Answer:
Tetragonal unit cell.
Step-by-step explanation:
A unit cell is the smallest part of a material which is formed by a well arranged lattice points. Some common types are; face centered, body center, tetragonal, cubic etc
Tetragonal unit cell has a square top and base, with rectangular sides. The internal angles are 
each, and consists of molecules, atoms, or ions (lattice points) arranged at each corners of the unit cell.
The crystal as described in the given question is a tetragonal unit cell.
Answer:
Step-by-step explanation:
- ED = FG = 4, easy to calculate
- ED ║ FG, both are vertical line segments
- EF ║ DG as the slopes are same
- m(EF) = (7-6)/(6-1) = 1/5
- m(DG) = (3-2)/(6-1) = 1/5
As we see the opposite sides are parallel and congruent. This is the property of a parallelogram
When using the distance formula, you are building a right triangle whose hypotenuse connects two given points. The correct answer is C, right triangle.
Answer:
Step-by-step explanation:
Let the first integer be x, then the next is x+1.
x(x + 1) = 3(x + 1) + 4
x^2 + x = 3x+ 3 + 4
x^2 + x - 3x - 7 = 0
x^2 - 2x - 7 = 0
Solving this does not give an integer so maybe there's something wrong with the question??
The equation that best represents the total earnings for the salesman is letter c which is e=40,000+200 xc
It is because, in order to get the full earnings, you have to add the base salary to the commission that the salesman receives. Whereas, the $40,000 is attached to the commission where the $200 is multiplied to c (every car the salesman sells
