Use the inner product ⟨f, g⟩=∫10f(x)g(x)dx
in the vector space C0[0,1] of continuous functions on the domain [0,1] to find ⟨f, g⟩, ∥f∥, ∥g∥, and the angle αf, g between f(x) and g(x) for
f(x)=−5x2−3 and g(x)=−6x−4.

8 2/3 is the answer

step-by-step explanation: just use a calculator

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

3x + 4y -25 =0 represents the amount of change sianna should recieve

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
