2. Find the product of 2/7 x 5/6

alex41 [277]

Multiply the numerators together and the denominators:

2/7 x 5/6 = (2x 5) / (7x6) = 10/42 this can be reduced to 5/21

The answer is 5/21

-4/5 x 7/10 = (-4x7) / (5x 10) = -28/50

This can reduce to -14/25

.find the slope and y intercept form equation from the table

AnnZ [28]

Answer:

y = 4x - 26

Step-by-step explanation:

The change in y is 4 when the change in x is 1.

So the slope is change in y/change in x = 4/1 = 4

y = mx + b

30 = 4(14) + b

30 = 56 + b

b = - 26

Therefore, y = 4x - 26

I don’t know how to solve this

Lady_Fox [76]

Answer:

$\theta =2\pi k,\ \ k\in Z\ \\\text{or}\ \\\theta=-\dfrac{2\pi}{3}+2\pi k,\ \ k\in Z$

Step-by-step explanation:

Given:

$\cos \theta-\sqrt{3}\sin \theta=1$

Divide this equation by 2:

$\dfrac{1}{2}\cos \theta-\dfrac{\sqrt{3}}{2}\sin \theta=\dfrac{1}{2}$

Note that

$\cos \dfrac{\pi }{3}=\dfrac{1}{2}\\ \\\sin \dfrac{\pi }{3}=\dfrac{\sqrt{3}}{2}$

So, the previous equation is

$\cos \dfrac{\pi}{3}\cdot \cos \theta-\sin \dfrac{\pi}{3}\cdot \sin \theta=\dfrac{1}{2}$

Remind that

$\cos x\cos y-\sin x\sin y=\cos (x+y),$

then

$\cos \left(\dfrac{\pi}{3}+\theta\right)=\dfrac{1}{2}$

The solution of this equation is

$\dfrac{\pi}{3}+\theta=\pm \arccos \dfrac{1}{2}+2\pi k,\ \ k\in Z\\ \\\dfrac{\pi}{3}+\theta=\pm \dfrac{\pi}{3}+2\pi k,\ \ k\in Z\\ \\\theta =2\pi k,\ \ k\in Z\ \text{or}\ \theta=-\dfrac{2\pi}{3}+2\pi k,\ \ k\in Z$
