Answer:
C. hyperbola; 
Step-by-step explanation:
The given conic has equation:
Divide through by 225.
This is a hyperbola centered at the origin.
The hyperbola has been translated from the origin to (0,5).
The translated hyperbola will have equation;
Multiply through by 225.

Received math class requested 315 64 379
Did not get math class requested 41 80 121
Total 356 144 500
Honor roll: request granted: 315/356 = 0.88 x 100% = 88%
Not Honor roll request granted: 64/144 = 0.44 x 100% = 44%
Honor roll students were given preference in granting request than those not in the honor roll.</span>
Answer:
$90,962.66
Step-by-step explanation:
The formula for this is, where V = amount after t years:
V = P(1 + r/n)^nt where P is the amount invested, r = the rate as a decimal fraction, n is the number of times interest compounded each year and t = the number of years.
Here, V = 340,000, r = 0.07, n = 4 , t = 19 and P is to be found.
340,000 = P(1 + 0.07/4)^(4*19)
340,000 = P( 1.0175)^76
P = 340,000 / (1.0175^76)
P = $90,962.66
