5,10,15,20,25 is this an arithmetic or geometric sequence
Because of the common difference of 5, this series is math because it has a common difference of 5.
What in mathematics is an arithmetic sequence?An arithmetic series is one in which each term grows by adding or removing a certain number, k. In a geometric series, each term grows by dividing by or increasing by a certain constant k. For instance, a1 = 25 and a(n) Equals a(n-1) Plus 5.
This is a list of numbers.
Each term in an arithmetic series is created by adding a fixed difference to the term before it. The distance between successive words in this order is 5:
10 - 5 = 5
15 - 10 = 5
20 - 15 = 5
25 - 20 = 5
Therefore, this sequence has a common difference of 5, which means it is an arithmetic sequence.

number that multiply to 375 but adds to -10
The two numbers that multiply to 375 and add to -10 are -25 and 15.
How to find two numbers that multiply ?To find two numbers that multiply to 375 but add to -10, we can use a system of equations.
Let's call the two numbers we're looking for x and y. Then we have:
xy = 375 (since they multiply to 375)
x + y = -10 (since they add to -10)
We can use the second equation to solve for one variable in terms of the other. For example, if we solve for y, we get:
y = -x - 10
Now we can substitute this expression for y into the first equation:
x(-x - 10) = 375
Expanding the left side gives:
-x^2 - 10x = 375
Bringing everything to one side gives:
x^2 + 10x - 375 = 0
We can factor this quadratic equation as:
(x + 25)(x - 15) = 0
This gives us two possible values for x: x = -25 or x = 15.
If x = -25, then y = -10 - (-25) = 15.
If x = 15, then y = -10 - 15 = -25.
So, The two numbers that multiply to 375 and add to -10 are -25 and 15.

Andrea is buying some new shirts and sweaters. She is able to buy 3 shirts and 2 sweaters for $120, or she is able to buy 2 shirts and 4 sweaters for $160. How many dollars does a shirt cost? How many dollars does a sweater cost?
Answer:
Shirt = $20
Sweater = 30
Step-by-step explanation:
3sh + 2sw = 120
2sh + 4sw = 160
Multiply (3sh + 2sw = 120) by -2
-6sh + -4sw = -240 -> -6sh -4sw = -240
Add the two equations -6sh -4sw = -240 and 2sh + 4sw = 160 together. -4sh = -80

Write the equation of a rational function that has been translated left 2 units and shifted up 1 unit.
The equation of a rational function that has been translated left 2 units and shifted up 1 unit is; f(x) = (a(x - 2) + b + 1) / (c(x - 2) + d)
What is the equation after transformation?A relation is defined as a function in the event that it possesses only One y-value with a corresponding x-value.
A general form of how a rational function is represented is:
f(x) = (ax + b) / (cx + d)
To translate this function left 2 units, we need to replace x with x + 2. This gives us:
f(x + 2) = (a(x + 2) + b) / (c(x + 2) + d)
To shift this function up 1 unit, we need to add 1 to the numerator. This gives us:
f(x + 2) = (a(x + 2) + b + 1) / (c(x + 2) + d)
Therefore, the equation of a rational function that has been translated left 2 units and shifted up 1 unit is: f(x) = (a(x - 2) + b + 1) / (c(x - 2) + d)

The final RSVP guest count is 60 people Which catering company will offer the best deal for your family? How much money will your family save by choosing that company
a) The family's best deal is with Smokey's BBG which charges $780 for 60 guests.
b) Choosing Smokey's BBG over Bennie's BBQ will save (difference) the family $40.
How is the difference or saving determined?The total cost for each company's catering services is worked out using their cost functions.
Smokey's BBG does not charge a fixed cost, unlike Bennie's BBG.
The difference between the total costs of the companies is obtained by subtraction.
The number of guests = 60
Smokey's BBQ Bennie's BBQ
Catering Fees $0 $100
Charge per person $13 $12
The total charge for 60 $780 ($13 x 60) $820 ($100 + $12 x 60)
Difference between the charges = $40 ($820 - $780)
However, using a system of equations we can determine the number of guests that makes the total cost the same for each company as 100.
Thus, comparing the total costs for the two companies shows the difference or cost savings to be gained by the family.

x = -1 (multiplicity 2)
Step-by-step explanation:
Given the cubic f(x) = x³ -x² -5x -3 has x=3 as a root, you want the other roots.
Quadratic factorYou can find the quadratic factor of the polynomial using synthetic division. That tells you ...
f(x) = (x -3)(x² +2x +1)
You recognize the quadratic factor as the perfect square trinomial ...
x² +2x +1 = (x +1)²
RootsThe remaining roots will be the values of x that make these factors zero:
x +1 = 0 ⇒ x = -1 . . . . . and the other is the same: multiplicity 2
The remaining roots are x=-1 and x=-1.

