Answer:

([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)

Step-by-step explanation:

Using the factorising method, difference of 2 squares

a² - b² = (a - b)(a + b) , then

5n² - 16

= ([tex]\sqrt{5}[/tex] n )² - 4²

= ([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)

Answer:

21.13 m

Step-by-step explanation:

Height of the string, (Hyoptenuse) = 50 m

The kite makes an angle of elevation with the ground of 25°.

We need to find how high is the kite above the ground. Let it is h. We can find it using trigonometry as follows :

[tex]\sin\theta=\dfrac{P}{H}\\\\h=H\sin\theta\\\\h=50\times \sin(25)\\\\H=21.13\ m[/tex]

So, the required height is 21.13 m.

Line segment TU is parallel to line segment RS because 32/36 = 40/45.

According to the "Side Splitter" Theorem, a line that crosses two sides of a triangle and runs parallel to its third side proportionally divides those two sides.

A line will divide two sides of a triangle proportionally if it runs parallel to one of the sides and intersects the other two.

Given

It is evident from the presented figure that QT=32, TR=36, QU=40, and US=45.

The opposite of the side splitter theorem asserts that a line is parallel to a third side if it divides two sides proportionally.

TU separates the two sides by a factor of in

QT/TR = 32/36 = 8/9

QU/US = 40/45 = 8/9

QT/TR = QU/US

It implies that the line TU divides the two sides equally.

Line segment TU is parallel to line segment RS using the reverse of the side splitter theorem because

32/36 = 40/45

Hence option 1 is correct.

Step-by-step explanation:

√(20+5²)=√{20+25}=√45=3√5

Answer:

D. y = -1/2x + 18.5

Step-by-step explanation:

First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.

(1, 18) & (6, 15.5)

Plug in these values:

(15.5 - 18) / (6 - 1)

Simplify the parentheses.

= (-2.5) / (5)

Simplify the fraction.

-2.5/5

= -1/2

This is your slope.

Now plug this into the standard slope-intercept equation: y = mx + b

y = -1/2x + b

b is the y-intercept, or the value of y when x = 0.

To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 18). Plug in the x and y values into the x and y of the standard equation.

18 = -1/2(1) + b

To find b, multiply the slope and the input of x (1)

18 = -1/2 + b

Now, add 1/2 to both sides to isolate b.

18.5 = b

Plug this into your standard equation.

y = -1/2x + 18.5

This is your equation.

Answer:

Step-by-step explanation:

use the law of Cosines so that you can solve a SSS triangle

Cos(C) = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex]  / 2ab

c is the side of 24 for our triangle and angle C is the top one in the picture.

C = arcCos ( [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex]  / 2ab )

C = arcCos ( -32 / 480 )

C = 93.82255373 °

the angles at the top are each half of that or 46.91127 °

let's solve another angle for the big triangle now let's go for the one on the left and call it A

Cos(A) = [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex]  / 2bc   where a = 20

A = arcCos( [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex]  / 2bc)

A = arcCos( [tex]24^{2}[/tex] + [tex]12^{2}[/tex] - [tex]20^{2}[/tex] / 2*12*24

A = arcCos(320 / 576)

A = 56.2510 °

then angle B is  180 =93.823 + 56.251 + B

29.926 ° = B

so now we know all 3 angles.. seems like a lot of work , huh  :D

for the triangle with the question mark we now know two angles and the Hyp, so let's use Law of Sines to find that last side  :)

Sin(A)/a = Sin(B) /b  where A can be the angle at the top and B can be the angle at the base. which we have to find still  :/  

it's 180 = 46.9112 + 29.926 + B

103.162 = B

Sin(46.91127 ) / a = Sin(103.162) /20

Sin(46.91127 ) * 20 / Sin(103.162) = a

14.99998 = a    I feel confident this is supposed to be 15 and I have a tiny bit of rounding error..

∠A=26º

∠B=137º

∠C=17º

Step-by-step explanation:

We can use the Law of Cosines because we have all 3 side lengths.

cosA = [tex]b^2+c^2-a^2/2bc[/tex]

cosA=28^2+12^2-18^2 / 2(28)(12)

cosA=604/672

cos-1(604/672

angle A ≈ 26º

cosB =  [tex]c^2+a^2-b^2/2ca[/tex]

cosB=-316/432

cos-1(-316/432

angle B ≈ 137º

26+137=163

Step-by-step explanation:

Given :

Length = 2 * width

If :

length = l

Width, w

l = 2w

Perimeter, P of rectangle :

P = 2(l + w)

P = 2(2w + w)

w = 300/6

w = 50

l = 2w

l = 2(50)

Answer:

BE=15

Step-by-step explanation:

Since E is the center, BE=2x+1

And AC is 6x-12 with E being a midpoint.

Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that

you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE

6x-12=4x+2

BD=AC

6x-4x-12=2

2x=2+12

2x=14

x=7

BE= 2x+1

2(7)=14+1=15

Answer:

Step-by-step explanation:

the perimeter of the semi-circle would be the diameter plus the circumference of half of the circle.  

They want to know the perimeter of a square using the diameter of the sem-circle as ONE side, so the perimeter of the square would be 4 times the ONE side.

We should recall:

diameter = 2 times the radius     circumference of a cirlce = 2π r

How do we find the diameter of the of the semi circle?

The perimeter of the semi circle is given as 108 cm

Perimeter of the semicirle =    2r + π r         diameter plus semi circumference

                                  108   =   r ( 2 + π)           factor out the r and solve for r

                     108 / (2 + π)   =   r                       divide both sides by ( 2 + r)

Now we know r, the perimeter of the squqre is 4 times 2r  or  8r

           perimeter of square = 8  [ 108 / (2 + π) ]               π  I used 3.14

                                             =  864 / 5.14

                                             =   168.1 cm       I got rounded to nearest tenth    

When I re-checked by work I found a few math,  logic and calculation errors.  Please re-check my answer for any more mistakes.
