If the projectile is released at an angle, it will have 2 components: 1. horizontal component of motion and 2. vertical component Horizontally, the projectile is assumed to travel at a constant speed (ie ...

Suppose f(x)=x²+4 and g(x)=3xg(f(x)) would therefore be 3(x²+4) and that equals 3x²+12the next step would then be to substitute x with 1 to find the solution for (g(f(1))....

Using the quadratic formula with a calculator a=1 b=1 c=-90 answers are n=-10 and n=9Factorising (n-9)(n+10)=0 answers are n=-10 and n=9

The unsimplified form of the derivative can be obtained fairly easily with use of the quotient rule. The trick for simplification is to multiply top and bottom by (x+4)^0.5, this allows manipulation of th...

Firstly, integrate each term individually, starting off with the 3x^4. In order to integrate the index on the x term needs to be raised by 1, and the coefficient of the x should be divided by this new val...
