las tres quintas partes de una bandera son de color rojo, la cuarta parte es azul y el resto blanco ¿ que parte de la bandera es blanco ?​

(a) The expression \( f(x+h) \) is equal to \( 9x + 9h + 4 \).(b) The expression \( f(x+h) - f(x) \) simplifies to \( 9h \).(c) The expression \( h \cdot (f(x+h) - f(x)) \) can be simplified to \( 9h^2 \).

For each of the following expressions for the function \( f(x) = 9x + 4 \), we substitute the given values into the function.

(a) \( f(x+h) \):

Replacing \( x \) with \( (x+h) \) in the function \( f(x) = 9x + 4 \), we have:

\( f(x+h) = 9(x+h) + 4 = 9x + 9h + 4 \)

(b) \( f(x+h) - f(x) \):

Substituting \( f(x+h) \) and \( f(x) \) into the expression, we get:

\( f(x+h) - f(x) = (9x + 9h + 4) - (9x + 4) = 9h \)

(c) \( h \cdot (f(x+h) - f(x)) \):

Multiplying \( h \) with the expression \( f(x+h) - f(x) \), we obtain:

\( h \cdot (f(x+h) - f(x)) = h \cdot 9h = 9h^2 \)

Therefore:

(a) \( f(x+h) = 9x + 9h + 4 \)

(b) \( f(x+h) - f(x) = 9h \)

(c) \( h \cdot (f(x+h) - f(x)) = 9h^2 \)

Answer:

i. Two angles can be vertical and supplementary.

ii. Yes, we can determine the angles.

Step-by-step explanation:

When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to \(180^{o}\).

It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is \(90^{o}\).

Yes, angles that are both vertical supplementary can be determined. They can be  90° each.

Vertical angles are opposite angles where two lines intersect. They are equal. So, angle 1 = angle 2,

A1 = A2 ...{i}

Supplementary angles are those which sum upto form 180. So, angle 1 + angle 2 = 180; i.e.

A1 + A2 = 180 ...{ii} By {i} and {ii} ,

putting i} in ii},

A1 + A1 = 180

Twice A1 = 180

A1 = \(\frac{180}{2}\)

= 90

As,

A1 = A2,

So,

A2 is also 90°

Thus, 90° is the correct answer.

Answer:

x = 6

Step-by-step explanation:

Using this theorem to get the other angles of the triangle.

Angle at the vertex is equal to half of the angle at the intercepted arc

For the arc with angle 170degrees

Angle at the vertex = 1/2 * 170

Angle at the vertex = 85 degrees

For the arc with angle 90degrees

Angle at the vertex = 1/2 * 90

Angle at the vertex = 45 degrees

Taking the sum of the 3 angles and equating to 180

85 + 45 + 12x - 22 = 180

130-22+12x = 180

12x = 180 - 108

12x = 72

x = 72/12

x = 6

Hence the value of x is 6

\(\frac{4}{3}\)

Step-by-step explanation:

Change 4 \(\frac{2}{3}\) into an improper fraction, that is

\(\frac{2}{7}\) × 4 \(\frac{2}{3}\)

Answer:

Step-by-step explanation:

hello :

r+b=7... (*)

3.75r+2.75b=22.25.... (**)

use (*) :  r = 7 - b

put this value in (**) :

3.75(7 - b)+2.75b =  22.25

26.25 -375b +2.75b = 22.5

-375b +2.75b = 22.5 - 26.25

- b = -3.75

so : b  = 3.75

but : r = 7 - b

r = 7 - 3.75

r = 3.25

The length of the given curve between t=0 and t=1 is approximately 13.573 units.

Now, let's move on to the given parametric curve: r ( t ) = ⟨ 6t , t² , 1/9t³ ⟩ , 0 ≤ t ≤ 1. To find the length of this curve, we need to use a formula that involves integrating the length of small line segments along the curve.

The formula we'll use is the arc length formula:

\(L = \int _a^b \sqrt{(dx/dt)^2 + (dy/dt)^2 + (dz/dt)^2 dt}\)

This formula calculates the length of a curve between two points a and b, by integrating the square root of the sum of the squares of the first derivatives of the x, y, and z coordinates with respect to the parameter t.

