Step-by-step explanation:
We have to organize the given polynomials from the least to greatest based on their degrees.
A). x + 2xyz
Here xyz =
Power of x is = 1
Power of y = 1
and power of z = 1
So degree of (x + xyz) will be degree of the highest degree term = 1 + 1 + 1 = 3
B). 9x³y²
Degree of this term = power of x + power of y = 3 + 2 = 5
C). 18x²+ 5ab - 6y
Degree of the polynomial = Highest degree of the variable x = 2
D).
Degree of highest degree term = 4
So sequence of the polynomials based on their degrees will be
C - A - D - B [From lowest to highest]
Answer:
77 m (nearest metre)
Step-by-step explanation:
<u>Angle of Elevation</u>
If a person stands at a point and looks up at an object, the angle between their <u>horizontal line of sight</u> and the <u>object</u> is called the angle of elevation.
To find how tall the flagpole is, model as a right triangle and solve using the tan trigonometric ratio.
<u>Tan trigonometric ratio</u>
where:
is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
Given information:
- Person height = 1.6 m
- Horizontal distance (from person to flagpole) = 35 m
- Angle of elevation = 65°
Therefore:
- O = height of flagpole <u>less</u> height of person
- A = 35 m
As the person is 1.6 m tall, we model the line of sight as 1.6 m <u>above ground level</u>. Therefore, when calculating the height of the flagpole, we will need to add the height of the person to the value found using the trig ratio.
Substitute the given values into the formula and solve for O:
Therefore the height of the flagpole is:
