Answer:
The change in elevation is -134 ft
Step-by-step explanation:
Given;
initial depth of the submarine, d₁ = 235 ft
final depth of the submarine, d₂ = 101 ft
The change in the elevation of the submarine is given by;
Δd = d₂ - d₁
Δd = 101 ft - 235 ft
Δd = -134 ft
The change in elevation is negative because the submarine is moving closer to the surface.
Therefore, the change in elevation is -134 ft
Answer:20,12
Step-by-step explanation:
32×5/8=20
32×3/8=12
Answer:
2 is the absolute mean deviation
Step-by-step explanation:
absolute mean deviation is
the average of the differences of the data from the average
8, 8, 4, 12
1. take the average
8+8+4+12=32 -> 32/4 = 8
2. subtract each number from this average
8 - 8 = 0
8 - 8 = 0
4 - 8 = 4 (there are no negative answers)
12 - 8 = 4
3. take the average of these subtractions
0+0+4+4=8 -> 8/4 = 2
4. answer: 2 is the absolute mean deviation
Answer: y=4x-4
Step-by-step explanation:
To find the equation fo the line parallel to the given line, we can use the given point to find the y-intercept. We know that the slope must stay the same because parallel lines NEVER touch or cross. This means that the slope MUST be the same.
y=4x+b
We can use the given point to find the y-intercept.
8=4(3)+b [multiply]
8=12+b [subtract both sides by 12]
b=-4
Now that we have found the y-intercept, we can complete the equation.
y=4x-4
Answer:
QRS.
Step-by-step explanation:
The order of the letters must reflect the equal angles and their order.
So Q corresponds to L, R corresponds to M and S corresponds to N
So the answer is QRS.
