<h3 /><h3>\huge \cal༆ Answer ༄</h3>

<h3>7. Find domain ~ </h3>

  • \sf - 6 \leqslant x < 5

or

  • \sf x ∈[ - 6,5)
<h3>8. Find range ~ </h3>

  • \sf - 2

or

  • \sf x ∈ (-2 , 7]

Find x such that x - 4, x, and 3x - 8 are three consecutive terms in a geometric sequence
Nitella [24]
In a geometric sequence dividing any term by the term before it yields the common multiplier.
Then x/(x+8) = (3x-8)/x
Solving for x:  reduces to x^2-10x +16 factor into (x-2)(x-8)
Then x = 2 or 8
2 produces a sequence of -2, 2, -2 ...
8 produces a sequence of 4, 8, 16 ...

Weegy 1. jane worked 32 hours in one week. if she worked the same number of hours each day for 4 days, how many hours a day did
rusak2 [61]

Well to get to 32 hours and knowing for all 4 days, she worked the same number of hours.


All we have to do is multiply all these numbers by 4 to see which one is equal to 32.


6 * 4 = 28

10 * 4 = 40

8 * 4 = 32

4 * 4 = 16


c. is the correct answer

Which of the equations below represents
Ray Of Light [21]

The equation that represents the graph of the ellipse is x² / 4 + y² / 100 = 1. (Correct choice: D)

<h3>What is the equation of the ellipse represented in the graph?</h3>

Herein we have a representation of an ellipse in the image attached aside, ellipses are characterized by the following <em>standard</em> formula:

(x - h)² / a² + (y - k)² / b² = 1     (1)

Where:

  • (h, k) - Coordinates of the center
  • a, b - Lengths of the semiaxes

Please notice that ellipse will be vertical if b > a, otherwise it will be horizontal. The graph exhibits a <em>vertical</em> ellipse centered at the origin and therefore we conclude that (h, k) = (0, 0) and b > a (b = 10, a = 2). Finally, the equation that represents the graph of the ellipse is x² / 4 + y² / 100 = 1. (Correct choice: D)

WILL GIVE BRAINLIEST! PLEASE HELP! URGENT!
Artemon [7]

Vertical Asimtote: (x-3) this will be the denominator

Horizontal Asymtote: (x-1)^2 (x+3) this will be the numerator

y= a (x-1)^2 (x+3) / (x-3)

Vertical: (x-1/2)

Horizontal: (x-3)

y= a (x-1/2)/(x-3)

I hope this helped?
