Use the divisibility rules to determine which of the following numbers 504 is divisible by. (Check all that apply.)
2
3
5
7
11
Answers
The number 504 is divisible by 2, 3, and 7 using the divisibility rules. It is not divisible by 5 as it does not end in 0 or 5, and not by 11 as the difference between the sum of alternating digits is not a multiple of 11.
To determine which numbers 504 is divisible by using the divisibility rules, we can examine each option provided:
2: A number is divisible by 2 if it is even, that is, if its last digit is 0, 2, 4, 6, or 8. Since 504 ends with a 4, it is divisible by 2.
3: A number is divisible by 3 if the sum of its digits is a multiple of 3. For 504, the sum of its digits is 5 + 0 + 4 = 9, which is a multiple of 3, so 504 is divisible by 3.
5: A number is divisible by 5 if its last digit is 0 or 5. Since 504 ends with a 4, it is not divisible by 5.
7: To determine divisibility by 7, there isn't a simple rule like there is for 2 or 5. However, through manual calculation or knowledge, we can confirm 504 is 7 times 72, and therefore, it is divisible by 7.
11: A number is divisible by 11 if the difference between the sum of the digits in the odd positions and the sum of the digits in the even positions is a multiple of 11 or 0. For 504, (5 - 0 + 4) = 9 which is not a multiple of 11, so 504 is not divisible by 11.
In conclusion, 504 is divisible by 2, 3, and 7.
Which of these is an odd function?
Question 11 options:
f(x) =3x2+7
f(x) =2x3+x
f(x) =5x2−6
f(x) =4x3+2x2
Answers
Answer:
[tex]f(x)=2x^3+x[/tex]
Step-by-step explanation:
An odd function f is one where [tex]f(-x)=-f(x)[/tex]. We can interpret this is meaning: reflecting the graph horizontally [tex]f(-x)[/tex] has the same effect as reflecting it vertically [tex]-f(x)[/tex] . The only graphs that meet this requirement are ones with reflectional symmetry across the line y = x, so we can immediately elimate the functions [tex]f(x)=3x^2+7[/tex] and [tex]f(x)=5x^2-6[/tex], which have horizontal symmetry, but not the kind of symmetry we're looking for.
That leaves us with [tex]f(x)=2x^3+x[/tex] and [tex]f(x)=4x^3+2x^2[/tex]. One feature of exponents we can utilize is that -1 to an even power is 1, while -1 to an odd power is -1. If we want [tex]f(-x)=-f(x)[/tex], we need to flip the signs of all the coefficients, and we can only do that if all the powers of x are odd. The only function with only odd powers of x is [tex]f(x)=2x^3+x[/tex], and plugging in -x to the function reveals that
[tex]f(-x)=2(-x)^3+(-x)\\f(-x)=-2x^3-x=-(2x^3+x)=-f(x)[/tex]
So [tex]f(x)=2x^3+x[/tex] the only odd function on the list!
Cesar had a part-time job last year. He worked every week for the year and made $23 an hour. He worked 28 hours each week. Cesar saved what was left of his earnings after paying all of his monthly expenses. At the end of the year, he had saved $3,360. What were Cesar’s average monthly expenses, rounded to the nearest dollar?
A. $1,288
B. $1,680
C. $2,403
D. $2,511
E. $2,791
Answers
Answer:
D. $2,511
Step-by-step explanation:
First off, we need to write down the facts we know.
There are about 52.177 weeks in a year
Cesar works 28 hours each week
Cesar makes $23 an hour
There are 12 months in a year
Cesar has $3,360 after his monthly expenses
To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply Cesar's 28 hour work week by about 52.177 weeks. That makes 1,456 hours in his work year. That means he makes $33,492 a year. If you multiply $2,511 by the months in a year (12), you get $30132. Finally, subtract his annual salary by $30132 to get $3,360, which is what was left of Cesar's earnings after paying all of his monthly expenses.
Cesar's average monthly expenses, rounded to the nearest dollar, were $2,511.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Cesar worked every week for the year, which is 52 weeks.
Therefore,
He worked a total of 52 x 28 = 1,456 hours.
If he made $23 an hour, then his total earnings for the year would be
1,456 x $23 = $33,488.
If he saved $3,360 after paying all of his monthly expenses, then his total expenses for the year would be:
$33,488 - $3,360 = $30,128
To find his average monthly expenses, we can divide his total expenses for the year by 12:
= $30,128 ÷ 12
= $2,510.67
Rounding this to the nearest dollar, we get an answer of $2,511
Therefore,
Cesar's average monthly expenses, rounded to the nearest dollar, were $2,511.

