Answer:
3060
Step-by-step explanation:
<u>Find the cross-sectional area first of the trapezium</u>
So,
which is 40 / 2 x 15 = 20 x 15 = 300
Since there are 2 trapeziums (on the front and back): 300 x 2 = 600
<u>Find the Area of the Rectangles</u>
The first rectangle on the top would be: 6x30 = 180
The slanted rectangle on the right would be: 25x30 = 750
The rectangle on the bottom would be: 30x34 = 1020
The hidden rectangle on the left would be: 17 x 30 = 510
So by combining all these calculations, you will get the total surface area which is:
600 + 180 + 750 + 1020 + 510 = 780 + 1770 + 510 = 2550 + 510 = 3060

Answer:
The lines are perpendicular
Step-by-step explanation:
we have
isolate the variable y
----> equation A
The slope of the line A is
-----> equation B
The slope of the line B is
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
The answer is C. Explanation: The line isn’t a straight line, so it can’t be a linear line. Then, do the vertical line test to see if the line is a function (to do this, draw a vertical line through the graph, and see if it passes more than one point on the graph. If the vertical line passes any more than one point on the graph on any spot, it is not a function), and since the graph fails the vertical line test, it is not a function. Therefore, the answer is C.
