Answer:
114.31 nautical miles per day
Step-by-step explanation:
Use formula

where S is the distance, t is time and v is rate.
If S=11431 nautical miles and t=100 days, then

Answer:
A and B
Step-by-step explanation:
1) Distance to the focus
From (x,y) to the focus(2,-4) {using distance formula}
=√(x-2)²+(y+4)²
2) Distance to the directrix
Is, y+p where P here is (-6)
So
d2 = y+p
= y+(-6)
= y-6
Since both A and B are squared they can be added normally. So A+B would be
(5x^2)+(-3x^2+6) = 2x^2+6.
In order to figure out the number of fossilized snail shell, multiply 21% by 300. first change 21% into a decimal, in order to do that, move the percent symbol two spaces to the left, and replace the "%" symbol to a decimal. 0.21 X 300= 63
so 21% of 300 is 63
