3. Let f(x)=log4 x. What are the values of
f(64), f(1/4), f(square root 4)

What is sin 7x/4 ? i need on this urgent trig

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1
