To see the answer more clearly, we can sketch the function. First, we start by sketching the parabola (curve). If we have a positive x^2 term then we have a U shaped parabola and if it is negative, i.e. -...

5×4=20 common denominator what did you do to 5 to get to 20? X4, therefore you have to 3x4=12what did you do to 4 to get to 20? X5, therefore you have to 1x5=5
12/20 + 5/20= 17/20

The Atkinson & Shiffrin Multi Store Model of Memory is a structural model that helps to explain how information is transferred from the environment into our short-term and long-term memory. The model ...

The heart could be compared to a pump but the key differences lie in its exquisite ability to self control. Through local mechanisms (e.g. Frank-starling mechanism) and external mechanisms (e.g. neurol or...

Start by expanding out Rsin(2x+a) using the addition formula for sin, sin(A+B) = sin(A)cos(B)+cos(A)sin(B). Substituting 2x = A and a= b, we get that Rsin(2x+a) = R(sin(2x)cos(a) + cos(2x)sin(a)) = Rcos(a...
