Answer:

b. 30°

Step-by-step explanation:

In quadrilateral OTPR, angles O and P are supplementary.

angle P = 180° -angle O = 180° -150°

angle P = 30° . . . . matches choice B

The equation of the line in the graph is y=___ x+=_____ (-1,-1)

il63 [147K]

Answer:

y= 1x-1 or y= x-1

Step-by-step explanation:

Make sure we know the equation y = mx +b

Remember M= slope, B= Y-intercept

We can see that the slope (rise over run) is 1 so we plug in the 1 for M

Y= 1x +b

Now we have to look for the Y-intercept which is -1

making our equation now: Y= 1x -1

Over what interval is the function differentiable? Y=3/2(x-1)

jolli1 [7]

Answer-

The interval where the function is diffrentiable is

$[-\infty,1)\ \bigcup\ (1,\infty]$

Solution-

The given expression is,

$y=\dfrac{3}{2(x-1)}$

The function will be differentiable where it is continuous and it will not be differentiable, where the function is not continuous.

The function continuous everywhere except at x = 1, because

$\Rightarrow 2(x-1)=0\\\\\Rightarrow x-1=0\\\\\Rightarrow x=1$

at x = 1, its limit does not exist.

Therefore, apart from x=1, this function is differentiable everywhere. The interval will be

$[-\infty,1)\ \bigcup\ (1,\infty]$
