To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows:
<span>
0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s
Hope this answers the question. Have a nice day.</span>
Answer:
b. -3
Step-by-step explanation:
9(2x+1) < 9x-18
(distribute the 9)
18x+9 <9x-18
(subtract 9 from both sides)
18x<9x-27
(subtract 9x from both sides)
9x<-27
(divide both sides by 9)
x<-3

Answer:
2xy
Step-by-step explanation:
Here, we want to obtain the number with the smallest square
To get this, we simply find the nearest number square which is 2
The nearest x squared which is x (to get x^4)
The nearest y squared which is y (to get y^2)
Thus, the smallest number so we get a square will be; 2xy
