Answer:

4h+2m−4

Step-by-step explanation:

=(2)(m+2h+−2)

=(2)(m)+(2)(2h)+(2)(−2)

=2m+4h−4

=4h+2m−4

The point P(5,1) lies on the curve y=5x. If Q is the point (x,5x), find the slope of the secant line PQ for the following values

sveta [45]

Answer:

5

Step-by-step explanation:

We have been given that the point $P(1,5)$ lies on the curve $y=5x$ . Q is the point $(x,5x)$ . We are asked to find the slope of the secant line $PQ$ for $x=5.1$ .

Let us find y-coordinate corresponding to $x=5.1$ for point P as:

$y=5(5.1)=25.5$

Now, we will use slope formula to find required slope.

$m=\frac{y_2-y_1}{x_2-x_1}$

Let point $(1,5)=(x_1,y_1)$ and point $(5.1,25.5)=(x_2,y_2)$ .

Using these points in slope formula, we will get:

$m_{PQ}=\frac{25.5-5}{5.1-1}=\frac{20.5}{4.1}=5$

Therefore, the slope of the line PQ is 5.

These tables represent a quadratic function with a vertex at (0,3). What is the average rate of change for the interval from X =

Eva8 [605]

Answer:

-19

Step-by-step explanation:

The missing table is shown in the attachment.

Since the quadratic function has vertex at (0,3), its equation is of the form;

$y = a {x}^{2} + 3$

To find the value of 'a' we substitute any other point from the table say (1,2) to get:

$2 = a( {1)}^{2} + 3$

$a = 2 - 3 = - 1$

Hence the function is

$y = - {x}^{2} + 3$

Now

$f(10) = - 100 + 3 = - 97$

$f(9) = - 81 + 3 = - 78$

The average rate of change from x=9 to x=10 is

$\frac{f(10) - f(9)}{10 - 9} = \frac{ - 97 - - 78}{1} = - 19$

You decide to study the effects of smoking, drinking and partying on life satisfaction. To do so, you assign people randomly to

Klio2033 [76]

Answer:

3 factors ; 18 total conditions

Step-by-step explanation:

The study focuses on the 3 factirs which impacts life satisfaction. Thses factors are : Smoking ; Drinking and Partying and they constitute the 3 different factor variables in the study.

For each factor variable, each has a number of different conditions ;

For smoking : 2 conditions (smoking and not smoking)

Drinking : 3 conditions (no alcohol, 1 / day ; several per day)

Partying : 3 conditions (no partying, 1 hour of partying / day, 2 hours of partying / day)

Total number of conditions :

(2 * 3 * 3) = 18 conditions
