Find the perimeter of each figure.

Answer:

Ascend

Step-by-step explanation:

In order to solve this problem, we are going to use some principles of vector calculation. The concepts we are going to use are Partial derivatives, gradient vector, velocity vector, direction vector, and directional derivative.

The gradient vector is a vector that describes how is the 'slope' in the space of a multivariable function at a specified point; it is built as a vector of partial derivatives. The vector velocity is a vector that describes the direction and speed of the movement of a body, if we make the velocity a unitary vector (a vector whose norm is 1), we obtain the direction vector (because we are not considering the real norm of the vector, just direction). Finally, the directional derivative is a quantity (a scalar) that describes the slope that we get on a function if we make a displacement from a particular point in a specific direction.  

The problem we have here is a problem where we want to know how will be the slope of the hill if we stand in the point (120, 80, 764) and walk due south if the hill has a shape given by z=f(x,y). As you see, we have to find the directional derivative of z=f(x,y) at a specific point (120, 80, 764) in a given displacement direction; this directional derivative will give us the slope we need. The displacement direction 'u' is (0,-1): That is because 'y' axis points north and our displacement won't be to the east either west (zero for x component), just to south, which is the opposite direction of that which the y-axis is pointing (-1 for y component). Remember that the direction vector must be a unitary vector as u=(0,-1) is.

Let's find the gradient vector:

Evaluate the gradient vector at (120,80) (764 is z=f(120,80); you may confirm)

Finally, find the directional derivative; if you don't remember, it can be found as a dot product of the gradient vector and the direction vector):

As you see, the slope we find is positive, which means that we are ascending at that displacement direction.

The ratio between two numbers can be written in terms of fraction by writing the first number as numerator and the second number as denominator. The ratio of the given two boxes is 0.6.

What is the application ratio and proportion?

A ratio is the relation between two numbers a and b as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

Given that,

The cost of 8 ounce box is $12,

The cost of 12 ounce box is $16,

And, the cost of 16 ounce box is $20.

The ratio of two numbers a and b is given as a : b =  a / b.

Thus the ratio of the cost of an 8 ounce box to a 16 ounce box is given as,

12 : 20

= 12 / 20

= 0.6.

Hence, the ratio between the cost of the two boxes is 0.6.

Answer:

3 dollars per pound

Step-by-step explanation:

First, you find the cost of a box of granola 4.5/2 = 2.25. Since there are 12 ounces of granola in each box, you could divide 2.25 by 12 to get the cost of granola per ounce(0.1875) and multiply it by 16 to get the cost of a pound (3).

To write each combination of vectors as a single vector, we can simply add them together. For example, to write the combination of vectors AB + BC as a single vector, we would simply add the vectors AB and BC together.

Here is how to write each combination of vectors as a single vector:

AB + BC = AC

CD + DB = CB

DB - AB = BD

DC + CA + AB = AD

Here is a diagram to help visualize the addition of vectors:

[Diagram of vector addition]

In the diagram, vectors AB and BC are added together to create vector AC. Vector AC is the sum of vectors AB and BC.

We can also use the following formula to write the combination of vectors as a single vector:

A + B = (A_x + B_x, A_y + B_y)

where A_x and A_y are the components of vector A, and B_x and B_y are the components of vector B.

For example, to write the combination of vectors AB + BC as a single vector, we would use the following formula:

AB + BC = (AB_x + BC_x, AB_y + BC_y)

where AB_x and AB_y are the components of vector AB, and BC_x and BC_y are the components of vector BC.

Answer:

11

Step-by-step explanation:

D+16/3=17 the steps?

1. D+16/3=17

Divide 16/3.

D+6 = 17

2. subtract 6 from both side.

D = 11.
