We know that
sin(A-B<span>)=sin A cos B - cos A sin B
</span>then
sin(x-45)=sin x cos 45 - cos x sin 45
sin(45)=cos(45)=(√2)/2
sin(x-45)=sin x *[(√2)/2] - cos x*[(√2)/2]-------> [(√2)/2]*[sinx-cosx]
y=sin(x-45)=[(√2)/2]*[sinx-cosx]

using a graph tool
see the attached figure

the answer is
y=[(√2)/2]*[sinx-cosx]

A cylindrical barrel has a radius of 7.8 m and a height of 8.2 m. Doubling which dimension(s) will quadruple the volume of the b

V125BC [204]

Answer:

Doubling the radius of this cylindrical barrel would quadruple the volume.

Step-by-step explanation:

The volume of a cylinder of radius $r$ and height $h$ is:

$V = \pi \, r^{2}\, h$ .

If radius $r$ stays the same, volume $V$ would be proportional to height $h$ . That is, $V = (\pi\, r^{2})\, h$ . Doubling height $h\!$ would only double $V\!$ .

If height $h$ stays the same, volume $V$ would be proportional to $r^{2}$ , the square of the radius. That is, $V = (\pi\, h)\, r^{2}$ . Doubling radius $r\!$ would quadruple $r^{2}\!$ and thus quadruple $V\!$ as required.
