Answer:
degree of polynomial = 5
leading term = 
leading coefficient = 2
constant term = -6
Step-by-step explanation:
(i) The degree of the polynomial = 5. That is, the highest power of x
(ii) Leading term = . This is the term with the highest power of x.
(iii) Leading Coefficient = 2. That is, the coefficient of the leading term ()
(iv) Constant term = -6. This is the term that is independent of x or the term in which x doesn't appear.
Answer:
length = 13
Step-by-step explanation:
Refer to the diagram shown below. It shows a vertical cross-section of the paraboloid through its axis of symmetry.
Let the vertex of the parabola be at the origin. Then its equation is of the form
y = bx²
Because the parabola passes through (18,8), therefore
8 = b(18²)
b = 0.02469
The parabola is y = 0.02469x².
The receiver should be placed at the focal point of the paraboloid for optimal reception.
The y-coordinate of the focus is
a = 1/(4b) = 1/0.098765 = 10.125 in
Answer: The receiver is located at 10.125 inches from the vertex.
