The area of a rhombus is given by the formula a=1/2xy, where x and y are the lengths of the diagonals. if the diagonals of a rhombus have lengths 10cm and 20cm, find the area of the rhombus.

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit
