To answer this item, we use dimensional analysis and conversion factor, 1 revolution is equal to 2π rad. Using the concept and the given,
n = (14.2 revolutions / 8 seconds)(2π rad/1 rev)
n = 11.15 rad/s
Thus, the angular velocity is equal to 11.15 rad/s.
the ladder leaning against the wall has slope 3
Answer:
0.45 lbs
Step-by-step explanation:
2 1/4 can be converted to the decimal: 2.25
2.25÷5 is how you will set this problem up, because 2.25 lbs of candy is being divided amongst 5 people.
0.45 lbs is the answer
Completing the square is a method used to solve a quadratic equation by changing the shape of the equation so that the left side is a perfect square trinomial.
The following equation makes more sense to solve it complete squares:
x² + 20x = 52
We have then:
x² + 20x + (10) ^ 2 = 52 + 100
(x + 10) ² = 152
Answer:
The most sense to solve by completing the square is for:
B) x² + 20x = 52
