The percentage of obese children aged 12-19 years in the United States is approximatelyP(t) = 0.04t + 4.6 if 0 ≤ t < 10−0.010
Art [367]

Answer:

4.8% of of obese children aged 12-19 at the beginning of 1975.

9.15% of obese children aged 12-19 at the beggining of 1986

13.94% of obese children aged 12-19 at the beggining of 1995

Step-by-step explanation:

The percentage of obese children aged 12-19 years in the United States is given by the following piecewise function:

P(t) = \left \{ {{0.04t + 4.6, 0 \leq t < 10}\atop {-0.01005t^{2} + 0.945t - 3.4, 10 \leq t < 30}} \right.

In which t is measured in years.

What was the percentage of obese children aged 12-19 at the beginning of 1975?

This is the value of P when t = 5, so P(5).

For P(5), we apply the first definition of the piecewise function.

P(5) = 0.04(5) + 4.6 = 0.2 + 4.6 = 4.8

At the beginning of 1986?

The value of P when t = 16, so P(16).

For P(16), we apply the second definition of the piecewise function.

P(16) = -0.01005(16)^{2} + 0.945(16) - 3.4 = 9.15

At the beginning of 1995?

The value of P when t = 25, so P(25).]

For P(25), we apply the second definition of the piecewise function.

P(16) = -0.01005(25)^{2} + 0.945(25) - 3.4 = 13.94

The graph of the function f(x) = (x – 4)(x + 1) is shown below.
marysya [2.9K]

Answer:

The function is decreasing for all real values of x where  x < 1.5 ⇒ 4th

Step-by-step explanation:

* Lets revise some points about the quadratic function

- The quadratic represented graphically by a parabola

- If the vertex of the parabola is point (h , k), then

- Point (h , k) is the minimum point of the function if the parabola opens

   upward

- Point (h , k) is the maximum point of the function if the parabola opens

   downward

- <em>If point (h , k) is a minimum point, then the function is decreasing</em>

<em>   for all values of x smaller than h and increasing for all values of x </em>

<em>   greater than h</em>

- If point (h , k) is a maximum point, then the function is increasing for

   all values of x smaller than h and decreasing for all values of x greater

   than h

* Now lets solve the problem

- From the attached graph and the given

∵ The parabola represents a quadratic function

∵ The parabola opens upward

∴ Its vertex is minimum

- <em>Lets use the bold point above</em>

∵ The coordinates of the vertex are (1.75 , -6.2)

∴ The function is decreasing for all values of x less than 1.75

* The function is decreasing for all real vales of x where x < 1.75

∴ The function is increasing for all values of x greater than 1.75

* The function is increasing for all real vales of x where x > 1.75

- <em>From the answer there is only one statement true</em>

- The statement is:

  The function is decreasing for all real values of x where  x < 1.5,

   because the function is decreasing for all real values of x where

    x < 1.75 and 1.5 is smaller than 1.75

* The function is decreasing for all real values of x where  x < 1.5
