I have a math final tomorrow, and need to know how to use identities and what they are. Could somebody please list them and say what they relate to?
Easy 10 points. Thanks!-Identities are equations
it says:
rationalise 6+√8 / √2
and the answer must be in the form of p√2+q
please tell me how to solve this! thank you!-multiply the top and bottom by √2
you then get (6√2 + √16)/2
which become (6√2 +
Okay the variable is x.
Here is the scenario...
Mrs Menedez needs to buy candy for treatbags that will be given to every child attending her daughter Rositas birthday party. Each bag will contain a
A particle moves in a line with position at time t given by 30t − 4t^2
(a) Find the average velocity for the interval of length 0.5 sec ending at t = 3
(b) Find the velocity at the instant t = 3 usin
As exact as possible would be extremely appreciated! Thank you in advance-9.273726921930792e+020
im missing the last five digits, but you can sum the last five digits of all the 100 numbers without ca

This is not an identity
Q1. Find all positive intergers less than 50,00 that have precisely 11 divisors
Q2 Can the sum of the first n consecutive positive intergers be equal to the square of a prime number?
Q3. Find all posi
Obtain f ’’ (0.3) forthe following:
(1)f(x)=arccosx
With clear explaination if you could please.
Thanks in advance-This is a standard derivative. Use:
If f(x) = arccos(ax)
then f(x) = - a/[sqrt(1
An absolute value function is given: f(x)=-2|x-1|=5
Determine the domain and range of the function.
What is the answer and how do you solve it?-Solve by plugging #s in for x. All f(x) really is is (y
f(x) = 4x^2 - 24x + 41
The vertex form of a quadratic equation is:
f(x) = a(x-h)^2 + k
Complete the Square to get the equation in Vertex Form:
f(x) = 4(x^2 - 6x) + 41
= 4(x^2 - 6x + 9) - 36 + 41
=
Find the equation of the line that is perpendicular to x = -1 and passes through (-2,-3)
Could you also tell me how you get the answer, including what concepts you used. Thanks!-two points that are in
A farmer has to plant seeds in a triangular field. He knows that the middle row, row 26, needs 4025 seeds, and that the last row needs 7525 seeds. If the number of seeds planted in each row follows an
prove the identity-2tanA /(sec^2A)
=[ 2 sin A / cos A ] / [ 1/ cos ^2 A]
=[ 2 sin A / cos A ]cos ^2 A
= 2 sin A cos A
= sin 2A
proved-1 - sin 2x

Q: what is the ratio of average energy/m(squared)/year for producers compared with consumers?
consumers average: 799.6
producers average: 5611.6
my answer: 5611.6 divided by 799. (5611.6 / 799) which
