What is the measure of each interior angle of a regular decagon (10 sides)?
bixtya [17]
6)a

if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is
\frac{(n - 2) \times 180}{n}
so the answer will be
\frac{(10 - 2) \times 180 }{10}   = \frac{1440}{10}  = 144
they each measures 144 degrees




good luck

The distance AB rounded to the nearest tenth =
Whitepunk [10]

it gives you the formula, so all you have to do is plug in the coordinates

d =  \sqrt{ {( - 1 + 3)}^{2} +  {( - 1 - 1)}^{2}  }  \\ d =  \sqrt{ {(2)}^{2} +  {( - 2)}^{2}  } \\ d =  \sqrt{ 4 +  4  } \\ d =  \sqrt{8} \\ d = 2 \sqrt{3}  = 3.4641... \\  \\ d = 3.5

A model rocket is launched directly upward at a speed of 50 meters per second from a height of 8 meters. The function f(t)=−4.9t
Gnoma [55]

Answer:

t=\frac{-50 -\sqrt{(50)^2 -4(-4.9)(8)}}{2*(-4.9)}= 10.36

t=\frac{-50 +\sqrt{(50)^2 -4(-4.9)(8)}}{2*(-4.9)}= -0.158

And since the time can't be negative we have that:

t= 10.36 seconds

So the answer for this case would be after 10.36 seconds the rocket will hit the ground

Step-by-step explanation:

For this case we have the function of the height in terms of the time givenby:

h(t) = -4.9t^2 +50 t+8

And we want to known when the rockect hit the ground and for this case we need to solve the equation h=0

-4.9t^2 +50 t+8 =0

And as we can see we have a quadratic equation like this one:

ax^2 +bx+c

Where: a =-4.9 , b =50 c =8

And the general solutions are given by:

x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}

If we replace the values that we have we got:

t=\frac{-50 -\sqrt{(50)^2 -4(-4.9)(8)}}{2*(-4.9)}= 10.36

t=\frac{-50 +\sqrt{(50)^2 -4(-4.9)(8)}}{2*(-4.9)}= -0.158

And since the time can't be negative we have that:

t= 10.36 seconds

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
