The measure of side length x in the right triangle is approximately 13.0.

The figure in the image is a right triangle, having one of interior angle at 90 degrees.

Let;

Angle θ = 30 degree

Adjacent to angle θ  = x

Hypotenuse = 15

To solve for the missing side length x, we use the trigonometric ratio.

Note that: cosine = adjacent / hypotenuse

Hence:

cosθ = adjacent / hypotenuse

Plug in the given values and solve for x.

cos( 30° ) = x / 15

Cross multiplying, we get:

x  = cos( 30° ) × 15

x = 13.0

Therefore, the value of x is 13.0.

Work Shown:

Segments AB, BC, CD, DA, and DN are all the same length (4 units)

The semicircle has area of

A = (1/2)*pi*(radius)^2

A = 0.5*pi*2^2

A = 2pi

The square has area of

B = (side length)^2

B = 4^2

B = 16

The trapezoid has area of

C = (height)*(base1+base2)/2

C = (DN)*(CD+MK)/2

C = (4)*(4+8)/2

C = 24

Add up the results of A, B and C to get the total area

A+B+C = 2pi+16+24 = 2pi+40

The total area is 2pi+40 square mm

The area of the figure will be 2π + 40 mm². Then the correct option is C.

The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.

The figure is made by semicircle, square, and trapezium. Then the area is given as,

A = Area of a semicircle + Area of square + Area of trapezium

A = (π / 2) x r² + (AB)² + 1/2 x (CD + MK) x DN

A = (π / 2) x 2² + (2 x 2)² + 1/2 x (4 + 8) x 4

A = 2π + 16 + 24

A = 2π + 40 mm²

The area of the figure will be 2π + 40 mm². Then the correct option is C.

Answer:

The discriminant is negative.

Step-by-step explanation:

Since the parabola does not hit the x-axis, there are no x-intercepts to the graph or real roots of the equation.  This means the square root portion of the quadratic formula failed to produce any real solutions, because you ended up trying to take the square root of a negative number.

When this happens, the equation will have two imaginary/complex solutions.

Given that three charges (-25 nC, 79.1nC, and −55.9nC) are placed at three of the four corners of a square with sides of length 22.2 cm. We need to determine the value of the electric potential (in V) at the empty comer if the positive charge is placed in the opposite corner.

The formula for the electric potential at a point in space is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) + ….. ]where;k = Coulomb's constant (8.99 × 10^9 Nm²/C²)q1, q2, q3,…. are the charges at the cornersr1, r2, r3,…. are the distances from the corner to the point whose potential is being calculated Now we can calculate the electric potential at the empty corner as follows;The three charges can be represented as shown below:Charges at corners of a square

The distance from any corner to the opposite corner (where the positive charge is placed) is given by d = √[ (22.2 cm)² + (22.2 cm)² ] = 31.4 cmTherefore, the electric potential at the empty corner is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) ]Here, q1 = -25 nC, q2 = -55.9 nC, q3 = 79.1 nC, r1 = r2 = r3 = d = 31.4 cm = 0.314 mPlugging in the values we get;V = 8.99 × 10^9 [ (-25 × 10^-9 / 0.314) + (-55.9 × 10^-9 / 0.314) + (79.1 × 10^-9 / 0.314) ]= 8.99 × 10^9 [ -0.0795 - 0.1783 + 0.252 ]= 8.99 × 10^9 × 0.0052= 46.8 VTherefore, the value of the electric potential at the empty comer if the positive charge is placed in the opposite comer is 46.8 V.

If Jason paid $88.50 in tax on a table that cost $1,180, the tax rate (sales tax) is 7.5%.

The tax rate is the percentage that is paid in tax.

For sales tax (consumption tax), the tax rate is fixed, making it a proportional tax rate system.

For income tax, the tax rate follows a progressive tax rate system.  The percentage of tax increases as the taxable income increases.

Some tax rates are said to be retrogressive as the rates reduce with increased taxable income.

The amount of sales tax on the table = $88.50

The cost of the table = $1,180

Tax rate = 7.5% ($88.50/$1,180 x 100)

To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.

Looking at the histograms described:

The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.

The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.

The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.

The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.

Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

The bottom width and depth of the trapezoidal channel are 2.25 m and 1.67 m, respectively.

In Windsor area of New South Wales, flood flow needs to be drained from a small locality at a rate of 120 m³/s in uniform flow using an open channel (n=0.018) Given the bottom slope as 0.0013 calculate the dimensions of the best cross section if the shape of the channel is (a) circular of diameter D and (b) trapezoidal of bottom width b.

(a) Circular channel:

For a circular channel, the best hydraulic section can be achieved by using the formula,

Q = (1 / n) x (A / P)2 / 3 x S0.5

where Q is the discharge; A is the area of the flow section; P is the wetted perimeter, S is the slope of the channel; and n is the roughness coefficient of the channel.

