Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

What is the conjugate of 11 plus 17i?
11 + 17i is an IMAGINARY number. .
Its conjugate is 11 - 17i
NB Note the change of sign only.
What is the 5th root of 4 in exponential form and why?
Not quite sure on the mathy answer here, but...............
sqrt(X)
= X1/2
--------------so, in similar fashion
5root(4)
= 41/5
--------------------a number a little over 1 and taking a number to a fractional power is, the numerator is the exponent of the number under the radical and the denominator is indicative of the root taken of the number.
You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. But since you seem unable to carry out even this simple task, the answer is 1.75
How do you solve the equation 2x plus 30 equals equals 12x-50?
Subtract 2x from each side: 30 = 10x - 50;
Add 50 to each side: 80 = 10x
Divide each side by 10: 8 = x

13
In algebra, any letter represents anything. So if 13y = 26 then y is 2.
13 y is 13 x ? <<< it could be anything.
The multiples of 20 are: 20,40,60,80,100,120,140,160,180,200,220.... The list goes on and on.
Is a 2 gallon bowl too small or too large for a goldfish?
It is much too SMALL. 1 goldfish needs a minimum of 10 gallons of water. It must also have a permanently running 'cycled' filter and it must also have at least 50% of its water replaced every week. It is preferable to keep the goldfish in a larger tank so that two or more can be kept, as goldfish are social fish.
A two gallon bowl would be suitable for a single male betta IF and ONLY IF a suitable small filter can be found that does not disturb the surface of the water too much, and a heater can be found that does not present an electrical hazard in such a small tank - 25 watts or less. If no heater is available, you could keep a single paradise fish provided the tank has a filter. I strongly recommend that you don't attempt to keep any fish in a tank smaller than 5 gallons, especially if you are a beginner, because it is so much more difficult to keep the water quality good in such a small volume of water.
How do you solve -2x plus y equals -3 and -x plus 2y equals 3?
Simultaneous equations
-2x + y = -3
-x + 2y = 3
Multiply the bottom equation by '-2'
Hence
-2x + y = -3
2x - 4y = -6
Add the two equations
-3y = -9
Divide both sides by '-3'
y = (+)3
Substitute in to either equ'n for 'x'
-2x + 3 = -3
Subtract '3' from both sides
-2x = -6
Divide both sides by '-2'
x = (+)3
Hence (x,y) = ( 3,3)
How many squares on a chessboard?
Number of 1x1 squares= 8*8=64
Number of 2x2 squares= 7x7=49
Number of 3x3 squares= 6x6=36
Number of 4x4 squares= 5x5=25
Number of 5x5 squares= 4x4=16
Number of 6x6 squares= 3x3=9
Number of 7x7 squares= 2x2=4
Number of 8x8 squares= 1x1=1
Total number of Squares= 8^2+7^2+6^2+...+2^2+1^2= 204
What is x2 plus 3x-18 divided by x-3?
x^2 + 3x - 18
Factor
( x + 6)(x - 3) / (x- 3)
Cancel down by 'x-3'
Hence the answerr is x + 6
How do you work this out 5 plus 4 x 2 equals 13?
5 + 4 x 2
Always do the multiplication/division before addition subtraction. ; mathematical rule. #
5 + 8 = 13
What method would be used to solve this linear equation 2x-3y equals 24 and 2x plus y equals 8?
I would use substitution. Turn the second equation into y=8-2x, put it into the first and solve for x. Then put x into one of the equations and solve for y.
So...
2x-3(8-2x)=24 --> 2x-24+6x=24 --> 8x=48 --> x=6
y=8-(2x6) --> y=8-12 --> y=-4

9x - 8 = 55
Add '8' to both sides
9x - 8 + 8 = 55 + 8
Hence
9x = 63
Divide both sides by '9'
9x/9 = 63/9
x = 7
NB Remember in mathematics , the four functions add(+), subtract)-), multiply(x) and divide (/) , whatever you do to one side of the 'equals(=) , you must do to the other , in order to preserve equality. Its like a balance scales, you MUST keep it in balance.
