Answer:

the probability is 0.0067

Step-by-step explanation:

The computation of the probability of receiving no e-mails during an hour is shown below;

Let us assume x be the number of emails received during an hour

Now the probability of receiving no e-mails is

= e^-5 × 5^0÷ 0!

= e^-5 × 1 ÷ 1

= e^-5

= 0.00674

= 0.0067

Hence, the probability is 0.0067

Sec^6x(secxtanx)-sec^4(secxtanx)=sec^5xtan^3x<br> Verify the trigonometric identity

mario62 [17]

I guess you mean

$\sec^6x(\sec x\tan x)-\sec^4x(\sec x\tan x)=\sec^5x\tan^3x$

On the left side, we have a common factor of $\sec^4x(\sec x\tan x)=\sec^5x\tan x$ , so that

$\sec^6x(\sec x\tan x)-\sec^4x(\sec x\tan x)=\sec^5x\tan x(\sec^2x-1)$

Recall that

$\sec^2x=1+\tan^2x$

from which it follows that

$\sec^5x\tan x(\sec^2x-1)=\sec^5x\tan x\tan^2x=\sec^5x\tan^3x$
