression that is equivalent to 2 (14x - 3y + 28x + 12.2 - 5y - 17.5) can be simplified using the distributive property and combining like terms.

First, distribute the 2 to each term inside the parentheses:

2(14x - 3y + 28x + 12.2 - 5y - 17.5) = 28x - 6y + 56x + 24.4 - 10y - 35

Next, combine like terms:

28x + 56x = 84x

-6y - 10y = -16y

24.4 - 35 = -10.6

So, the simplified expression is 84x - 16y - 10.6.
