Brainliest pls??

Answer:

The song fully played 225 times.

Step-by-step explanation:

Really? What a question.

Between 10:55 pm and 9:50 am, 13 hours and 5 minutes elapse.

For us to calculate how many times the song played, we need to convert them to the same units, i.e. seconds.

3 minutes and 29 seconds = 209 seconds

13 hours and 5 minutes = 47100 seconds

If 47100 seconds elapsed and the song was playing on repeat the whole time, we can calculate how many times it played by:

47100/209 = 225.36 (approximation to the nearest hundredth)

So, the song fully played 225 times.

Use the laws of Sines and law of cosines to find missing dimensions​
Andrei [34K]

Answer:

A) ERROR

B) ∠C = 26°

Step-by-step explanation:

Houston, We have a problem!!! too much information

If we had a legit triangle, the law of sines would hold

19/sin138 = 8/sin20

  28.395 = 23.390

as this is NOT an equality, the triangle does not exist as described.

IF it did, we'd get different results depending on which set we used

∠F = 180 - 138 - 20 = 22°

Law of sines

19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>

or

8/sin20 =  DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>

If we attempt to use Law of cosines

DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>

so really none is correct because we attempt to use trig calculations to a non-triangle.

12) AC² = 15² + 19² - 2(15)(19)cos120

      AC = 29.51270...

29.51270 / sin120 = 15/sinC

C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>

Examine the following graph, where P(x) is the preimage and I(x) is the image after a transformation.
Arisa [49]

Answer:

the 4th answer I(x) = P(x-4)

Step-by-step explanation:

the first 2 options are out, because just adding values to the functional result values changes the y value, and the curve is pushed up or down. but not to the side.

just imagine

I(x) = P(x-4) means that the function value of previously at x-4 happens now at x. 4 units "later" (or more to the right).

"x+4" would make the functional value at previously x+4 happen now at x. so, everything would shift to the left (happen "earlier").

therefore, the 4th answer option is correct.

Find the 137th odd number.
KIM [24]

The first odd number is 1. The next is 2 more than the previous one.

It's an arithmetic sequence.

The general term of an arithmetic sequence:

a_n=a_1+(n-1)d

a_n - n-th term

a_1 - first term

d - common difference.

We have

a_1=1,\ d=2,\ n=137

Substitute:

a_{137}=1+(137-1)(2)=1+(136)(2)=1+272=273

<h3>Answer: 137th odd number is equal 273.</h3>
