State the intervals for which the given quadratic is positive and when it is negative.
goblinko [34]

Answer:

  • Positive at (-9, 2)
  • Negative at ( -oo, -9) or (2, + oo)

Step-by-step explanation:

<u>Given function</u>

  • y= -2x^2 - 14x + 36

<u>Getting zero's</u>

  • -2x^2 - 14x + 36 = 0
  • x^2 + 7x - 18 = 0
  • x = ( -7 ± √(49 +72))/2 = ( -7 ± 11)/2
  • x = - 9 and x = 2

<u>As the x^2 has negative coefficient, the function is positive between -9 and 2</u>

  • - 9 < x < 2 or
  • (-9, 2)

<u>And it is negative at:</u>

  • x < -9 and
  • x > 2
  • or
  • ( -oo, -9) or (2, + oo)

a rectangular pool is 8 yards long 6 yards wide and 5 feet deep .convert the measurements of the length and width to feet​
ExtremeBDS [4]

Answer:

1 yard = 3 feet

Keeping this in mind, we need to multiply the yard lengths by 3 to convert the measurements to feet.

8 feet x 3 = 24 yards

6 feet x 3 = 18 yards

5 feet x 3 = 15 yards

So

8 ft = 24 yd

6 ft = 18 yd

5 ft = 15 yd

plz mark brainliest if this helped :)
