Which expression is equivalent to ?
xy^2/9?
Answer: [tex]x\sqrt[9]{y^{2} }[/tex]
Step-by-step explanation: For all expressions in the form [tex]x^{\frac{a}{b}[/tex] , the expression is equal to [tex]\sqrt[b]{x^a}[/tex]. The denominator in a fractional exponent is the type of root it is. For example, [tex]x^\frac{1}{3}[/tex] is going to be the cubed root, or the
3rd root of x ([tex]\sqrt[3]{x}[/tex]). The numerator is what power x is raised to. For example, [tex]x^\frac{3}{2}[/tex] is going to be [tex]\sqrt{x^3}[/tex].
In fractional exponents, the square root only takes the form of the variable it is assigned to. What does that mean? Well, for [tex]xy^\frac{2}{9}[/tex], the square root only applies to the y. The x is considered a constant and can be moved out. Thus, we get [tex]x\sqrt[9]{y^2}[/tex].
A moving company’s moving rates can be represented by the function f(x) = 3x + 400, where x is the number of miles for the move.
Another moving company’s rates can be represented by the function g(x) = 5x + 200.
Which function represents the difference between the moving companies' rates, h(x) = f(x) – g(x)?
The difference betweeh the two companies' moving rates is:
(f - g)(x) = -2x + 200
Which function represents the difference between the moving companies' rates?Here we have two functions:
f(x) = 3x + 400
g(x) = 5x + 200
These functions represent the moving rates for two different companies.
If we want to find the difference between the moving rates, we just need to take the difference between the functions:
(f - g)(x) = f(x) - g(x) = (3x + 400) - (5x + 200) = -2x + 200
So the difference betweeh the two companies' moving rates is:
(f - g)(x) = -2x + 200

Naomi was asked to show that point DDD is equidistant from points AAA and CCC.
A line bisector is a straight line that divides a given line into two equal parts. Thus the following steps are required by Naomi to show that point D is equidistant from points A and C.
BD ⊥ AC (given)
BD = 3 units, and AC = 8 units.
BD is the perpendicular bisector of segment AC (given)
Thus,
<BDA ≅ <BDC (right angles formed by a perpendicular bisector)
AD ≅ DC (equal parts of a bisected line)
AD ≅ DC = 4 units
Thus joining points B to A, and B to C,
BA ≅ BC.
So that applying Pythagoras theorem to ΔABD, we have:
[tex]/hyp/^{2}[/tex] = [tex]Adj 1^{2}[/tex] + [tex]Adj 2^{2}[/tex]
[tex]AB^{2}[/tex] = [tex]3^{2}[/tex] + [tex]4^{2}[/tex]

AB = 5 units
So that,

Divide name and write the answer under it.
look for another number that can divide those answers you got. but they aren't no numbers that can divide them without remainders anymore, so you divide 2 by 2 and write down 1 and just write down the 3 back .

Air America has a policy of booking as many as 15 persons on an airplane that can seat only 14. (Past studies have revealed that only 85% of the booked passengers actually arrive for the flight.) Find the probability that if Air America books 15 persons, there will be enough seats will be available.
The probability that if Air America books 15 persons, there will be enough seats available is 0.913.
How to determine the probability?First of all, we would determine the probability that if Air America books 15 persons, there won't be enough seats available by using binomial distribution:
P(x = 15) = 0.85¹⁵
P(x = 15) = 0.087.
