There is not one exact single book to recommend for the study of the calculus of empty linden current and multivariate analysis but the books ‘Adams and Essex: Calculus’ and ‘Differential equations, linear algebra and its applications’ have often been used for one-dimensional and multidimensional ...

In school, we all memorized maths and its problems and formulas, but we never really paid any attention to the idea behind mathematics overall. The history of mathematics dates back to ancient civilization times, but when it comes to thinking about how mathematics came into being, the question ...

Suppose the percentage of people who took the train is x, equal to 100%. According to the question, 80% more people took the bus from the station than the train. That would, in turn, make 180% of people who took the bus since 100 and 80 more is equal to 180 (100+80). Let y be equal to the percentage ...

Nowadays, most science books, more or less, cover the same syllabus. However, there will be some minor changes like one book might focus on one particular topic more than the other or one might have well-explained examples and the other might have difficult to understand language. In general, all of ...

I am not sure my answers is right or not but i did this
Show the number as ABC
Reverse them, you get CBA where,
A. = hundred
B. - tens
C. = Units

So,
Hundreds Tens Units
A B C
C B A
SUBTRACT A – C O C – A
Subtract 1 hundred, add 9 tens and 10 ones
(-100, +90, +10 – 0)

Hundreds Tens Units ...

(3x)² = x ² + P ²
9x ² - x ² = P ²
√8x ² = P
P = 2√2 x
½ multiplied by x multiplied by 2√2 x = 48
√2x ² = 48
X ² = 48/ √2
½ x√8 x ² = 48
x. √2 . 2 . X = 48
x² . √2 = 48
X² = 48/ √2
X = √48/ √2

Hence, H = 17.48
B = 5.826
P = 16.478

This condition is completely normal. It has happened with most of us when we get confused in mathematical formulas, mix them or forget them. It happens when you can't remember the power of "a" in the quadratic formula. What you need is to stop cramping yourselves with the formulas. You need practice ...
