B
Step-by-step explanation:
If you're using a Casio calculator you can just change the mode to table mode. Put the equations as they are,decide the value of the X axis you want to start at and where you want to end. The step you can use 1 if you want. Press = button. You'll have the co-ordinates. Plot the co-ordinates of each equation and see which one gives a straight line graph. I started at -4 and ended at 5 and I used step 1

Answer:
The lateral height of the square pyramid is ![5.8\ ft](https://tex.z-dn.net/?f=5.8%5C%20ft)
Step-by-step explanation:
step 1
Find the surface area of the cube
The surface area of the cube is equal to
![SA=6b^{2}](https://tex.z-dn.net/?f=SA%3D6b%5E%7B2%7D)
where
b is the length side of the cube
w have
![b=6\ ft](https://tex.z-dn.net/?f=b%3D6%5C%20ft)
substitute
![SA=6(6^{2})=216\ ft^{2}](https://tex.z-dn.net/?f=SA%3D6%286%5E%7B2%7D%29%3D216%5C%20ft%5E%7B2%7D)
step 2
Find the lateral height of the square pyramid
we know that
the surface area of the square pyramid is equal to
![SA=B+4(\frac{1}{2}bh)](https://tex.z-dn.net/?f=SA%3DB%2B4%28%5Cfrac%7B1%7D%7B2%7Dbh%29)
where
B is the area of the base
b is the base of the lateral triangle (base of the square)
h is the lateral height of the square pyramid
![B=(10^{2})=100\ ft^{2}](https://tex.z-dn.net/?f=B%3D%2810%5E%7B2%7D%29%3D100%5C%20ft%5E%7B2%7D)
-----> is the same surface that the cube
![b=10\ ft](https://tex.z-dn.net/?f=b%3D10%5C%20ft)
substitute the values and solve for h
![216=100+4(\frac{1}{2}*(10)*h)](https://tex.z-dn.net/?f=216%3D100%2B4%28%5Cfrac%7B1%7D%7B2%7D%2A%2810%29%2Ah%29)
![216-100=20h](https://tex.z-dn.net/?f=216-100%3D20h)
![h=116/20=5.8\ ft](https://tex.z-dn.net/?f=h%3D116%2F20%3D5.8%5C%20ft)
Answer:
m < 5=27°
Step-by-step explanation:
we know that
When a transversal passes through two lines, the angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
In this problem
The transversal is the diagonal BD
The two lines are AB and CD
m < 5 and m < 2 are alternate interior angles
we have that
The two lines are parallel
AB || CD
therefore
m < 5= m < 2
we have that
m < 2=27°
so
m < 5=27°
