Mariam wants to rent out her house. She researches similar listings in an online rental marketplace and sees that she can rent her home for $210$ per night or $1300 per month. Mariam's house is near a beach in a moderate-sized city with good weather year-round, a famous aquarium, a water park, and lots of restaurants.
To figure out if she should list her home as a short-term rental or a long-term rental, first Mariam divides 1300 by 210.
1300/210=6.2
She needs to rent her home 6-7 nights per month to match the revenue from a long-term rental. Since Mariam lives in a location likely to have tourists, she should find plenty of renters. She lists her home as a short-term rental.
In her reasoning, Mariam divided 1300 by 210. If this is correct, explain why. If this is not correct, explain what she should have done.
This is absolutely correct as dividing the rate per month by the rate per night gives the number of nights per month needed for the revenues to match: [tex]$$month$\div $night=r/month \cdot \ $night/r$=# $nights/month$$[/tex]

Answer:
b = 259
Step-by-step explanation:
You want the smallest positive 'b' that makes x² +bx +2008 have integer solutions.
FactorsWhen the polynomial is factored, you have ...
(x +p)(x +q) = x² +(p+q)x +pq
Comparing this to the given expression, we see that ...
p + q = b

B = 11%
Let investment A = a and investment B = b
Equations:0.07a + 0.11b = 460 ... Equation 1
a + b = 6,000 ... Equation 2
Multiply Equation 2 by 0.07:
Equation 3: 0.07a + 0.07b = 420
Subtract Equation 3 from Equation 1:
0.07a + 0.11b = 460

The value of g becomes 64% of its value on the surface of the earth when it is at a height of 3200km above the surface, with the radius of the earth being 6400km.
Radius of Earth = 6400 km
Height above the surface of Earth = 3200 km
Gravitational Acceleration on surface of Earth = 9.8 m/s2
Gravitational Acceleration at 3200 km above the surface of Earth = 9.8 x 0.64 = 6.272 m/s2
The gravitational acceleration (g) on the surface of the earth is 9.8 m/s2. This value is constant, regardless of the height of an object above the surface. However, as the height of an object increases, the gravitational force experienced by the object decreases. The radius of the earth is 6400 km, so at a height of 3200 km above the surface, the gravitational acceleration experienced by an object is 64% of its value on the surface of the earth, which is 6.272 m/s2.

[tex]1.\; -8x^3y^5\\\\2\; \dfrac{2y^3}{3}\\\\3.\; They are both equal\\\\4.\; 3x^2\\\\[/tex]
Step-by-step explanation:
First let's understand what an exponent is.
When a number or a term or an expression is multiplied repeatedly by itself, an exponent can be used to represent this situation
for example,
5 x 5 x 5 x 5 x 5 x 5 = 5⁶ since 5 is multiplied by itself 6 times
Here the number being multiplied(5) is called the base and the number of times it is multiplied(6) is called the exponent.
There are some rules regarding exponentiation
1 Zero Exponent
Any number raised to the power zero is 1
[tex]4^0 = 1\\\\123.456^0 = 1\\\\x^0 = 1[/tex]
2. Negative Exponent
If the exponent if negative, the expression is equivalent to the reciprocal of the term raised to the positive exponent
In general
[tex]a^{-m} = \dfrac{1}{a^m}\\\\and\\\\\dfrac{1}{a^{-m}} = a^m\\\\[/tex]
Examples:
[tex]x^-1 = \dfrac{1}{x}\\\\\left({x + y}\right)^{-a} = \dfrac{1}{(x+y)^a}[/tex]
[tex]\dfrac{1}{x^{-3}} = x^3[/tex]
3. Product Rule
When you multiply exponents with the same base the exponents get added
In general
[tex]\displaystyle {a^m a^n = a^{m + n}}[/tex]
Examples
[tex]x^3x^6 = x^{(3+6)} = x^9\\\\[/tex]
4. Quotient Rule
When you divide an exponentiated term by another exponentiated term with the same base the resulting exponent is the difference between the two exponents:
In general
[tex]\dfrac{a^m}{a^n} = a^{m-n[/tex]
Examples
[tex]\dfrac{y^3}{y^2} = y^{3-2} = y^1 = y[/tex]
5. Power Rule 1
An exponent term raised to another power will be the base raised to the product of the two exponents
In general
[tex](a^m)^n = a^{mn}[/tex]
[tex](x^3)^4 = x^{3 \cdot 4} = x^{12}[/tex]
6. Power Rule 2
If the base is the product of two or more terms and the whole expression is raised to a power then each individual term gets raised to that power.
[tex](ab)^m = a^mb^m\\\\(2x^3y^2z^4)^4 = 2^4x^{3.4}y^{2.4}z^{4.4} = 16x^{12}y^8z^{16}[/tex]
7. One exponent
Any term raised to the power 1 is itself
[tex]a^1 = a[/tex]

