If 1 more than 5 times a number is 26, what is the number

Answer:

The answer is 16

Step-by-step explanation:

The value of x is approximately 5.4 when x^3 -10x = 100

The equation is given as:

x^3 -10x = 100

Using trial by error, we keep testing for the value of x that is true for x^3 -10x = 100

After several attempts, we have:

x = 5.4 (approximately)

Substitute 5.4 for x in x^3 -10x = 100

5.4^3 -10 * 5.4 = 100

Evaluate

103.5 = 100

Approximate

100 = 100

This means that x is approximately 5.4 when x^3 -10x = 100

A solution to the equation x^3 −10x=100 using the trial and improvement method is approximately x=5.3 (rounded to 1 decimal place).

let's use the trial and improvement method to find a solution for the equation

x^3 −10x=100.

Start with a reasonable guess for x. In this case, it's often helpful to start with small integers.

Substitute the guess into the equation and see if it satisfies the equation.

Let's try

5^3 −10×5=125−50=75

The result is not equal to 100. Since the result is less than 100, we need to increase our guess.

Let's try

6^3 −10×6=216−60=156

The result is still not equal to 100. Since the result is now greater than 100, we need to decrease our guess.

Let's try

5.5^3 −10×5.5=166.375−55=111.375

This result is still greater than 100, so we need to try a smaller value.

5.2^3 −10×5.2=140.608−52=88.608

Now, this result is closer to 100. We can continue to refine our guess.

Let's try

5.3^3 −10×5.3=150.097−53=97.097

This result is getting closer to 100. We can keep refining our guess, but for the sake of brevity, let's stop here.

So, a solution to the equation x^3 −10x=100 using the trial and improvement method is approximately x=5.3 (rounded to 1 decimal place).

Answer:

[tex]5 {y}^{2} - 80[/tex]

Step-by-step explanation:

The given polynomials are:

[tex]5 {y}^{2} - 80[/tex]

and

[tex]y + 4[/tex]

Let us factor the first polynomial to get:

[tex]5 {y}^{2} - 80 = 5( {y}^{2} - 16)[/tex]

We need to rewrite as difference of two squares:

[tex]5 {y}^{2} - 80 = 5( {y}^{2} - {4}^{2} )[/tex]

We can now factor to get:

[tex]5 {y}^{2} - 80 = 5( {y} - 4)(y + 4)[/tex]

So the least common multiple of

[tex]5( {y} + 4)(y - 4) \: and \: (y + 4) \: is \: 5( {y} + 4)(y - 4) = 5 {y}^{2} - 16[/tex]

Answer:

NF = 16 units

Step-by-step explanation:

∵ N is the in-center of ΔABC

∴ N is equidistant from the sides AB, BC and CA

- That means the perpendicular segments from N to AB, BC

   and AC are equal

∴ ND = NE = NF

∵ ND = 6x - 2

∵ NE = 3x + 7

- Equate them to find x

∴ 6x - 2 = 3x + 7

- Subtract 3x from both sides

∴ 3x - 2 = 7

- Add 2 to both sides

∴ 3x = 9

- Divide both sides by 3

∴ x = 3

- Substitute the value of x in ND to find its length

∵ ND = 6(3) - 2 = 18 - 2

∴ ND = 16 units

∵ ND = NE = NF

∴ NF = 16 units

Step-by-step explanation:

Step 1:

The total of the angles in any triangle is 180°.

So to determine the third angle of the given triangles, we subtract the sum of the other two sides from, 180°.

The third angle = 180° - (the first angle + the second angle).

Step 2:

For triangle ABC,

[tex]m\angle B=180^{\circ}-(\angle A+\angle C)[/tex],

[tex]m\angle B=180^{\circ}-(83^{\circ} + 56^{\circ}) = 180^{\circ} - 139^{\circ} = 41^{\circ}.[/tex]

So [tex]m\angle B= 41^{\circ}.[/tex]

For triangle DEF,

[tex]m\angle F=180^{\circ}-(\angle D+\angle E)[/tex],

[tex]m\angle F=180^{\circ}-(61^{\circ} + 49^{\circ}) = 180^{\circ} - 110^{\circ} = 70^{\circ}.[/tex]

So [tex]m\angle F= 70^{\circ}.[/tex]

Step 3:

For triangle GHI,

[tex]m\angle H=180^{\circ}-(\angle G+\angle I)[/tex],

[tex]m\angle H=180^{\circ}-(49^{\circ} + 70^{\circ}) = 180^{\circ} - 119^{\circ} = 61^{\circ}.[/tex]

So [tex]m\angle H = 61^{\circ}.[/tex]

For triangle JKL,

[tex]m\angle K=180^{\circ}-(\angle J+\angle L)[/tex],

[tex]m\angle K=180^{\circ}-(83^{\circ} + 41^{\circ}) = 180^{\circ} - 124^{\circ} = 56^{\circ}.[/tex]

So [tex]m\angle K= 56^{\circ}.[/tex]

Step-by-step explanation:

According to the graph and the data set, we can see that we do indeed have a negative correlation trend. Therefore, options B and D can be eliminated.

Looking at the graph, we can see that we can definitely tell that it is a negative slope and it would be pretty steep. Therefore, the best answer choice would be A. Strong negative.

Answer:

y=1/4x+400

Step-by-step explanation:

Slope=Rise/Run=(300-200)/(-400-(-800))=100/400=1/4

Now we have the slope, making our equation:

y=1/4x+b

We need b, the y-intercept, which we can use any ordered pair to plug in:

200=1/4(-800)+b

200=-200+b

400=b

So the equation that passes through the points (-800, 200) and (-400, 300) is: y=1/4x+400

The equation of line that passes through the points P(-800, 200) and Q(-400, 300) is y = x/4 + 400.

The general equation of straight line is -

y = mx + c

Given is a line that passes through the points P(-800, 200) and

Q(-400, 300).

First we will find the slope of the line -

m = (y₂ - y₁)/(x₂ - x₁)

m = (300 - 200)/(-400 + 800)

m = 100/400

m = 1/4

Now, the line passes through the point Q(-400, 300). Therefore -

300 = (1/4) x (- 400) + c

300 = - 100 + c

c = 400

The final equation of the line will be -

y = x/4 + 400

Therefore, the equation of line that passes through the points P(-800, 200) and Q(-400, 300) is y = x/4 + 400.

The radius of a circle is half the length of the diameter, and the circumference is the perimeter of the circle. However, the circumference is not triple the radius, and the diameter is not triple the length of the radius.

In the context of Mathematics, particularly geometry, the following statements are indeed true about the components of a circle:

However, the statements that the circumference is triple the radius, to find the circumference multiply it by the diameter, and the diameter is triple the length of the radius, are incorrect. The circumference of a circle is calculated as 2πr (two times the radius times Pi), and the diameter is twice the length of the radius, not triple.
