Answer:
Step-by-step explanation:
Given function l:
h= -16t² + 26t
where h represents height and t represents time.
The time for dolphin atbthe height 5 feet is given by putting the value of h as 5 in the function,
5 = -16t² + 26t
16t² - 26t + 5 = 0
For this equation: a=16, b=-26, c=5
Use quadratic formula with a=16, b=-26, c=5.
x=(−b±√b2−4ac)/2a
x=−(−26)±√(−26)2−4(16)(5)/2(16)
x=13/16 + 1/16√89 or x=13/16+ −1/16√89
x=1.40 or 0.22
Starting from the y-intercept of ![\displaystyle [0, 2],](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B0%2C%202%5D%2C)
you do 
by either moving two blocks <em>north</em> over three blocks <em>west</em> or two blocks <em>south</em> over three blocks <em>east</em> [<em>west</em> and <em>south</em> are negatives].

Answer:
3240 sq meters
Step-by-step explanation:
Area of garden = 90*60= 5400 square meters.
Flowers grown on = 40%
So, grass grown on = (100 -40)% = 60%
60% of 5400 = 0.6*5400 = 3,240.
So, the area of the garden that is grass = 3,240 square meters
