consider the function f (x, y) = 1 x2 y2. draw a contour map for f (x, y).

The ice cream costs $0.10 and the pie costs $2.10.

Let's call the cost of the ice cream "x".

According to the problem,

The pie costs $2 more than the ice cream, so the pie costs x + $2.

And, together, the pie and ice cream cost $2.20, so:

x + (x + $2) = $2.20

Expanding and solving for x:

2x + $2 = $2.20

2x = $0.20

x = $0.10

A linear equation is an algebraic equation with simply a constant and a first-order (linear) component of the form y=mx+b, where m is the slope and b is the y-intercept.

The above is sometimes referred to as a "linear equation with two variables," where y and x are the variables.

Ax+By=C is the typical form for linear equations in two variables.

2x+3y=5, for example, is a simple linear equation.

It is rather simple to get both intercepts when an equation is stated in this way (x and y).

The distance between the bird and its prey is 19 feet. The solution has been obtained by using trigonometry.

What is trigonometry?

The study of the sides, angles, and connections of the right-angle triangle is the main goal of the field of mathematics known as "trigonometry."

We are given that the angle on f depression between a bird and its prey is 70%.

This means that Theta = 70°

Also, the height of the bird from the ground is 18 feet.

Using trigonometry, we get

⇒sin theta = perpendicular side/hypotenuse

⇒sin 70 = 18/hypotenuse

⇒Hypotenuse = 18/sin 70

⇒Hypotenuse = 19.1 ≈ 19 feet

Hence, the distance between the bird and its prey is 19 feet.

Answer: (14) x (-2)- (11) x (-21)

Step-by-step explanation: Hope I was I right!

Parallelogram is the closed shaped quadrilateral which has opposite site equal and the opposite angle are equal. The value of the x is 3 units.

A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus. Angle T for a parallelogram is (40x+2) degrees.

R is a 122 degree angle.

[tex]$$\angle T=\angle R$$[/tex]

Put the values of the angle in the above equation. Thus,

[tex]& 40 x+2=122 \\[/tex]

This double integral evaluates to a value of 2/3 x

What is double integral?

Double integral is a type of integration which involves the integration of two variables. It is used to calculate the area or volume of a function of two variables. This type of integration is used to solve problems in areas such as physics, engineering, probability and statistics. Double integration can be used to calculate the center of mass of a two-dimensional object, or the moments of inertia of a two-dimensional object. In its most basic form, this type of integration involves the calculation of a limit where two variables are integrated with respect to each other.

To evaluate the double integral, one must use the formula for the area of a two-dimensional region: ∫∫f(x, y)dA = ∫∫f(x, y)dxdy. The limits of integration of the region D must also be taken into account. Thus, the double integral can be evaluated as follows:

∫∫(x^2-1)dA = ∫ 0 to 1

∫ 0 to x (x^2-1)dx dy = 2/3 x

This double integral evaluates to a value of 2/3 x

The value of variance Var(X) is 2

We know that the mean is nothing but the central value of the data and the variance represents the deviation of the data from the mean.

As we know Var(X) = E(X²) − (E(X))²

So, Var(X²) would be,

Var(X²) = E((X²)²) − (E(X²))²

Var(X²) = E(X⁴) − (E(X²))²

Substitute the values Var(X²) = 5 and E(X⁴) = 14 in above equation.

5 = 14 - (E(X²))⁴

(E(X²))² = 14 - 5

(E(X²))² = 9

E(X²) = 3

Now we subatitute the values E(X²) = 3 and E(X) = 1 in equation Var(X) = E(X²) - (E(X))²,

A symmetrical graph is one that looks the same on both sides of a centre line. This indicates that the y-values of the points on the graph that are the same distance from the centre line are the same. This results in a symmetrical graph that is aesthetically consistent and easy to understand.

In the given question, Dean is mistaken since the graph is symmetrical.

Y intercept is the Y value when x is equal to 0. In the point (0,1) x is 0 and y is 1, so the y-intercept is 1.Slope is-1/4.

When a line crosses the y-axis on a graph, that location is known as the y-intercept.It is always 0 for the associated x-coordinate.

By calculating rise over run, the slope can be determined.This is accomplished by splitting the discrepancies between the y- and x-coordinates. The values of the y-intercept and slope reveal details on the nature of the relationship between the two variables, x and y.

The slope is the change in Y over the change in x:

Slope = (0-1) / 4-0) = -1/4

Slope = -1/4

Y intercept is the Y value when x is equal to 0. In the point (0,1) x is 0 and y is 1, so the y-intercept is 1.

Thermometers are calibrated using a variety of temperature scales that traditionally drew their definition from different reference points and thermometric materials.

Reason

The phase change that takes place when a solid melts into a liquid or a gas condenses into a liquid keeps the temperature constant while the thermal energy changes. the second choice is the right one.

When a system's temperature rises in a calorimetry problem, T > 0 and Q > 0. the third choice is the best one.

To write an exponential function in the form y = ab^x that goes through the points (0,11) and (2,396), we can use the fact that the exponential function is defined as y = ab^x, where a is the initial value and b is the growth factor.

First, we can find the growth factor by using the following equation: b = y2/y1.

In this case: b = 396/11 = 36

Next, we can use the point (0,11) and the growth factor to find the value of a.

Since we know that y = ab^x, we can substitute the point (0,11) and the growth factor into the equation:

11 = a(36)^0

a = 11

So, the exponential function that goes through the points (0,11) and (2,396) is: y = 11 * 36^x

It is important to note that the above function will pass through the points (0,11) and (2,396) but it may not pass through any other points. It is also a good practice to check the function by substituting the point (0,11) and (2,396) to confirm it gives the correct output.
