Using the calculus rule, we can rewrite the total derivative (dx/dz) at constant y as the sum of two partial derivatives.
The total derivative (dx/dz) at constant y can be rewritten as the sum of two partial derivatives:
(dx/dz) = (∂x/∂y)*(∂y/∂z) + (∂x/∂z) at constant y
Apply the chain rule
The chain rule in calculus allows us to find the derivative of a function with respect to another variable, by considering how the intermediate variables change.
In this case, we want to find (dx/dz) at constant y.
The chain rule states:
(dx/dz) = (dx/dy)*(dy/dz) + (dx/dz) at constant y
Identify the partial derivatives:
Since we want to rewrite (dx/dz) as a sum of two partial derivatives, we will keep the terms (dx/dy) and (dy/dz) as partial derivatives:
(dx/dz) = (∂x/∂y)*(∂y/∂z) + (∂x/∂z) at constant y
Final answer
The total derivative (dx/dz) at constant y can be rewritten as the sum of two partial derivatives:
(dx/dz) = (∂x/∂y)*(∂y/∂z) + (∂x/∂z) at constant y.

A company is designing a new cylindrical water bottle. The volume of the bottle will be 220 cm cubed 3. The height of the water bottle is 8. 9 cm. What is the radius of the water bottle? Use 3. 14 for π
The radius of the cylindrical water bottle is approximately 2.34 cm.
The company designing the water bottle has given us the volume of the bottle, which is 220 cm³, and the height of the bottle, which is 8.9 cm. We can use the formula for the volume of a cylinder to relate the radius, height, and volume of the water bottle. The formula is:
Volume of a cylinder = π × radius² × height
We are given the volume of the cylinder as 220 cm³ and the height as 8.9 cm, so we can substitute these values into the formula to get:
220 = π × radius² × 8.9
To solve for the radius, we need to isolate it on one side of the equation. We can start by dividing both sides by π × 8.9:
220 ÷ (π × 8.9) = radius²
Now, we can take the square root of both sides to find the value of the radius:
√(220 ÷ (π × 8.9)) = radius
Using 3.14 for π, we can simplify the expression to get:
radius ≈ 2.34 cm

What are the steps to finding out 4. 25 - 7. 06?
The result of subtracting 7.06 from 4.25 is -2.81.
Let's see how these steps apply to the problem at hand:
4.25
-7.06
In this case, we don't need to borrow because the top number 4.25 is already smaller than the bottom number 7.06.
Starting from the rightmost column, we subtract 5 from 6. Since 6 is larger than 5, we can subtract 5 from 6 and get 1. We write down 1 in the hundredths column.
Next, we move to the tenths column and subtract 2 from 0. We can't do this, so we need to borrow 1 from the digit in the ones column. The 4 in the ones column becomes 3, and the 2 in the tenths column becomes 12.
Now we can subtract 2 from 12, which gives us 10. We write down 0 in the tenths column and carry 1 to the ones column.
In the ones column, we have 3 - 7 - 1 (the borrowed 1) = -5. Since we can't have a negative number in this position, we need to borrow again from the digit in the tens column. The 2 in the tens column becomes 12, and we bring down the borrowed 1 to the ones column.
Now we can subtract 7 from 12, which gives us 5. We write down 5 in the ones column.
Step 4: Bring down any digits that have not been used.
We don't have any digits left to bring down, so we have finished the subtraction.
Therefore, the result of subtracting 7.06 from 4.25 is -2.81.

How do you find the legs of a 45-45-90 triangle if you know the length of the hypotenuse?
Each leg of the triangle has a length of 5√(2) units
Since the triangle is 45-45-90, each of the two legs has the same length, which we'll call x. By the Pythagorean theorem, we know that:
x² + x² = h²
Simplifying this equation, we get:
2x² = h²
To solve for x, we can divide both sides by 2 and then take the square root:
x = h / √(2)
This tells us that each leg of a 45-45-90 triangle is equal to the hypotenuse divided by the square root of 2.
Let's say you have a 45-45-90 triangle with a hypotenuse of length 10. To find the length of each leg, you would use the formula:
x = h / √(2)
Substituting h = 10, we get:
x = 10 / √(2)
To simplify this expression, we can rationalize the denominator by multiplying both the numerator and denominator by √(2):
x = (10 / √(2)) * (√(2) / √(2))
= 10√(2) / 2
= 5√(2)

The diameter of a circle is 170 inches. The circle has two chords of length 26 inches. What is the distance from each chord to the center of the circle?
the distance from each chord to the center of the circle is 85 inches.
what is chord ?
In geometry, a chord is a line segment that connects two points on the circumference of a circle. It is the straight line that intersects a circle at two points. In other words, a chord is a line segment that lies entirely inside the circle and connects two points on the circle.
In the given question,
If we draw a diagram of the circle with diameter 170 inches, we can see that the chords of length 26 inches divide the circle into two regions. We are interested in finding the distance from each chord to the center of the circle.
To solve this problem, we can use the following formula:
distance from chord to center = 1/2 * √(4r² - c²)
where r is the radius of the circle and c is the length of the chord.
First, we need to find the radius of the circle. The radius is half of the diameter, so:
r = 1/2 * diameter = 1/2 * 170 = 85 inches
Next, we can use the formula above to find the distance from each chord to the center of the circle. Plugging in the values we have:
distance from chord to center = 1/2 * √(4r² - c²)
distance from chord to center = 1/2 * √(4(85)² - 26²)
distance from chord to center = 1/2 * √(28,900)
distance from chord to center = 1/2 * 170
distance from chord to center = 85
Therefore, the distance from each chord to the center of the circle is 85 inches.

Kendrick attends a private school where he must wear a uniform. Last year, the price of the uniform was $52. This year's uniform price was $65. What is the percent of increase in the cost of the uniform?
The percent increase in the cost of the uniform from last year to this year is 25%.
What is the percent of increase in the cost of the uniform?To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.
The difference between this year's price and last year's price is:
$65 - $52 = $13
The original price (last year's price) is $52.
So the percent increase in the cost of the uniform is:
percent increase = (difference / original price) x 100
percent increase = ($13 / $52) x 100
percent increase = 0.25 x 100
percent increase = 25%
Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

find the antiderivative:x/square root of x
The antiderivative of f(x) = x/√x is [tex](2/3)x^{3/2} + C[/tex],
where C is the constant of integration.
To find the antiderivative of the given function.
The function is: f(x) = x/√x
First, let's rewrite the function in a more convenient form for integration:
f(x) = x / √x
[tex]= x / x^{1/2}[/tex]
[tex]= x^{1 - 1/2}[/tex]
[tex]= x^{1/2}[/tex]
Now, let's find the antiderivative using the power rule for integration:
∫[tex]x^{1/2} dx[/tex]
To apply the power rule, we need to add 1 to the exponent and then divide by the new exponent:
Antiderivative = [tex](x^{(1/2) + 1)) / ((1/2) + 1} ) + C[/tex]
Antiderivative =[tex](x^{3/2/ 3/2} + C)[/tex]
Finally, multiply by the reciprocal to simplify the expression:
Antiderivative = [tex](2/3)x^{3/2} + C.[/tex].
An antiderivative, also known as an indefinite integral, is a function that, when differentiated, yields a given function. In other words, an antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x).
For example, if f(x) = 2x, then an antiderivative of f(x) would be F(x) = x^2 + C,
where C is a constant of integration.

Y'all I really need some help here. 100 points.
Answer:
42 degrees
Step-by-step explanation:
So, first to find <QUT, which is a vertical angle, we have to figure out either QUR or TUS. So:
9x+3=11x-27
solve for x:
x=15
Then, plug it into one of the equations. Let's use 9x+3.
9(15)+3=138
So, we know that QUR is 138 degrees.
That means that TUS is ALSO 138.
138x2=276
Now we know that QUT and RUS have to equal whatever 360-276 is:
360-276=84
QUT and RUS have to equal 84 degrees, so we DIVIDE by 2.
84/2=42
So, QUT=42 degrees
Answer:
42 Degrees
Step-by-step explanation
Becuase (11x-27) and (9x+3) are vertical angles that means they are equal to each other
(11x - 27) = (9x + 3)
First you will add 27 to both sides
11x -27 = 9x +3
+27 +27
Making it to:
11x = 9x + 30
Now you need to subtract 9x from both sides
11x = 9x +30
-9x -9x
Turning it into this
2x= 30
Now Lastly, divide both sides by 2
2x = 30
2x 2x
And the answer is...... X=15
Now that you have the x value, we go back to the 11x-27 and replace the X with 15
11(15) -27 = 138 degress
Now because angle QUT and 138 degrees make a straight line that means together they will be 180 degress so you will subtract 180 by 138
Giving you the final answer of
42 Degrees
