Answer:
Cauchy problem
Step-by-step explanation:
If you are talking about 'initial value problem', it is when talking about differential equations, an initial value problem is called a Cauchy problem by some authors as well. This is an ordinary differential equation together with a specified value which is called the initial condition. I really hope this helps!
The initial value is also known as the y intercept
What is the initial valueThe initial value, also known as the y-intercept or constant term, is a fundamental concept in mathematics, particularly in linear equations or functions. It represents the starting point or baseline on a graph, indicating the value of x is zero.
The y-intercept is where a line intersects the y-axis and serves as a reference for the function's behavior, influencing its direction and movement on the coordinate plane.
Hence we can say that The initial value is also known as the y intercept

D.acob added 3 to both sises and multiplied both sides by 2.
Answer:
A. Jacob added -3 to both sides and multiplied both sides by 1/2.Step-by-step explanation:
To solve the equation, Jacob must add -3 to both sides, and multiply by 1/2 both of them, as it's shown below:
[tex]2x+3-3=5-3\\2x=2\\\frac{2x}{2}=\frac{2}{2}\\x=1[/tex]

The density of apple juice is 1.04 grams per cm3. The density of fruit syrup is 1.6 grams per cms The density of sparkling water is 0.99 grams per cm3. 35 cm of apple juice are mixed with 25 cm3 of fruit syrup and 270 cm3 of sparkling water to make a drink with a volume of 330 cm3. Work out the density of the drink. Give your answer correct to 3 decimal places.
Answer:
Density = 1.042 grams /cm^3
Step-by-step explanation:
Work out the mass of each of three in a unit volume (cm^3)
Givens
Apple Juice = 1.04 grams / cm^3Fruit Syrup = 1.6 grams / cm^3Sparkling water = 0.99 grams / cm^3Mixture
35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams
25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 = 40 grams
270 cm^3 water = 0.99 * 270 267.3 grams
Total Mixture
Volume = 25 + 35 + 270 = 330 cm^3Mass = 36.4 + 40 + 267.3 = 343.7 gramsDensity
Density = mass / volume = 343.7 / 330 = 1.0415
Answer
1.042 grams / cm^3
The density of the resulting drink is; 1.042 grams per cm³.
To find the density of the resulting drink, we need to first determine the mass of each of the constituents.
The masses of the constituents can be found as follows;
Mass = density × volumeFor apple juice;
Mass(a) = 1.04 × 35 = 36.4gramsFor fruit syrup;
Mass(f) = 1.6 × 25 = 40grams.For sparkling water;
Mass(s) = 0.99 × 270 = 267.3gramsTherefore, the total mass of the drink is;
= 36.4 + 40 + 267.3 = 343.7 grams.And, since the total volume of the drink is 330cm³
Density of the drink = 343.7 grams/ 330 cm³Density of the drink = 1.042 grams per cm³.

Compare the graph of g(x) =x^2 +6 with the graph of f(x)=x^2
Answer:
Step-by-step explanation:
If you know what g(x) looks like, you can find f(x). Every y point of g(x) is f(x) + 6.
The general point of g(x) is (x,f(x) + 6). That is the major difference. Just so you can see it visually, the both graphs are shown below.
red: f(x) = x^2
blue: f(x) = f(x) + 6 = x^2 + 6
green: x = 2 With the two points shown that intercept the two given functions.
Purple(?): x = - 2 with the two points shown that intercept the two given functions.
The graphs of both g(x) =x² +6 and f(x)=x² are parabolas. However, while the vertex of the graph of f(x) = x^2 is at the origin, the graph of g(x) = x² + 6 is shifted upwards by six units, with the vertex of g(x) at (0,6). The shape of the two graphs is identical.
Explanation:The graphs of g(x) =x² +6 and f(x)=x² are both parabolas, but their positions differ on the coordinate plane. The function f(x) = x² is a standard quadratic function with a vertex at the origin (0,0). On the other hand, g(x) = x² + 6 is a vertical translation of the graph of f(x) = x2 upwards by six units. So, the vertex of g(x) is at the position (0, 6). Furthermore, the shape of the two graphs will remain the same as they both have the same degree and leading coefficient.

how many meters are in 5 millimeters are in 2 kilometers?
Answer:
5 mililmiters = 0,005 meters = 0,000005 kilometers
2 kilometers = 2000 meters
Step-by-step explanation:
km / hectometer / decameter / meter / dcm / centimeter / milimeter
1000 m / 100 m / 10 m < 1 > 0,1 m/ 0,01 m / 0,0001 m
1 meter = 0, 1 decimeters / 0, 01 centimeters /0, 000 1 millimeters
1 meter = 10 decameters / 100 hectometers / 1000 kilometers
so 5 millimeters = 0,005 meters = 0, 000 005 kilometers
so 2 km = 2 000 meters = 2 000 000 millimeters
the reference unit of measure is the meter.
Write all factored equivalent expressions for 12z+36
The factored equivalent expression for 12z+36 is 12(z + 3) after factoring out the common factor of 12.
Explanation:When asked to write all factored equivalent expressions for 12z+36, we look for common factors. Both terms have a common factor of 12. Factoring out the 12, we get 12(z + 3). There are no other common factors, and the expression cannot be factored further as both terms within the parentheses are prime with respect to each other.
what is the 20th term of the arithmetic sequence 8,21,34,47,60,..
Well considering that

F (x) = f(x-1) + 13
(Meaning the previous term plus 13)
So
F (x) = 13x - 5
F (0) = -5
The 20th term of the given arithmetic sequence 8, 21, 34, 47, 60... is 255.
Explanation:In the field of mathematics, this type of problem is referred to as an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. This difference is called the common difference.
In your question, the arithmetic sequence provided is 8, 21, 34, 47, 60... Here, the common difference is 13 (i.e., every term after the first is 13 more than the preceding term).
To find any term (let's say the nth term) in an arithmetic sequence, you can use the formula:
nth term = first term + (n - 1) * common difference
Applying this formula to find the 20th term:
20th term = 8 + (20 - 1) * 13 = 8 + 247 = 255

{y=2x-4; x+2y=12}
Substitute y = 2x - 4 to x + 2y = 12:
x + 2(2x - 4) = 12 use distributive property
x + (2)(2x) + (2)(-4) = 12
x + 4x - 8 = 12 add 8 to both sides
5x = 20 divide both sides by 5
x = 4
Put the value of x to the first equation:
y = 2(4) - 4
y = 8 - 4
y = 4
Answer: x = 4 and y = 4Answer:
x=4, y=4
Step-by-step explanation:
y=2x-4;
x+2y=12
We can use substitution since the first equation is solved for y
Where ever you see y in the second equation, replace it with 2x-4
x + 2(2x-4) = 12
Distribute the 2
x+4x-8 = 12
Combine like terms
5x-8=12
Add 8 to each side
5x-8+8=12+8
5x=20
Divide by 5
5x/5 = 20/5
x =4
We still need to solve for y
y = 2x-4
We know x =4
y = 2(4) -4
y = 8-4
y=4

Answer:
y = 6/5 x-1 slope intercept form
6x-5y = 5 standard form
Step-by-step explanation:
We have the points (0,-1) and (-5,-7)
We can find the slope using
m = (y2-y1)/(x2-x1)
= (-7--1)/(-5-0)
= (-7+1)/(-5-0)
= -6/-5
= 6/5
We also have the y intercept ( when x=0) It is -1
We can use the slope intercept form of the equation y = mx+b
y = 6/5 x-1
Depending on what you mean when you say simplify your answer
We can put it in standard form ax+by = C
Multiply both sides by 5
5y =5* 6/5 x-1*5
5y = 6x-5
Subtract 6x from each side
-6x+5y = 6x-6x-5
-6x+5y = -5
Multiply by -1
6x-5y = 5

x = -2The height of the water in an a over ground pool is 3ft. As the number of water drains ,the rate of -1/2 inch per minute. Write and solve an equation to find how many minutes it will take to drain the pool
Answer:
36 - 1/2x = 0
72 minutes
Step-by-step explanation:
there is a total of 3 feet in the pool at the start, 1 ft = 12 in, and 3 ft = 36 in. the pool is losing water, so we have to subtract. it is losing water at a rate of -1/2 in per minute, and we don't know how many minutes it will take
we have to set it equal to 0 because we are trying to find out how long it will be until the pool is completely drained, which is when there will be no water left, so it will be 0
subtract 36 from both sides
-1/2x = -36
divide both sides by -1/2
x = 72

The desired form is a rearrangement of the given equation, divided by the leading coefficient.
Monic polynomialA monic polynomial is one with a leading coefficient of 1. The desired form requires that we start from that condition. In order to avoid fractions, we can begin by subtracting the constant term on the left.

Step-by-step explanation:
See , we know area of a trapezoid is equal to 1/2*(sum of parallel sides)* perpendicular distance between parallel sides.
Here B and b are parallel sides which we know by comparing the equation.
And 'h' here is the perpendicular distance between parallel sides.
We have to write the equation in terms of one of the parallel sides 'b'
Our formula is A = 1/2*h*(B+b)
I.e. 2A = h*(B+b) (Multiplying both sides by 2)
