Mystery number: The number is less than 190000 and greater than 180000.
Kipish [7]
The answer to it is    
180, 000 <n> 190, 000 
180,000 + 2000 = n = 5000-187, 000 
182,000 = n = 182, 000   
Or,  
 180, 000 <n> 190,000                     
 n + 5000= 187, 000                           n – 2000 = 180, 000 
 n= 187, 000- 5000                             n = 180, 000 + 2000 
 n= 182, 000                                       n= 182, 000

Please help.. I’m stuck on this question
s2008m [1.1K]

Answer: The answer is 1

Step-by-step explanation: The distance between -7 and -3 is 4 then half the distance in between -7 and -3 is going to be -5 because we just clarified that the distance between -7 and -3 is 4 so we did 4/2 and got 2 so we can figure out whats the distance between each point. Now that we figured that out we can determine what value the blue dot is if the value between each point is 2 then we can make out what the rest of the points on the line. If we from -3 to the blue point that would be 1.

Find the derivative of
Gre4nikov [31]

Answer:

<u><em>y' = 1 / sinxcosx</em></u>

Step-by-step explanation:

<u>Given :</u>

y = sinx + cosx / sinx - cosx

<u>Applying quotient rule :</u>

y' = [(sinx - cosx)(cosx - sinx) - (sinx + cosx)(cosx + sinx)] / (sinx -

cosx)²

y' = [sinxcosx - cos²x - sin²x + sinxcosx - (sinxcosx + cos²x + sin²x + sinxcosx)] / (sinx - cosx)²

y' = 2sinxcosx - 2sinxcosx - 2cos²x - 2sin²x / (sinx -cosx)²

y' = -2(sin²x + cos²x) / (sinx - cosx)²

y' = -2 / (sinx - cosx)²

y' = -2 / sin²x - 2sinxcosx + cos²x

y' = -2 / -2sinxcosx

<u><em>y' = 1 / sinxcosx</em></u>  [⇒ Final answer]

Vedmedyk [2.9K]

Answer:

C. 60%

Step-by-step explanation:

<u>Consider 1st row of table</u>

Total Price = P= 22.50

Discount=D=13.50

Percent discount=(D/P) x 100

                           =(13.5/22.5) x 100

                          = 60%

<u>Consider 2nd row of table</u>

Total Price = P= 27

Discount=D=16.20

Percent discount=(D/P) x 100

                           =(16.2/27) x 100

                          = 60%

Now we know discount rate is r=60%
