The rate of change for this function is 1/2.

In order to find the rate of change, you use the slope equation.

m (slope) = (y2 - y1)/(x2 - x1)

m = (4 - 2)/(9 - 5)

m = 2/4

m = 1/2

vitfil [10]

Answer:

The latest possible date is December, 14th.

Step-by-step explanation:

Notice that the second Friday of December is n+7, where n is the date for the first Friday of December. So, the latest the first Friday, the latest the second. As the weeks have seven days, the first Friday will be between 1st and 7th of each month. So, the latest first Friday will be 7th. Therefore, the latest second Friday will be 14th.

Need to find the number for a

Shalnov [3]

Answer to the first triangle: 15

To solve this we will use the Pythagorean theorem

Pythagorean theorem formula: $a^{2} + b^{2} =c^{2}$

Lets do the first triangle.

17 is the hypotenuse, so its going to replace c in the formula.

8 is the height and it is going to replace a in the formula.

a is what we are trying to find, so our b in the equation is going to be the unknown.

$8^2 + b^2 = 17^2$

$64 + b^2 = 289

$

$b^2 = 289 - 64$

$b^2 = 225$

$\sqrt{b^2} = \sqrt{225}$

$b = 15$

now we know that the missing length in the first triangle (a) is 15
