Looking at the top half, we can see a triangle formed by ABC.
The area of a triangle is found by multiply 1/2 x base x height.
The height would be 1/2 of the overall height of the shape so 14.3 /2 = 7.15.
The area of the top half = 1/2 x 7.15 x 17.2 = 61.49
Since the bottom half is identical to the top half, multiply that area by 2 for the total area:
61.49 x 2 = 122.98 square feet.

Answer: D) 4</h3>
Explanation:
Start at the point (-1,-4). In order to move to (0,0), we must do the following two steps:
- Move 4 units up
- Move 1 unit to the right
This indicates slope = rise/run = 4/1 = 4.
You could use the slope formula to get this same result.
Answer:
1.
2. Required factors: (x - 10) (x - 13)
x = 10, x = 13
Step-by-step explanation:
1.
Graph is intersecting x-axis at points (5, 0) & (11, 0)
Hence, x = 5 & x = 11 are zeroes of the function.
So, (x - 5) & (x - 11) are factors of the quadratic function:
Therefore, required function is:
2.
Plug y = 0
So, x - 10 = 0, x - 13 =0
x = 10, x = 13
Answer:
- 19/12 or - 1 7/12
Step-by-step explanation:
11/12 + ( - 8/12) = - 19/12 = - 1 7/12
Change the denominator for 12, and leave 11/12 alone, but multiply 4 to the numerator of - 2/3.