Assuming that the channel is flowing at full capacity, the depth of flow can be calculated using the following formula,

Q = (1 / n) x (π / 4) x D2 / 2 x D1 / 2 x S0.5

where D is the diameter of the channel; S is the slope of the channel; and n is the roughness coefficient of the channel.

Solving for D,

D = (8Q / πnD12S0.5)

For the given values of Q, n, and S,

D = (8 × 120 / π × 0.018 × 0.00132 × 120.5)

D = 1.98 m

Therefore, the diameter of the circular channel is 1.98 m.

(b) Trapezoidal channel:

For a trapezoidal channel, the best hydraulic section can be achieved by using the formula,

Q = (1 / n) x (A / P)2 / 3 x S0.5

where Q is the discharge; A is the area of the flow section; P is the wetted perimeter, S is the slope of the channel; and n is the roughness coefficient of the channel.

Assuming that the channel is flowing at full capacity, the depth of flow can be calculated using the following formula,

Q = (1 / n) x ((b + y) / 2) y / ((b / 2)2 + y2)0.5 x ((b / 2)2 + y2)0.5 x S0.5

where b is the bottom width of the channel; y is the depth of flow in the channel; S is the slope of the channel; and n is the roughness coefficient of the channel.

Rewriting the equation,

120 = (1 / 0.018) x ((b + y) / 2) y / ((b / 2)2 + y2)0.5 x ((b / 2)2 + y2)0.5 x (0.0013)0.5

Simplifying the equation,

658.5366 = (b + y) y / ((b / 2)2 + y2)0.5 x ((b / 2)2 + y2)0.5

Squaring both sides,

433407.09 = (b + y)2 y2 / ((b / 2)2 + y2) x ((b / 2)2 + y2)

Multiplying both sides by ((b / 2)2 + y2),

433407.09 ((b / 2)2 + y2) = (b + y)2 y2 x ((b / 2)2 + y2)

Simplifying the equation,

216703.545 = b2 y3 / 4 + b y4 / 2 + y5 / 4

Solving the above equation by using trial and error, the bottom width and depth of the trapezoidal channel are 2.25 m and 1.67 m, respectively.

The inequality -1/2x ≥ 4 on a number line by placing an open circle at -8 and shading the region to the left of -8. The number line is

<-----o==============>

     -8

To represent the solution set for the inequality -1/2x ≥ 4 on a number line, we first need to find the values of x that satisfy the inequality. To do this, we can start by multiplying both sides of the inequality by -2, which will change the direction of the inequality:

-1/2x ≥ 4

-2(-1/2x) ≤ 4(-2)

x ≤ -8

This tells us that any value of x that is less than or equal to -8 will satisfy the inequality. We can represent this set of values on a number line by shading the region to the left of -8, since any value less than or equal to -8 will also be less than or equal to -8.

Therefore, we can represent the solution set for the inequality -1/2x ≥ 4 on a number line by placing an open circle at -8 (since the inequality is not inclusive of -8) and shading the region to the left of -8. The resulting number line is shown below:

<-----o==============>

     -8

The open circle at -8 indicates that x cannot be equal to -8, since the inequality is not inclusive of -8. The shaded region to the left of -8 indicates that any value of x that is less than or equal to -8 will satisfy the inequality.

Given:

The equation of parallel line is:

\(3x-2y=5\)

The required line passing through the midpoint of the line segment joining the points (-4,2) and (2,4).​

To find:

The equation of required line.

Solution:

Midpoint of  line segment joining the points (-4,2) and (2,4) is:

\(Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)\)

\(Midpoint=\left(\dfrac{-4+2}{2},\dfrac{2+4}{2}\right)\)

\(Midpoint=\left(\dfrac{-2}{2},\dfrac{6}{2}\right)\)

\(Midpoint=\left(-1,3\right)\)

It means the required line passes through the point (-1,3).

The slope of line \(Ax+By=C\) is:

\(m=\dfrac{-A}{B}\)

The given equation is:

\(3x-2y=5\)

Here, A=3 and B=-2. So, the slope of the line is:

\(m=\dfrac{-3}{-2}\)

\(m=1.5\)

Slope of parallel lines are same. So, the slope of the required line is 1.5.

The required line passes through the point (-1,3) with slope 1.5. So, the equation of the line is:

\(y-y_1=m(x-x_1)\)

\(y-3=1.5(x-(-1))\)

\(y-3=1.5(x+1)\)

\(y-3=1.5x+1.5\)

Adding 3 on both sides, we get

\(y=1.5x+1.5+3\)

\(y=1.5x+4.5\)

Therefore, the equation of the required line is \(y=1.5x+4.5\).
