Step-by-step explanation:
tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.
Therefore 1.6m / (2m + x) = 1/√3
By cross multiplication, 1.6√3 = 2 + x.
Hence, x ≈ 0.77m.
Answer:
4
Step-by-step explanation:
3x-12=24
-12 to both sides
3x-12-12=24-12
3x=12
3x/3=12/3x
x=4
Answer:
100 quarters = 2500 cents = $25
500 dimes = 5000 cents = $50
total = $75
Step-by-step explanation:
Given:
Zero: 2, multiplicity: 3
Zero: 0, multiplicity: 2
Degree: 5
Leading coefficient = 1
To find:
The polynomial function.
Solution:
The general form of a polynomial is
where, a is a constant, are zeroes with multiplicity .
Using the given information and the general form of a polynomial, we get
Leading coefficient is 1, so the value of a is also 1.
Therefore, the required polynomial is .
