In the diagram below AE = 6, EB = 3, and DE = 2. Find CE
cluponka [151]

Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.

In your case,

AE\cdot EB=CE\cdot ED.

If AE = 6, EB = 3, and DE = 2, then

6\cdot 3=CE\cdot 2,\\ \\CE=\dfrac{6\cdot 3}{2}=9.

Answer: correct choice is D.

Write a rule y=f(x) that would produce the graph.
katen-ka-za [31]

Answer:

  y = | x+2 | -1

Step-by-step explanation:

The absolute value function is shifted left 2 units and down 1. That makes it ...

  y = abs(x+2) -1

Using the usual symbols for absolute value:

  y = |x+2| -1

_____

The translation transformation is ...

  y = f(x -a) +b

to translate the graph of f(x) right by "a" units and up by "b" units. Here, we have a translation left 2 and down 1, so a=-2, b=-1. The original function is the absolute value function in this case.

I need help on this problem, mostly understanding though, please help me
mars1129 [50]

well, let's notice something, a cube, all equal sides, has a side of 6, thus its volume is simply 6*6*6 = 216 cm³.

now, a rectangular prism, is a cuboid as well, but with varying dimensions.

let's notice something 6*6*6 is simply a multiplication of 3 numbers, let's then do a quick <u>prime factoring</u> of those numbers, well, 6 factors only into 2 and 3, so then the product of 6*6*6 can really be rewritten as (2*3)(2*3)(2*3).

well, regardless on how we rearrange the factors, the product will be the same, commutative property, so the rectangular prism will more or less have the same product and thus just about the same prime factors.

so let's rearrange on say hmmm height = 3 cm, length = 3*3 cm and width = 2*2*2 cm, notice, is still the same prime factors, 3*9*8 = 216 cm³.

Check the picture below.
