Answer:
C. [tex]x^2y[/tex]
Step-by-step explanation:
Given the expression [tex](x^4y^2)^{\frac{1}{2} }\\[/tex]
Using the law of indices;
[tex](a^m)^n = a^{mn}[/tex]
[tex](x^4y^2)^{\frac{1}{2} }\\\\= (x^4)^{\frac{1}{2}} (y^2)^{\frac{1}{2} }\\= x^{4*1/2}y^{2*1/2}\\= x^{2}y[/tex]
Hence the correct answer is [tex]x^2y[/tex]

American Black Ducks migrate a great distance every year. A typical bird will travel 2,739 miles in 33 days. Which of the following best represents this trip with a constant unit rate of travel? 7.4A
Answer:
Rate of travel = 83 miles per day
Step-by-step explanation:
Given:
Total distance = 2,739
Number of days = 33 days
Find:
Rate of travel
Computation:
Rate of travel = Total distance / Number of days
Rate of travel = 2,739 / 33
Rate of travel = 83 miles per day

[tex]f(2.05) = 0.506173[/tex]
[tex]f(2.01)=0.501247[/tex]
[tex]f(2.001) = 0.500125[/tex]

[tex]f(1.99) = 0.498747[/tex]
[tex]f(1.999) = 0.499875[/tex]
[tex]f(1.9999) = 0.499987[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{x^2 - 2x}{x^2 - 4}[/tex]
Solve for f(x) for all given values of x
First, we need to simplify f(x)
[tex]f(x) = \frac{x^2 - 2x}{x^2 - 4}[/tex]
[tex]f(x) = \frac{x(x - 2)}{x^2 - 2^2}[/tex]
[tex]f(x) = \frac{x(x - 2)}{(x- 2)(x + 2)}[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
When [tex]x = 2.1[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(2.1) = \frac{2.1}{2.1 + 2}[/tex]
[tex]f(2.1) = \frac{2.1}{4.1}[/tex]
[tex]f(2.1) = 0.512195[/tex]
When [tex]x = 2.05[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(2.05) = \frac{2.05}{2 + 2.05}[/tex]
[tex]f(2.05) = \frac{2.05}{4.05}[/tex]
[tex]f(2.05) = 0.506173[/tex]
When [tex]x = 2.01[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(2.01)=\frac{2.01}{2.01 +2}[/tex]
[tex]f(2.01)=\frac{2.01}{4.01}[/tex]
[tex]f(2.01)=0.501247[/tex]
When [tex]x = 2.001[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(2.001) = \frac{2.001}{2.001 +2}[/tex]
[tex]f(2.001) = \frac{2.001}{4.001}[/tex]
[tex]f(2.001) = 0.500125[/tex]
When [tex]x = 2.0001[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(2.0001) = \frac{2.0001}{2.0001 + 2}[/tex]
[tex]f(2.0001) = \frac{2.0001}{4.0001}[/tex]
[tex]f(2.0001) = 0.500012[/tex]
When [tex]x = 1.9[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(1.9) = \frac{1.9}{1.9 + 2}[/tex]
[tex]f(1.9) = \frac{1.9}{3.9}[/tex]
[tex]f(1.9) = 0.487179[/tex]
When [tex]x = 1.95[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(1.95) = \frac{1.95}{1.95 + 2}[/tex]
[tex]f(1.95) = \frac{1.95}{3.95}[/tex]
[tex]f(1.95) = 0.493671[/tex]
When [tex]x = 1.99[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(1.99) = \frac{1.99}{1.99 + 2}[/tex]
[tex]f(1.99) = \frac{1.99}{3.99}[/tex]
[tex]f(1.99) = 0.498747[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
When [tex]x = 1.999[/tex]
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(1.999) = \frac{1.999}{1.999 + 2}[/tex]
[tex]f(1.999) = \frac{1.999}{3.999}[/tex]
[tex]f(1.999) = 0.499875[/tex]
When x = 1.9999
[tex]f(x) = \frac{x}{x + 2}[/tex]
[tex]f(1.9999) = \frac{1.9999}{1.9999 + 2}[/tex]
[tex]f(1.9999) = \frac{1.9999}{3.9999}[/tex]
[tex]f(1.9999) = 0.499987[/tex]
Note that all values of f(x) are approximated to 6 decimal places
In one problem, he gave her a store receipt that listed 72 identical items, each the
same price, for a total cost of
$ * 67.9*
Bryn's Grandpa covered the first and last digits of the total price on the receipt
with stars.
Determine the values of the digits that Bryn's Grandpa covered.
Answer:
The first covered digit = x = 3
The last covered digit = y = 2
The total price on the receipt = $367.92
Step-by-step explanation:
Given data:
total cost = $ * 67.9*
First we check for the multiples of 72
9 × 8 = 72
Let
the first covered digit be denoted by x
the last covered digit be denoted by y
Solution
First we find the last covered digit
If a number should be divisible by 8,
It must be a multiple of 8
From the given price:
The last 3 digits = 79*
number in multiples of 8
7.9* = 7.20 + 0.64+ 0.08
7.9* = 7.92
Therefore, the last two digit is 2.
Next We find the first covered digit.
If a number is divisible by 9, it is a multiple of 9
The first digit = x would be determined as:
= x + 6 + 7 + 9 + 2
= x + 24
= x + 24
multiple of 9 nearer to 24 = 27
27 = x + 24
x = 27 - 24
x = 3.

When the output value of a real-valued function, f(x), is equal to f(-x), for all values of x inside the domain of f, the function is said to be an even function.
It is claimed that a real-valued function f(x) is an odd function when, for all values of x in the domain of f, the output value of f(-x) is equal to the negative of f(x).
Given:
As, we know the first graph graph of an odd function is at the same distance from the origin but in opposite directions and, graph of an even function remains the same after reflection about the y-axis.
So, The polynomial function for this graph is of odd degree and the leading coefficient is negative.
and, The polynomial function for this graph is of even degree and the leading coefficient is negative.

Is the relationship between the number of tickets sold and the number of hours proportional? If so, how many tickets were sold in 8 hours?
Answer:
640 tickets.
Step-by-step explanation:
8hours × 80 = 640
There are 640 tickets are sold in 8 hours.
What is Proportional?
The equality between two ratio is called Proportional.
Given that;
Number of hours for selling number of tickets.
Since, To check the relationship is proportional or not, we check the equality between two given ratio.
Hence, The ratio are;
Number of hours : Number of Tickets
= 3 : 240 : : 5 : 400
It can be solve as;
= 3/240 = 5/400
= 1/80 = 1/80
= 1:80 : : 1:80
Thus, The given relationship between the number of tickets sold and the number of hours is proportional.
Now, Let number of tickets in 8 hours = x
Then, By definition of proportional we get;
⇒ 3 : 240 :: 8 : x
Solve the proportional as;
⇒ 3/240 = 8/x
⇒ x = 8 × 80
⇒ x = 640
So, There are 640 tickets are sold in 8 hours.
