The simplified form of the expression [tex]x^2 - 9 / x^2 - 3x[/tex] is:
[tex](x - 3)(x + 3) / x^2 - 3x[/tex]
To simplify the expression [tex]x^2 - 9 / x^2 - 3x[/tex], we can factor the numerator and denominator if possible and cancel out any common factors.
First, let's factor the numerator and denominator:
[tex]x^2 - 9[/tex] can be factored as (x - 3)(x + 3).
[tex]x^2 - 3x[/tex] cannot be factored further.
Now, we can rewrite the expression with the factored form:
[tex](x - 3)(x + 3) / x^2 - 3x[/tex]
Next, we can look for any common factors between the numerator and denominator that can be canceled out. In this case, there are no common factors that can be canceled out.
Therefore, the simplified form of the expression [tex]x^2 - 9 / x^2 - 3x[/tex] is:
[tex](x - 3)(x + 3) / x^2 - 3x[/tex]

Answer:
the second one
Step-by-step explanation:
angles k and p are supplementary and the measure of k is twice that of p, find both angles in degrees
Answer:
p=60 and k=120
Step-by-step explanation:
So, with supplementary angles, there is a max of 180 degrees (because it is half of a circle.) With this information, we can make an equation. Let's make it.
If the measure of k is twice of p, then k=2p
Equation= 2p+p=180
Now let's isolate p and find out what it is!
2p+p=3p so...
3p=180
Now let's divide 3 on both sides.
That would equal...
p=60
That means p=60 for sure. However, since k is twice of p, we need to double p to find out what k is.
60 x 2=120
Final answer= p=60 k=120
Hope this helped!! If you have any questions, make sure to write them in the comments!
Answer:
k = 120
p = 60
Step-by-step explanation:
k = p2
p+p2 = 180
p3 = 180
p3/3 180/3
p = 60
k = 60 × 2
k = 120

Answer:
a. Area = 1,017.36 cm²; Circumference = 113.04 cm
b. Area
c. Circumference
Step-by-step explanation:
Given:
Radius (r) = 18 cm
π = 3.14
a. Area of the mirror = area of circle = πr²
Plug in the values
Area = 3.14*18²
Area = 1,017.36 cm²
Circumference = 2πr
Circumference = 2*3.14*18
Circumference = 113.04 cm
b. The area of the glass would be used in finding the amount of glass needed caused it's the surface of the glass that is to be replaced.
c. The silver wire would be placed around the mirror, therefore, it is the circumference that would be needed in finding the amount of wire needed since the circumference is the perimeter round the mirror.

Step-by-step explanation:
Multiply the original value by 1.035 to get your answer.
Let x be the initial salary
x=13.75
Let y be the new salary
y=x+x(3.5%)
y=13.75+13.75(0.035)
y=13.75+0.48=14.23
New hourly salary=14.23$

Answer:
The area of the rectangle is 4 sq yards.
Step-by-step explanation:
Given that,
The length of the rectangle, [tex]L=\dfrac{2}{13}\ yards[/tex]
The breadth of the rectangle, B = 26 yards
We need to find the area of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
[tex]A=\dfrac{2}{13}\times 26\\\\A=2\times 2\\\\A=4\ yd^2[/tex]
So, the area of the rectangle is 4 sq yards.
what is the average rate of change of f(x) = (x + 3)2 − 2
Answer:
When we have a function f(x), the average rate of change in the interval (a, b) is:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
In this case, we have the function:
f(x) = (x + 3)^2 - 2
(but we do not have the interval, and I couldn't find the complete question online)
So if for example, we have the interval (2, 4)
The average rate of change will be:
[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]
If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).
Such that the rate of change, in this case, will be:
f'(x) = df/dx
For a function like:
g(x) = x^n + c
g'(x) = n*x^(n - 1)
And for:
h(x) = k( g(x))
h'(x) = k'(g(x))*g'(x)
So here we can write our function as:
f(x) = k(g(x)) = (x + 3)^2 - 2
where:
g(x) = x + 3
k(x) = x^2 - 2
Then:
f'(x) = 2*(x + 3)*1 = 2*x + 6
That is the rate of change as a function of x (but is not an "average" rate of change)

The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. a. Which form of the hypotheses should be used to test the manager's claim? H 0: less than or equal to $600 H a: greater than $600 b. When H 0 cannot be rejected, can we conclude that the manager's claim is wrong? No c. When H 0 can be rejected, can we conclude that the manager's claim is wrong? Yes
Answer:
H0 : μ ≤ 600
H1 : μ > 600
B.) NO
C.) YES
Step-by-step explanation:
Here, the null hypothesis is the claim, that mean guest bill is $600 or less ; The alternative will be the opposite of the null which is the counterclaim. This ubstge accountants assertion that guest bill has been increasing
Hence,
H0 : μ ≤ 600
H1 : μ > 600
When the null cannot be rejected, that means there is no sufficient evidence to support the alternative hypothesis, Hence, we stick with the manager's claim
When H0 can be rejected, then there is sufficient evidence to support, the accountant's claim. Thus, we go with the accountant's claim and conclude that the manager is wrong.
