The answer is 9.36. There is nine which equals 9, "and" means point or the decimal point and six means 6 and "hundredths" represents the position of the number which is in the hundredths place. When you count numbers to the right, you add "ths" so if there wasn't a 6 and just a 3, then it would be tenths.
Step-by-step explanation:
The cartesian graph consists of x and y axes, while the cosine graph is made of and y axes. This means that each value of x has to be converted in to represent a corresponding point in cosine graph.
Thus,
x = cos
or,
For point (1, 0)
y = cos
y = cos(0)
y = 1
Point in cosine graph = (0, 1)
For point (0, 1)
y = cos
y = cos(90)
y = 0
Point in cosine graph = (90, 0)
For point (-1, 0)
y = cos
y = cos(180)
y = -1
Point in cosine graph = (180, -1)
For point (0, -1)
y = cos
y = cos(90)
y = 0
Point in cosine graph = (90, 0)
Answer:
+) the area of the original house is:
(x + 8)(x + 12) = x² + 20x + 96.
+) the area of the new addition is:
(x + 6)x = x² + 6x
+) the total area of the house is:
x² + 20x + 96 + x² + 6x = 2x² + 26x + 96
