Note that if the family is to spend less than $60 dollars without further expenses, then they will have to spend nothing more than 6 hours. The inequality expression is given as: 36+4h < 60

First, the inequality expression is given as:

36+4h < 60

Where h is the number of hours they could spend.

We arrive at the above because we were given the following:

Cost of Movie = $36

Cost of parking Per Hour= $4

The maximum amount to be spent = $60

Thus, to find the number of hours the can spend without overshooting $60, we must find h. To do this, we must make h the subject of the formula by first removing 36 from both sides:

36+4h-36 < 60-36

4h < 24

h < 24/4

h < 6

What the above result show is that the number of hours that must be spent must be less than 6.

The general solution to x squared dy over dx equals 3 plus 2y is given by 1/2 ln|3 + 2y| = -1/x + c, where c is an arbitrary constant.

To calculate this, we begin by taking the derivative of both sides of the equation with respect to x. We then rearrange the equation to yield 2y + x^2 dy/dx = 3. We divide both sides by x^2 so that dy/dx is isolated on one side of the equation, yielding dy/dx = (3 - 2y) / x^2. We can then integrate both sides of the equation, with respect to x, to yield 1/2 ln|3 + 2y| = -1/x + c, where c is an arbitrary constant. This equation is the general solution to x squared dy over dx equals 3 plus 2y.

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.

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

                                       ∴ x = 17,057.1 feet.

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:

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: k=10

Step-by-step explanation:

The probability mass function of x  is P(0)= 1/8, P(1)= 3/8, P(2)= 3/8, P(3)= 1/8.

Here number of trials = 3

In tossing a coin for once, the outcomes of the trial are either head or tail.

The trials are independent.

probability of getting head(success)=p=1/2

probability of getting tail(failure)=1-p=1-(1/2)=1/2

Number of success=X

Since there are two mutually exclusive outcomes of independent trials, the probability mass function of Binomial = (nx)px(1−p)n−x(nx)px(1 − p)n−x {in this case n=3}

The probability distribution of X is -

= X=0, P(X=0)=1/8

= X=1, P(X=1)=3/8

= X=2, P(X=2)=3/8

Notice that x is on the denominator, so we can't evaluate that function on x = 0.

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.
