Passes through (2, 3) and has slope of -1/2

An objects motion is described by the equation d= 4sin (pi t) what will the height of the object be at 1.75 seconds?

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

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76
