3.) 3 faces. 4 edges. 3 V
4.) 5 faces. 5 edges. 3 V
5.) 2 faces. 1 edge. 1 V
6.) 3 faces. 0 edges. 1 V
7.) 1 face. 0 edges. 2 V's
I'm iffy on the V's.
When it hits the ground the height would be 0.
Set h to 0 and solve for t ( time)
0 = -16t^2 + 112t + 144 divide both sides by -16:
T^2 -7t -9
Factor the polynomial :
( t- 8.1) (t+1.1
Solve for t setting each equation to 0:
T = 8.1 or t = -1.1
Time has to be positive, so the answer is
8.1 seconds
Depending on how everything gets rounded it could also be 8 seconds.
Answer:
y+9=-1(x-4)
Step-by-step explanation:
Point Slope Form is:

When:
'm' is the slope.
is the coordinate.
We are given the slope of -1 and the coordinate of (4,-9).
So:

Using the information and replacing the values we get:

So, the line equation in point slope form should be: y+9=-1(x-4)

Answer:
14 feet below. the deck.
Step-by-step explanation:
That would be (20 + 78 - 85 +103 - 110 ) feet above the ground
= 6 feet above the ground.
That is 20 - 6 = 14 feet below the deck.
Answer:
Let x and y be the two positive integers the Christopher is thinking.
x is equal to 7
and y =20
