Answer:
Step-by-step explanation:
The pressure is equal to the atmospheric pressure 101 kN/m plus 8 kN/m for every meter below the surface, therefore;
a. expression for pressure is given by,
............................... (1)
where d = depth below the surface in meter.
b. to find the depth at any pressure, equation (1) above is rearranged to make depth (d) subject of the formula
as an example, to find depth at pressure of 200N/m
d = (200 - 101)/8 = 12.375 meters
depth is 12.375 meters below the surface.
The graph which represents Charlies distance from her car at different times is indicated as attached. The schedule of her movement is also attached. This type of graph is called Distance Time Graph.
<h3>
What is a distance-time graph?</h3>
A distance-time graph can show the distance traveled while an item moves in a straight line.
The gradient of the line in a distance-time graph is equal to the object's speed. The item is travelling more quickly the steeper the line and the larger the gradient.
See the attached for Charlies Distance - Time movements visualized in a graph.

Answer:
Step-by-step explanation:
<u>A and B are same side interior angles and hence supplementary:</u>
<u>Substitute values and solve for x:</u>
- 6x - 18 + 14x + 38 = 180
- 20x + 20 = 180
- 20x = 160
- x = 160/20
- x = 8
<u>Find the measure of ∠A:</u>
39.277 is how long the border is
