The area of the trapezoid is 57.5 square inches.

If you draw out the description, you will see that your trapezoid can be divided into a rectangle that is 9 x 5 and an isosceles right triangle with a base of 5 and height of 5. 

Just find the areas of both and add them together.

Rectangle:
5 x 9 = 45

Triangle:
0.5 x 5 x 5 = 12.5

45 + 12.5 = 57.5

Each table represents some values of a function. If the slope between two pairs of points are equal, assume the function is line
kolbaska11 [484]
The slope of a function is the ratio of the rise (y2 - y1) and the run (x2-x1) of a function, In this case the slope would be (1 - 0) / (1-0) = 1. The y-intercept would be the y value when x is zero. From the table we see this will have a value of zero. The equation for this function would be y = x. We use the said equation to fill the blanks in the table.

A square shed has a floor area of 156.25m square. what is the length of the diagonal
slava [35]
Square root 156.25 to get the values of the sides of the square. You will get 12.5m for each side. 

Now that you have the side values, use Pythagoras' Theorem to solve for the diagonal. Let's call the diagonal x,

c^2 = a^2 + b^2
x^2 = 12.5^2 + 12.5^2
       = 312.5

Square root both sides to get x,

x = 17.68m (2 d.p)

HOPE THIS HELPED! Ask me if there is anything you don't understand from this working :D
