Step-by-step explanation:

The length of the skateboard ramp at the park is 20.4 feet.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let x represent the length of the ramp, hence using trigonometric ratio:

cos(54) = 12/x

x = 12/cos(54)

x = 20.4 feet

The length of the skateboard ramp at the park is 20.4 feet.

The y coordinates of B' is: 8

Step-by-step explanation:

Given

[tex]A = (-5,2)[/tex]

[tex]B =(1,2)[/tex]

[tex]C = (-4,1)[/tex]

[tex]D = (-5,-4)[/tex]

Translation of (x, y) → (x + 6, y – 10)  ---Missing from the question

Required

Determine the y coordinates of B'

We have:

(x, y) → (x + 6, y – 10)  

And

[tex]B =(1,2)[/tex]

So the translation from B to B' is:

[tex]B (1,2) \to B'(1+6,2-10)[/tex]

[tex]B (1,2) \to B'(7,-8)[/tex]

So, we have:

[tex]B' = (7,-8)[/tex]

The y coordinates of B' is: 8

Triangle is missing, so i have attached it.

Answer:

Radius = 10.82

Step-by-step explanation:

From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.

We are given;

AC = 21

BC = 18

Thus;

|AC|² = |AB|² + |BC|²

21² = |AB|² + 18²

|AB|² = 441 - 324

AB = √117

AB = 10.82

Answer:

14.2cm

Step-by-step explanation:

Complete question:

In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.  

Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?  

Find the diagram attached

arc LN= arc  LM + arc MN

First we need to get the arc MN

length of an arc = theta/360 * 2πr

length of arc MN = 75/360 * 2(3.14)(6)

length of arc MN = 0.20833*37.68

length of arc MN = 7.85

Hence;

arc LN = 6.3 + 7.85

arc LN = 14.15cm

Hence the length of arc LN is 14.2cm

y = 5

All sides measure the same So 8y= 40          y = 5

x = 30 degrees

The straight line of 40+40 is a straigth angle of 180 Each angle of equilateral triangle is 60 degrees.So its supplementary is  120.The other 2 angles need to add to 60 (30 each) to sum 180 in a triangle

Answer:

x = 7

y = 25

Step-by-step explanation:

First, we know that x=7 because has the same hypotenuse (the long side) and also has a right angle.

Now, to find out y. The equation for discovering the hypotenuse is:

c = √(a² + b²)

C is the hypotenuse.

A is one of the shorter sides.

B is also one of the shorter sides.

NOTICE: THIS EQUATION ONLY WORKS FOR RIGHT TRIANGLES.

So, now you just need to fill the equation in:

c = √(7² + 24²)

c = √(49 + 576)

c = √(625)

c= 25

So, now we have y, the hypotenuse!

Answer:

$78.58

Step-by-step explanation:

First you divide 235.74 by six to find the individdual   jean price (235.74/6=39.29)   Then you add 39.29+39.29 =  78.58

Answer:

the mean is 6

the median is 6

the mode there is none

the range is 6.

Answer:

There is no mode. (they all appear once)

The lowest number is 3 and the highest is 9, so the range is 6.

The mean is the average, add them all up (30) and divide by the number of data sets (5). The average is 6.

I have to go to dinner so maybe let someone else help with the median? The median is the middle, so you have to order them and find the middle. Hope it helped!
