Evaluate ƒ(x ) = x 2 + 1 for ƒ(-1). can someone explain how you figure this?

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

The area (a) of a circle with a radius of r is given by the formula and its diameter (d) is given by d=2r. arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.

Si el duplo del mayor de dos numeros se divide entre el el triplo del menor, el cocient es 1 y el residuo 3, y si 8 veces el menor se divide por el mayor, el cociente es 5 y el residuo 1