24. One card from a deck of cards is
selected, it is replaced, and another card is
chosen. What is the probability that the first
card is a black card and the second is a red
card?
Answers
Answer:
0.25
Step-by-step explanation:
1/2 the cards are red and 1/2 are black so it is 0.5 x 0.5
The probability that the first card drawn is a black card and the second is a red card, with replacement, is 1/4 or 25%.
In probability, when we talk about selecting cards with replacements from a deck, the chances of any single card being drawn remain constant regardless of previous draws. A standard deck of cards has 26 black cards and 26 red cards. The probability of drawing a black card is P(Black) = 26/52, and similarly, the probability of drawing a red card is P(Red) = 26/52. When we draw one card, replace it, and then draw again, the outcomes are independent since the replacement restores the deck to its initial state.
The probability of the first card being black and the second card being red is the product of the individual probabilities of each event:
P(Black then Red) = P(Black) times P(Red)P(Black then Red) = (26/52) times (26/52) = 1/2 times 1/2P(Black then Red) = 1/4Therefore, the probability that the first card drawn is black and the second is a red card is 1/4 or 25%.

Evaluate the expression x3+x2 for x=4
Answers
Final answer:
To evaluate the expression x^3 + x^2 for x=4, you substitute 4 into the equation, resulting in 4^3 + 4^2, which is 64 + 16, equalling 80.
Explanation:
The question asks to evaluate the expression x^3 + x^2 for x=4. To do this, we simply substitute 4 into the expression.
First, calculate 4 to the power of 3 (4^3), which is 64. Next, calculate 4 to the power of 2 (4^2), which is 16. Finally, add these two results together: 64 + 16 = 80.
Therefore, x^3 + x^2 evaluated for x=4 is 80.
To evaluate the expression x^3 + x^2 for x=4, substitute the value of x into the expression, resulting in 4^3 + 4^2, which simplifies to 64 + 16, and the final answer is 80.
Explanation:To evaluate the expression x^3 + x^2 for x=4, we need to substitute the value of x into the expression and simplify it. Firstly, we calculate x to the power of 3, which is 4^3, and x to the power of 2, which is 4^2.
4^3 = 4 × 4 × 4 = 64
4^2 = 4 × 4 = 16
Now, we add the results together:
64 (which is 4^3) + 16 (which is 4^2) = 80
Therefore, when we evaluate the expression for x=4, the result is 80.

One side of a rectangle is 2 m shorter than another side. The area is 360 m2. Write a quadratic equation and solve it to find the length of the longer side of the rectangle
Answers
Answer:
Step-by-step explanation:
Let one of the side = x
So, other side = x - 2
Area = 360 sq.m
x*(x - 2) = 360
x*x - x * 2 = 360
x² - 2x -360 = 0
x² + 18x - 20x - 18*20 = 0
x(x +18) - 20*(x + 18 ) = 0
(x + 18)(x -20) = 0
{x + 18 is ignored as measurement will not be a negative number}
x - 20 = 0
x = 20
Length of the longer side = 20 m

How many x-intercepts does the graph of this
quadratic have?
Two x-intercepts
One x-intercept
No x Intercepts
Answers
Answer:
A.)
Two x-intercepts
Step-by-step explanation:
This question pertains to determining the number of x-intercepts a given quadratic equation has. To solve this, the discriminant of the quadratic equation would need to be calculated, which subsequently determines the number of x-intercepts (if repeated D>0 equals two, D=0 equals one and D<0 means none). The exact number for this specific equation could not be calculated due to an unclear part in the question.
Explanation:The equation y = 0.5x^2 -6x + 3 is an equation of a quadratic function. The x-intercepts of this function can be found by setting y to 0 and solving the equation for x. A quadratic equation, however, can have two, one, or no x-intercepts, depending on its discriminant (D). The discriminant is found with the equation D = b^2 - 4ac from the general form of a quadratic equation which is ax^2+bx+c = 0. If D > 0 the quadratic has two x intercepts, if D = 0 then it has exactly one and if D < 0 it has none.
For our equation (0,5x^2-6x+3), the discriminant (D) could be calculated as: D = (6)^2 - 4*(0,5)*3. After this calculation, we could determine the number of x-intercepts but since this is not fully clarified in the question, we can't provide a definite answer.

Answers
Answer:
4x +6
Step-by-step explanation:
(x+4) + (3x+2)
Combine like terms
x+3x +4+2
4x +6
To find the sum of the expressions (x+4) and (3x+2), one combines like terms. The sum of the x terms, 1x and 3x, is 4x and the sum of the constants, 4 and 2, is 6. Hence, the sum of the given expressions is 4x + 6.
Explanation:To find the sum of two expressions, (x+4) and (3x+2), we need to follow a process known as combining like terms. In arithmetic and algebra, 'like terms' are terms that have the same variables and powers. In this case, the 'like terms' are x in (x+4) and 3x in (3x+2).
Adding these two expressions, we get:
(x + 4) + (3x + 2)
To combine like terms, we add the coefficients of the x terms together (1x and 3x) and we add the constants together (4 and 2).
Sum of x terms: x + 3x = 4x
Sum of constants: 4 + 2 = 6
So, the sum of (x + 4) and (3x + 2) is 4x + 6.
