Which function has a range of {y|y <5}?

f(x) = (x – 4)2 + 5
f(x) = -(x – 4)2 + 5
f(x) = (x – 5)2 + 4
f(x) = -(x - 5)2 + 4

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

Consider the triangle. which shows the order of the angles from smallest to largest? angle a, angle b, angle c angle b, angle a, angle c angle b, angle c, angle a angle c, angle a, angle b

Express -5 2/5 as an improper fraction.
