<span>The formula is area of trapezoid = average base x average height
We're going to do this in reverse.
Area = 80.75
[(7 + 12)/2] = 9.5 (height)
height = 80.75 / 9.5 = 8.5
The height is 8.5, so the answer is D.</span>
First find the length of the longest leg
x^2 = 13^2 - 5^2 ( by the Pythagoras theorem)
x^2 = 144
x = 12
Area of the traingle = 1/2 * base * height
= 1/2 * 5 * 12
= 30 units^2
Answer:
See attached image for the requested graph
Step-by-step explanation:
The values completed in the table and text boxes as shown, are all correct.
For the plotting of the points and drawing of the line, please see the attached image.
Given that the range of the signal is a quadratic function:
(x-h)^2 = 4a (y - k)
(5-4)^2 = 4a (4 - 2)
4a =1/2 therefore,
(x -4)^2 = (1/2)(y – 2)
The road is a line.
Slope of the road is (7 -2)/(-3 -8) =-5/11
Therefore the equation of the line:
5x + 11y = 5(8) + 11(2)
5x + 11y = 62
