Calculus

The perimeter is the sum of all segments that make up a closed figure. You need to know what type of figure you are talking about - for example, a rectangle, triangle, etc. You also need to have enough information to calculate the length of each side. Once you have those, you can add them.

Domain = set of points at which a function exists

Range = set of points which are mapped to by the function

For example,

if f(t) = 1/t

=> domain is all real numbers except for t=0, since 1/0 is an mathematical error

and: range is all real numbers except for f(t) = 0 since you cannot actually obtain this value by inputting a value for t.

Without any equality sign and not knowing the plus or minus values of the given terms it can't be considered to be an equation.

Not enough information has been given to determine the value of x

-log(1.2 X 10^-5 M H(+))

= 4.9 pH H(+)

It depends on which angle beta is: the angle subtended by the arc at the centre of the circle (assuming that it is a circle and not an ellipse or some other shape), otr the angle subtended by the chord and one of the radii. Basically, there is not enough information provided in the question to give a sensible answer.

Pi was calculated to 10 trillion digits on October 17, 2011.

23 and one half is larger.

divide 100 by the initial value and times by the new value, then take 100 from the total.

There is a rare group of people who can't, they're the lucky ones.

When you get extremely angry your bones crack and you transform into a werewolf.

Most people go to anger management to control this but others don't care.

It's easier to pretend it doesn't happen :)

The motion will not be effected. If you build a pendulum in your garage that swings with a period of one second, then bring it on a train, it will again swing with a period of one second, provided the train moves uniformly.

None. Infinity never ends, so nothing can be larger than it.

There are more than 1 set of values that will work. The value's of "x = 1" and "y = -1.5" will work and therefore the values "x = 100" and "y = -150" will work as well. In other words take any number you want for the value of x and multiply that number by negative 1.5 (-1.5) to get the value of y.

y = (x multiplied by -1.5)

x2 + y2 = x2 - 2xy + y2 + 2xy = (x - y)2 + 2xy = 72 + 2*8 = 49 + 16 = 65

You could, instead, solve the two equations for x and y and substitute, but the above method is simpler.

n:=1 to FactorialLimit do % Step

ok well first you have to use order of operations: first multiply then subtract, let me know when you get an answer!!

Hope this helps!!

Any set of answers that make one sentence will make the other correct. y=2x is the same as 2y=4x because (1,2) and (3,6) would make these correct.

20X - 3 + 3X = 11X + 5 - 8

put those like terms together on the left

23X - 3 = 11X + 5 - 8

like terms together on the right

23X - 3 = 11X - 3

this equation admits of no solution, so is not true

X would = 0
