the answer would be 12 minutes
Step-by-step explanation:
Answer:
y = -1/10x^2 -1/2
Step-by-step explanation:
The equation for a parabola with focus (a, b) and directrix y = d is ...
y = 1/(2(b -d))(x -a)² +(b +d)/2
__
For the given focus and directrix, we have ...
- a = 0
- b = -3
- d = 2
- y = 1/(2(-3-2))(x -0)² +(-3+2)/2
Simplified, the equation is ...
y = -1/10x² -1/2
I’m not so sure about this one but my guess would be maybe C
Answer:
Store B
Step-by-step explanation:
Store A
20% is just 1/5 in percent form
22.00= 22*1/5 = 22/5 = 4.40
22.00-4.40=17.6
Store B
22.50-5=17.5
Now you can see that 17.5 is less than 17.6 by 0.1
