Help Frustrated With Math Functions

Im so frustrated I cant seem to figure out these problems.If anyone cant solve these problems its ok just an effort will be helpful. 1. Let F(x)=x²-4 and G(x)=6-xFind (F-G)(10)(F-G)(10)= 2. Let F(x)

What is the derivative of Csin(wx), where C and w are constants

I understand that the derivative of sin(wx) is (w)cos(wx), but what if there is a constant C in front? Thanks!!-First, use product rule: f(x)g(x) = f(x)g(x) + f(x)g(x) At the same time, you are using

If a question says "The answers are integral" what does it mean

Algebra solving equations.-Integral is just an adjective for integer. An integer is any whole number, positive or negative, but an integer cannot have a decimal (i.e. 2.3 is NOT an integer, 5 IS an in

You are on a swing 3.8 m long. your maximum displacement 17° from vertical, how fast will you be @ the bottom

The question says it all, but please dont give me the answer, I am trying to learn :)-Height gain = 3.8 - 3.8*cos17 = 0.166 m mg*0.166 = 0.5m*v^2 v^2=3.256 v = 1.8 m/s-Easiest way to solve this is to

Remainder theorem 10 pts

The polynomial 2*x^2 + 6*x +3 has the same remainder when divided by x + p or by x - 2q , where p does not equal to -2q. Find the value of p - 2*q. please help me with the workings-Remainder Theorem:

Can someone please help me with this math problem.....

How many even and odd positive factors does1200 have

I know how to list all the factors, but please solve this using prime factorization. 1200=2^4*3*5^2,which means it has 30 factors(5*2*3), but what now? how many even and odd positive factors does it h

Prove the following identity: cos5x - cos3x = -8sin^2x(2cos^3x - cosx)

Note that, by the sum-to-product identities: cos(A) - cos(B) = -2sin[(A + B)/2]sin[(A - B)/2]. So, with A = 5x and B = 3x: cos(5x) - cos(3x) = -2sin[(5x + 3x)/2]sin[(5x - 3x)/2] ==> cos(5x) - cos(3x)

Product of 3 integers in arithmetic progression is a prime. What are they

Call the middle number a, and call the common difference d.Both a and d must be integers. Your numbers are a-d, a, and a+d. Their product must be (a-d)(a)(a+d) This is (a^2 - d^2)(a). But lets thin

Calculus prerequisite problem help!

15X^(5/2)-2x^(3/2)-24x^(1/2)can someone please show how to factor this problem using GCF?-15 * x^(5/2)-2 * x^(3/2)-24 * x^(1/2) => x^(1/2) * (15 * x^(4/2) - 2 * x^(2/2) - 24) => x^(1/2) * (15x^2 - 2x
