Answer:

A robot can complete 8 tasks in hour = $\frac{5}{6}$

A robot can complete 1 task in hour = $\frac{\frac{5}{6}}{8}$

A robot can complete 1 task in hour = $\frac{5}{48}$

So, it take $\frac{5}{48}$ hours the robot to complete the task

A robot can complete tasks in $\frac{5}{6}$ hour = 8

A robot can complete tasks in 1 hour = $\frac{8}{\frac{5}{6}}$

= $9.6$

So, the robot complete 9 tasks in one hour.

5/6 hour = 5/6 × 60 = 300/6 = 50 minutes

8 tasks in 50 minutes
1 task = 50/8 = 6 1/4 minutes

a. robot completes task in 6 1/4 minutes

b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6

robot can complete 9 tasks in one hour

(sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x

As

$\tan x=\dfrac{\sin x}{\cos x}$
$\cot x=\dfrac{\cos x}{\sin x}$

we have

$\sin x(\tan x\cos x-\cot x\cos x)=\sin x\left(\sin x-\dfrac{\cos^2x}{\sin x}\right)=\sin^2x-\cos^2x$

Recalling that $\cos2x=\cos^2x-\sin^2x$ , we end up with

$-\cos2x=1-2\cos2x$
$1=\cos2x$
$\implies2x=2n\pi$

(where $n$ is any integer)

$\implies x=n\pi$
