Answer:

c.(0, -√5) and (0, √5)

Step-by-step explanation:

The equation represents an ellipse centered on origin (0,0). First, the formula is rearranged to its cannonical form:

\frac{x^{2}}{4} + \frac{y^{2}}{9} = 1

The foci are located in the lines of the semimajor axes, so, the distance between the center and any of the foci is:

c = \sqrt{9 - 4}

c = \sqrt{5}

The foci are located at (0, -\sqrt{5}) and (0,\sqrt{5}). Hence, the answer is C.

erastovalidia [21]

Answer:

$25 per hour

Step-by-step explanation:

Net pay= $1200

Deductions= $300

Hours worked= 60

Total pay=$1200+ $300= $1500.

Since her net pay is the money left after deductions, so we add the netpay and deductions to get her total pay.

Therefore, to find her hourly pay, we simply divide the total pay by the hours worked,so we have 1500/60= $25/hour

the sum of two consecutive integers is three times their difference.what is the larger number.please help!​
Vesnalui [34]

9514 1404 393

Answer:

  2

Step-by-step explanation:

If n is the larger integer, n-1 is the smaller. The difference of consecutive integers is 1, so their sum is ...

  n +(n -1) = 3(1)

  2n = 4 . . . . . . . . . add 1

  n = 2 . . . . . . . . . . divide by 2

The larger integer is 2.
