places in the same formula. Fortunately, we know what you mean.
H = h + vt - 16t²
You have said that ...
initial height = 5 feet
initial velocity = 20 feet per second, no direction given
time = 1 second
Since you gave us the magnitude of the initial velocity but not its direction,
there are a huge number of possibilities. I'll focus only on two of them:
20 feet per second straight down, and 20 feet per second straight up.
Initial velocity is downward:
H = (5) + (-20) (1) - 16 (1)²
H = 5 - 20 - 16 = 5 - 36 = 31 feet underground after 1 second
Initial velocity is upward:
H = (5) + (20) (1) - 16 (1)²
H = 5 + 20 - 16 = 25 - 16 = 9 feet above ground after 1 second

Yes, these lines are parallel because they are going in the same direction, same distance from each other, and do not ever intersect.
This could also be reworded to same slope but different y-intercepts.

Hello!
Answer:
Step-by-step explanation:
→ We want the value of n - n - p when n = -9 and p = -4.
→ Let's replace n by -9 and p by -4 in the expression:
→ Simplify the expression:
Conclusion:
If n = -9 and p = -4 in the expression n - n - p, this expression is equal to 4.

Answer:
The width of the deck is 2m .
Step-by-step explanation:
Let the width of the pool be represented by w. As stated in the problem a deck of uniform width is to be built so the total width of the pool and deck will be w+w = 2w.
Now the total dimensions can be taken as
10m+ 2w and 5m + 2w of both the pool and deck.
Area = length * breadth
126m ²= (10m+ 2w) ( 5m + 2w )
126= 50 + 30 w+ 4w²
0= 50 -126+ 30 w+ 4w²
0 = 30 w+ 4w²- 76
Taking 2 as common
0= 2( 15 w+ 2w² - 38)
2w²+ 15 w - 38= 0
The above equation is the quadratic equation and can be solved as follows.
a= 2 , b= 15 and c= -38
b= -b±√b²- 4ac/2a
Putting the values
b= - 15±√15²- 4( 2)(-38)/2(2)
b= - 15± 23/4
b= - 38/4 or 8/4
b= 2 m
The width cannot be negative so we ignore the negative value
The width of the deck is 2m .
The can be checked by putting the value in the original equation.
126m ²= (10m+ 2w) ( 5m + 2w )
126m ²= (10m+ 2(2)) ( 5m + 2(2) )
126m ²= (10m+ 4) ( 5m + 4 )
126m ²= 14*9
126m ²= 126m ²

60 is what percent of 72
60 = x% of 72
60 = x% * 72
60 = x/100 * 72
60/72 = x/100
x = 60/72 * 100
x = 83.33%
The correct result would be 83.33%.
60 divided by 12 is 5, and 72 divided by 12 is six.
5/6 equals 0.83
0.83 x 100 is 83, or 83%.
Brainiest would be nice.
