Answer:

6.28

Step-by-step explanation:

The length of arc which subtends an angle \alpha at the center of a circle is given by \alpha r where r is the radius of circle.

______________________________

given

the central angle of arc is  120°

\pi = 180\\120 = (\pi /180)* 120\\120 = 2/3\pi

we will use value of \pi as 3.14

r = 3

Length of this arc is

2/3( \pi *3) = 2\pi \\=2*3.14 = 6.28

The length of the arc to the nearest hundredth of unit is 6.28

Is (-1,2) a solution of y=-2x-1
Klio2033 [76]
A solution of a function is where the function hits the x-axis, so if y is any number that is not equal to 0, there is no possible way that point can be a solution. 

Hope this helps!

Solve the equation by using quadratic formula . Show your work! Answer maybe in radical or decimal form .
Lorico [155]

Answer:

x_1=\frac{-2+\sqrt{14}}{2}\approx 0.871,x_2=\frac{-2-\sqrt{14}}{2}\approx-2.871

Step-by-step explanation:

2x^2+4x-5=0

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

x=\frac{-4\pm\sqrt{4^2-4(2)(-5)}}{2(2)}

x=\frac{-4\pm\sqrt{16+40}}{4}

x=\frac{-4\pm\sqrt{56}}{4}

x=\frac{-4\pm2\sqrt{14}}{4}

x=\frac{-2\pm\sqrt{14}}{2}

x_1=\frac{-2+\sqrt{14}}{2}\approx 0.871,x_2=\frac{-2-\sqrt{14}}{2}\approx-2.871

dem82 [27]

Answer:

They'll walk 140.28 miles in 42 hours at that pace.

Step-by-step explanation:

In order to find the distance they can travel at a steady pace, we need to take the pace in wich they intend to travel and multiply it by the time that they intend to travel. In this case their pace is 5 miles every 1.5 hours it means that their pace is 5/1.5 = 3.34 m/h, if they travel for 42 hours they'll travel a distance of:

distance = 3.34*42 = 140.28 miles
