A. Are the expressions 3(m - 2) + 2(m - 2) and 50m - 2) equivalent expressions?

miss Akunina [59]2 years ago

Answer:

Step-by-step explanation:

3(m-2)+2(m-2)

3m-6+2m-4

3m+2m-6-4

5m-6-4

5m-10

The expressions 3(m-2)+2(m-2) and 50m-2 are not equivalent expressions.

After simplifying the first expression 3(m-2)+2(m-2) in part (a), we got 5m-10, which is different from the second expression, 50m-2.

Find the rectangular coordinates of the point ( -3, 1/2 π)
alexdok [17]

Answer:

x = -3 cos (\frac{\pi}{2})= 0

y = -3 sin (\frac{\pi}{2})= -3

And then the rectangular coordinates for this case are :

(x = 0 , y = -3)

Step-by-step explanation:

We have the following point given P = (-3, \frac{\pi}{2}) and we want to conver from polar to rectangular coordinates and we need to use the following formulas:

x = r cos \theta

y = r sin \theta

For this case we have that:

r = -3

And:

\theta = \frac{\pi}{2}

Replacing we got:

x = -3 cos (\frac{\pi}{2})= 0

y = -3 sin (\frac{\pi}{2})= -3

And then the rectangular coordinates for this case are :

(x = 0 , y = -3)

y^2\sqrt[8]{8}

Step-by-step explanation:

\sqrt[8]{8*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y}

Since there are eight y's in two groups we can take them out which turns into

y^2\sqrt[8]{8}
