An open circle means not equal to. So, if your equation is x < 4, You would put an OPEN circle at four because it can't equal four.
Let's look at the math; half a disk takes 40 seconds to rip, and two halves make a whole, so 40 + 40 = 80 and that's your answer
Answer:
Third Choice, 1774.67π cm³
Step-by-step explanation:
Volume=(4/3)πr³
=(4/3)π×11³
=(4/3)π×1331
=1774.67π cm³
A is the correct answer.
Point Slope Form: y - y₁ = m(x - x₁)
m = slope ⇒ -4/7
Coordinate: (-1 , 4)
x₁ y₁
All you have to do is plug in all of the information above into the formula.
y - 4 = -4/7(x +1)
