A scuba diver dove from the surface of the ocean to an elevation of −49 9/10 feet at a rate of −9.5 feet per minute. After spend
laila [671]

Answer:

Rate of change  =  4,06 f/min

Step-by-step explanation:

The ascendent length  28 9/10   =  289/ 10

The time for that ascendent maneuver is total time 17 1/8 minutes  - spended time in the elevation 10 minutes, then

17 1/8  =  137/8

137/8  - 10   =  ( 137 - 80 ) /8   =  57/8 minutes

The rate of change in the diver´s elevation is

289 / 10 / 57/8

Rate of change  =  289*8/ 57*10

Rate of change  =  2312 / 570 ft/min

Rate of change  =  4,06 f/min

find four solutions for the following linear equations your answer must include at least two positive numbers for X and at least
sattari [20]

9514 1404 393

Answer:

  (-18, 14), (-9, 9), (9, -1), (18, -6)

Step-by-step explanation:

Since there is a 9 in the denominator of the coefficient of x, we will get integer solutions only if x is a multiple of 9. Suitable values meeting the problem requirements are x ∈ {-18, -9, 9, 18}. Then the corresponding values of y are ...

  y = -5/9(-18) +4 = 10 +4 = 14

  y = -5/9(-9) +4 = 5 +4 = 9

  y = -5/9(9) +4 = -5 +4 = -1

  y = -5/9(18) +4 = -10 +4 = -6

The four solutions we have found are ...

  (-18, 14), (-9, 9), (9, -1), (18, -6)

Using the equation x squared minus c equals 0 , what value of c has 9 and -9 as solutions.
Svetach [21]

9514 1404 393

Answer:

  c = 81

Step-by-step explanation:

The equation x² -c = 0 can be factored as ...

  (x -√c)(x +√c) = 0

which has roots ±√c.

The roots are given as ±9, so we have ...

  ±9 = ±√c

  c = (±9)² = 81

The value c = 81 makes the equation have ±9 as solutions.

  • x²-3x+2x-6=0
  • x(x-3)+2(x-3)=0
  • (x+2)(x-3)=0
  • x={-2,3}

ZEros of reciprocal function

  • x={-1/2,1/3}

The equation

  • x²-(-1/2+1/3)x-(1/2)(1/3)=0
  • x²-1/6x-1/6=0
