The following problem must be solved using matlab, i need to understand how to do these by myself so the ss have to b clear in order to learn how to use the tool.
(geogebra, mathematica, wolfram alpha, etc could be used as well, however it must be indicated whigh software tool has been selected)
the answer must include:
-screenshot of the code used in each problem.
-specify the software used to solve the problems, in case of having used different softwares indicate in each problem which one was used.
-graph and / or table thrown by the code used, if the problem requires it.
problem:
obtain the graph of the following vector field: b) f(x, y, z) yî - 2j + xk|

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

the answer will be b x² +x-1

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
