The expression can be simplified to [tex]625 \times (uv)^4.[/tex]
To rewrite the expression (-5uv)(-5uv)(-5uv)(-5uv) using the properties of exponents, you can consolidate it using the exponent rule that states when you multiply numbers with the same base, you add the exponents. In this case, the base is -5uv, and you are multiplying it four times, so the exponent is 4:
[tex](-5uv)(-5uv)(-5uv)(-5uv) = (-5uv)^4[/tex]
Now, you can simplify further by applying the rule for raising a power to a power, which states that when you raise an exponentiated term to another exponent, you multiply the exponents:
[tex](-5uv)^4 = -5^4 \times (uv)^4[/tex]
-5^4 means -5 multiplied by itself four times:
[tex]-5^4 = -5 \times -5 \times -5 \times -5 = 625[/tex]
So, the expression can be simplified to:
[tex]625 \times (uv)^4[/tex]
This is the expression rewritten using the properties of exponents.

The property tax on a $160,000 home is $3,840. At this rate, what is the property tax on a home appraised at $260,000? $
Answer:
$6240
Step-by-step explanation:
Find the rate by dividing property tax by the appraisal value.
[tex]\frac{3840}{160000}=0.024[/tex]
Now multiply the appraised value by this rate to find the property tax.
[tex]260000*0.024=6240[/tex]
The property tax on a home appraised at $260,000 is $6,240.
Explanation:To find the property tax on a home appraised at $260,000, we can set up a proportion using the given information. The property tax on a $160,000 home is $3,840, so we have:
$160,000 : $3,840 = $260,000 : x
Using cross-multiplication, we can solve for x:
x = ($260,000 * $3,840) / $160,000

A 52-inch pipe is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece.
Answer:
The length of the shorter piece is 13 inches
Step-by-step explanation:
Let's represent the longer piece of pipe with the variable L and the shorter piece of pipe with variable S.
Since the pipe is going to be the length of L and S together, we can make this equation:
L+S=52
Also we know that the longer piece is three times the shorter piece or
L=3S
Substitute the second equation into the first equation.
L+S=52
3S+S=52
4S=52
Divide both sides by 4
4S/4=52/4
S=13 inches
The length of the shorter piece is 13 inches....
To find the length of longer piece, put the value S=13 in L=3S
L=3S
L=3(13)
L=39 inches
The length of the longer piece is 39 inches....

Factor completely 3x4 − 30x3 + 75x2. 3(x − 5)2 3x2(x − 5)2 3x2(x2 − 10x + 25) 3x2(x + 5)(x − 5)
Answer:
The complete factorization is 3x² (x - 5)² ⇒ 2nd answer
Step-by-step explanation:
* Lets revise how to factorize a trinomial
- Find the greatest common factor of the coefficients of the three terms
∵ The trinomial is 3x^4 - 30x³ + 75x²
- The greatest common factor of 3 , 30 , 75 is 3
∵ 3 ÷ 3 = 1
∵ 30 ÷ 3 = 10
∵ 75 ÷ 3 = 25
∴ 3x^4 - 30x³ + 75x² = 3(x^4 - 10x³ + 25x²)
- Now lets find the greatest common factor of the variable x
∵ x² is the greatest common factor of the three terms
∵ x^4 ÷ x² = x²
∵ 10x³ ÷ x² = 10x
∵ 25x² ÷ x² = 25
∴ 3(x^4 - 10x³ + 25x²) = 3x² (x² - 10x + 25)
- Lets factorize (x² - 10x + 25)
∵ √x² = x
∵ √25 = 5
∵ 2 × 5 × x = 10x
∴ x² - 10x + 25 is a completing square
∴ (x² - 10x + 25) = (x - 5)²
∴ 3x² (x² - 10x + 25) = 3x² (x - 5)²
* The complete factorization is 3x² (x - 5)²
Answer:
3x^2 (x-5)^2
Step-by-step explanation:
3x^4 − 30x^3 + 75x^2
We can factor out a 3x^2 from each term
3x^2 (x^2 -10x +25)
The term inside the parentheses can be factored
What 2 numbers multiply to 25 and add to -10
-5*-5 = 25
-5+-5 = -10
3x^2 (x-5) (x-5)
3x^2 (x-5)^2

3(b+4)+8=-3 as a linear equation.
For this case we have the following equation:
[tex]3 (b + 4) + 8 = -3[/tex]

[tex]3b + 12 + 8 = -3[/tex]
We add similar terms to the left side of the equation:
[tex]3b + 20 = -3[/tex]
Subtracting 20 from both sides of the equation:
[tex]3b = -3-20\\3b = -23[/tex]
Dividing between 3 on both sides of the equation:
[tex]b = - \frac {23} {3}[/tex]

