Life during coronavirus essay in 250 words right answer plz​

Answer»

Answer:

The world is grappling with an invisible, deadly enemy, trying to understand how to live with the THREAT posed by a virus. For some WRITERS, the only way forward is to put pen to PAPER, trying to conceptualize and document what it feels like to continue living as countries are under lockdown and regular life seems to have ground to a halt.

So as the coronavirus pandemic has stretched around the world, it’s sparked a crop of diary entries and essays that describe how life has changed. Novelists, critics, artists, and journalists have put words to the feelings many are experiencing. The result is a first draft of how we’ll someday REMEMBER this time, filled with uncertainty and pain and fear as well as small moments of HOPE and humanity.

Value of (cos A +cosB/sinA-sinB)^2015 +(sinA+sinB/cosA-cosB)^2015=?​

Answer»

Given: The trigonometric term

            (cos A + cosB / sinA - sinB)^2015 +(sinA + sinB / cosA - cosB)^2015

To find: The value of the given expression?

SOLUTION:

  • Now we have given the term as:

          (cos A + cosB / sinA - sinB)^2015 +(sinA + sinB / cosA - cosB)^2015

  • Now we know the formulas :

          cos A + cosB = 2 cos(a+b/2) cos (a-b/2)

          sinA - sinB = 2 cos(a+b/2) sin(a-b/2)

          sinA + sinB = 2 sin(a+b/2) cos(a-b/2)

          cosA - cosB =  -2 sin(a+b/2) sin(a-b/2)

  • Consider first term:

          (cos A + cosB / sinA - sinB)^2015

  • So putting the values in the expression, we GET:

          (2 cos(a+b/2) cos (a-b/2))^2015 / (2 cos(a+b/2) sin(a-b/2))^2015

  • Cancelling common terms, we get:

          (cos (a-b/2))^2015 / (sin(a-b/2))^2015

          (cot (a-b/2))^2015

  • Consider second term:

          (sinA + sinB / cosA - cosB)^2015

  • So putting the values in the expression, we get:

          (2 sin(a+b/2) cos(a-b/2))^2015 / (-2 sin(a+b/2) sin(a-b/2))^2015

  • Cancelling common terms, we get:

          (cos (a-b/2))^2015 / (sin(a-b/2))^2015

          (cot (a-b/2))^2015

  • Not TAKING them together, we get:

          (cot (a-b/2))^2015 - (cot (a-b/2))^2015

          0

Answer:

                So the answer of the given expression is 0.

A car travels for 6 hours at different speeds. For the first hour, it travels at 60 m/s, for the next 2hours at 50 m/s and for the remaining time at y m/s. If the average speed for the entire journey is 52 m/s, find the value of y.​

Answer»

Answer:

y  =  50⅔  ≈  50.6667

[ So the SPEED is  50⅔ m/s  =  182.4 km/hr ]

Step-by-step explanation:

Let a be the distance travelled in the first hour.

Let b be the distance travelled in the second hour.

Let c be the distance travelled in the third hour.

Since

  • distance = speed × time

the given information says

  • a  =  60 m/s × 1 hr  =  60  m hr/s     (a strange unit, but there's no need to convert to m or km since the units don't matter; we just need to always use the same units)
  • b  =  50 m/s × 2 hr  =  100 m hr/s
  • c  =  y m/s  × 3 hr  =  3Y m hr/s
  • a + b + c  =  52 m/s × 6 hr  =  312 m hr/s

This gives

60 + 100 + 3y = 312   ⇒   y = (312 - 160) / 3  = 152 / 3  =  50⅔

Hope this HELPS.

use euclied's dividion lemma to show that the cube of any positive integer is of the from 9m,9m+1 or 9m+8.​

Answer»

Step-by-step explanation:

To prove that,

The cube of any positive integer is of the form 9m, 9m+1 or 9m+8.

First of all,

LET's ASSUME that a be any positive integer and b = 3.

Therefore, we can write,

=> a = 3q + r,

Where q ≥ 0 and 0 ≤ r < 3.

Therefore, we have possible values of r = 0,1,2

Now, we know that,

Every number can be represented as these three forms.

Therefore, we have 3 cases.

CASE I: When a = 3q, 

=> a^3 = (3q)^3

=> a^3 = 27q^3

=> a^3 = 9(3q^3)

=> a^3 = 9m

Where, m is an integer such that m = 3q^3.

Case II: When a = 3q + 1,

=> a^ 3 = (3q +1)^ 3 

=>a^3 = 27q^ 3 + 27q ^2 + 9q + 1 

=> a^ 3 = 9(3q^ 3 + 3q ^2 + q) + 1

=> a ^3 = 9m + 1 

Where, m is an integer such that m = (3q ^3 + 3q^ 2+ q). 

Case III: When a = 3q + 2,

=> a^3 = (3q +2)^ 3 

=> a^ 3 = 27q^ 3 + 54q ^2 + 36q + 8 

=> a^ 3 = 9(3q ^3 + 6q ^2 + 4q) + 8

=> a^ 3 = 9m + 8

Where, m is an integer such that m = (3q^ 3 + 6q^ 2+ 4q). 

Hence, the cube of any positive integer is of the form 9m, 9m + 1, or 9m + 8.

Thus, Proved.

Prove that:-cotA - tanA= 2cos^2 A- 1÷ sinA cosA​

Answer»

Step-by-step explanation:

before i solve you must know that cotA=cosA/sinA

and TANA=sina/cosA

hence cotA - tanA= cosA/sinA - sinA/cosA

taking LCM

=cos^ 2 A - sin^2 A/sinAcosA

but sin^2 A + cos^2 A=1

which implies than sin^2 A = 1 - cos^2 A

putting this value in ORIGINAL EQUATION

we get, cotA - tanA = cos^2 A -1 + cos^2 A/sinAcosA

= 2cos^2A - 1/sinAcosA as required

I hope this helps!!
