Answer:
Step-by-step explanation:
We are given the position function and need to find the value of t when h<17.
Create an inequality that represents this situation:
The "less than" sign makes this very specifically a conjunction problem as opposed to a disjunction. That's important to the solution. But we'll get there.
The simplest way to solve this is to subtract 81 from both sides:
then divide both sides by -16:
Notice now that the sign is facing the other way since we had to divide by a negative number. Now it's a disjunction. The solution set to this inequality is that t>2 or t<-2. First and foremost, time will never be negative, so we can disregard the -2. Even if that was t<2, the more time that goes by, the greater the time interval is, not the lesser. It's the "<" that doesn't make sense, not only the -2. The solution to this inequality is
t > 2 sec. That means that after 2 seconds, the height of the ball is less than 17 feet.
Answer:
-1/4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-8-(-5))/(0-(-12))
m=(-8+5)/(0+12)
m=-3/12
simplify
m=-1/4

Answer:
y = 4x - 2
Step-by-step explanation:
slope = 4
y -6 = 4 ( x- 2 )
distribute the 4 to ( x - 2 )
y - 6 = 4x - 8
add 6 to both side
y = 4x - 2
Hopefully this helps you understand this concept.
Answer:
1, 4, 9, 16, 25, etc
Step-by-step explanation:
a perfect square is a whole number multiplied by itself. it can be written with the notation ^2
to find a perfect square, simply square or bring to the 2nd power, any whole number
for example 9^2
this means that 9 is multiplied by ITSELF 2 times, it is NOT 9*2
it can also be written as 9*9=81
