<h3>What is Quadratic equation ?</h3>A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic equation is y = a + bx + c, where a, b, and c are numbers and a cannot be 0
P(A) = 0.006 - 0.02a + 120
123 = 0.006- 0.02a + 120
0=0.006 - 0.02a - 3
you can use the quadratic equation formula to solve for the man's age.
A = (-b ± () ) / (2a)
A = (0.02 ± / (2*0.006)
A = (0.02 ± ) / 0.012
A = 9 , -5.67

Answer:
B. 2 meters.
Explanation:
To rotate the capstan a certain amount of torque is required, and if each sailor applies a force at a distance
from the center, then for two sailors the total torque will be
;
therefore, for one sailor to apply the same torque it must be that the torque he applies must be equal to the torque that the two sailors applied:
which gives
.
and since ,
which is choice B.
