Solve n^2+16n=17 by completing the square

larisa [96]

Answer:

305 or N=1

Step-by-step explanation:

N=17, correct?

so what you do first is rewrite the equation:

17^2+16

which will equal:

305

if not and the equation is N^2+16=17

then you have to subtract the 16 first from 17

n^2=1

now you divide or whatever you call it XD

/n^2=/1

so the answer to N=1

20.Solve the inequality. Express your answer in the form of a graph and in interval notation. 3/ − 8 >1

sdas [7]

$\frac{3x}{x-8}>1$

Multiply both-side by (x-8)

3x > 1(x-8)

3x > x - 8

Collect like term

3x- x >-8

2x > -8

Divide both-side by 2

x > -4

This can be represent as;

This can be represented in interval notation as ( -4, ∞)

Only do question 16 50 points Topic: Percentage

leonid [27]

Answer:

329.31

Step-by-step explanation:

The total percentage we have to add is

5+7+1+ .75 =13.75 %

Take the cost of the ticket and multiply by the percentage

289.50 * 13.75%

Change to decimal form

289.50* .1375

39.80625

Rounding to the nearest cent

39.81

Add this to the cost of the ticket

289.50+39.81

329.31

Find the 75th term of the arithmetic sequence 16, 15, 14,

slega [8]

Answer:

$a_{75}=-58$

Step-by-step explanation:

This is an arithmetic sequence:

$a_n=a_1+(n-1)d$

where d is the common difference and n is the index of any given term.

For the given sequence, the common difference is -1:

$15-16=-1\\14-15=-1$

Knowing both the common difference and the first term, you can write the equation for this sequence:

$a_n=16+(n-1)(-1)$

Then you can use that equation to find the 75th term:

$a_{75}=16+(75-1)(-1)\\a_{75}=16+(74)(-1)\\a_{75}=16-74\\a_{75}=-58$
