Answer:

  about 19.92 meters

Step-by-step explanation:

The circumference is ...

  C = πd

  72 m = πd . . . . . for outer diameter d

  d = (72 m)/π

The inner diameter is 3 meters shorter, so is ...

  inner diameter = (72/π) m - 3 m ≈ 19.92 m

find the equation of the line passes through the point (-1,2) and making an angle of 45° with the line x-y+1=0​
Vlad1618 [11]

Answer:

Step-by-step explanation:

line given is x-y+1= 0

you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis

x-y+1 =0 subtract x and 1 from both sides of the equation

-y = -x-1 multiply both sides by -1

y = x+1 so the slope of this line is 1 and the y-intercept is 1

If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2

Use the factor theorem to determine which of the following is a factor of f(x)=x^3+5x2-15x+9
patriot [66]

x+2

Step-by-step explanation:

x+2

If x = –2 is a zero, then x + 2 = 0, so x + 2 is a factor. Similarly, if x = 1/3 is a zero, then x – 1/3 = 0, so x – 1/3 is a factor. By giving me two of the zeroes, they have also given me two factors: x + 2 and x – 1/3.
