Answer:
Step-by-step explanation:
Given points are
And given transformation is
We will start from left to right.
First transformation is reflection about x-axis.
When we reflect about x-axis
So,
Now next transformation is dilation with a factor 4.
If we do dilation with a factor to the point
New co-ordinates after dilation became
So,
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.
