Remer<br> 1) 5k? + 10k + 6 = 0
IceJOKER [234]

Ignoring the "?" in your question:

5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}

If the "?" is a squared symbol that wasn't caught:

5k^2+10k+6=0

Use the quadratic formula

x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

to get the solutions:

x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}

as you can see, the discriminant is negative, so the equation has no solution.

A circle has a radius of 10. An arc in circle has a central angle of 72 what is the length of the arc
BARSIC [14]

Answer:

4π

Step-by-step explanation:

-A circle subtends a total angle of 360 ° from its center.

-The length of an arc is directly proportional to the angle it subtends from the circle's center.

#The arc's length can therefore be calculated as:

C=\pi D=2\pi r\\\\\therefore C=\frac{72\textdegree}{360\textdegree}\times 2\pi \times 10\\\\=4\pi

Hence, the length of the arc is 4π
