Since f(x) is a polynomial with 3rd degree, then it will have 3 roots (zeroes)
One of them is real and the other two are complex conjugate roots
Since the real root is 4, then
x = 4
Since the complex root is (1 - i), then
The other root will be the conjugate of it (1 + i)
x = (1 - i)
x = (1 + i)
To find f(x) we will multiply the three factors of it
We can get the factors from the zeroes

Subtract 4 from both sides

The first factor is (x - 4)

The second factor is (x - 1 + i)
The third factor is (x - 1 - i)

We will multiply them to find f(x)

Multiply it by (x - 4)

The answer is

Answer:
a) The vertex of the graph is
, b)
, c) The equation of the parabola is
.
Step-by-step explanation:
a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.
The vertex of the graph is
.
b) If we know that
,
and
, then the value of
is:




c) The equation of the parabola is
.
Answer:10×12????=120 i think thats what your aski,
Step-by-step explanation:
Answer:
25%
Step-by-step explanation:
The tip percentage is 100 times the ratio of what you tipped to what you paid.
100 x (1 dollar tip) / (4 dollars paid) = 25%
