PLEASE HELP!Which of the following statements correctly describes how to tell when a function is positive over a given interval.

Question 5 options:




The functions values are greater than 0 over the interval.


The functions values are less than 0 over the interval.

Answers

Answer: The functions values are greater than 0 over the interval.

Step-by-step explanation:

To tell if a function is positive over a given interval, see if it's below the x-axis or if it's under (since the x-axis represents 0).

If it's below, it's less than zero. If it is above, it's greater than zero.

If the interval is above the x-axis, it's positive (greater), and if it's below, it's negative (less).

Elise is standing on top of a 50 foot building and sees her friend, Molly. If Molly is 30 feet away from the base of the building, what is the angle of depression from Elise to Molly? Elise's eye height is 4.5 feet.

We solve using the Trigonometric function of Tangent

tan x = Opposite/ Adjacent

tan x= 50 ft/30ft

x = arc tan (50 ft/30 ft)

x = 59.036243468°

Approximately = 59.04°

Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient

Answers

conjugate. i hoped that helped

The Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient is P(x) = x³ - x

Let the distinct real zeros of the required polynomial be 0, 1 and -1.

The equivalent factors will be x(x-1)(x+1)

To get the required polynomial, we will take the product of the factors as shown:

P(x) = x(x-1)(x+1)

P(x) = (x+1)(x-1)x

P(x) = x(x²-1)

P(x) = x³ - x

Hence the Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient is P(x) = x³ - x
