The differential equations are dy/dx = -x/y and dy/dx = e^y * (-1/x² + 1/y²).

What is the differential equation?

A solution of a differential equation is an expression for the dependent variable in terms of the independent one(s) which satisfies the relation. The general solution includes all possible solutions and typically includes arbitrary constants (in the case of an ODE) or arbitrary functions (in the case of a PDE.)

a) To differentiate x² + xy + y² = 0 with respect to x, we can use the power rule and the chain rule.

The power rule states that the derivative of x^n is nx^(n-1)

The chain rule states that if y = f(u) and x = g(u) then dy/dx = dy/du * du/dx

x² + xy + y² = 0

dx/dx (x² + xy + y²) = dx/dx (0)

2x + y = 0

dy/dx = -x/y

b) To differentiate 1/x + 1/y = e^y with respect to x, we can use the chain rule and the reciprocal rule.

The chain rule states that if y = f(u) and x = g(u) then dy/dx = dy/du * du/dx

The reciprocal rule states that the derivative of 1/x is -1/x²

1/x + 1/y = e^y

dy/dx = dy/dx (e^y)

dx/dx (1/x + 1/y) = dx/dx (e^y)

-1/x² - 1/y² = e^y

dy/dx = e^y * (-1/x² + 1/y²)

Hence, the differential equations are dy/dx = -x/y and dy/dx = e^y * (-1/x² + 1/y²).

Answer:

For 3 books, costs are the same

$59

Step-by-step explanation:

x = number of books

$41 + ($6/book)(x) = $32 + ($9/book)(x)

41 - 32 = 9x - 6x

9 = 3x

x = 9/3 = 3

41 + 6(3) = 32 + 9(3) = $59

Answer:

Area = length x width (in feet)

Step-by-step explanation:

The area of a 2-dimensional shape can be found by multiplying its length by its width. The equation to find the area of a rectangle is:

Area = length x width

So if you know the length and width of a piece of glass in feet, you can use the above equation to find its area in square feet. For example, if the length of the glass is 10 feet and the width is 5 feet, the area would be:

Area = 10 feet x 5 feet = 50 square feet

So the equation to find the area of a piece of glass in square feet is:

Area = length x width (in feet)

It's worth noting that this equation applies to any 2-dimensional shape that has a length and a width, not just a rectangle.

Answer:

answer is d

Step-by-step explanation:

Answer:

  $3213

Step-by-step explanation:

You want to know the total spent on rent and food if rent is 7/20 of your budget and food is 1/2 of your budget of $3780 per month.

The amount spent on each item is the product of the fraction of the budget it is and the total amount being budgeted (your income).

  rent = 7/20 × 3780 = 1323

  food = 1/2 × 3780 = 1890

The total spent on these items is the sum of these amounts:

  rent + food = 1323 +1890 = 3213

A total of $3213 is budgeted for rent and food.

__

Additional comment

Your calculator can figure this handily.

You can factor out the income amount and add the fractions first:

  (7/20·3780) +(1/2·3780) = 3780(7/20 +1/2) = 3780(7/20 +10/20)

  = 3780(17/20) = 3213

Answer:

The independent variable, x, represents the number of years working at the company. The dependent variable, C(x), represents the salary. The salary depends on the number of years working at the company because the salary increases by $2,000 for each year of work. A function relating these variables is C(x) = 35,000 + 2,000x, where x is the number of years working at the company and C(x) is the salary. So C(4) = 35,000 + 2,000(4) = $43,000 meaning that if Emily works for 4 years, her salary will be $43,000.

The elevation of mountain mt.kenya is, x = 17,057.1 feet by substitution method from the elevation of mountain K2 given.

Given that,

K2 is 11,194.21 feet higher than mt.Kenya, write and solve an equation to find the elevation of mt.Kenya.

x = mt. Kenya ( since given that x represents the elevation of mt.kenya)

Let us consider/assume ,

y = K2 (say)

Therefore, the relation between x and y:

                   x = y - 11,194.21    ( or )

                   y = x + 11,194.21  

( since given that K2 is 11,194.21 more than mt.Kenya )

The elevation of K2 Mountain = 28251.31 feet

                                                  = y

substitute the value of y in x = y - 11,194.21

                                            x = 28251.31 - 11,194.21

Answer:

  g(x) = e^(x+2) -3

Step-by-step explanation:

You want the transformed function g(x) of the parent function f(x) = e^x given that g(x) has a horizontal asymptote of -3 and goes through the point (-2, -2).

The parent function goes through the point (0, 1), which has apparently been translated to (-2, -2) by the transformation. That translation looks like ...

  g(x) = f(x -h) +k . . . . . . . . f(x) translated h units right and k units up

Our function has been translated from 0 to -2 in the horizontal direction, or left 2 units: h = -2.

It has been translated from 1 to -2 in the vertical direction, or down 3 units: k = -3.

Then the translated function is ...

  g(x) = f(x +2) -3

  g(x) = e^(x+2) -3

The area of a trapezoid is given by the formula A = 1/2(b1 + b2)h. In this case, b1 = 4, b2 = 3, and h = 8.

The area of a trapezoid can be determined using the formula A = 1/2h(b1 + b2), where A is the area, h is the height, and b1 and b2 are the lengths of the top and bottom bases of the trapezoid, respectively. To determine the area of a child's toy harp in square inches, we need to know the length of the top and bottom bases and the height of the trapezoid.

Therefore, the area of the harp is 1/2(4 + 3)8 = 20 square inches. To find the area of the harp, we first need to know the measurements of the base lengths, b1 and b2, as well as the height, h. Once we have these measurements, we can plug them into the formula for the area of a trapezoid and solve for A. In this case, the area of the harp is 20 square inches.

You need to find the four constants, a, b, c, and d. At x = -1000, you have a value for f(x).

A)Outline it:

f(-1000) = -1000 = a (-1000)^3 b(-1000)^2 + c (-1000) + d

At x = 1000, you have a value for f(x).

B)Outline it:

f(+1000) = a (1000)^3 + b (1000)^2 + c (1000) + d

You know the slope's value, f'(x), and when x = -1000, f'(-1000) equals 3 a (-1000)2 + 2 b (-1000) + c.

At x = + 1000 f'(1000), you have a value for the slope: 3 a (1000)2 + 2 b (1000) + c

C) That is four linear equations with a, b, c, and d as the four unknowns.

When you simultaneously solve all four equations, you will get the function and its derivative, which you may graph.

D) The steepest part is where the derivative's absolute value is at its highest.

You can find that extreme by setting the derivative of the derivative equal to zero.

The graph demonstrates that the function g's line goes through the locations (0,2) and (2,8). The slope of the line is 3, implying that its equation is g(x) = 3x + 2.

The steepness or inclination of a line, route, or surface is measured by slope. It is the vertical distance divided by the horizontal distance between two locations on a line, route, or surface.

According to the graph, the function g is a line with a slope of 3 and a y-intercept of 2. This suggests that the line's equation is g(x) = 3x + 2. According to this equation, increasing the y-coordinate by one increases the x-coordinate by three. The line connects the points (0, 2) and (2, 8), which means that when x = 0, y = 2 and when x = 2, y = 8. This may be demonstrated by plugging the x-values into the equation, which will produce the matching y-values.