Kasey has a job that pays $865 per week. How much is withheld from each paycheck for Social Security?
Kasey has $53.63 withheld from her weekly paycheck of $865 for Social Security, which is calculated by multiplying her weekly pay by the Social Security tax rate of 6.2%.
Explanation:The question asks us to calculate how much is withheld from Kasey's paycheck for Social Security.
With a weekly pay of $865, we need to find 6.2% of that amount since that is the percentage deducted for Social Security taxes.
To find this amount, we multiply $865 by 0.062.
Calculation: $865 × 0.062 = $53.63
Therefore, $53.63 is withheld from Kasey's paycheck each week for Social Security.

30/24 = 5/4
40/32 = 5/4
c)
12/4 = 3
15/5 = 3
24/6 = 4
d)
4/3 = 4/3
9/6 = 3/2
12/16 = 3/4
So, Option B is correct.
Answer: Second Option
Step-by-step explanation:
It is said that two variables a and b are propocionales if when b increases then a increases in a constant rate.
That is, a and b are proportional if the quotient between b and a is always equal to a constant k.
[tex]\frac{b}{a}=k[/tex]
To know which of the tables shows a proportional relationship identify in which of the tables the division of b between a always is constant
You can verify that the table where the quotient of b enters a is always constant is in the second table
[tex]\frac{b}{a}=\frac{5}{4}[/tex]
select the two values of x that are roots of this equation 2x^2 + 7x + 6=0
A. X=-3
B. X=-3/2
C. X=-4
D. X=-2
Answer:
x = -2 or x = -3/2 thus B. & D. are the answer
Step-by-step explanation:
Solve for x:
2 x^2 + 7 x + 6 = 0
Hint: | Factor the left hand side.
The left hand side factors into a product with two terms:
(x + 2) (2 x + 3) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x + 2 = 0 or 2 x + 3 = 0
Hint: | Look at the first equation: Solve for x.
Subtract 2 from both sides:
x = -2 or 2 x + 3 = 0
Hint: | Look at the second equation: Isolate terms with x to the left hand side.
Subtract 3 from both sides:
x = -2 or 2 x = -3
Hint: | Solve for x.
Divide both sides by 2:
Answer: x = -2 or x = -3/2
Answer:
B and D
Step-by-step explanation:
Given
2x² + 7x + 6 = 0
To factorise the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 6 = 12 and sum = + 7
The factors are + 4 and + 3
Use these factors to split the x- term
2x² + 4x + 3x + 6 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) + 3(x + 2) = 0 ← factor out (x + 2) from each term
(x + 2)(2x + 3) = 0
Equate each factor to zero and solve for x
x + 2 = 0 → x = - 2 → D
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex] → B

the first quartile of a data set is 72, and the third quartile is 92. Which of these values in the data set is an outlier ?
A. 61
B. 121
C. 101
D. 41
Answer: Option D
D. 41
Step-by-step explanation:
A value [tex]x_i[/tex] is considered an outlier if
[tex]x_i> Q_3 + 1.5IQR[/tex]
or
[tex]x_i <Q_1 - 1.5IQR[/tex]
Where
[tex]Q_3[/tex] is the third quartile
[tex]Q_1[/tex] is the first quartile
IQR is the interquartile range.
[tex]IQR = Q_3-Q_1[/tex]
In this case:
[tex]Q_3=92\\Q_1=72[/tex]
So
[tex]IQR = 92-72 =20[/tex]
[tex]Q_3 + 1.5IQR = 92 + 1.5*20 = 122[/tex]
[tex]Q_1 - 1.5IQR=72-1.5*20=42[/tex]
Then the outlier values will be all those greater than 122 or less than 42

d = √(x2 - x1)^2 + (y2 - y1)^2
The number next to the number does NOT mean multiply it mean like this
(x2, y2) and (x1, y1) so you would plug them in like this:
d = √(-6 - 2)^2 + (4 - (-3))^2
d = √(-8)^2 + (7)^2
d = √(64 + 49
d = √113
or 10.6301458127
Answer with Step-by-step explanation:
The distance(d) between the points (a,b) and (c,d) is given by:
[tex]d=\sqrt{(c-a)^2+(d-b)^2}[/tex]
Here, we have to find distance between (2,-3) and (-6,4)
(a,b)=(2,-3) and (c,d)=(-6,4)
[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]
[tex]d=\sqrt{8^2+7^2}[/tex]
[tex]d=\sqrt{64+49}[/tex]
[tex]d=\sqrt{113}[/tex]
Hence, the distance between the points (2 -3) and (-6 4) on the coordinate plane is:
