Find the third degree function that has zeros 7 and −11i, and a value of 663 when x=10.
slega [8]

Answer:

y = x^3 - 7x^2 + 121x + 847

Step-by-step explanation:

If -11i is a zero, its conjugate also is a zero, so the zeros are:

7, 11i and -11i.

So we can write the third degree function as:

y = a(x-7)(x-11i)(x+11i)

y = a(x-7)(x^2+121)

If the function has a value of 663 when x = 10, we have:

663 = a(10-7)(10^2+121)

663 = a(3)(221)

a = 663/663 = 1

So the function is:

y = (x-7)(x^2+121)

y = x^3 - 7x^2 + 121x - 847

For the following pair of variables, state the units that might be used to measure each variable. Then state whether you believe
AfilCa [17]

Answer:

The correct answer is:

There is a positive correlation because women's weight tend to increase when height increases (D)

Step-by-step explanation:

The units that might be used to measure each variable are:

Height : meter (m) or foot (plural, feet) (Ft.)

weight : kilograms (kg) or Pounds (lb)

A positive correlation is said to occur between two variables when they both move in the same direction, that is, when they both increase or decrease, while a negative correlation occurs when the movement is not in tandem, i.e, as one increases, the other decreases. The relationship between height and weight is a positive correlation because, an increase in height, which is mainly as a result of elongation of bones, leads to an accumulated increase in total body mass, which in turn increases the body weight.
