Hmm, it actually doesn't exist because at x=3, that is where the absoluve value turns into 0. the graph has a point at x=3 and there is no slope of a pointy part of a function. I mean the slope is undinfed, it is DNE

PLS HELP!! 9-3 divided by 1/3+1=________.
lawyer [7]
What you need to do is divide the fraction then multiply by the reciprocal of that fraction

So it’ll be 9-3x3+1

Then you multiply the numbers

9-9+1

Eliminate both 9’s, therefore the answer will be 1

What is the sum of the factors of the trinomial x^2-6x+5
andrezito [222]

Its a binomial

\\ \sf\longmapsto x^2-6x+5=0

  • a=1
  • b=-6
  • c=5

If zeros be alpha and beta

\\ \sf\longmapsto \alpha+\beta=\dfrac{-b}{a}

\\ \sf\longmapsto \alpha+\beta=\dfrac{-(-6)}{1}

\\ \sf\longmapsto \alpha+\beta=6

Which describes the cross section of a square prism that passes through vertices A, B, and C?
expeople1 [14]

Answer:

In triangle ABC one side equal 8\sqrt{2} and two sides equal 4\sqrt{13}

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AB=\sqrt{8^2+8^2}=8\sqrt{2}

AC is face diagonal of front face.

AC=\sqrt{8^2+12^2}=4\sqrt{13}

BC is face diagonal of right face.

BC=\sqrt{8^2+12^2}=4\sqrt{13}

AC=BC≠AB

Hence, In triangle ABC one side equal 8\sqrt{2} and two side equal 4\sqrt{13}
