Answers
First, I'm going to separate factor the expression inside of the square root.
sqrt[ (2/18) * (x^5) ]
sqrt[ (1/9) * (x^5) ]
We can take the square root of 1/9 easily, because 1 and 9 are both perfect squares. The square root of 1/9 is 1/3.
Looking at the x^5, we can separate it into x^2 * x^2 * x^1. The square root of x^2 is x. So, we now also have an x^2 on the outside because there are two x^2s in our expanded form.
ANSWER: (x^2 * sqrt(x)) / 3

twelve people enter a contest. prizes will be given for first second and third place. how many ways can the prizes be given
Answers
Answer:
1320 ways
Step-by-step explanation:
Number of contestants = 12
Positions that are n be awarded = First, Second, Third
Number of contestants who could be first = 12 (all 12 contestants)
Number of contestants who could be second = 11 (all 12 contestants - first)
Number of contestants who could be third = 10 (all 12 contestants - first and second )
The number of ways prices can be given :
(1st * 2nd * 3rd) = 12 * 11 * 10 = 1320 ways

Answer:
I believe the answer is d = 32
Step-by-step explanation:
You should isolate the radical, then raise each side of the equation to the power of its index.

Answer:
d = 32
Step-by-step explanation:
Add 4, then square, and solve the resulting linear equation.
√(7d +1) = 15
7d +1 = 225 . . . . . . square both sides
7d = 224 . . . . . . . . subtract 1

=FV(4.5%/12,30*12,-150,0)$113,907.92$54,000$59,907.92Step-by-step explanation:
We have used the formula shown in Go.ogle Sheets to give the results shown. (We presume Excel has a similar function.)
The result is that the future value of the investment is $113,907.92.
The amount deposited is ($150/mo)(12 mo/yr)(30 yr) = $54,000.
The interest earned is the difference: $113,907.92 -54,000 = $59,907.92.

Boat A leaves a dock headed due east at 2:00PM traveling at a speed of 9 mi/hr. At the same time, Boat B leaves the same dock traveling due south at a speed of 15 mi/hr. Find an equation that represents the distance d in miles between the boats and any time t in hours.
Answers
Answer: [tex]17.5t[/tex]
Step-by-step explanation:
Given
Speed of boat A is [tex]v_a=9\ mi/hr[/tex]
Speed of boat B is [tex]v_b=15\ mi/hr[/tex]
Both are moving perpendicular to each other
Distance traveled by Boat A [tex]x_a=9t[/tex]
Distance traveled by Boat B [tex]x_b=15t[/tex]
Distance between them is given by Pythagoras theorem
[tex]\Rightarrow d^2=(x_a)^2+(x_b)^2\\\\\Rightarrow d^2=(9t)^2+(15t)^2\\\\\Rightarrow d=\sqrt{(9t)^2+(15t)^2}\\\\\Rightarrow d=\sqrt{81t^2+225t^2}\\\\\Rightarrow d=\sqrt{306t^2}\\\\\Rightarrow d=17.49t\approx 17.5t\ \text{miles}[/tex]
Distance between them is [tex]17.5t[/tex]
A team of 22 soccer players needs to choose 3 players to fill water bottles. How many different groups can be made?
Answers
Answer:
1540
Step-by-step explanation:
To figure out the answer you must compute 22 choose 3. To compute this, we can plug the values into the Combination formula, which goes like this:
[tex]\frac{n!}{r!(n-r)!}[/tex], where n is the sample size, and r is the amount being chosen. In this case, n is equal to the total 22 players, and r is the 3 players being chosen to fill the bottles. Plugging the values in, we have the answer as
[tex]\frac{22!}{3!(22-3)!}[/tex]. 22 minus 3 simplifies to 19 factorial, and we can expand 22 factorial out from the numerator.
[tex]\frac{22(21)(20)(19!)}{3!(19!)}[/tex]
We can get rid of the 19 factorial from both the numerator and the denominator, and we are left with
[tex]\frac{22(21)(20)}{3(2)}[/tex]
We can cancel out the 3 with the 3 in 21, and we can cancel out the 2 with the 2 in 20. We are left with
[tex]22(7)(10)[/tex]

Step-by-step explanation:

Answer:
$1487.50
Step-by-step explanation:
The amount of interest due is ...
I = Prt
where P is the loan amount, r is the annual rate, and t is the number of years. Here, t = 6 months = 1/2 year, so the interest due is ...
I = $1400×0.125×1/2 = $87.50
The total amount due is the sum of the loan amount and the interest:
due = $1400 +87.50 = $1487.50
The total amount due after 60 months is $1487.50.

Step-by-step explanation:
The square root function's graph is graph (b). This makes logical sense, because, when taking the square root (the principal root in particular), a general rule is that both the input and the output must be positive. Moreover, if one were to create a table of values to find points on the graph of the function, each of the points can be found on graph (b).
