How many solutions does the equation sin(4x)= 3/4?

MAVERICK [17]

$sin(4x)= \dfrac{3}{4}$

$4x=sin^-^1( \dfrac{3}{4}), \pi -sin^-^1( \dfrac{3}{4})$

<span>Since sin is a periodic function, add the periodicity.
</span>
$4x=2\pi n+sin^-^1 ( \dfrac{3}{4} ) ,nEZ 

$

$4x=2\pi n-sin^-^1 ( \dfrac{3}{4} ) ,nEZ$

$x= \dfrac{2\pi n+sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$

$x= \dfrac{2\pi n+ \pi -sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$

In a company, it takes 4 employees 4 days to complete a task. It would take 2 employees 8 days to complete the same task.

Triss [41]

The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant.

This can be illustrated by the givens above.
Scenario 1:
N1 = (4 employees)(4 days) = 16 man-days

Scenario 2:
N2 = (2 employees)(8 days) = 16 man-days

The equation for determining the value of e is equal to,
k = (d)(e)

The answer is the second choice.
