Answer:
C. Yes, because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
The list of x-values is {-1, 0, 2, 4, 7}. We note that no two are the same, so this is a functional relation.
The set of ordered pairs is a function because each x-value corresponds to exactly one y-value.
Answer:
Step-by-step explanation:
"-y (less than or greater than sign) 136" translates into two separate inequalities:
-y < 136 and -y > 136.
You want to solve for y in each case. To do this, multiply each inequality by "-1" and then immediately change the direction of the inequality sign.
For example: -1(-y < 136) => y > -136.
That may be any kinda right circular cylinder it always contain a net like attachment.
So
- There is a rectangle which is not a square for LSA
- And two bases which are circles
Option D
If the object hit the ground, then this mean that the height is 0, right?
so solve for it like this:
0= -16t^2+144
-144 = -16t^2
Divide by (-16)
9= t^2
square root both sides
t= 3 or -3
there is no negative time then the object will hit the ground after 3 secs