x¹ = x

Given: GH is parallel to KL; GJ is congruent to KJProve: J is the midpoint of HLThe shape is an hour glass figure. GH on the left side J in the middle and LK on the right side.
The distance between J and L is (Gx/2)2 + (Gy/2)2. This proves that J is the midpoint of HL.
Given: GH is parallel to KL and GJ is congruent to K
To prove: J is the midpoint of HL
We can use the Midpoint Formula to prove that J is the midpoint of HL. The midpoint formula states that the midpoint of a line segment is the average of the x-coordinates and the average of the y-coordinates. In this case, the x-coordinate of J is (Gx + Kx) ÷ 2 and the y-coordinate of J is (Gy + Ky) ÷ 2. Since GH and KL are parallel, Gx = Kx and Gy = Ky. Therefore, the x-coordinate of J is (Gx + Kx) ÷ 2 = Gx ÷ 2 and the y-coordinate of J is (Gy + Ky) ÷ 2 = Gy ÷ 2. Since GJ is congruent to KJ, Gx = Kx and Gy = Ky. Therefore, J is the midpoint of HL.
We can also use Distance Formula to prove that J is the midpoint of HL. The distance formula states that the distance between two points is the square root of the difference of the x-coordinates squared plus the difference of the y-coordinates squared. In this case, the distance between G and J is the square root of (Gx - Jx)2 + (Gy - Jy)2. Since GJ is congruent to KJ, Gx = Kx and Gy = Ky. Therefore, the distance between G and J is the square root of (Gx - Jx)2 + (Gy - Jy)2 = (Gx - Gx/2)2 + (Gy - Gy/2)2 which simplifies to (Gx/2)2 + (Gy/2)2. This is the same distance as the distance between J and L, since GJ is congruent to KJ, Gx = Kx and Gy = Ky. Therefore, the distance between J and L is (Gx/2)2 + (Gy/2)2. This proves that J is the midpoint of HL.

Which of the following are options you can select in the Top Values list for a query? Select all the options that apply.a. all b. 25% c. 5 d. none
All, 25%, and 5 are all valid options that can be selected in the Top Values list for a query.
All will display all the values in the query, 25% will display the top 25% of the values, and 5 will display the top 5 values.
To calculate 25%, we can use the formula (value/total)*100. For example, if the total number of values is 20, then 25% would be (20/20)*100 = 100. This would display all 20 values in the query. Similarly, if the total number of values is 50, then 25% would be (50/50)*100 = 100, which would also display all 50 values.
To calculate 5, we can use the same formula (value/total)*100. For example, if the total number of values is 20, then 5 would be (5/20)*100 = 25. This would display the top 5 values in the query. Similarly, if the total number of values is 50, then 5 would be (5/50)*100 = 10, which would also display the top 5 values.

Relationships between short- and long-term exposure to violent video games and desensitization, as measured through components of moral evaluation, were examined. Sixty-six children aged 5-12 years old completed questionnaires assessing video game experience and preferences and empathy and attitudes toward violence. The children played a violent or nonviolent video game and then responded to vignettes about everyday occurrences. Vignette responses were coded for aggression and empathy. Preexisting empathy and attitudes towards violence were positively related to the corresponding vignette scores. Long-term exposure to violent video games contributed to lower empathy vignette scores. Playing a violent versus a nonviolent game did not affect vignette responses. Results suggest that long-term exposure to violent video games may be associated with desensitization as reflected in lower empathy, although the direction of causality remains unclear.What is the main IV?What is the main DV?
