32 floors
32*11=total feet from ground to top
h=297-4.4t
set 11=297-4.4t to find the time it will take since each floor is 11 ft high
Answer:
A = (-1,5) or (-1,-3)
Step-by-step explanation:
A = (-1,y) B = (2,1)
(Distance from A to B) = √[(-1-2)² + (y-1)²] = 5
=√[9 + y² - 2y + 1] = 5
Squaring on both sides
= y² - 2y + 10 = 25
=y² - 2y -15 = 0
= (y-5)(y+3) = 0
y = 5 or -3
Therefore, A = (-1,5) or (-1,-3)
20 miles/2 hours = 10 miles/1 hour, therefore her average speed is 10mph
