What is leading coefficient of the function f(x) = 3x5 + 6x4 − x − 3?
2 answers:
Answer:
(A) 3
Step-by-step explanation:
The given function is:
Now, The leading term is the term containing the highest power of the variable and the leading coefficient is the coefficient of the leading term.
Thus, The leading term of the given function is , therefore the leading coefficient is the coefficient of this leading term that is 3.
Hence,, option A is correct.

Applying the trigonometry ratio, TOA, the measurement that is closest to the height of the tree in feet is: D. 21
Recall:
Trigonometry ratios can be applied to solve any right triangle for missing side lengths or angles. They are denoted with the acronym, SOH CAH TOA.
Using trigonometry ratio, TOA, find the length of the side of the tree in the bigger triangle as follows:
tan 60 = x/9
x = tan 60 × 9
x = 15.6 ft
Height of the tree = 15.6 + 5.2 = 20.8 ft.
- In conclusion, applying the trigonometry ratio, TOA, the measurement that is closest to the height of the tree in feet is: D. 21
