Answer:
A)The sketches for the required planes were drawn in the first attachment.
B)The sketches for the required directions were drawn in the second attachment.
To draw a plane in a simple cubic lattice, you have to follow these instructions:
1- the cube has 3 main directions called "a", "b" and "c" (as shown in the first attachment)
2- The coordinates of that plane are written as: π:(1/a₀ 1/b₀ 1/c₀) (if one of the coordinates is 0, for example (1 1 0), c₀ is ∞, therefore that plane never cross the direction c).
3- Identify the points a₀, b₀, and c₀ at the plane that crosses this main directions and point them in the cubic cell.
4- Join the points.
To draw a direction in a simple cubic lattice, you have to follow these instructions:
1- Identify the points a₀, b₀, and c₀ in the cubic cell.
2- Draw the direction as a vector-like (a₀ b₀ c₀).
Answer:
82.62%
Explanation:
The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
From the normal distribution table, P(11.85 < x < 12.15) = P(-1.36 < z < 1.36) = P(z < 1.36) - P(z < -1.36) = 0.9131-0.0869 = 0.8262 = 82.62%
Answer:
present cost = $302218.15
Explanation:
given data
cost of the work 1st year A1 = $100,000
cost of the work 2nd year A2 = $85,000
cost of the work 3rd year A3 = $70,000
cost of the work 4th year A4 = $55,000
cost of the work 5th year A4 = $40,000
interest rate r = 6% = 0.06
to find out
present worth cost is for the first 5 years
solution
present worth cost will be here as per given equation
present cost = .........................1
here r is rate of interest and A is amount given
put here value we get
present cost =
present cost = $302218.15
