Answer: option a. 5.46
Explanation:
The side lengths of the golden rectangle are in the proportion:
1
--------------------
golden number
The golden numbrer is:
1 + √5
-----------
2
So, the ratio is:
1
--------------
1 + √5
---------
2
And, using the properties of the division of fractions, that is equivalent to:
2
-------------
1 + √5
So, since you have thhe given side = 9, you can set the proportion, to find the unknown lenght, s:
2 s
--------- = ---------
1 + √5 9
And you can solve for s:
s = 9 * 2 / (1 + √5) ≈ 18 / (1 + 2.236) = 18 / (3.236) ≈ 5.56.
Which is the option a. 5.56
F(x) = 3x + 2
g(x) = 5x - 10
g(x) - f(x) = (5x - 10) - (3x + 2)
g(x) - f(x) = (5x - 3x) + (-10 - 2)
g(x) - f(x) = 2x - 12
The answer is B.
Answer:
complementary angles sum to 90° 90° - 70° = 20° complementary of 70° is 20°
Answer:
4
Step-by-step explanation:
Answer:
-| y | ≤ | -y |
Step-by-step explanation:
-| y | will be non-positive (may include 0). |-y| will be non-negative (may include 0). A non-positive number is always less than or equal to a non-negative number. They are only equal when both are zero.
