1) 8

2) 6(5x+2y) factor out greatest common factor

3) 10.8 just move over decimal two places to the left.

4) 30t=150? Then t=5kg Im not sure what the last one is asking, but I’m assuming it’s to solve for t.

2sinxcosx = cosx solve for x, how can i do it

VladimirAG [237]

$2\sin x\cos x=\cos x\\\\2\sin x\cos x-\cos x=0\\\\\cos x(2\sin x-1)=0\iff\ \cos x=0\ or\ 2\sin x-1=0\\\\\cos x=0\ if\ x=\dfrac{\pi}{2}+k\pi\\\\2\sin x-1=0\\\\2\sin x=1\\\\\sin x=\dfrac{1}{2}\ if\ x=\dfrac{\pi}{6}+2k\pi\ or\ x=\dfrac{5\pi}{6}+2k\pi\\\\Answer:\boxed{x=\dfrac{\pi}{2}+k\pi\ or\ x=\dfrac{\pi}{6}+2k\pi\ or\ x=\dfrac{5\pi}{6}+2k\pi\ /k\in\mathbb{Z}/}$

Suppose that v1(t)=100cos(ωt)and v2(t)=100sin(ωt). Use phasors to reduce the sum vs(t)=v1(t)+v2(t) to a single term of the form

GuDViN [60]

Answer:

$vs(t)=152.08cos(\omega t -45)=152.08\angle-45$

Step-by-step explanation:

A tension expressed in form:

$V(t)=Vm*cos(\omega t+\phi)$

It can be converted directly into a fasor:

$V(t)=Vm\angle \phi$

If the function is a positive sine we subtract 90 °

$V(t)=Vm*sin(\omega t+\phi)=Vm*cos(\omega t+\phi-90)$

So:

$v1(t)=100cos(\omega t)= 100\angle0\\v2(t)=100sin(\omega t)=100cos(\omega t-\ph90)=100\angle -90$

$vs(t)=v1(t)+v2(t)=100\angle 0 +100\angle-90=152.0811931\angle-45\approx152.08\angle-45$

Therefore:

$vs(t)=152.08\angle-45=152.08cos(\omega t -45)$

The ratio of the length to the width of a rectangular field is 3 to 2. If the field is 150 yards long, how wide is the field?

Leviafan [203]

Answer:

The field is 100 yards wide.

Step-by-step explanation:

Given that the relationship between the length and width of the rectangular field is 3 to 2, and that said field is 150 yards long, the following calculation must be performed to determine its width:

((150/3) x 2) = X

50 x 2 = X

100 = X

Thus, the common largest divisor between both numbers is obtained, and the relationship from 3 to 2 is established based on said number. Therefore, the rectangular field is 100 yards wide by 150 yards long.
