Answer:

The ratio of any two corresponding lengths in two similar geometric figures.

Step-by-step explanation:

You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.

If you divide the length of DE by the length of AB:

a^2/a =a.

You get a scale factor of “a”

Answer:

After 60 minutes, Sam is 6 meters from the dock

Step-by-step explanation:

I looked at the number line and met up where 60 minutes was.

After 6 minutes, Sam is 60 meters from the dock

Correct option is D.

A straight line is an infinitely long line with no curves. A straight line can also be formed between two points, but the ends will be infinite. A straight line is a figure formed by connecting two points A (x1, y1) and B (x2, y2)  with the shortest distance and extending both ends to infinity.

General formula for a straight line:

The general equation for straight lines is given as ax + by + c = 0.

a, b, c are constants and

x,y are variables.

Slope is -a/b  

Given,

Graph of Distance to time is represented by an straight line

By the graph,

Line crosses from (0,20) and (3,40)

Equation of the line

y - y₁ = ((y₂ - y₁)/(x₂ - x₁))(x-x₁)

y - 20 = ((40 - 20)/(3 - 0))(x-0)

y - 20 = (20/3)(x)

y - 20 = 20x/3

y = 20x/3 + 20

Input x = 6

y = 20(6)/3 + 20

y = 120/3 + 20

y = 40 + 20

y = 60

When time = 6 minutes, distance between Sam and the dock is 60 meters.

Hence, Sam is 60 meters away from the dock after 6 minutes

Answer: 59.04

Step-by-step explanation:

tan 16= x/200

tan16/1=x/200  

200 tan 16=x  

x=57.349077...

x=57.349077...

Add 1.69, the distance from the ground to her eye:

57.349077...+1.69= 59.039077...

≈   The skyscraper is 59.04 meters tall.

You can use right triangles to get the height of the skyscraper.

The height of the skyscraper is 59.04 meters approximately.

You look straight parallel to ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal to the point where you stopped your head is called angle of elevation. See the figure where angle DCE is the angle when Penelope saw the skyscraper. It  is measured from the horizontal line DC.

Remember that we assume that building is vertical to the ground. This means, there is 90° formation.

Since the distance from the base of the building is given and the angle of elevation is given, we have enough data to construct a specific right triangle where the vertical line opposite to the angle of elevation is of the measure of the height of the building.

And then we can use tangent ratio which relates perpendicular and base to the considered angle.

Remember that trigonometric ratios are defined for right triangles only(those triangles who have one of the angle as of 90 degrees).

See the diagram attached below, where the length AE is the building's height. AD is same as CB which is height of Penelope(a person who is watching the top of that given skyscraper).

For the right angle triangle EDC, and for the angle considered ∠ECD, we have the perpendicular as side opposite to the angle ∠ECD which is ED and the base is DC. Thus, the tangent ratio of ∠ECD is given by

[tex]tan(\angle ECD) = \dfrac{Perpendicular \: to \: \angle ECD}{Base \: to \: \angle ECD } = \dfrac{ED}{DC} = \dfrac{h - 1.69}{200}\\tan(16^\circ) = \dfrac{h - 1.69}{200}\\[/tex]

DC = AB and DA = CB because of ABCD being a rectangle because of building and person both standing vertical to the ground and the line DC being parallel to the ground, thus all angles being right angle(of 90 degrees).

From the calculator, the value of tan(16°) is approx 0.2867

Thus, putting this value in the obtained equation, we get:

[tex]tan(16^\circ) = \dfrac{h - 1.69}{200}\\0.2867 = \dfrac{h-1.69}{200}\\\\0.2867 \times 200 = h - 1.69 \\57.35 + 1.69 = h\\h = 59.04 \: \rm meters[/tex]

Thus, the height of the specified skyscraper is  approx 59.04 meters.

Answer:

Step-by-step explanation:

a) We have 15! as the product of 1 to 15 natural numbers.  Since 17 is prime there will be no factor common to these

By actual division we find

15! (mod 17) =16

From this we deduce

even 16! mod 17 = 16 = -1

According to Wilson theorem

(17-1)! = -1 mod 17

Thus verified 17 is prime

Hence 15! (mod 17) =-1=16

-----------------------

b) 2(26!) is divided by 29

Since 29 is prime

(29-1)! = -1 mod 29

28! = -1 mod 29 = 28

When divided this gives 25 as remainder

Answer:

A. 2x

Step-by-step explanation:

First let's correct the problem.

Question:

[tex]14x^2-12x[/tex] is the binomial we are solving

Now, let's solve this.

We see that we have one term to the 2nd degree (shown by the exponent) and one to base degree. Therefore, the answer cannot be B or C since you cannot factor into a negative exponent.

So we now have either A. 2x or D. 4x

Let's try both of these.

Factoring out with 2x we get:

[tex]2x(7x-6)[/tex], which is perfectly fine!

Factoring out with 4x we get:

[tex]4x(3.5x-3)[/tex]

Therefore, it must be A. 2x

Alternatively, we know the factors of 14 are 1,2,7, and 14. The factors of 12 are 1,2,3,4,6, and 12. The only factor shared here is A. 2

Step-by-step explanation:

Hey there!

The Pythagorean identity is: sin²(theta) + cos²(theta) = 1.

So, For finding sin (theta);

Take cos (theta) right side.

sin²(theta) = 1-cos²(theta)

Now, take square on right side from.

sin (theta) = √[1-cos²(theta)] {square changes into square root}

Therefore, sin (theta) = √[1-cos²(theta)].

2.16=216/100=54/25

check your statement.

[tex]\frac{54}{25 }[/tex] is the rational number for the decimal 2.16

A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero.

According to the given question.

We have a number 2.16

To convert the above in rational number, we convert the given number  in [tex]\frac{x}{y}[/tex] form, where x and y are positive integers.

We read 2.16 as " 2 and sixteen hundredths".

Therefore, 2.16 can be written as [tex]2\frac{16}{100}[/tex].

Now we will simplify [tex]2\frac{16}{100}[/tex].

⇒ [tex]2\frac{16}{100} =2\frac{4}{25}[/tex]

⇒ [tex]2\frac{16}{100} =\frac{54}{25}[/tex]

Hence,  [tex]\frac{54}{25 }[/tex] is the rational number for the decimal 2.16