A coordinate plane with a line passing through (negative 5, 4) and (0, 3). A coordinate plane with a line passing through (negative 4, negative 6) and (0, 3). A coordinate plane with a line passing through (negative 1, negative 4), (0, 0) and (1, 4). Mark this and return
The variable y is directly proportional to x, which is the definition of direct variation.
What is coordinate geometry?The intersection of two perpendicular lines, the x-axis and the y-axis, results in a 2D plane known as a coordinate plane. In geometry, a coordinate system is a method for calculating the positions of the points using one or more integers or coordinates.
The graph that represents a function with direct variation is a coordinate plane with a line passing through (0, 0) and some other point that is not the origin.
Out of the given options, the graph that represents a function with direct variation is the coordinate plane with a line passing through (negative 4, 0) and (0, negative 2).
This is because the equation of this line can be written in the form y = mx, where m is the slope of the line. In this case, the slope is:
m = (0 - (-2)) / (-4 - 0) = 1/2
So the equation of the line is y = (1/2)x - 2, which is in the form of y = kx, where k = 1/2. This means that y is directly proportional to x, which is the definition of direct variation.

The concentration οf hydrοgen ions in a sοlution with pH 2.44 is [tex]2.754\times 10-12 M[/tex]
What is the pH value?
The pH value is a measure οf the acidity or basicity of a solution. It is defined as the negative lοgarithm (base 10) of the concentration of hydrogen ions (H+) in moles per liter (mol/L) of solutiοn. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral. Solutions with a pH less than 7 are acidic, while solutiοns with a pH greater than 7 are basic οr alkaline.
a) Given pH = 2.44
We knοw pH + pOH = 14,
pOH = 14 - 2.44 = 11.56
[tex][H+] = 10^{-pH} = 10^{-2.44} = 3.63\times 10 ^{-3} M[/tex]
[tex][OH-] = 10-pOH = 10-11.56 = 2.754\times 10-12 M[/tex]
b) Given ,pOH = 10.85
and it is knοwn that pH + pOH = 14, thus pH = 14 - 10.85= 3.15
[tex][H+] = 10^{-pH} = 10^{-3.15} = 7.07\times10^{-4 M}[/tex]
[tex][OH-] = 10^{-pOH} = 10^{-10.85} = 1.41\times10^{-11} M[/tex]
c) Given pH = -0.65
and it is knοwn that pH + pOH = 14, thus pOH = 14 +0.65 = 14.65
[tex][H+] = 10^{-pH} = 10^{0.65} = 4.466 M[/tex]

we will need at least 96 bags of sand to cover the base of the circular pool.
what is circle?
A circle is a two-dimensional geometric shape consisting of all the points that are equidistant from a given point, called the center.
The area of a circular pool with a diameter of 22 feet can be calculated using the formula:
A = πr^2
where A is the area of the circle, π is a constant (approximately equal to 3.14), and r is the radius of the circle (which is half the diameter).
In this case, the diameter is 22 feet, so the radius is:
r = d/2 = 22/2 = 11 feet
Now we can calculate the area of the circle:
A = πr^2 = 3.14 x 11^2 = 379.94 square feet (rounded to 2 decimal places)
To cover this area with sand, we need to know how many bags of sand are required. We are told that one bag of sand covers about 4 square feet, so we can calculate the number of bags of sand required as follows:
Number of bags = Area of pool / Area covered by one bag
Number of bags = 379.94 square feet / 4 square feet per bag
Number of bags ≈ 95 bags
Since we need to round up to a whole number of bags, we will need at least 96 bags of sand to cover the base of the circular pool.

Answer: The correct answer is yes, he brought enough money to get into the park.
Step-by-step explanation:
Well, let's analyze the information provided:
Admission to the amusement park for 8 students is $ 100. If each student agreed to share of cost equally, it means that we must divide those 100, for each of those students.
Therefore it will remain 100/8 = 12.5
If each student must pay 12.5, and Noah brought $ 13, that means he will have enough money to enter the park, and he will even have $ 0.50 left over.
