Answer:

NK = 42

Step-by-step explanation:

Scale factor of dilating KLMN to form K'L'M'N' = ⅔. This fraction implies there was a reduction of the original shape to form the new image/shape.

NK corresponds to N'K'

N'K' = 28

To get the NK, divide 28 by the scale factor.

28 ÷ ⅔ = 28*³/2 = 42

NK = 42

Answer:

2

Step-by-step explanation:

Rearrange to same form:

2y = -5x + 10

y = -5/2x + 10

ay = -5x + 4

Parallel lines have no intersection and solution, thus a = 2

Answer:

Step-by-step explanation:

For there to be no solution the lines must be parallel and have different y intercepts. To be parallel they must have the same slope.

Solving each for y

y=(10-5x)/2 and y=(4-x)/a

So the slopes are

-5/2 and -1/a, if they are equal

-5/2=-1/a

-5a=-2

a=2/5

Bearing of the flight from Elgin to Canton is:

Answer:

235°

Step-by-step explanation:

Bearing: The angle (in degrees) measured clockwise from north.

The given scenario can be modeled as a triangle.

Given sides of the triangle:

As due north is at a right angle to due west, the angle in the right corner of the triangle is:

⇒ 90° - 44° = 46°

Use the Sine Rule to find angle y marked on the attached diagram (the angle opposite side b).

Sine Rule

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

[tex]\implies \sf \dfrac{\sin 46^{\circ}}{680}=\dfrac{\sin y}{545}[/tex]

[tex]\implies \sf \sin y= \dfrac{545\sin 46^{\circ}}{680}[/tex]

[tex]\implies \sf y= \sin^{-1} \left(\dfrac{545\sin 46^{\circ}}{680}\right)[/tex]

[tex]\implies \sf y=35.20682806...^{\circ}[/tex]

Interior angles of a triangle sum to 180°

⇒ x° + y° + 46° = 180°

⇒ x° + 35.2068...° + 46° = 180°

⇒ x° = 98.79317194...°

Consecutive Interior Angles Theorem

When a straight line intersects two parallel straight lines, the consecutive interior angles formed sum to 180°.  Therefore the angle between due north and side a of the triangle is:

⇒ 180° - 44° = 136°

To find the bearing of the flight from Elgin to Canton, find the angle labelled green on the attached diagram:

[tex]\implies \sf Bearing =136^{\circ}+ 98.79317194...^{\circ}[/tex]

[tex]\implies \sf Bearing = 234.7931719...^{\circ}[/tex]

[tex]\implies \sf Bearing = 235^{\circ}[/tex]

As bearings are usually given as a three-figure bearings, the bearing of the flight from Elgin to Canton is 235°.

Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165​

Step-by-step explanation:  sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .

Z = -1.789

P value = 0.036807

Step-by-step explanation:

Here

H0: p = 0.85 students will have access to the internet at home

Ha: p < 0.85 students will have access to the internet at home

As per the given data, out of 120 sampled students, 95 have access to internet at home

This is 79.17 % of the total number of sampled students.

The Z values is given by

[tex]Z = \frac{p-p'}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

Substituting the given values, we get -

[tex]Z = \frac{0.7917-0.85}{\sqrt{\frac{0.85(1-0.85)}{120} } }\\Z = -1.789[/tex]

The sample proportion of 0.7917 is about -1.789 standard errors below the population proportion given in the null hypothesis.

Considering, result is significant at p < .05, the P-Value is .036807.

The attached parallelogram

Required

Find x and y

Opposite sides are equal

So:

[tex]PQ = SR\ and\ QR = PS[/tex]

This gives:

[tex]2y + 3 = y + 5[/tex] -- (1)

[tex]4x - 3 = 4y + 1[/tex] -- (2)

[tex]2y + 3 = y + 5[/tex]

Collect like terms

[tex]2y - y= 5 - 3[/tex]

[tex]y =2[/tex]

[tex]4x - 3 = 4y + 1[/tex]

Substitute [tex]y =2[/tex]

[tex]4x - 3 = 4 * 2 + 1[/tex]

[tex]4x - 3 = 9[/tex]

Collect like terms

[tex]4x = 3 + 9[/tex]

[tex]4x = 12[/tex]

[tex]x =3[/tex]

By applying Cramer's rule as solution method, the solution of the linear system 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the set (x, y) = (1, 1).

Determinants are constructions studied in linear algebra and related to matrices, one of the most common applications of determinants is the solution of linear equations, whose simplest form is known as the Cramer's rule.

Now we proceed to use this rule to get the solution of the linear system:  

[tex]x = \frac{\left|\begin{array}{cc}5&2\\4&3\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]x = \frac{(5)\cdot (3)-(4)\cdot (2)}{(3)\cdot (3) -(1)\cdot (2)}[/tex]

x = 1

[tex]y = \frac{\left|\begin{array}{cc}3&5\\1&4\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]y = \frac{(3)\cdot (4) - (5)\cdot (1)}{(3)\cdot (3) - (1)\cdot (2)}[/tex]

y = 1

By applying Cramer's rule as solution method, the solution of the linear system 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the set (x, y) = (1, 1).

Answer:

The beam of light is moving along the shoreline at a velocity of approximately 196 kilometers per second.

Step-by-step explanation:

The statement is described geometrically in the image attached below by means of a right triangle. All variables are described below:

[tex]OP[/tex] - Minimum distance between lighthouse and the straight shoreline, in kilometers.

[tex]PP'[/tex] - Distance along the straight shoreline, in kilometers.

[tex]\theta[/tex] - Angle of rotation of the lighthouse, in sexagesimal degrees.

To find the rate of change of distance along the straight shoreline ([tex]\frac{dPP'}{dt}[/tex]), in kilometers per minute, we use the following trigonometric relationship:

[tex]PP' = OP \cdot \tan \theta[/tex] (1)

Then, we differentiate this expression in time:

[tex]\frac{dPP'}{dt} = OP\cdot \dot \theta \cdot \sec^{2}\theta[/tex] (2)

Where [tex]\dot \theta[/tex] is the rate of change of the angle of rotation of the lighthouse, in radians per minute.

The angle at the given instant is calculated by (1): [tex]OP = 5\,km[/tex], [tex]PP' = 1\,km[/tex]

[tex]\theta = \tan^{-1} \left(\frac{PP'}{OP} \right)[/tex]

[tex]\theta \approx 11.310^{\circ}[/tex]

If we know that [tex]\dot \theta = 37.699\,\frac{rad}{min}[/tex], [tex]\theta \approx 11.310^{\circ}[/tex] and [tex]OP = 5\,km[/tex], then the rate of change is:

[tex]\frac{dPP'}{dt} \approx 196,035\,\frac{km}{min}[/tex]

The beam of light is moving along the shoreline at a velocity of approximately 196 kilometers per second.
