The space diagonal will have length ...
... d = √(1² +4² +2²) = √(1 +16 +4) = √21
_____
This can be found using the Pythagorean theorem. A drawing can help. Find the length of any face diagonal, then use that length as the leg of a right triangle whose hypotenuse is the space diagonal and whose other leg is the edge length not used in the first calculation.
9) 216 in
10) 12 yd
11) 3.75 ft
12) 30 yd
13) 8 ft
14) 26 ft
Answer:
4/5
Step-by-step explanation:
Sin is opposite / hypotenuse
Sin x= 16/20
16/20= 4/5
-3/2x
The rational expression would not be defined only when the denominator is divided by 0
That is:
2x =0
x = 0/2
x =0
Hence it would not be defined when x = 0.
Hope this helps.
Answer: 
Step-by-step explanation:
divided by 
is the same thing as multiplying by 
.
The equation we get is:
With this equation, we can factor each equation:
We can cancel out like terms since they would be dividing each other:
