A polygon is regular if each of it's sides has the same length. find the perimeter of the regular polygon.

KiRa [710]

Answer:

I would assume you're supposed to solve for x and multiply that by 8 for the perimeter. Like I said in the comment, I'm not a math major.

Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.

Rudik [331]

Step-by-step explanation:

Given

The function is $f(x)=x+4$

for $x_2>x_1$ , we will check the values of $f(x_1)$ and $f(x_2)$

Take 3 and 4

$f(4)=4+4\\f(4)=8$

Similarly,

$f(3)=3+4\\f(3)=7$

Thus, $f(4)>f(3)$

Also, $f'(x)$ is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.

If a stone is thrown down at 170 feet per second from a height of 1,020 feet, its height after t seconds is given by

andreyandreev [35.5K]

Step-by-step explanation:

It is given that,

Initial speed of the stone, u = 170 ft/s

It is thrown down from a height of 1020 feet.

We need to its height after t seconds. It can be calculated using second equation of kinematics as follows :

$h=ut-\dfrac{1}{2}gt^2+h_0$

h₀ is initial height, u = -170 ft/s as the stone is throwing down and g = -32ft/s²

Putting values, we get :

$h=-170t-\dfrac{1}{2}\times 32t^2+1020\\\\h=-16t^2-170t+1020$
