Answer:

Step-by-step explanation:

Let the smallest number be n,

then the three numbers are n, n+1 and n+2

Therefore, n+(n+1)+(n+2)=120

Collecting like terms,

n+n+n=120-1-2

3n=117

n=117/3

n=39

Therefore the numbers are 39,40 and 41.

And the smallest number is 39.

One angle of an isosceles triangle measures 40°. Which other angles could be in that isosceles triangle? Choose all that apply.

V125BC [204]

70°

(the sum of the angles of a triangle is 180°

180 - 40 = 140.

140/2 = 70

The other 2 angles are 70°

70° + 70° + 40° = 180°).

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

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

I REALLY NEED THIS RIGHT NOW PLEASE HELP Are the given lines parallel? How do you know? y=2 and y = -4

Novay_Z [31]

Answer:

Yes, they have the same slope

Step-by-step explanation:

Both y=2 and y=-4 have the same slope, a slope of zero, because when they are graphed, both of them form a straight horizontal line. And since they both form a straight horizontal line, they are parallel because they have the same slope.

Hope this helped! :)
