Can someone plz help me with number 17 plz show work bc I’m not understanding this plzz and thank you

39.3 feet

explanation:

- because you need to find the length of an arc, you should think about circumference. the formula for that is 2πr, where r is the length of the circle's radius.

- you don't need the whole circumference, though, so you'll need a fraction (in this case, it's 225/360, because 225° is the measure of the arc's angle and 360° is the measure of a full circle's rotation)

- multiply the circumference by this fraction to get the length of the arc.

work:

enter 12.5π into a calculator and it's about 39.3 after being rounded to the nearest tenth.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

p = 6s
