Bumek [7]

Given:

The four expression in the options.

To find:

Which expression is equal to –1.

Solution:

In option A,

$\cot \left(\dfrac{\pi}{4}\right)=1$

In option B,

$\sin \left(\dfrac{\pi}{2}\right)=1$

In option C,

$\sin \left(\dfrac{3\pi}{2}\right)=\sin \left(\pi+\dfrac{\pi}{2}\right)$

$\sin \left(\dfrac{3\pi}{4}\right)=-\sin \left(\dfrac{\pi}{2}\right)$ $[\because \sin(\pi+\theta)=-\sin \theta]$

$\sin \left(\dfrac{3\pi}{4}\right)=-1$

In option D,

$\tan \left(\dfrac{5\pi}{4}\right)=\tan \left(\pi+\dfrac{\pi}{4}\right)$

$\tan \left(\dfrac{5\pi}{4}\right)=\tan \left(\dfrac{\pi}{4}\right)$ $[\because \tan(\pi+\theta)=\tan \theta]$

$\tan \left(\dfrac{5\pi}{4}\right)=1$

Therefore, the correct option is C.

A construction worker is looking at blueprints drawn to a 1/20 scale and notices that a wall is 0.5 feet by 0.25 feet. He claims

Gnoma [55]

Answer:

incorrect

Step-by-step explanation:

we are finding area which is squared, or we can put it in an equation, (0.5*20)*(0.25*20) or 0.5*0.25*20^2 which equals 50 but (0.5*0.25)*20 only equals 2.5 therefor he is incorrect and the correct answer would be 20^2 or 400 times the area.

hope this helps :)
