A 10 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building. How far up the building do

Anarel [89]

The answer is 5sqrt2 or 7.07
Since you have one 45 degree angle the other angle is also 45 degrees. This gives you a right isosceles triangle.
This can be solved using Pythagorean theorem or trig ratios.
a^2+a^2= 100
2a^2 = 100
a^2=50
a= sqrt 50
a=5sqrt2

Consider a set of one-dimensional points: 6, 12, 18, 24, 30, 42, 48.

Vinvika [58]

Answer:

1) With initial centroids 10-40, final clusters are

first cluster (6,12,18,24,30)

second cluster (42,48)

And the Sum of Squared Errors (SSE) for the clustering result is 378

2) With initial centroids 10-20, final clusters are

first cluster (6,12,18,24)

second cluster (30,42,48)

And the Sum of Squared Errors (SSE) for the clustering result is 348

Step-by-step explanation:

K-means works as follows

the points will be clustered according to their distance to the centroids.
Then centroids are updated as the cluster means.
This process continues until clusters doesn't change anymore

1) <u><em>initial centroids</em></u> 10-40

first cluster (6,12,18,24) mean:15

second cluster (30,42,48) mean:40

<u><em>new centroids</em></u> 15-40

first cluster (6,12,18,24,30) mean:18

second cluster (42,48) mean:45

<u><em>final centroids</em></u> 18-45

first cluster (6,12,18,24,30) mean:18

second cluster (42,48) mean:45

Sum of Squared errors = $(18-6)^{2}$ + $(18-12)^{2}$ + $(18-18)^{2}$ + $(18-24)^{2}$ + $(18-30)^{2}$ + $(45-42)^{2}$ + $(45-48)^{2}$ =378

2)<u><em>initial centroids</em></u> 10-20

first cluster (6,12) mean:9

second cluster (18,24,30,42,48) mean:32.4

<u><em>new centroids</em></u> 9-32.4

first cluster (6,12,18) mean:12

second cluster (24,30,42,48) mean:36

<u><em>new centroids</em></u> 12-36

first cluster (6,12,18,24) mean:15

second cluster (30,42,48) mean:40

<u><em>final centroids</em></u> 15-40

first cluster (6,12,18,24) mean:15

second cluster (30,42,48) mean:40

Sum of Squared errors = $(15-6)^{2}$ + $(15-12)^{2}$ + $(15-18)^{2}$ + $(15-24)^{2}$ + $(40-30)^{2}$ + $(40-42)^{2}$ + $(40-48)^{2}$ =348

Hi looking for help ASAP ASAP ASAP ASAP

AURORKA [14]

Answer:

see explanation

Step-by-step explanation:

A translation of 6 units to the right, means adding 6 to the x- coordinate.

J (- 4, 5 ) → J' (- 4 + 6, 5 ) → J' (2, 5 )

K (- 2, 1 ) → K' (- 2 + 6, 1 ) → K' (4, 1 )

L (- 4, 2 ) → L' (- 4 + 6, 2 ) → L' (2, 2 )
