The initial height of the tree = 7 ft
Each year the tree grows 6 in. 6 in = 6 / 12 = 0.5 ft
So the tree grows 0.5 ft every year.
After x years, the tree would have grown extra = 0.5*x =0.5x
So the height of the tree would be = Initial height + extra height grown
= 7 + 0.5x
h = 7 + 0.5x
Model is h = 7 + 0.5x,
where h = height of the tree in feet after x years.
Hope this explains it.
Use the cosine law to answer the question which can be expressed as,
c² = a² + b² -2ab(cos C)
where c is the side opposite to angle C and a and b are the sides adjacent to the angle. Substituting the given values,
c² = 33² + 37² - (2)(33)(37)(cos 120°) = 3679
The value of c is 60.65. Therefore, the length of the third side is approximately 60.65 units.
Answer:
D. None of the above.
Step-by-step explanation:
Supplementary angles must add up to 180 degrees.
Complementary angles must add up to 90 degrees.
Vertical angles are opposite of each other.
Hope this helps!
If not, I am sorry.
Answer:
80 questions
Step-by-step explanation:
100%/20%=5%
5×16=80
Therefore, there are 80 questions in the test.
Since all sides of a square are the same you can square the side length you are given.
A = (8.2)x(8.2) or 8.2^2
That would give you 67.24
