Answer:

28

Step-by-step explanation:

sin=\frac{opp}{hyp}

cos = \frac{adj}{hyp}

cos^{-1}\left(\frac{45}{51}\right)

which is 28.07 degree

sin\left(28.07\right)=\frac{x}{51}

x= 23.99

23.99+4=h=28

Nora had already read 30% of the book before her teacher assigned it to the class. She is choosing between two options to finish
guapka [62]

Answer:

Let p represent the # of pages in the book.  Then, Nora has already read 0.30p pages and has 0.70p pages left to read.

If she reads 25% pages/night, that means reading 0.25(0.70)p pages per night, or 17.5 pages/night.  If 28% p/n, that means 0.28(0.70)p pages/night, or 19.6p pages/night.

How many nights will it take Nora to finish the book if she reads 25% of 7/10 of the book per night?  Without any calculations, we can answer this by "4 nights, since she reads 1/4 of the unread portion of the book per night."

If she reads 28% of 7/10 of the book per night, that will require fewer nights:

First night:  28%

Second night:  28%  

Third night:  28%

 Total:  3(28%) = 84%

This leaves 16% to read on the final night.

This is one interpretation of what I think is a poorly worded question.

The author of this question might have meant reading 25% of the remaining unread pages per night, which leads to a different answer.

Can you find the equation in standard form when given 3 or more orders pairs on a parabola
Anettt [7]

Answer:

Yes, you can

Step-by-step explanation:

The standard form of the equation of a parabola is y=ax^2+bx+c

When given three points, you substitute each point into the equation to obtain 3 simultaneous linear equations.

You then solve the three equations simultaneously to find the values of the constants a,b, and c.

You then substitute these constants into y=ax^2+bx+c
