Seven new employees, two of whom are married to each other, are to be assigned seven desks that are lined up in a row. If the assignment of employees to desks is made randomly, what is the probability that the married couple will have nonadjacent desks
then, the surface area of the sphere shown in the image is: 256π sq. units!
step-by-step explanation:
the lateral surface area of a sphere is 2πrh where h=2r.
then:
surface area = 4πr^2.
in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!
then, the surface area of the sphere shown in the image is: 256π sq. units!
answer: idk
step-by-step explanation:
1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).
in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.
then
f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)
= -(2x² +3x -2)(x -3)
= -(2x³ -3x² -11x +6)
f(x) = -2x³ +3x² +11x -6
2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.
3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
