Answer:
![xy=wz](https://tex.z-dn.net/?f=xy%3Dwz)
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill =
km/min
Time taken up the hill =
minutes
Speed of Wilmer down the hill =
km/min
Time taken up the hill =
minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
![Distance = Speed \times Time](https://tex.z-dn.net/?f=Distance%20%3D%20Speed%20%5Ctimes%20Time)
Distance up the hill = ![y\times x =xy\ kilometers](https://tex.z-dn.net/?f=y%5Ctimes%20x%20%3Dxy%5C%20kilometers)
Distance down the hill = ![z\times w =wz\ kilometers](https://tex.z-dn.net/?f=z%5Ctimes%20w%20%3Dwz%5C%20kilometers)
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
![xy=wz](https://tex.z-dn.net/?f=xy%3Dwz)
Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct

Answer:
-1
Step-by-step explanation:
We can use the formula to find slope
(y2-y1) / (x2-x1)
y1 is the first Y coordinate in the first pair
y2 is the second one in the first pair
X1 is the first X coordinate in the frst pair
x2 is the second one In the second pair.
so if we put it together it’d look liek this
(5- (-) 2) / (-4 - 3)
5+2 / -4 + -3
7/-7
or -1
