Given the function s(t) = -9 -3t, differentiating the function gives the instantaneous velocity. s’(t) = -3 This means that the velocity is not a function of time and is therefore constant. The velocity at t = 8 ( or any time for that matter) is -3 units/time.

Quadrilateral QRST has two pairs of congruentes sides, but it is not a parallelogram. What figure is it? What further condition
Whitepunk [10]

Answer:

The correct answer is:    [C]:

________________________________________________

  " {The figure is a kite.  To be a parallelogram, it would have to have pairs of <em>opposite</em> congruent sides, not just congruent sides. } ."

________________________________________________

Step-by-step explanation:

________________________________________________

Note that "all" squares are "parallelograms" ; and that "all" rectangles are

                "parallelograms" ;  

           yet:  "Not All parallelograms" are "squares" or "rectangles".

________________________________________________

The question asks:

________________________________________________

"Quadrilateral QRST has two pairs of congruent  sides, but it is not a parallelogram.  

What figure is it?  

What further condition would have to satisfy to be a parallelogram? "  .

________________________________________________

So;  we can rule out:

________________________________________________

"Answer choices:

[A]:  "The figure is a square..." ;

________________________________________________

[B]:   "The figure is a rectangle..." ;  <em><u>AND</u></em> :

________________________________________________

[D]: "The figure is a square..."  .

________________________________________________

We are left with:

________________________________________________

Answer choice:  [C]:  

________________________________________________

          " { The figure is a kite.  To be a parallelogram, it would have to have pairs of <em>opposite</em> congruent sides, not just congruent sides. } "  .

Can anyone help me do the question that are circled with red? You don't need to do the graphing calculator thing,, just factor t
stealth61 [152]

Answer:

16. (4 + h)( 11 + h)

17. (2 - x)(20 - x)

18.  (2 + x)(- 12 + x)

19. (6 + m)(- 7 + m)

20. x =4 and 3

21. x = 9 and -3

Step-by-step explanation:

16. 44 + 15h + h² = 44 + 11h + 4h + h² = (4 + h)( 11 + h) (Answer)

17. 40 - 22x + x² = 40 - 20x - 2x + x² = (2 - x)(20 - x) (Answer)

18. - 24 - 10x + x² = - 24 - 12x + 2x + x² = (2 + x)( - 12 + x) (Answer)

19. - 42 - m + m² = - 42 - 7m + 6m + m² =  (6 + m)(- 7 + m) (Answer)

20. x² - 7x + 12 = 0

⇒ x² - 4x - 3x + 12 = 0

⇒ (x - 4)( x - 3) = 0

⇒ x =4 and 3 (Answer)

21.  x² - 6x = 27

⇒ x² - 6x -27 = 0

⇒ x² - 9x + 3x - 27 = 0

⇒ (x - 9)( x + 3) = 0

⇒ x = 9 and -3 (Answer)

Is 17 heartbeats in 15 seconds a unit rate? Why or why not?
g100num [7]
No, because it is not per second. You would have to simplify to per one second for it to be a unit rate. Hope it helps! :)