Using this formula, we can find the length of the given curve as follows:

\(L = \int _0^1 \sqrt{(6)^2 + (2t)^2 + (2/27t^4)^2 dt}\)

\(L = \int _0^1 \sqrt{(36 + 4t^2 + 4/729t^8) dt}\)

\(L = \int_0^1 \sqrt{(2916t^8 + 11664t^6 + 15552t^4 + 6912t^2 + 1296) / 729 dt}\)

This integral is not easy to evaluate directly, but we can simplify it by making a substitution. Let u = 6t² + 6/27t⁶. Then du/dt = 12t + 4/9t⁵, and we can write the integrand as:

\(= > \sqrt{(2916t^8 + 11664t^6 + 15552t^4 + 6912t^2 + 1296) / 729} \\ \\= \sqrt{(u^4 + 3u^2 + 1) / 18t^3}\)

Now we can express the integral in terms of u:

\(L = (1/9) \int _0^6 \sqrt{(u^4 + 3u^2 + 1) / u du}\)

This integral cannot be solved exactly, but we can approximate it numerically using a computer or a calculator. The result is approximately 13.573 units of length.

The most suitable data type for storing annual employee salaries ranging from $25,000 to $700,000 would be option (c) decimal(10,4).

Next, we can consider float and double data types, which can store decimal values with a higher range and precision than integers. However, they can be imprecise and cause rounding errors when used to store currency values, which can be a significant issue in financial calculations.

The most appropriate data type for storing currency values is the decimal data type, which is designed to handle decimal values with high precision and accuracy. The decimal data type can store exact numeric values up to 38 digits, with a user-defined scale (the number of digits to the right of the decimal point).

Therefore, option (c) decimal(10,4) would be the best data type for storing annual employee salaries ranging from $25,000 to $700,000.

mean = \mu = 21.1

standard deviation = \sigma = 5.1

a) P(x ≥ 23 ) = 1 - P(x ≤ 23)

= 1 - P[(x - \mu) / \sigma ≤ (23-21.1) /5.1 ]

Probability= 0.3557

b) n = 50

mu\bar x = \mu = 21.1

σbar x = σ / \\(\sqrt{n}\) = 5.1/ \\(\sqrt{50}\) = 0.7212

P(\bar x ≥ 23) = 1 - P(\bar x ≤ 23 )

= 1 - P[(\bar x - \mu\bar x ) / \sigma\bar x ≤ (23 - 21.1) / 0.7212 ]

= 1 - P(z ≤ 2.63)

= 1 - 0.9957 = 0.0043

Probability = 0.0043

a) The chance of a single student picked at random from all those taking the test scoring 23 or higher is 0.3557.

Step-by-step explanation:

Angles in a  triangle = 180°

 (6x + 20) + (7x - 10) + 105 = 180°

 13x + 10 +105 = 180

  13x + 115 = 180

         -115 = -115      

   13x         = 65

    x = 65/13

     x = 5                  

Any piece of luggage must have a length, width, and height combined that is less than or equal to 150 cm. A traveler requests to take a package with the maximum permitted volume. if the length and width are to be equal, then the dimensions would be 48*96*72

Any piece of luggage must have a length, breadth, and height combined that is 216 cm or less.

L+W+H=216 (because we want the max volume, we may ignore the "less than part" and set them equal) (since we want the max volume, we can ignore the "less than part" and set them equal)

L = W if the length and width are equal.

Let's construct this new equation by swapping L for W.

Arrange H to the left so that H=216-2W when 2W+H = 216

Consequently, what is volume V=L*W*H=W=W2*(216-2W) =216W2-2W3 div./dW=432W-6W?

2\s432W-6W^2=0

72w-w2=0 divided by 6 on both sides.

W = 72 L H = 72 cm

L=2W is the only item that has altered.

Given that L+W+H=216 and that V=L*W*H=2W*W*(216-3W) =432W2-6W, 3W+H=216

864W-18W2 x 3 V prime

Set V prime to 0, solve it by dividing both sides by 18, and you'll get W = 48. dimensions will be

Inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

While we plot the inequality on the graph instead of make a line it will make the shaded region on it.

Given,

Here we have the inequality. y > 3/5x - 2

Now, we need to determine whether the origin is included in the shaded region and whether the shaded region is above or below the line for the graph of the inequality.

In order to solve this, first we have to plot the graph for this inequality.

To plot the graph for the inequality here, we have to use the graphing calculator.

Then we get the graph like the following.

While we looking in the graph we have identified that the origin (0,0) is included in the shaded region.
